The Best Roomba to Get in 2019 - with Model Comparison Chart

The Best Roomba to Get in 2019 – with Model Comparison Chart

Last Updated: May 27, 2019

With the release of the Roomba i7 and e5 last year, there are almost too many robot vacuums from iRobot to choose from. It’s impossible to know which Roomba to buy without doing a little bit of research.

Deal Alert :

Amazon has a great discount on the Roomba 960 today. With the savings available today, the 960's performance to price ratio simply can't be beat. 

Choosing a Roomba should not be so hard. As good as Roombas are, the information found on manufacturer iRobot’s official website can be vague and somewhat misleading.

The i7+ is arguably the most sophisticated robot vacuum on the market today, but not every feature is a must. Different households have different needs from their robot vacuums. You don’t want to spend this much on a robot vacuum and not have it live up to your expectations. It’s hard to know which features you need and which ones are just marketing fluff.

That’s where this guide comes in. This guide is the result of my personal experience with Roombas and over 25 hours of exhaustive research. Plus updates every time a major model is released.  After reading it, you should have pretty good idea of which model will best suit your needs. 

You will find out what makes each Roomba model different from another, what to like and what not to like, and which Roomba is best for specific situations (pets, long hair, multilevel homes, etc). Only the best reviewed Roomba models are included in this review to keep the information relevant and digestible. Models that have been discontinued are deleted in an attempt to keep this guide concise. (I know not everyone wants to read 10 pages about vacuum cleaners.)

Summary

If you don’t have time to read the whole article, here is the 2 minute version:

👉 If you are on a tight budget and don’t mind occasionally cleaning out trapped hair from the brushes and a random cleaning pattern: get the Roomba 675

👉 If you want a good balance of price and features: go with the Roomba 960

👉 If you want the most advanced robot vacuum on the market right now (but don’t need self-emptying): get the Roomba i7. It’s a better vacuum than the previous reigning champion (Roomba 980) AND it is cheaper. It can also be upgraded to the i7+ if you decide later you want it to empty itself when full.

👉 If want a self-emptying robot vacuum and money is no object, the Roomba i7+ is for you.

Roomba 650 

In short: “The Most Basic Roomba”

Oh how Roombas have improved in the past couple years. The Roomba 650 used to be so good! Sadly this is no longer the case. It used to be the best selling Roomba because of its winning combination of price and features. But with newer models released, I can no longer recommend this Roomba because the newer models hands down blow it out of the water.

Having said that, there are still plenty of things to like about the 650. Three years ago, I would have recommended this model in a heart beat. Roombas use a psuedo-random pattern to navigate around your house, which actually results in a better cleaning outcome, especially on carpet. It’s programmable and self-docking, meaning you can have it start itself when you are away and come home to a clean floor and docked Roomba. Owners rate the Roomba 650 very highly. It does a great job picking up dirt and hair. It is able to get under most furniture, cleaning areas you normally can’t get to with an upright vacuum.

Now onto the main reason why I don’t recommend this model anymore–the rotating brushes. Designed like a conventional vacuum, the 650 picks up dirt by agitating the carpet or floor with a rotating brush. This works great in terms of producing clean floors, but becomes a headache when hair gets stuck in the vacuum. I hate this on my upright vacuum because I have to take a knife and start cutting the hair out of the brushes. With the Roomba 650, it’s slightly easier because the brushes are removable and iRobot includes a hair extractor to make the process easier. Still, it’s not a pleasant task.

Only choose the 650 if price is your one and only criteria. However, I think most people should skip the 650 and pick a better model, like the Roomba 860. The brushless rollers alone on the upgrade are worth every penny.

Areas needing improvement:

  • Hair gets stuck in the rolling brushes, making maintenance a tedious task.
  • Old version of Virtual Wall accessory requires 2 C batteries, which are not included.

Bottom Line:

  • Even if price is the only concern, I would still recommend skipping this model

Roomba 690

In short: “The Roomba 650 but with WiFi and app support”

The Roomba 690 was introduced in 2017 to compete with similarly priced robot vacuums from competing brands. Neato’s connected series of vacuums all offer WiFi and app connectivity, a feature iRobot originally reserved for their premium models.

Enter the 690, which is basically the same vacuum as the 650 except for 3 differences: Wi-Fi connectivity, a slightly upgraded Virtual Wall accessory, and a Li-Ion (instead of Ni-CD) battery.

These upgrades are nice to have, but still doesn’t address the main drawback of the 650: the rotating brushes. Without brushless rubber rollers, the Roomba 690 is just as bothersome to maintain, just like robot vacuums from competing brands.

Don’t fall for the Wi-Fi connectivity of the 690. I do not recommend this model because it is basically the same as the 650. Sure, the ability to schedule and start your Roomba remotely is nice, but in reality you will not be doing that on a regular basis. Robotic vacuums are meant to be set it and forget it devices, and adding Wi-Fi connectivity does not add that much value in our opinion.

Areas needing improvement:

  • Same as competing brands and Roomba 650: tedious maintenance when hair inevitably gets stuck in rotating brushes

Bottom Line:

  • If budget is your only concern, do not choose the Roomba 650 or 690. Go for a Roomba alternative instead. Just like the 650 and 690, Roomba competitors don’t have brushless rollers. They are also usually cheaper than Roombas.
  • If budget is your main concern but you also care about ease of maintenance, go one tier higher than the cheapest and choose the Roomba 860 instead.

Roomba 860

In short: “Basic Roomba with Brushless Rollers”

Update: iRobot has replaced the 860 with the WiFi-enabled 890. Since they are no longer officially selling the 860, it may be harder to find/more expensive. If you see that the 890 is cheaper, skip the 860. No reason to pay more for a model with less features.

Having gotten the 650 out of the way, let’s look at some REAL Roombas. (Sorry 650!) This is the new standard in budget robotic vacuums. If you don’t want to spend too much money and want a robot that just cleans without any extra bells and whistles, the 860 is most likely the best fit for you (check Amazon price now).

How is the 860 better than the 650? Brush-less rollers (matters more than you think)

In the world of vacuums, brush-less rollers are no doubt the best thing since sliced bread. I love this new design so much that I no longer recommend vacuums with traditional rolling brushes. The manufacturer calls them “tangle-free debris extractors”, which is more complicated sounding than it needs to be. They are really just two rubber rollers with protruding “feet” that beat and vibrate the floor as the Roomba moves around. The vibrations shake the dirt off the carpet and into the path of the vacuum.

Compared to the Roomba 650, this results in an equally clean floor and much easier maintenance. If you’ve ever tried to pull hair out of a traditional vacuum brush roller, you know how tedious the process can get.

With the 860’s rubber brush-less rollers, hair rarely gets stuck in the vacuum, and even when they do, pulling out the hair is a trivial task. Just pop out the rubber rollers, and the stuck hair can be easily pulled out.

My wife has shoulder length hair, and so much of it ends up on our floors. The hair eventually ends up stuck on the brushes of our upright vacuum. If I don’t clean the hair out every so often, it would make this terrible burning smell–something akin to a burnt hair and dust burrito. But tearing the hair out of the vacuum was so tedious, it used to be the chore I hated the most.

I hated it so much that I avoided vacuuming as much as I can unless the carpet was starting to look gross or we had a guest coming.

With the brushless Roombas, all the hair on the floor now ends up directly in the dust bin. We come home to a clean house and a dustbin full of hair and dust. Every time the Roomba vacuums, I look forward to seeing how much dust and hair it got this time. It is so satisfying to see all that hair and dust trapped in the bin.closeup of roomba 860 rubber rollers

The 860 includes a “Virtual Wall Barrier” accessory (used to be called Virtual Wall Halo), which is a beacon that you can position to block off access to certain areas. In Virtual Wall mode, the beacon emits a beam to block openings of up to 7 feet. In Barrier/Halo mode, the beacon emits a signal marking off a circle around the beacon instead of a beam. The signal tells the Roomba not to come near the beacon. This is useful for things you wouldn’t want the Roomba to knock over, such as pet water or food bowls.

Areas needing improvement

  • As good as the brushless rollers are, the 860 is still a budget entry compared to other models in the Roomba line.
  • The 860 does not have WiFi connectivity, so you can’t use the iRobot app with it.

Bottom line:

  • Good for pet and human hair. If you home layout is simple and price is the main concern, go with the 860.

Roomba 890

In short: “The 860 with wifi, good for those on a budget”

How is the Roomba 890 Different from the 860? – Wifi Connectivity

The Roomba 890 is iRobot’s answer to its main competitor Neato’s internet-connected BotVacs. To put it simply, the 890 is just the 860 with WiFi connectivity added.

With Wi-Fi comes all the capabilities of the iRobot Home app. For example, the app records how many square feet the Roomba vacuumed, the number of times it has cleaned in total, and the amount of time it spent vacuuming in total.

Neato’s latest line of vacuums all come equipped with WiFi, so iRobot responded by adding WiFi to its budget and mid-tier vacuum lines also.

There are two main differences between the 860 and 890. The 890 has (1) WiFi connectivity and (2) an upgraded battery (now Li-Ion).

Areas needing improvement:

  • The 890 doesn’t have cameras and sensors to vacuum the house as efficiently as the 900 series Roombas.
  • The 890 is not able to recharge and resume, meaning that if you have a large home, it might be be able to completely cover the entire floor before the battery runs out.

Bottom Line:

  • Although this model seems like a good middle ground between the high end and budget Roombas, the 890 is stuck in no-man’s land in terms of price and features. Either go up to the 960 for better features or go down to the 860 to save money without making too much compromise.

Roomba e5

In Short: “A slightly updated Roomba in the economy class”

How is the Roomba e5 Better Than the Roomba 890? – Larger Battery, Larger (Washable) Collection Bin

Released alongside the i7, the Roomba e5 is meant to be the ‘budget’ Roomba for the next generation. While it is visually similar to the 890 and performs in a near identical manner, the e5 does have some improvements.

The e5 boasts a larger collection bin than the 890 and you can even wash it out in the sink. The washable collection bin helps keep all parts of your robot clean, even those hard to reach spots like the inside of the dustbin.

You will also notice that the e5 has a larger and longer lasting battery than the previous economy model. The potential runtime of the Roomba e5 is 15 minutes longer than the 75 minute expected runtime of the Roomba 890.

Thanks in part to a large 3300mAh lithium-ion battery pack, the e5 has a more efficient cleaning pattern and the sensors work at a more responsive rate.

Areas Needing Improvement

There is no reason, for the price, that the e5 couldn’t be equipped with the camera for better navigation or mapping abilities.

The recharge and resume feature has been well established since the 800 series. While it needs the ability to map for it to work, it would still be nice to know that your floors are completely clean by the time you get home.

Bottom Line

In terms of actual everyday use, there is not much different between the 890 and the e5. Pick up whichever one is on sale if you are trying to decided between these two.

 


Roomba 960

In short: “The best Roomba for most households, great price to value ratio.”

How is the Roomba 960 Better than the e5? – Visual Mapping + Recharge and Resume

The Roomba 960 is where the upgrades start to get really good. Although it was released way back in August 2016, the 960 is still one of the best vacuums in the Roomba lineup.  (Check Amazon for current price and any available discounts)

It was one of the first Wi-Fi enabled Roombas. You can set the Roomba’s cleaning schedule directly from the phone, and also change some preferences regarding how you’d like the Roomba to clean. The app also has reminders to tell you when the dust bin needs emptying and when the Roomba requires maintenance.

More importantly, the 960 is equipped with visual sensors. Other than the i7/i7+, the 960 and 980 are the only Roombas currently on the market to have them. These sensors use your furniture and walls as landmarks to create an internal map of your house.

Previous Roombas always use a pseudo-random pattern to vacuum, resulting in the haphazard cleaning pattern that puzzle most Roomba owners. With visual mapping, the 960 can finally vacuum in straight lines.

Vacuuming in a pseudo-random pattern is fine and actually produces great results after multiple passes, but it is just so mesmerizing to watch the 960 vacuum an area lane by lane. If you have any hint of OCD, the lines traced by the Roomba 960 will satisfy that inner compulsion.

Finally, the 960 is able to automatically recharge when low on battery and resume vacuuming where it left off. Once again, the 960 and 980 are the only current Roombas able to do so, thanks to their visual mapping technology. This means that no matter how big your house is, the Roomba can clean an entire level when you are away, recharging as necessary.

Areas needing improvement:

It’d be nice to have carpet boost like the 980, but considering the price difference, this is our favorite Roomba.

Bottom Line:

This is the best Roomba model to pick up if you want the best combination of price and features. The technology on the 960 are not just marketing buzzwords but actually result in a great user experience. Our top Roomba pick.

Roomba 980

In short: “Great for carpet but too expensive”

roomba i7 with smart phone

How is the Roomba 980 better than the 960? – Higher Battery Capacity and Carpet Boost

The 980 is very similar to the 960 in terms of overall features, with the following differences:

The first difference is that it comes with two Virtual Wall Barrier accessories instead of just one. The Virtual Wall Barriers are nice to have, but one may already be enough for your household. You can also purchase them separately if you find that you need more. One or two should be enough for most households, though.

The second difference is that the 980 sports a better battery that gives it a continuous run time of 120 minutes instead of the 960’s 75 minutes. Given that both models are able to recharge and resume though, a bigger battery doesn’t mean too much to me. If I won’t be home when the Roomba is cleaning, who cares if it takes a break after 75 minutes to recharge?

The third difference is that the 980 sports a newer generation motor that the manufacturer claims to be 10x the suction power of the most basic Roomba.

The last difference is important for households with mostly carpet. The 980 is equipped with an additional “Carpet Boost” sensor that can tell whether it’s on carpet or a hard surfaces. When it detects carpet or area rugs, the motor is revved up to increase suction. The idea is that dirt is harder to vacuum off of carpet, so the increased suction will help compensate.

We compare the 960 and 980 in detail here.

Areas needing improvement

Although it is almost the perfect Roomba, the price is too high, even for its advanced features..

Bottom Line:

With the release of the i7, the Roomba 980 is stuck in a very awkward position. The i7 is equal or better in every way and it is cheaper. Skip this one and go one model down to the 960 (for price) or one level up to the i7 (for features).

Roomba i7

roomba i7 with smart phone

In Short: “Newest technology without hefty price tag of i7+”

How is the Roomba i7 Better Than the Roomba 980?

On the inside, the motor has been repositioned to take full advantage of the high powered suction with carpet boost. This positions allows it to pick up more debris.

The dustbin is the largest yet for Roomba. The 0.7L capacity collection tank is only found on the i7, i7+ and the e5 models. Regardless of how often you vacuum, a bigger bin means fewer bin-emptying’s after a cleaning session.

The processing units in the i7 are more powerful. This was done, in part, to aid the new navigation software. The i7 and i7+ are the only two models to use the iAdapt 3.0 tech, which means:

  • The robot will detect areas of your home that constantly need a deeper cleaning and pin those areas on its internal map.
  • The i7 can now map and remember up to 10 different floor plans at the same time – this means it’ll know whether it’s upstairs or downstairs in your house after a couple runs.
  • Moving furniture no longer means the robots have to remap the entire floor plan. The i7 will now adjust the locations of obstacles on the fly.
  • Dirt detection has improved to allow the robot to make tiny adjustments in its cleaning angle instead of having to loop around.

You might’ve heard of their new ability “Imprint Smart Mapping”. What this means is:

  • You can label your rooms (kitchen, living room, bedroom, etc) and specify a cleaning on specific rooms only.
  • You can use voice commands with Amazon/Google devices to say things like “Alexa, tell Roomba to clean the bedroom.” the robot will run off to clean just that room.

At this time only a single room can be cleaned using voice commands. If Smart Mapping is enabled, though, you can use the regular voice command to clean the entire home and the robot will only clean the rooms enabled in the map.

Even though the i7 is technically better, emptying the dustbin isn’t a horrible chore. Paying a lot more money for the i7+ is a bad idea. Of course, if you decide later that you want the i7+ you can always make the purchase and upgrade at any time.

Areas Needing Improvement

The voice commands for multiple room cleaning aren’t available yet, but they should be. Using voice commands to only clean one room at a time is nice, until you need two rooms cleaned.

Bottom Line:

The Roomba 980 has been unseated, this is our new best overall pick. If you have the budget for it, the i7 is the easy choice. It’s better than the 980 in every way and it’s cheaper. Even if you wish to upgrade later, you can always turn it into an i7+ by buying the dock separately.

> See the i7 on Amazon <


Roomba i7+

Roomba i7+ docked on its charging and auto-emptying base

In Short: “Upgraded i7 with the Ability to Empty Itself”

How is the Roomba i7+ Better Than the Roomba i7?

Difference 1: the large docking station allows it to self-empty. The i7+ has a special charging station called the “Clean Base” that allows it to empty itself.

For every other Roomba on the market, the dock has not changed much–they are low profile and don’t take up much floor space.

For the i7+, the Clean Base automatically sucks everything out of the dust bin every time it docks.

The process is loud, though. You won’t be able to muffle it and will definitely know when it is being used.  If you’re a veteran Roomba owner, you know what the Roomba sounds like while it vacuums. The Clean Base is different, when the base turns on to suck the dirt out of the Roomba, it sounds like a full sized corded upright vacuum.

Granted, this noise only lasts a couple seconds. It is definitely noticeable though, even when you’re not in the same room. Unless you live in a mansion, you’ll be able to hear the robot empty itself no matter where you are in the house. This may be satisfying if you like to hear that your robot is indeed doing its job.

One thing we do have to give iRobot credit for is the design of the Clean Base, even though it looks HUGE, it doesn’t take up any more footprint than the Roomba itself. With the robot docked, the only additional space the Clean Base takes up is the 18.5 inches of “airspace” above the Roomba.

Difference 2: the dustbin is slightly different to accommodate self-emptying. While the size is the same as the i7, the i7+ bin has an opening with a rubber flap to allow the Clean Base to suck out the contents. The flap prevents the contents from escaping back to your floor. It is this seal that the Clean Base recognizes and begins suctioning out the contents.

Besides the above two differences, the robots themselves are identical. This means you can upgrade from the i7 to the i7+ if you change your mind later.

For this reason, I only recommend the i7+ if you absolutely hate emptying the dust bin. Although the i7+ is the best of the best, the i7 does everything just as well (minus the self-emptying). The price premium is quite high, and you can always upgrade later (but not downgrade)!

Areas Needing Improvement

  1. The Clean Base is very loud.
  2. Using disposable vacuum bags seems like a step backwards in this day and age. Not to mention it’s an added cost. Perhaps an optional reusable large dust bin may help. It’s really not that much work to empty a dust bin.

Bottom Line:

For people who really hate emptying the dust bin and people with severe dust allergies, the Roomba i7+ makes sense. For everyone else, the i7 is a much cheaper option.

Frequently Asked Questions about Roombas

Is it true that you can’t move a Roomba from one floor to another in a multi-story home because it can only memorize one floor?

In terms of mapping ability, there are 3 categories of Roombas. The Roombas in all 3 categories can be moved from one floor to another without issue, for different reasons.

Roomba models 6xx and 8xx do not have any mapping ability, and therefore do not ever “learn” your home layout. This means it doesn’t matter if you move them from one floor to another.

Roomba models 960 and 980 do have mapping built-in. But every time they perform a new cleaning cycle, they will make a new map of the layout. In other words, these Roombas do not save or store the mapped out areas (at least the current software does not), so moving it to a different story of the house would not confuse it.

Roomba models i7 and i7+ also have mapping built in. It is able to memorize up to 10 floor plans. When you move it from one floor to another, it will use its internal maps to determine where it is located and clean accordingly.

Does the Roomba resume cleaning where it left off when the battery is low?

Yes, iRobot calls this feature “recharge and resume” and it is available on models starting with the number “9” and the i7 and i7+.

When the robot detects that it is running low on battery, it will return to its dock to charge. After charging, it will go back to where it left off and finish cleaning the entire floor.

Why do you recommend the “brushless” models so much?

Robot vacuums are supposed to make your life easier.  It kind of defeats the purpose of getting a Roomba if half the hair on your floor ends up tangled in the rolling brushes. If you’ve tried to manually extract stuck hair from a vacuum bristle, you know what a pain it can be.

The brushless models avoids this problem. When hair does get trapped on these rollers, extracting the hair is easy.

Which Roombas are brushless?

Any Roomba with model numbers that begin in 8 or 9.

Roomba e5, i7 and i7+.

Is a home Wi-Fi network required for WiFi-capable Roombas? Do I have to download the iRobot app?

No, you do not have to have a home Wi-Fi network to use the internet connected Roombas.

Without a home network (and therefore the ability to use the app), the Roombas will still vacuum (you can just hit the physical Clean button), but you would miss out on the functions that require the iRobot Home app such as scheduling and changing cleaning preferences.

Since the internet connectivity is why some of these robots cost more, I’d recommend going with one of the more basic models if you anticipate not ever having WiFi in your home.

Are any of the older Roombas compatible with the self-emptying Clean Base?

Unfortunately, only the i7 can be upgraded to the i7+ by purchasing the Clean Base addon. The addon includes a special dust bin that is required to interface with the Clean Base. Older models are not compatible. This effectively turns the i7 into an i7+, which is the only self-emptying robot vacuum available today.

So if I have a multi-room layout in my home, should I not get an 800 series Roomba?

It depends on how much human interaction you would want in your cleaning.

If you are on a budget and don’t mind manually picking up the Roomba and placing it in the room you want it to vacuum, any of the 800 series is fine.

But if you want to take a more “hands-off” approach, you will probably be better off with a 960. This robot is able to cover every inch of the floor in a logical and efficient manner.

For the ultimate “set it and forget it” vacuum, the Roomba i7+ has the features of the 900 series in addition to the ability to empty itself.

Will the Roomba climb over my transition molding or other obstacles?

Yes, most likely it will. Unless the height difference between two areas is very significant (i.e. over 3/4″), all current Roomba models should climb over the obstacle no problem with their 3 inch wheels.

How loud are Roombas while they vacuum?

Since they use similar motors and suction technology, the noise levels do not vary significantly between all Roomba models. The noise level depends on the type of surface it is vacuuming.

On hardwood floors, the Roombas measure about 65 to 70 decibels. They are quieter on carpet, measuring about 60 db. For comparison, a normal conversation is also about 60 db.

Although these are quiet by full size vacuum standards, they are not quiet enough for you to sleep while they clean.

How Good are Roombas at Cleaning Corners?

All Roombas have a spinning sidebrush that sweeps dirt into the suction path. In a regular room (where the corners are at 90 degrees angles) there will be a small triangle measuring about 1.5 inches in length where the side brush can’t reach. This means that those corners will never be vacuumed by the Roomba.

In practical terms, this has not caused any problems though, meaning that the corners of my house are clean and I don’t see any dust buildup in the shape of a triangle in the corners.

So the 900 series and the i7 can clean an entire level, but what about the 800 series?

iRobot only guarantees the 960 and 980 can clean an entire level because those are the only models with onboard cameras and visual navigation. They map the floor as they vacuum and do so in more-or-less straight lines. They have also been lab tested to cover up to 2,000 sq. ft.

The 800 series, on the other hand, cleans randomly. It will not clean an entire level if the layout is split into multiple rooms with doors and hallways. Most American homes probably fall into this type of layout.

My home has multiple rooms, would a 800 Roomba clean every single one of those rooms every day?

It would run for about 60 minutes, then return to the charging station. How far it gets is heavily dependent on the layout of your home.

Let’s say you have 1,500 sq ft split into a living room, two bedrooms, a bathroom, and a kitchen. You place the docking station and Roomba 860 in the living room and set its schedule to start cleaning every day at 10am. Would it clean every room?

In this layout, the 860 would probably not get to it all. This is because it uses a semi random pattern in determining where to go next. The area where the Roomba starts will always be vacuumed, but where the Roomba goes next is random.

The navigation logic of the 800 series uses the feedback from the sensors to make 60 decisions per second on where it goes, dictating 40 robotic moves.

What this translates to is not as impressive in real life. If it finds itself near an open doorway, it will probably move into it most of the time.

But without the charge and resume feature of the 900 series, it will likely not cover every room. It’ll vacuum as much as it can (which rooms it picks is up to chance), and return to the home base when it runs out of juice.

On the other hand, if you live in a giant studio that is just in the shape of a rectangle 1,500 sq ft large, the 860 would most likely vacuum all of it in one go, even with the nature of its random navigation.

Which Roomba Model is Best for these Specific Situations?

Hair and Pets

cleaning hair out of roomba

If you have pets or a family member with long hair, pick anything but the 600 series vacuums. Not only are all the other models equipped with HEPA filters, they are a breeze to clean. With the 6XX vacuums, you will want to start pulling out your own hair out while trying to extract the hair that’s stuck in the vacuum itself.

For a more in-depth article, read our guide to choosing the best roomba for pet hair.

Flooring – Hard floor surface (such as hardwood, tile, marble, etc)

All the Roombas perform similarly on hard surfaces. Even though the different models claim 5x or 10x suction on their boxes, they all seem to pick up dirt equally well on a hard floor, even the poor 650 I keep bashing.

Flooring – Carpet

The best Roomba model for carpets are the Roomba i7 and the 980, because they have the strongest suction power of all the Roombas.

The 980 is older and does not have as many features as the i7 (e.g. “imprint smart mapping” which lets you pick specific rooms for cleaning). The two vacuums are similarly priced, so unless the 980 is significantly discounted, I would pick the i7 over the 980.

In practice, any of the Roombas in this guide will do a good job, but if you have high pile carpet and want the best of the best, the i7/i7+ is your best best.

Home Layout – Studio or One Bedroom

When it comes to simple layouts, any Roomba in this guide will do. Models starting with a “6”, “8”, or “e” use a pseudo-random cleaning pattern, zigzagging around your home until it covers every inch. The rest (namely the 960, 980, i7, and i7+) are more sophisticated and use a combination of sensors and cameras to map your house. They vacuum big open areas in straight lines, like a human would.

Either method will work, so the cheaper models are good enough.

Home Layout – 2+ Bedrooms

The best Roombas for households with multiple bedrooms are the 960, i7, and i7+. There are two reasons for this.

The first reason is that they are much more logical and efficient in navigating your home. The sensors and cameras allow these Roombas to know where they are and where they should go next (vs the random zigzagging of lower models).

The second reason is the ability of these models to recharge and resume vacuuming when they are low on battery. If you have a large home, this allows them to clean the entire floor of your home. The older Roomba models will just return to its dock when the battery runs low and not know where it has or hasn’t vacuumed. This will result in certain areas not getting cleaned if you have a particularly large or complex layout.

Home Layout – Multiple Stories

Unfortunately, there is no Roomba that can vacuum two levels in one go. The ability to climb stairs is just too complex for consumer robots with current technology. Some owners have suggested stationing your older vacuums on your upper levels when you get a new one.

Not everyone can afford two robot vacuums though. So until then, you can just pick it up and set it down on whichever level you’d like to be cleaned and press the big “Clean” button in the middle. The Roomba doesn’t care where it is placed, and will vacuum the area in its entirety.
