Which Roomba would be the best for you? Editor’s choice:
Not the best on hard floors but is capable of agitating dust and dirt on carpets.
Works just fine on carpets too but on hard floor the Roomba e5 is a beast. Best budget option if you have pets.
The best budget robot if you want mapping and don’t have thick carpets. Ideal for pet hair and low-pile carpet flooring.
Thanks to the recent price drop, the Roomba i7+ is the best value. It performs great on hard floors and carpets, handles pet hair and has many smart features such as room cleaning, keep-out zones, etc. The Roomba i7+ is ideal for multi-story houses because of multimap support.
The Roomba s9+ is recommended for homes with minimum furniture and mostly carpeted surfaces.
Cliff & Anti-collision sensors
The cliff and anti-collision sensors prevent bumping into things and falling from stairs. The iRobot cleaners have cliff and anti-collision sensors as well as an auto-recharging function which automatically makes the robot returning to the dock when the battery runs out of energy.
What is Spot Clean Mode
In Spot Clean, the robot moves by spiraling about 3 ft (1 m) in diameter, ensuring intense coverage (supported by all Roombas).
Dirt Detect Series 1 vs. Series 2 with Persistent Pass
Patented Dirt Detect sensors alert Roomba to work harder on concentrated areas of dirt, such as high-traffic zones of your home. The sensors recognize problematic areas and boost up suction power to provide deeper cleaning.
Series 1 uses acoustic sensors to detect small particles whereas Series 2 uses optical and acoustic sensors. When the robot finds dirt in the first case it will make several passes until the area is clean, while the models with Series 2 will automatically do concentrated cleaning (similar to spot cleaning).
What is Full Bin Indicator
The newest Roombas have a Full Bin Indicator that alerts when the bin is full. The Roomba 960 and 980 models have two options: "Finish Job" and "Pause immediately," that can be managed via the iRobot Home app. The first one ends cleaning immediately while the second feature stops cleaning temporarily. Once you empty the bin, the Roomba will continue.
The Roomba i7+ and s9+ automatically return to the charging dock when the container gets full, empty themselves, and resume cleaning.
You can program a Roomba (except for the 614 model) to work at a specific time up to 7 times per week by using a remote controller or the iHome app.
The new Roomba i7+ and s9+ can be also ordered to clean a particular room or two at a specific time if needed.
What technology does the Roomba use to navigate the robots? iAdapt Cleaning Technology & Navigation
iAdapt Navigation is a set of sensors that help the robot cleaner to move around without falling using a random navigation pattern. Roomba prevents hitting walls and other solid barriers by using Light-Touch bumper technology.
However, the Roomba 960 and Roomba 980 use the upgraded version of iAdapt, iAdapt 2.0. iRobot improved the navigation pattern and added the Visual Localization, a system that uses a camera sensor for mapping. The Roomba 960 and 980 move in straight lines.
The newest Roomba i7/s9+ use an advanced navigation system - iAdapt 3.0. These models are more sensitive to obstacles and are more efficient.
What is the AeroForce Cleaning System?
AeroForce cleaning system: dual counter-rotating tangle-free brushes grab dirt and debris from carpets and hard floors. The airflow accelerator boosts suction power to catch dust, debris, and allergens, with the dual counter-rotating tangle-free brushes help, transfers the dirt right into the dustbin. A side brush helps to catch the debris on the corners and along the walls.
The latest models use a more powerful vacuuming system with more suction. (The Roomba 980, i7+, and s9+ recognize carpets and by boosting suction provide deeper cleaning). The Anti-tangle system will not allow the robot to get stuck between cords, carpet fringe, or tassels. If it does, the system stops the side and main brushes of the vacuum and tries to escape.
Edge Cleaning Mode
The 900s, i7+, and s9+ models have Edge Cleaning Mode. While the older generations used a side brush, the newest ones go along the walls after they finish the job on the floor. This feature is always on default, but if you want your Roomba to end the job quicker, you can switch it off on your smartphone.
Recharge and Resume
Once the battery runs out of energy, a Roomba returns to the charging dock. After powering up, the robot resumes cleaning from the spot it left off to finish the job. The models with mapping resume cleaning.
Rotating Double Brushes
Two brushes located on the bottom rotate in the opposite direction to grab and break down dirt and debris. This technology was upgraded in the 800, 900 series, i7, e5, and s9 models. These are equipped with silicone rollers that are ideal for pet hair and almost don’t require maintenance.
Why buying a Roomba with the silicone brushes
If you are not tight on your budget, you might look at the latest robot vacuum cleaner. I have had the iLIFE V7S myself and faced the issue of hair wrapping around the brush after every cleaning. My wife has long hair, which means the brush needed to be cleaned after every session. By contrast, rubber rollers are tangle-free and are much easier to maintain.
How to control a Roomba?
There are three modes available: app, a remote controller, and voice commands. The robot vacuum cleaners that support Wi-Fi can also be controlled via the iRobot HOME app and are compatible with Amazon Alexa and Google Home so if you have any of these you can also control your Roomba via voice. The first models work with an included remote controller.
The latest Roomba i7 and s9 can be ordered (with Alexa and Google Home) to clean a particular room via using voice.
What you can do with the iRobot Home app
The app helps you control your Roomba, set a cleaning schedule directly from the phone, or switch between cleaning modes. The app also alerts you when the dust bin is full.
If you are a happy owner of the latest robots that have a mapping feature, you can see cleaning history at the end.
Needless to say that you also can start and stop your robot anytime just using your mobile device.
The Roomba i7+ and s9+ are different. When the map is created, you can divide it into separate rooms, so the robot knows where each room is located. If you want the Roomba to clean a kitchen, you can choose the kitchen in the app or simply say: «Roomba, clean the kitchen» (if you have an Alexa-enabled device or Google Home) and let the vacuum do the job. Also, those models store up to 10 different maps, and you can interact with them by setting keep out zones, name each room, or choose which one you want to be cleaned.
Dual Virtual Wall Barrier
The Dual Virtual Wall Barrier is another device that helps to keep the Roomba away off some areas. You need to place it somewhere in the room, and the Roomba won't cross it.
Keep Out Zones
iRobot is the first manufacturer that introduced digital restricted areas on camera-guided robots. It is only presented in the Roomba i7+ and s9+. In the map, you can set zones that you don’t want the robot to clean.
Clean & Schedule By Room
The Roomba i7+ and s9+ have a new option that allows cleaning a separate room or two instead of the whole house. Some rooms get dirtier sooner than others like a kitchen or living room, so there are times where you need to clean only one room. By simply tapping on the map, you can make the Roomba clean a certain room and schedule the robot to clean the room at a specific time.
These are the first models that are compatible with Amazon Alexa or Google Home in a way that allows them to command to work within a particular room. By saying: «Roomba, clean the living room,» you let the cleaner know what to do.
Clean Base Automatic Dirt Disposal
The latest Roombas come with the self-cleaning base. It has a disposable bag inside that holds up to 30 Roombas bins. When the robot’s container gets full, or it has finished the job, the Roomba returns to the base where the dirt gets sucked up into the bag. The base sets you free from emptying the dustbin for about a month depending on usage.
Roomba 600 Series
These are one of the oldest models in the family and the most baseline. There is no mapping nor smart navigation, just random-bouncing robots that are good for hard floors and thin carpets. Each has dirt detect technology and similar specifications, the same goes for cleaning abilities.
The Roomba 614 - Super Basic
The Roomba 614 is a very basic budget robot vacuum cleaner. It is the only model that doesn't have a scheduling feature, which is quite disappointing.
We do not recommend this model because of the high price for what it offers.
To buy or not to buy the Roomba 614
With its price and cleaning performance, we'd suggest considering buying one of the newest Roborock E4 that has the options the Roomba 614 is missing or go with the Roomba 690.
The Roomba 690 - Affordable Robot with a Virtual Wall Barrier
The Roomba 690 is the first robot vacuum in our list that supports Amazon Alexa and Google Assistant and can be managed by the iRobot Home app. The 690 comes with Virtual Wall accessory which makes the Roomba 690 different from the Roomba 614.
Still the same cleaning brushes that are not too easy to maintain.
What is the Roomba 690 good for?
- Small homes. Because of random navigation, the Roomba 690 would be suitable for small places.
- Homes with a mixed surface. The robot does a good job on thin carpets and bare flooring and not as good on thicker carpets and not suitable for homes with a mostly carpeted surface.
Verdict: If you are ready for bristled brushes, which means you need to get rid of tangled hair after every session, have a look at the Roomba 690.
Update November 2018 What you can get instead of the Roomba 690 for under $300? Take a look at the top 5 best Roomba 690 alternatives.
Roomba 614 vs. 640 vs. 675 vs. 690
There are four models available to buy and it can be challenging to distinguish them and decide which one is right for you. Keeping in mind that all of them have the same cleaning rollers and cleaning mechanism, there is not that much of a difference between the robots.
The Roomba 640 has a longer runtime compared to the Roomba 614 (90 minutes vs. 60 minutes). Despite the design, these are very similar robots that do not have wifi and all the following features such as app connectivity and integration with smart home.
The Roomba 675 has the same cleaning mechanics as the 640 model does but is Wi-Fi-enabled. That means you can schedule the robot and control it from your phone. It is also compatible with Amazon Alexa and Google Home so if you have one of these, you can make it start or stop with your voice. The Roomba 675 does not have a dual virtual wall barrier in the box but it is compatible with one so you can buy it separately if you already have the 675 model.
When comparing the Roomba 675 with 690, you might not see many things that make these robots different. The Roomba 690 coming with a dual virtual wall barrier and is a bit more expensive. Other than that, there are no more differences between the two.
Bottom Line: we would not suggest getting the Roomba 614 or 640 because of no visible reasons for that except for the included Wall Barrier with the 675 and 690 cleaners.
- Roomba 675 is suitable for small spaces and uncluttered homes so it will not get itself trapped in some areas and you don’t have to babysit it.
- Roomba 690 is better for slightly bigger homes where you can block it from going to certain places with the virtual wall barrier.
Roomba 800 Series
These are upgraded versions of the previous Roomba. These robots come equipped with tangle-free rollers that are designed to resist hair tangling and are ideal for pets. None of these robots have a camera to map the room and thus they do not remember your floor layout. Because of the silicone rollers, the 800 Series is not suitable for carpet cleaning. It does not have enough suction power and can’t efficiently agitate debris on carpets.
Roomba 890 - App-Based Robot With Tangle-Free Rollers
What is the Roomba 890 good for?
- Small homes. Because of short battery life, the Roomba 890 is not suitable for average and big homes.
- Pet hair only if you don’t have carpets. The silicone rollers are the best at handling pet hair picking it up on bare flooring but don’t do well on carpets.
- Homes with bare floors.
Roomba 880 vs. 890 vs. 891
Despite the price and design, there are the same cleaning abilities and features between the models except for a few changes.
The Roomba 880 does not have Wi-Fi and can not be controlled by a smartphone neither by Google Home or Amazon Alexa. It also has a different type of battery (Nickel Metal Hydride battery) while others have the newer Lithium-Ion.
The last thing would be two Virtual Wall Lighthouses (VWL) the Roomba 880 comes with. These things can be set up to prevent the vacuum from leaving an area (or entering one) until the current area is clean. The robot vacuum will send a signal to the lighthouse alerting it that the area is clean and the lighthouse will disable the barrier, allowing the robot to pass to the next area. The VWL can also be set to block the robot from entering a set area.
The Roomba 890 has a Li-Ion battery and can be connected to the iHome app and also be integrated with Amazon Alexa and Google Home.
Another difference is the dual virtual wall barrier the Roomba 890 has in the box. Unlike the lighthouses, though, the wall barriers do not have lighthouse mode, it can only block the robot from entering an area or create a radius barrier.
The Roomba 891 has absolutely the same features and specifications only does not include the dual virtual wall barrier in the box.
- Roomba 880 has a different battery type and does not have Wi-Fi;
- Roomba 890 comes with two Virtual Wall Lighthouses while the 890 has the Virtual Wall Barrier;
- Roomba 891 does not include the virtual wall barrier.
To conclude: The Roomba 800 Series is good for hard floors and pet owners but it has the same price as the more powerful and advanced Roomba e5 does. If you catch one of the Roomba 800 models with a good discount which happens occasionally, that would be a good buy but for the current price, we would suggest getting the Roomba e5.
Roomba 900 Series
The Roomba 900 Series is the first line that has a camera onboard and is capable of remembering floor layout. Also, these robots support resumption which makes them suitable for bigger homes.
The Roomba 960 has advanced navigation thanks to the camera that creates a map of the cleaning area helping the robot to know where to clean.
The robot has a built-in sensor that alerts when the bin needs to be emptied. Because of the silicone rollers, this machine is ideal for pet hair.
What is the Roomba 960 good for?
- With 75 minutes of battery life and resuming the Roomba 960 is suitable for small and average homes.
- Homes with no carpets or mixed surface.
- Pet owners if there are no thick carpets. The silicone rollers do a great job at picking up pet hair but the suction is not enough to provide deep cleaning on carpets.
- Cluttered homes. With mapping, the Roomba 960 finds its way around better than models with random navigation.
Why you should buy the Roomba 960
Considering the price, the Roomba 960 is one of our favorite robot vacuums to get in 2020, since it has everything you need if you want the best combination of price and features. Keep in mind; the Roomba 960 would not provide deep cleaning on thicker carpets and is better for low-pile carpets and hard floors. The robot is suitable for small homes.
The same as the Roomba 960, Roomba 980 is equipped with a camera to build a map of the room and also has an advanced Gen 3 motor inside that gives more suction power on high settings or when the robot detects carpets. Once it identifies carpet, it boosts suction providing deeper cleaning.
What is the Roomba 980 good for?
- Homes with a mixed surface. Even though the Roomba 980 has stronger suction than the 960 series, it would not vacuum high-pile carpets.
- Pet owners. With brushless rollers, the Roomba 980 is good for pet and long human hair.
- Thanks to 120 minutes of battery life, the machine covers a bigger area on one charge.
- The camera helps to navigate in cluttered homes.
Verdict: the Roomba 980 was a good robot vacuum to get in 2015 when it was released but it’s a bit expensive now. Yes, it has silicone rollers, strong suction, and camera on the top but for the same price, there is a new Roomba i7 that has more smart features, advanced mapping, and better silicone rollers. In addition, you can buy a self-emptying charging base in the future which the Roomba 980 does not support.
Roomba 960 vs. 980 vs. 985
The Roomba 960 has a shorter battery life compared to the Roomba 980 (75 min vs. 120 min). It also has weaker suction. Along with weaker suction, the Roomba 960 does not recognize the carpeted surface.
The Roomba 980 has Carpet Boost which increases suction power once the sensors recognize carpets.
The Roomba 980 and 985 are basically the same robots, the differences come in what is included in the box and the cost. The Roomba 985 has a charging dock & cord, extra filter, one dual virtual wall barrier, and manual. The Roomba 980 includes the same things + in addition an extra side brush and two dual virtual wall barriers.
The main differences:
- Roomba 960 has shorter battery life. It also has weaker suction and is not able to recognize carpets;
- Roomba 980 recognizes carpets and is more powerful (compared to the 960);
- Roomba 985 is the same as the Roomba 980 only has a different accessory pack and costs less.
The Roomba 960 is good for smaller homes with pets and low-pile carpets/hard floors.
Roomba e Series
Roomba e Series has a few modifications: Roomba e5 (5150 and 5134) and e6. These are upgraded versions of the 800s but are more powerful and suitable for medium-pile carpets. The Roomba e5 does not remember your floor plan; it is equipped with advanced tangle-free rollers the same type as the Roomba i7 has.
In our opinion, the Roomba e5 is the most underrated robot in the model line. This model provides the best cleaning performance among other Roombas that do not have mapping. In short, it has the same platform as the Roomba i7 only with no premium features.
The Roomba e5 is the best model in the line among others with random navigation
What is the difference between the Roomba e5 and Roomba 890?
Unlike the Roomba 890 that is also equipped with silicone rollers, the Roomba e5 is equipped with advanced silicone rollers that provide a better pick up. Also, the newer model has a washable dustbin where the Roomba 890 does not and longer battery life (90 min vs. 60 min). The Roomba 890 comes with virtual wall barriers, the e5 does not have them.
What the Roomba e5 good for?
- Homes with low-pile and medium-pile carpets.
- Hard flooring.
- Pet owners because of the advanced brushless rollers.
- Small and average homes.
Roomba e5 vs. e6
Despite the color options, there is not much of a difference between the two. The Roomba e6 comes with more accessories such as an extra filter and two virtual wall barriers.
The Roomba e6 is only available at select retailers and has a retail price that is less than the listed price of the Roomba e5.
The manufacturer says: «the e6 has dirt detect 2 (Optical and Acoustic sensor for detecting dirt and debris) where the e5 has Dirt Detect 1 (Acoustic sensor)».
Roomba e5 vs. Roomba 890
The Roomba e5 has longer battery life but lacks the virtual wall barrier. The e5 is also equipped with the advanced silicone rollers the latest Roomba i7 has.
Why do you need to buy the Roomba e5?
The Roomba e5 has a $400 price tag. The Roomba 890 costs the same it has shorter battery life. The robot is ideal for pet owners, small to average households with carpets or bare flooring.
Roomba i7/Roomba i7+
The iRobot Roomba i7 was released at the end of 2018. It is one of the most expensive robot vacuums on the market and one of the most efficient robot vacuums from iRobot. This model is very similar to the Roomba 980 but has a few innovations such as advanced brushless rollers, a quieter motor, improved navigation technology iAdapt 3.0, selected room cleaning, washable dustbin, etc.
Roomba i7 vs. i7+
The Roomba i7+ comes with a self-emptying dock station that automatically empties the robot’s bin each time it docks or whenever its container is full and is designed to hold 30 robot bins of dirt and debris so you can forget about vacuuming for weeks at a time. Alternatively, you can buy the self-emptying dock separately later. Other than the included auto-emptying bin, there is no difference between the two.
Keep the Roomba i7+ out of certain areas by using the new «Keep Out Zones» feature
With the Roomba i7, you can divide a created map into zones, name each to make the robot clean in a particular room further. The i7 can remember up to 10 floors layouts, which is a useful feature for multi-floor houses. The new feature called «keep out zones» allows you to set restricted areas in the app. iRobot is the first company that has this feature in camera-based robot cleaners.
The Roomba i7+ stores up to 10 floor plans
The Roomba i7 has a new feature that allows cleaning a certain room or two. When the map is created, you can divide it into separate rooms and name each to be able to run the robot within one or more rooms.
Say «Roomba, clean the kitchen» to make the robot work within the kitchen only
What/who is the Roomba i7+ best for?
- Small and average homes.
- Cluttered homes. Because of mapping and digital virtual walls, the Roomba i7+ is more accurate to navigate around.
- Homes with many rooms.
- Alexa and Google Home owners. Because of more voice commands, the Roomba i7+ is useful in terms of controlling it by voice.
- Pet owners. Because of the full dustbin indicator, the Roomba i7+ automatically returns to the dock to empty itself once the dustbin gets full which happens often if you have pets.
- Parents and busy people. Since the Roomba i7+ empties itself, it is an ideal choice for those who don’t have time for chores, even not going to empty the bin after every cleaning.
- Suitable for both: homes with carpets and bare floors.
- Multilevel houses because of storing up to 10 different maps in memory.
Is the Roomba i7 worth buying? The Roomba i7+ is pricey but worth every penny. It is suitable for small and medium homes because of 75 minutes of battery life. Thanks to carpet identification, good climbing ability (0.79 in / 20 mm), and strong suction, the robot is perfect for homes with low and medium-pile carpets. Because of the newest charging base and brushless rollers, you don’t have to spend time maintaining the machine, it takes a few seconds to clean the rollers and empty the disposable bag of the base about once a month. Also, if you own a multiple-level house, the Roomba i7+ would be ideal since it stores up to 10 different floor plans and knows where it is if being manually placed upstairs.
Roomba i7 vs. 980: what has been improved?
- Multimapping. The i7 stores up to 10 different floor plans and is suitable for multi-story houses;
- Now it can recognize rooms automatically;
- Interaction with the map added. Now you can set no-go zones in the app and also send the robot clean a particular room or two;
- Schedule the i7 to work in a bedroom or/and kitchen at once;
- Improved washable dustbin;
- The newer model is quieter;
- Automatic dirt bin makes the i7+ better value and is ideal for pet owners or anyone who doesn’t want to spend time maintaining the robot.
To conclude: The Roomba 980 has a longer battery life and is more suitable for bigger homes but other than that there are no significant pros over the Roomba i7+ considering the fact that the newer model costs about the same having a self-emptying charging dock and many other extra features.
The most powerful robot vacuum cleaner on the market
The Roomba s9 is the newest and might be the best model iRobot has ever released. It has a D-shape similar to a Neato’s body. This model gets new brushless rollers that are 30% wider (compared to the Roomba 600 Series). The latest s9+ has a powerful motor delivering more suction than the Roomba i7.
The Roomba s9+ is the strongest robot vacuum in the industry
The Roomba s9/s9+ has the same features as the Roomba i7 does. It has become stronger, got a new shape, wider rollers, and extended battery life. Whereas the Roomba i7 only has one cleaning mode, the s9+ allows adjusting suction depending on your needs. Because of the redesigned construction, the cleaning rollers get closer to the floor providing deeper cleaning on carpets.
The robot stores up to 10 different floor plans, can be scheduled to work within one or more certain rooms, and identifies carpet flooring by boosting suction to provide deeper cleaning.
With the new wider silicone rollers and self-cleaning charging base, the Roomba s9+ is maintainless
Roomba s9 vs. s9+
The Roomba s9 is a bit cheaper than the Roomba s9+; the base can be bought separately. Other than the auto-empty base option, the Roomba s9 and s9+ is the same robot vacuum.
What/who is the Roomba s9+ best for?
- Big homes. With 120 minutes of battery life, the Roomba s9+ is ideal for bigger homes.
- Multi-level houses.
- Allergy sufferers (thanks to the HEPA filtration).
- Houses with many rooms.
- Pet owners. The new system allows maintaining the rollers even easier than before.
- Homes with carpets. The Roomba s9+ is the most powerful robot vacuum in the industry and is good at deep carpet cleaning.
- Hard surface. The s9+ rollers do a superb job on bare flooring.
- Houses with minimum furniture. The Roomba s9+ shape is good at getting to the corners but struggles in cluttered homes though digital virtual walls (keep-out zones) partially solve this issue.
Who is the Roomba s9+ for?
The Roomba s9+ is ideal for those who have carpets and pets. With 120 minutes of battery life, the Roomba s9+ is ideal for big homes. Because it stores 10 floor plans, the robot is essential for those who live in a multi-level house. In the end, keep out zones feature gives the machine much more value than any other camera-guided robot vacuum. Also, the self-emptied charging base is a new feature you never thought you wanted.
Roomba i7 vs. s9: the main differences
- s9 has a longer battery life (120 min vs. 75 min);
- Roomba i7 is round whereas the s9 has a D-shape;
- The newest model has stronger suction;
- The Roomba s9+ allows adjusting suction depending on cleaning needs.
The Roomba i7/i7+ is better for small and average homes with pets, low and medium-pile carpets, and multi-story houses.
The Roomba s9/s9+ is more suitable for bigger multi-story houses with low and medium-pile carpets and pet owners. It handles carpet cleaning better because of stronger suction.
Even though iRobot does everything for you to make floor cleaning more manageable than ever before, you still need to do some maintenance to make your Roomba work longer. Clean the dustbin from all the dirt and dust collected. Try to do it after every cleaning or as often as possible if you want your machine to last longer. The most important point is to clean the bristle brushes (hello to the newest rubber ones), especially if there is a pet running around your home or your family member has long hair. This is pretty much it. Not much effort to spend on, huh?
The newest Roomba i7+ and s9+ are even easier to maintain. They do not need a dustbin to be emptied after every cleaning and the silicone rollers are made a way that do not get hair tangled so it’s convenient to maintain these models.
