RTINGS

The best robot vacuum we've tested is the iRobot Roomba S9. This robot vacuum delivers excellent performance on bare floors and does a very good job dealing with debris on low and high-pile carpet, but it might need to make an extra pass to fully clean finer material on carpeted surfaces. Its built-in dirt sensor allows it to focus cleaning on areas with high concentrations of debris, and its vacuum head can automatically change its height depending on the floor type that it's on.

This vacuum has a wide range of other automation features like its vSLAM navigation system, which builds a permanent map of its coverage area, enabling it to plot increasingly efficient routes through your home as it learns the placement of various obstacles. You can use its companion app to set up virtual boundary lines that the vacuum won't enter or direct the vacuum to clean specific rooms at specific times. It can also remember where it left off in a cleaning session if it needed to return to its dock to recharge.

Unfortunately, unlike newer robot vacuums like the Roborock S6 MaxV or iRobot Roomba j7+, it can't identify and maneuver around hazards like pet waste in real-time, so it's best to remove any potential obstacles from the cleaning area before letting it run. In addition, it has many parts that need regular cleaning or replacing, so recurring costs are high, though this is common for robot vacuums. Overall, it's one of the best robot vacuums for carpet that we've tested.

If you're looking for a hands-free means of keeping your floors clear of pet hair, consider the iRobot Roomba S9. This robot vacuum does a fantastic job dealing with pet hair on bare floors and low and high-pile carpet. Thanks to its surface detection system, it can automatically adjust the head height depending on the floor type that it's on. It has a HEPA filter, which is great if you happen to be sensitive to fine allergens.

This vacuum's vSLAM navigation system helps it develop fairly efficient cleaning routes. Since it stores a permanent map of its coverage area, you can use its companion app to set up virtual boundary lines that the vacuum won't cross or schedule cleaning sessions for specific rooms. It can also resume a cleaning session from where it left off if it needed to return to its dock to recharge. It has a maximum battery life of over 2.5 hours, though its runtime can drop to under an hour in its most powerful suction mode.

Unlike some newer robot vacuums like the iRobot Roomba j7+, it doesn't have real-time hazard-avoidance capability, so you should remove any small obstacles like pet waste before the vacuum starts cleaning. It also has many parts that need regular replacing, meaning recurring costs can add up over time, though this isn't unusual for a robot vacuum. Its relatively dense feature set and excellent build quality make it a good option if you're looking for a premium robot vacuum.

If you're looking for a hands-free way of keeping your carpets clean, the iRobot Roomba S9 is a good option. This robot vacuum delivers impressive performance on low pile carpet and does a good job dealing with debris on high-pile carpet, though it might still need to make another pass to fully clean finer debris. Its surface detection system lets it automatically change its brushroll height depending on the surface that it's on, which is handy if you have a mix of high and low-pile carpets in your home. It stores a permanent map of its cleaning area, allowing it to resume a cleaning session from where it left off if it needed to return to its dock to recharge. You can also use its companion app to set up virtual boundary markers or direct it to clean a specific room.

Still, this is a somewhat pricey robot vacuum. If you're looking for something more affordable that's also reasonably effective on carpeted floors, you could consider the Neato D8, which also incurs lower costs of ownership. However, it also has a shorter battery life than the iRobot and gets stuck around furniture more frequently, despite its fairly advanced LIDAR mapping sensor.

If you're a pet owner and want a hassle-free way of keeping your floors clean, the iRobot Roomba S9 is among the best vacuums for pet hair and allergies that we've tested. This premium robot vacuum features an onboard HEPA filter that helps trap allergens as you clean. It does a fantastic job of cleaning up pet hair on a wide variety of surface types and clears a good amount of fine and large debris, like baking soda or sand, from low and high-pile carpets, though it still may need to make another pass to clear it all.

It feels amazingly well-built thanks to its high-grade plastic body and durable rubber wheels. It offers fantastic overall battery performance, though this can vary in the real world depending on your settings. It does a great job maneuvering itself and supports a wide range of automation features. You can use its companion app to set up virtual boundary markers or schedule individual room cleaning sessions. If you'd prefer to not deal with emptying its dustbin, you can buy it with an external dirt compartment built into its charging dock to automatically empty itself of debris.

Unfortunately, like many robot vacuums, many parts need regular cleaning. Several components need periodic replacing, meaning recurring costs can add up over time. Still, its wide variety of automation features, excellent build quality, and versatile overall performance make it one of the best vacuums for long hair that we've tested.

The iRobot Roomba S9 is the best robot vacuum cleaner for pet hair that we've tested. This premium robot vacuum delivers great performance on low-pile carpet, easily sucking up not only pet hair but also fine and large debris. It has an onboard HEPA filter to trap allergens as it cleans, and its brushrolls are easily removable to help you de-tangle any stuck-on hair. Build quality is also excellent, and the vacuum has a relatively large dustbin.

Its vSLAM navigation system builds a permanent map of its coverage area, which you can access through its companion app to set up virtual boundary lines that the vacuum won't cross or direct it to clean specific areas at specific times. Its surface detection system enables it to change its suction power mode depending on whether it's on bare floors or carpet. It can also resume a cleaning session from where it left off if it needed to return to its docking station to recharge.

Unfortunately, unlike newer robot vacuums like the iRobot Roomba j7+, there's no hazard recognition system to let it avoid obstacles like pet waste in real-time, so it's best to make sure its cleaning area is free of any similar obstacles before letting it run. It also incurs high recurring costs and has many parts needing periodic cleaning, though this is normal for robot vacuums. Overall, if you're looking for a hassle-free way of keeping your floors free of pet hair, it's an excellent option.

The best robot vacuum we've tested for long hair is the iRobot Roomba S9. This premium robot vacuum does an incredible job of sucking up pet hair on a wide variety of surface types, ranging from bare floors to low and high-pile carpet. It also has a HEPA filter to trap allergens as it cleans and feels amazingly well-built.

This vacuum's surface detection feature lets it automatically adjust its head height depending on the floor type that it's currently on. You can use its companion app to set up no-go zones or schedule cleaning sessions for specific areas. It's also very maneuverable, as it can easily navigate around furniture or climb over rugs and electrical cords without getting stuck. You can expect anywhere between 50 to 150 minutes of runtime depending on your choice of settings and usage habits, which should be more than sufficient for most areas.

Unfortunately, this vacuum has many parts that need regular cleaning, but thankfully, you can easily remove its brushrolls to clear any tangled hair or stuck-on debris. Quite a few components need periodic replacing, so recurring costs are high. Otherwise, it's an excellent option if you're looking for a robot vacuum that can easily handle long hair on a wide variety of surfaces.

The best robot vacuum for pet hair that we've tested is the iRobot Roomba S9. This high-end robot vacuum does a fantastic job of dealing with pet hair on both low and high-pile carpet, not to mention bare surfaces. It also features an onboard HEPA filter to help trap fine allergens as it cleans. Its twin brushrolls are easily removable to help you clear any tangled hair wraps. The vacuum can automatically adjust its brushroll height depending on the surface that it's on. Its optical navigation system generates a permanent map of its coverage area, letting you set up virtual boundary lines that the vacuum won't cross or direct it to specific rooms within your home. That said, it lacks any sort of real-time hazard-avoidance capability, so you should make sure to remove any potential hazards like pet waste before letting it run.

It also has quite a few parts that need to be replaced over time, so you might want to consider an alternative like the Neato D8 if lower operating costs are important to you. However, it's important to note that the Neato does have a considerably shorter battery life than the iRobot and isn't as maneuverable.

If you're looking for a hands-off method of keeping low-pile carpets clean, consider the iRobot Roomba S9. This premium robot vacuum delivers great performance on low-pile carpets, easily cleaning pet hair and larger debris. However, it might need to make an extra pass to fully clean finer debris. Its surface detection system enables it to automatically adjust its brushroll height once it detects that it's on carpet.

This vacuum's vSLAM navigation system stores a permanent map of its coverage area, so you can create virtual boundary lines that the vacuum won't cross or direct the vacuum to clean specific areas within your home using its companion app. It's fully compatible with Google Home and Amazon Alexa devices, allowing you to control the vacuum with voice commands. It does an excellent job of maneuvering itself around obstacles and can easily climb over electrical cords and other obstructions.

Unfortunately, like most robot vacuums, you do need to replace a few components regularly, including its allergen-trapping HEPA filter and twin rubber brushrolls. This means recurring costs can add up over time. Still, if you're looking for a robot vacuum that's well-built and offers strong performance on low-pile carpets and rugs, it's the best Roomba for carpet that we've tested.

iRobot was founded by the Massachusetts Institute of Technology in 1990 and initially focused on creating robots for scientific and medical use. Their first robot vacuum, the Roomba, was released in 2002, and nowadays, iRobot primarily makes robot vacuums, as well as robot mops. They generally have several models available at different price points, so you can find one that suits your needs and budget. Most iRobot vacuums work with the iRobot HOME app. They're usually well-built and often have an allergen-trapping HEPA filter. Their battery performance tends to be fantastic, and they recharge quickly compared with other robot vacuums that we've tested. However, like most robot vacuums, they often have demanding maintenance needs and high recurring costs.

The iRobot Roomba S9 is the best iRobot vacuum that we've tested. This robot vacuum's iAdapt 3.0 navigation system creates increasingly efficient cleaning routes of its coverage area and enables it to maneuver around obstructions. You can use its companion app to schedule cleaning times for individual rooms or set up virtual boundary markers that the vacuum won't cross. Unfortunately, quite a few parts require regular maintenance or even replacement. The iRobot Roomba 981 is a more affordable option that delivers impressive superb performance on bare floors, though it lacks most of the S9's automation features. Conversely, if you don't mind spending just as much but want more advanced automation capabilities, the iRobot Roomba j7+ can identify hazards like pet waste in real-time and maneuver around them, but it doesn't perform as well on carpets as the S9.

If you're looking for a hassle-free method of keeping your floors clean of pet hair, consider the iRobot Roomba S9. This premium robot vacuum easily cleans pet hair on low and high-pile carpets and rugs, not to mention flat surfaces like hardwood floors. You can quickly remove its twin brushrolls, allowing you to clear any tangled hair. It also features an onboard HEPA filter, which is great if you suffer from allergies.

This vacuum has a fairly advanced set of automation capabilities. Its head height can automatically change depending on the surface that it's on, a handy feature if you have a wide mix of floor types in your home. It can also resume a job from where it left off if it has to return to its charging dock mid-way through a cleaning session, though it needs to fully map out its coverage area for this function to work properly. It can identify areas with especially high concentrations of debris. You can use its companion app to schedule cleaning sessions for specific rooms or set up no-go zones that you don't want the vacuum to enter.

Unfortunately, like most robot vacuums, it incurs high recurring costs, as many parts need periodic replacing. Also, unlike the newer iRobot Roomba j7+, it doesn't have real-time hazard identification capability, so the S9 can bump into obstacles that weren't in place during its mapping run, like pet waste. If you're looking for a well-built robot vacuum that can easily handle pet hair, it's an excellent choice and is one of the best robot vacuums we've tested.

The best multi-surface robot vacuum that we've tested is the iRobot Roomba S9. This robot vacuum has no trouble clearing debris on many surfaces, from laminate floors to high-pile carpet. Its performance remains fairly consistent overall as its relatively spacious dust bin fills, which is good for bigger cleaning tasks.

It feels amazingly well-made, with a high-grade plastic construction that looks and feels premium. Its battery performance is superb, and you can expect roughly between 50 minutes to over 2.5 hours of continuous runtime on a single charge depending on the power mode it uses. Using its companion app, you can schedule cleaning times for individual rooms, check its current battery life, and even place virtual boundary markers to block off areas you don't want it to enter.

However, like many robot vacuums, recurring costs are high due to the number of parts that need occasional replacing. Regular maintenance can also be quite demanding, as many components need cleaning fairly frequently. If you're looking for a robot vacuum that can handle messes on many surface types, this is a good option.

If you don't want to deal with the hassle of vacuuming yourself but still want a vacuum with HEPA-level filtration, consider the iRobot Roomba S9. This premium cordless vacuum has an onboard HEPA filter that traps allergens as it cleans. It does an excellent job cleaning pet hair and other solid debris on bare floors and performs impressively well on low and high-pile carpets. Its surface detection system allows it to automatically change its brushroll height to suit the floor type that it's on. Its iAdapt 3.0 navigation system stores a permanent map of its coverage area, letting you set up virtual boundary lines or direct it to clean specific rooms within your home. It can also resume a cleaning job from where it left off if it needed to return to its docking station to recharge.

It does incur somewhat high costs of ownership, so you might want to consider the Neato D8 if you're looking for a robot vacuum with a HEPA filter that doesn't have as many parts that need periodic replacing. However, the Neato doesn't maneuver itself as effectively as the iRobot and has shorter battery life. If you don't want to spend as much on a robot vacuum with a HEPA filter, the Wyze Robot Vacuum is also worth a look, though it doesn't perform nearly as well on carpeted floors.

Consumer Reports

CR’s take: Part of the newer generation of iRobot models, the iRobot Roomba S9+ is pricey, but it delivers. This vacuum earns top scores down the line in our performance tests, and it’s the best of the best where edges and bare floors are concerned. This is also a self-emptying model that empties its dustbin into a dirt bag, no hands required. Like the iRobot Roomba e5 and the iRobot Roomba 960, the iRobot Roomba S9+ earns a Good rating for data privacy and a Very Good rating for data security. See out full robotic vacuum ratings for more choices.

While Consumer Reports hasn’t tested this model, we expect it to perform much like the iRobot Roomba S9+. The lone caveat is that the S9 does not include the self-cleaning base that comes with the S9+.

CR’s take: The Roomba s9 is iRobot’s top-of-the-line robotic vacuum. It has most of the same navigation features as the Roomba j7, though the s9’s obstacle avoidance isn’t as sophisticated. The big upgrade here is the cleaning power: Thanks to stronger suction and wider brushes, it outperforms all the other Roomba models we’ve tested (and most robots from other brands, too) on our carpet and edge-cleaning tests. It still doesn’t clean rugs anywhere near as thoroughly as a traditional vacuum cleaner, but if strong cleaning is one of your priorities in a robotic vacuum, you could consider this pricey bot. It’s also available with an auto-emptying dock as the Roomba s9+.

One of the latest iRobot models to hit the market, the Roomba S9+ is pricey, but it delivers great performance across the board. The vacuum earns top scores down the line in our cleaning tests, and it’s the best of the best when it comes to cleaning bare floors and edges. This is a self-emptying model that discharges its dustbin into a dirt bag, no hands required. Like the e5 and the 960, the S9+ earns a Good rating for data privacy and an Excellent rating for data security.

This is also a self-emptying model that empties its dustbin into a dirt bag, no hands required. This Roomba offers voice control via Amazon Alexa (as well as Google Assistant) so you can ask your digital assistant to start cleaning for you. The S9+ earns a Good rating for data privacy and a Very Good rating for data security.

CR’s take: The IRobot Roomba S9+ features an easily removable rubber brush roll that moves in a counter-rotating motion. That helps the vac earn an Excellent rating for its ability to pick up pet hair on a medium-pile carpet. This vac also earns an Excellent rating in our bare-floor and navigation tests. It picks up pet hair easily and doesn’t cause any problems with the brush roll.

This is a self-emptying model that discharges its dustbin into a dirt bag, no hands required.

If you suffer from allergies and want a robot vacuum to handle your light-duty cleaning needs, the iRobot Roomba S9 is a solid option. Unlike the comparably-priced Roborock S7 MaxV, this premium robot vacuum lacks a mopping system and has a simpler optical sensor-based system that can't recognize and avoid obstacles in real-time. Still, if you don't want or need these features and want something better at filtering out allergens, it's worth a look. It has an onboard HEPA filter to trap allergens as it cleans and is effective in trapping particles like pet dander. If you want to further minimize the spread of allergens, it's fully compatible with a self-emptying dock that can suck debris from its internal dustbin into an external dirtbag without manual intervention.

However, buying this accessory separately or purchasing it with the vacuum as part of the S9+ bundle does push it into a different price bracket. If you don't mind giving up the onboard HEPA filter, the yeedi vac station offers self-emptying capability at a much lower purchase price. The yeedi also has a passive mopping system, though it isn't especially effective in clearing stains.

The best robot vacuum for pet hair that we've tested is the iRobot Roomba S9. This high-end robot vacuum does a fantastic job of dealing with pet hair on both low and high-pile carpet, not to mention bare surfaces. It also features an onboard HEPA filter to help trap fine allergens as it cleans. Its twin brushrolls are easily removable to help you clear any tangled hair wraps. It can automatically adjust its brushroll height depending on the surface that it's on too. Its optical navigation system generates a permanent map of its coverage area, letting you set up virtual boundary lines that the vacuum won't cross or direct it to specific rooms within your home. That said, it lacks any real-time hazard-avoidance capability, so remove any potential hazards like pet waste before letting it run.

It also has a few parts that need replacing over time, so it isn't the best option if low ownership costs are a significant factor in your purchasing decision. There also isn't a mopping attachment, which could be a deal-breaker if you need a vacuum that can also deal with any mud or dirt your pet might track into your home. It is compatible with a self-emptying base station, but this is a somewhat expensive upgrade.

 I was worried that the new D shape would make it a little more cumbersome for fitting around chairs and table legs. But if you look at it, the Roomba is less wide by about an inch than the other D shaped BOTS, which makes a lot of difference for fitting in tight spaces. I found it was better than any round robot, including the i7, with edge and corner cleaning. Partly because of its shape, it wasn't perfect, but it was a huge improvement over the i7 plus the battery life on the s9 was better in a few ways

 The main change on the s9s clean base was an upgraded filter, so right out of the box. The first thing I tested was the power and it's a beast: it has two power settings and an auto mode, but on high power we measured it at a whopping 22 CFM, which is the highest I've ever measured for context. The Roomba 690 measured 7 CFM, the 980 and i7 were 17 CFM, and the previous champion was the Neto d7, which measured 20 CFM. So we have a new most powerful robot vacuum

 Expensive. You can see the current prices in the description, but it's probably the most expensive vacuum in the world right now. True, it's only a few dollars more than I seven plus was at its peak, but still it's a lot of money. On the other hand, it's probably the best robot vacuum in the world right now, and I know for sure it's the only one

Roomba s9+ Robot Vacuum Review - Just Wow!

I’m currently trial running several auto-empty vacs for our upstairs which has our 4 bedrooms and all carpet. Currently a few weeks into the Roomba S9+ with empty bin and let me just say… while it does a good job picking up on our low rise carpet, the app and technology feels about 5 years behind the Roborock tech and app. If anyone cares about specifics feel free to ask but I’m constantly surprised how poor the app and tech work. Ghost rooms, connection failures, inaccurate post run results… considering how long iRobot has been in the game I’m just really surprised it’s this far behind

 That's because I have to make sure that nothing is left on the floor that could get caught in it. I have to make sure that there are no trays left out or shoes left out, or dangling charging cords. I have to make sure that all furniture is in place and unobstructed. I have to make sure that chairs aren't left jutting out

 I have to make sure that all furniture is in place and unobstructed. I have to make sure that chairs aren't left jutting out. I have to make sure that there are no spills, and nothing left on a counter that could spill since it's not a wet vac. I have to watch out for small things like twist ties that could clog it, or boxes that need to be recycled that could block it

 At $40 for a three pack, it can cost upwards of $400/year if I want to be diligent. It seems to hold up better on smooth floors, but doesn't hold up on carpet. As for cleaning, it handles many surfaces well. It's not so good with others, and terrible with some

Has a lot of potential if they refine their software

Irobot roomba i1+ (1552) or the Shark Ez (RV913S) which should I get??

When it works, it works flawlessly. It really picks up ANYTHING. It even picked up a whole heap of coins that was somehow on the floor.

If I try to mechanically / physically raise the spring contacts, I risk breaking them and making it all the worse. Those should be able and EASY to replace, without needing to disassemble the whole vacuum.

Having to "fix" such a device so it works properly is evidence of bad design. Even worse, when contacting support, the only thing they can do is offer to send a replacement lid, which is not where the problem resides.

But the real problem is that there is a horrible design issue, which should not happen on a device so expensive. There is a persistent "close the lid" problem given that the spring contacts on the body of the S9 are TOO SHORT to reach the contacts on the lid. It is necessary to apply pressure on the closed lid over where the contacts are so that it detects them, or add a bit of aluminum foil with duct tape so that the inner contacts are "larger".

Great potential but defective design on the lid contacts

 Even though the area was completely clear. The problem is due to the lower clearance from the upgraded suction unit, the edge brush get's deformed and smacks the bumper and screws up the sensors. One could probably modify the brush, but I didn't want to deal with it. iRobot says the s9 has 4x the suction of other Roombas, I don't doubt this

 Retuned for the i7+, and am happy with that.  Full review: The in-depth reviews of the s9 were super positive. The Amazon reviews focused on the price. I had a $200 gift card, so I figured "you get what you pay for" and took the plunge

 The Amazon reviews focused on the price. I had a $200 gift card, so I figured "you get what you pay for" and took the plunge. I was super excited when it showed up. The s9 surprisingly has some heft to it

Not for high pile carpet

 Two lap dogs, two teenagers. Does a decent job cleaning, but as expected not as good as an upright. It takes a LONG time to clean the main floor (on the everyday setting). With the mid-cleaning stops for emptying and charging, it takes a full day (it's been runnig for 8 hours today as I type this, and it just returned to base to recharge

s9+ used on main floor (about 1K sq ft). Mixed flooring - carpet in living room and office, hardwood in dining and kitchen. Two lap dogs, two teenagers. Does a decent job cleaning, but as expected not as good as an upright

 Sometimes it's still cleaning when I return home (and it's so random, you can't really put anything down until it's completed the entire cleaning cycle). While the vacuuming part is virtually "no maintenance", you need to frequently clean the rollers, dustbin (yes, take it out and clean it), filters, and sensors to keep it working correctly. I've had it for about three months - seemed to be much better at following a pattern when I first got it, now I see it frequently spinning in circles, repeatedly cleaning an area two times the size of the bot - going over it 3, 4 and sometimes 5 times. Would I recommend it to a friend? Maybe, if they had only a 300 square foot area to have it vacuum
