The iRobot Roomba i3+ EVO is a robot vacuum with a self-emptying function, letting it automatically empty debris from its internal dustbin into an external dirt compartment attached to its charging dock. It feels very well-built and does a great job of maneuvering itself too. It performs best on bare floors, where it easily clears small and bulky debris, but it has a hard time dealing with different types of material on carpets. It also struggles when it comes to dealing with pet hair.

Our Verdict

7.6 Bare Floor

The iRobot Roomba i3+ is good for bare floors. This vacuum feels very well-built, does a great job maneuvering itself around obstacles, and recharges very quickly. It's effective in cleaning small and bulky debris from bare floors, though it struggles somewhat when dealing with pet hair. It also incurs high recurring costs.

Pros
  • Excellent build quality.
  • Automatically empties dustbin into large external dirtbag.
  • Easily sucks up rice and cereal.
Cons
  • High recurring costs and demanding maintenance needs.
  • Doesn't clean pet hair very effectively.
5.8 Low-Pile Carpet

The iRobot Roomba i3+ is a middling option for vacuuming low-pile carpets. It picks up a good amount of larger debris but struggles to clear pet hair and fine material. It also has many parts that need periodic cleaning and incurs high recurring costs. That said, it feels well-built and does a great job of maneuvering itself.

Pros
  • Excellent build quality.
  • Automatically empties dustbin into large external dirtbag.
Cons
  • High recurring costs and demanding maintenance needs.
  • Doesn't clean pet hair very effectively.
  • Struggles with fine debris like baking soda.
6.6 High-Pile Carpet

The iRobot Roomba i3+ is an okay choice for high-pile carpets. It can climb onto these sorts of surfaces thanks to its self-adjusting cleaning head height and automatically increases its suction power on carpeted floors. It does an alright job of clearing larger debris, but it has a very hard time sucking up pet hair and especially fine debris. It incurs high recurring costs and has many parts that need regular cleaning.

Pros
  • Excellent build quality.
  • Automatically empties dustbin into large external dirtbag.
  • Automatic surface type adjustment feature.
Cons
  • High recurring costs and demanding maintenance needs.
  • Doesn't clean pet hair very effectively.
  • Struggles with fine debris like baking soda.
4.9 Pets

The iRobot Roomba i3+ is a poor choice for cleaning up pet hair. This vacuum isn't very effective at clearing pet hair from any surface type. It also has many parts that need periodic cleaning and incurs high recurring costs. It does have an allergen-trapping HEPA filter and uses a removable brushroll, making it easier to clear any tangled pet hair.

Pros
  • Equipped with an allergen-trapping HEPA filter.
Cons
  • High recurring costs and demanding maintenance needs.
  • Doesn't clean pet hair very effectively.

Build Quality

The iRobot Roomba i3+ 3550 feels impressively well-built. It has a body made of sturdy plastic, and its rubber wheels feel durable. While the top cover looks like it's lined with woven fabric, it's actually textured plastic. However, its internal dustbin feels somewhat fragile. There are three buttons on top of the robot: a big center one to start and stop a cleaning cycle, and two smaller buttons to send the vacuum home and have it spot clean an area.

The vacuum comes pre-assembled, so all you need to do is set up the docking station, which arrives with a dirtbag already inside.

Design
User Maintenance

The iRobot i3+ has many parts that need to be removed and serviced regularly, but fortunately, they're all easy to access.

  • Dirt Compartment: The dustbin can be removed by pressing the release button on the side of the vacuum. You should empty it after each use by tapping it on the side of a garbage can and wiping any debris from the lid with a dry cloth. If necessary, you can wash it with water, but be sure to remove the filter beforehand.
  • Filter: The filter is located inside the dirt compartment. Clean it by taking out the dirt compartment, pulling out the filter, and tapping it against a garbage can once a week, twice a week in homes with pets. You shouldn't wash it with water.
  • Brushrolls: The brushrolls are easy to access by lifting the brush cover on the bottom of the vacuum and pulling them out. You can remove any tangled hair or stuck-on debris by hand once or twice a month, depending on whether or not you have pets. It can be tricky to put them back because they need to be properly aligned in their housing.
  • Side Brush: This is located under the vacuum and requires a screwdriver to remove. You can clean it by removing any tangled hair or debris once a month, twice a month in homes with pets.
  • Wheel: You can remove the front caster wheel by pulling it out of the vacuum and then pushing it out of its socket. You should clean it twice a month by removing any tangled hair or debris.
  • Sensors and charging contacts: The sensors and charging contacts on the vacuum and docking station should be wiped clean with a dry cloth once a month.
  • Dirtbag: The dirtbag inside the docking station needs to be thrown away and replaced when it's full, which is indicated by a red light on the docking station. You can access it by opening the station's lid and pulling it out. The grey cover on the dirtbag prevents dust and debris from spilling out in the process.

Any part that you can wash under water should be allowed to dry for 24 hours before putting it back in the vacuum.

The iRobot i3 Plus incurs high recurring costs.

  • HEPA Filter: You should replace the HEPA filter every two months.
  • Rubber Brushrolls: You should replace the brushrolls every 12 months.
  • Front Wheel: You should replace the front wheel every 12 months.
  • Side Brush: The manufacturer recommends replacing every 12 months.
  • Dirtbag: The dirtbag needs to be thrown away and replaced when it's full.

iRobot sells a 'Replenishment Kit' on its website that includes brushrolls, three side brushes, and three HEPA filters. The parts are also available individually. Replacements for the wheel can be tricky to find on the manufacturer's website but should be available if you search for the specific part number, 4624869. Take a look at the Shark EZ Robot Self-Empty AV911S if you're looking for a robot vacuum with an external dirt compartment that incurs slightly lower recurring costs.

The iRobot Roomba i3+ has impressive maneuverability. It uses smart pathing to move efficiently, but unlike some other models, it covers an area section by section instead of following one pattern for the entire room. When done, it produces a map of the area it cleaned that you can see in the companion app. Its low-profile design also allows it to clean under most couches and chairs. Its automatic head height adjustment is quite effective, as it lets the vacuum climb onto rugs or over obstructions like rug tassels without getting stuck. That said, while it can climb over electric cords, it does drag them around, and you may need to pick up the vacuum and move it when that happens.

iRobot HOME

The iRobot i3+ has excellent automation features. The vacuum returns to its docking station when its internal dustbin is full, empties it into the station's external dirtbag, and keeps cleaning. It will also return to the dock when its battery is running low and resume cleaning once recharged.

After a cleaning session, the vacuum produces a map of the area it covered that you can see in the companion app. However, unlike pricier models like the iRobot Roomba S9, it doesn't store this coverage map permanently, so you can't set up virtual boundary lines or direct the vacuum to clean specific rooms. The app also allows you to start a cleaning session, send the vacuum back to its dock, make a cleaning schedule, view the cleaning history and battery status, and access app updates and push notifications. It's also compatible with Alexa and Google Home devices, meaning you can control it with voice commands. Otherwise, the robot has buttons on top that allow you to use it without an internet connection.

Differences Between Sizes And Variants

The iRobot i3 has two primary variants. The model without the automatic dirt disposal feature is sold as the iRobot Roomba i3 EVO 3150, while the self-emptying variant we tested is known as the iRobot Roomba i3+ EVO 3550. We can't confirm if the standard i3 performs similarly, as, without the automatic dirt disposal feature, it may lose suction as its internal dustbin fills. Either variant is only available in one color scheme: 'Woven Neutral'. You can see the label of our test unit here.

If you come across a different variant of this vacuum, please let us know in the discussions, and we'll update our review.

Compared To Other Vacuums

The iRobot i3+ is a robot vacuum with an automatic dirt disposal feature. Like the iRobot Roomba i7+, it automatically empties its small internal dustbin into a much larger dirt compartment attached to its docking station. While it is cheaper than the i7+, it lacks some of that vacuum's automation features, like the ability to set virtual boundaries or individual cleaning times for different rooms. It performs best on bare floors but struggles with pet hair on most surfaces.

If you're looking for more options, see our lists of the best robot vacuums, the best robotic vacuums for hardwood floors, and the best robot vacuums for pet hair.

The iRobot feels better-built, has fewer parts that need regular cleaning, charges much faster, does a better job of maneuvering itself, and delivers better performance on all surface types. It also has far more sophisticated automation features, most notably its self-emptying function that allows it to dump debris from its internal dustbin into an external dirt compartment on its charging dock, reducing hands-on maintenance requirements. However, the eufy incurs lower recurring costs.

Shark IQ Robot AV992

The Robot Roomba i3+ EVO is better for most purposes than the Shark IQ Robot AV992. The Roomba i3+ is better built and has a significantly better performance on bare floors. It has an automatic dirt disposal feature, so you shouldn't need to empty its small internal dustbin, and it does a much better job of maneuvering itself. On the other hand, the Shark does a significantly better job cleaning low and high-pile carpets. It also incurs fewer recurring costs since it doesn't use a dirtbag.

Shark ION Robot 2020

The iRobot Roomba i3+ EVO is better than the Shark ION Robot 2020. The iRobot feels better-built, has fewer parts requiring regular maintenance, comes with an allergen-trapping HEPA filter, maneuvers itself more effectively, and performs better on all surface types. It also has a far more advanced suite of automation features, most notably its self-emptying feature, which allows it to dump any accumulated debris into a larger dirtbin built onto its charging dock. It's also capable of resuming an in-progress cleaning session after returning to its dock to recharge. Conversely, the Shark is easier to store, incurs lower recurring costs, and has a much longer battery life, though the iRobot charges a lot faster.

Roborock S6 MaxV

The Roborock S6 MaxV is better for most purposes than the iRobot Roomba i3+ EVO. The two models deliver a fairly similar performance on bare floors and carpets, but the Roborock is better-built, easier to maintain, and incurs fewer recurring costs. You can use its companion app to manually change its suction power and set virtual boundaries to keep the vacuum out of certain areas. On the other hand, the iRobot has an automatic dirt disposal feature, so you shouldn't need to worry about emptying its small internal dustbin.

Neato D8

The Neato D8 is better than the iRobot Roomba i3+ EVO. The Neato has fewer parts that need regular cleaning, incurs lower recurring costs, and delivers better performance on bare floors and carpets. It also has a more advanced mapping system that generates a permanent map of its coverage area, allowing you to set up virtual boundary lines or schedule cleaning sessions for specific rooms. However, the iRobot does have an automatic surface adjustment feature and does a better job of climbing over rug tassels and power cords. This variant of the i3 also has a self-emptying feature, which allows it to dump debris from its internal dustbin into an external dirt compartment attached to its charging dock.

Shark ION Robot R77

The iRobot Roomba i3+ EVO is a better vacuum than the Shark ION Robot R77. The iRobot has a better cleaning performance on all surface types, especially on bare floors, where it has no problem picking up debris like rice and cereal. It also follows a more efficient cleaning path and even returns to the dock automatically to empty its dirt compartment. That said, the Shark's battery lasts quite a bit longer.
