The iRobot Roomba 675 is a disappointing overall robot vacuum. It's a decent choice if you want to clean rooms with bare floors as it cleans most small and large debris but still struggles a bit with hair. Its performance drops when it's on carpet, as it has a hard time cleaning any type of carpet. Luckily, it has an outstanding battery life, so you won't have to worry about charging it for a while. Unfortunately, you need to clean many different parts and you need to buy replacements to a few parts and tools often. The iRobot HOME app doesn't offer many features, either. However, this vacuum has a great build quality.

Our Verdict

6.7 Bare Floor

The iRobot Roomba 675 is okay to use on bare floors. It cleans most debris on bare floors well but struggles a bit with hair. It doesn't have a precise cleaning pattern but it still cleans an entire room. Unfortunately, it's not easy to maintain as there are quite a few parts that need frequent cleaning and there are a few recurring costs associated with the vacuum too.

Pros
  • Great build quality.
  • Decent performance on bare floors.
  • Outstanding battery life.
Cons
  • Struggles with hair.
  • Not easy to maintain.
  • High recurring costs.
5.6 Low-Pile Carpet

The iRobot Roomba 675 is disappointing on low-pile carpet. It's able to clean large debris but really struggles with any small debris like baking soda. It's not easy to maintain and there are a few parts that need replacing every few months. On the upside, it has good maneuverability and it has an automatic surface type adjustment.

Pros
  • Great build quality.
  • Outstanding battery life.
Cons
  • Poor performance on carpets.
  • Struggles with hair.
  • Not easy to maintain.
  • High recurring costs.
5.4 High-Pile Carpet

The iRobot Roomba 675 is a poor choice for use on high-pile carpet. It's able to get up onto carpet but it has trouble cleaning any type of debris. However, it has an automatic surface type adjustment that adjusts the height of the vacuum so you don't have to manually switch it.

Pros
  • Great build quality.
  • Outstanding battery life.
Cons
  • Poor performance on carpets.
  • Struggles with hair.
  • Not easy to maintain.
  • High recurring costs.
5.4 Pets

The iRobot Roomba 675 is a poor vacuum if you want it to clean pet hair. It doesn't suck up much hair on any type of floor and the vacuum itself isn't easy to maintain. You can remove the brushroll if hair gets wrapped around it and you'll need to replace the brushroll every 6-12 months.

Pros
  • Great build quality.
  • Outstanding battery life.
Cons
  • Struggles with hair.
  • Not easy to maintain.
  • High recurring costs.

Build Quality

The iRobot Roomba 671 has a great build quality. It's made out of hard plastic with a glossy finish on top and matte finish on the bumper. The dirt compartment, which has a built-in exhaust, has a foggy plastic cover on top that you can still see through it, but it still feels like it could break if dropped. Like most robot vacuums, there's no assembly required for the vacuum itself, and you only need to assemble the charging dock. There are three buttons on the top to initiate different commands, such as cleaning, spot clean, or return to the dock, and there are battery indicator lights above the buttons. This vacuum also has a carrying handle and there are built-in speakers to notify you of the vacuum's status, such as when it starts or finishes a cleaning session.

User Maintenance

The robot vacuum is a bit difficult to maintain, as there are a lot of parts that need maintenance, but they're easy to take off and clean.

  • Dirt compartment: It needs to be emptied after each use and it can't be washed with water.
  • Brushrolls: There are two brushrolls: the bristle brush and the beater brush. They need cleaning about once a week, and if you have pets that shed, you should clean them twice a week.
  • Filter: The filter can be removed after emptying the dirt compartment and you clean it by tapping it along the edge of a garbage can. Like the brushrolls, it should be cleaned once a week, or twice a week if you have pets.
  • Side brush: The side brush should be cleaned once a month, but you need a screwdriver to remove it.
  • Wheels: The wheels should be cleaned about once every two weeks and they're easy to take out. You can see if there's debris stuck in the wheels by spinning them by hand while they're still in the vacuum.
  • Sensors: The sensors on the vacuum should be cleaned once a month with a dry cloth.

Update 07/10/2020: We originally wrote that the side brush needs to be replaced every 12 months. However, it doesn't have a regular replacement time and it should be replaced when it becomes worn down. We also added the replacement time for the front caster wheel.

There a few parts that need replacing and you can buy them on iRobot's online store. The AeroVac filter needs to be replaced every two months, the brushrolls every 6-12 months, and the side brush when it becomes worn out. The front caster wheel also needs to be replaced every 12 months.

iRobot sells a kit with three filters, the bristle brush, beater brush, a side brush, and a cleaning tool for the brushes. You can purchase any other part that breaks or needs replacement off their website.

Update 07/10/2020: We originally reported that the height of the vacuum was 15.83 in (40.20 cm) while its depth was 3.94 in (10 cm). We have corrected these numbers.

Like most robot vacuums, the iRobot 671 is extremely easy to store. The vacuum mounts itself onto the charging dock and it lays flat on the ground.

The iRobot Roomba 671 has a disappointing dirt compartment. It's small and there's no indicator telling you if it's full, so you have to monitor it yourself. If you want a slightly bigger dirt compartment, check out the iRobot Roomba E5.

The iRobot Roomba 671 has incredible battery life. It doesn't have any manual power adjustment settings, as it automatically changes its suction power based on the cleaning conditions. It lasts two hours, and it takes just as long to charge, which is great for a robot vacuum. There's a battery indicator light on top, and it turns red when the battery is low, but it doesn't specify the battery percentage. The mobile app also notifies you when the battery is low.

The iRobot Roomba 671 has a few extra features that help its cleaning experience. The vacuum automatically detects the type of floor it's cleaning and adjusts its height depending on it. It also detects when there's dirt, so it increases the suction power over that area. Both of these features are automatic and you can't change them.

Setting Used "Clean"

The iRobot Roomba 671 has okay performance on bare floors. It struggles with hair but doesn't have too many problems with both small and large debris. Its beater brush can crush large debris, making it easier for the main brushroll to clean, but some debris still gets pushed around by the side brush and the vacuum doesn't pick it up. If you prefer a robot vacuum with better performance on bare floors, check out the eufy RoboVac 11S.

Poor performance on low-pile carpet. It cleans up a bit more hair than it does on bare floors and it still cleans an impressive amount of large debris like sand. Unfortunately, it struggles to clean fine objects like baking soda. This vacuum cleans a lot less on low-pile carpet than the iRobot Roomba 960.

Unlike some other robot vacuums, the iRobot 675 doesn't have an issue getting onto high-pile carpet, but once on, it doesn't perform well. It can't pick up most debris but still sucks up some pet hair. If you're looking for a robot vacuum with better performance on carpet, check out the Neato Botvac D7.

This robot vacuum has decent maneuverability. Its automatic surface type adjustment makes it easy to clean a room, especially if you have carpets or rugs in a room with bare floors. It doesn't have a precise cleaning pattern and rarely goes in a straight line but it still cleans the entire room. It's able to go underneath couches and tables without any issues, and it cleans around and goes over wires. It's also able to go over rugs and clean them but it could still drag them a bit.

iRobot HOME

The iRobot Roomba 671 has poor automation features. The buttons on top enable it to start a cleaning session, do a spot clean, or return to its dock. The iRobot HOME app doesn't add much as it gives you the same virtual buttons as the physical buttons on the vacuum. Also, the app notifies you of its battery status and you can schedule cleaning sessions. The vacuum is also compatible with Google Home and Alexa. If you want a robot vacuum with a smart pathing feature, check out the Roborock S4.

Differences Between Sizes and Variants

We tested the iRobot Roomba 675, which is only available in black. It's sold as iRobot Roomba 671 in Europe. There's a variant of this vacuum, the Roomba 605, which doesn't have app support. Besides automation, we expect our results to be valid for the other variants, which are listed below.

U.S. Model Name EU Model Name App Automation
Roomba 605 Roomba 605 No
Roomba 675 Roomba 671 Yes

If you come across a different variant of the 671 or 675, let us know in the discussions below and we'll update the review.

Compared to other vacuums

The iRobot Roomba 675 robot vacuum is disappointing and compared to other robot vacuums, it doesn't perform well. It's not easy to maintain and it doesn't perform very well on bare floors either. There are better robot vacuums that you can get instead, such as the eufy RoboVac 30C. Also see our recommendations for the best robot vacuums, best robot vacuums for pet hair, and best vacuums.

iRobot Roomba E5

The iRobot Roomba E5 is a bit better overall than the iRobot Roomba 675. The two robot vacuums are very similar and have the same features. The E5 performs much better on both low-pile and high-pile carpet, and it also has a bigger dirt compartment. However, the 675 is a bit better on bare floors and its battery lasts longer.

Roborock S4

The Roborock S4 is much better than the iRobot Roomba 675. The Roborock has much better performance on bare floors and low-pile carpet, but it can't clean on high-pile carpet, while the iRobot can clean some hair on high-pile carpet. The Roborock also has better automation features and a bigger dirt compartment. The battery on the iRobot takes less time to charge. 

eufy RoboVac 11S

The iRobot Roomba 675 is a bit better overall than the eufy RoboVac 11S. It's easier to maintain, there are less recurring costs, it's better built, and it has a better battery life. However, the eufy has better performance, especially on carpet, and it's a better choice if you have pets.

eufy RoboVac 30C

The iRobot Roomba 675 is better than the eufy RoboVac 30C. The iRobot has a better battery life, build quality, and it has better performance on bare floors and carpets. The eufy has two side brushes, while the iRobot has one, but they need to be replaced every three to six months.

Roborock S5

The Roborock S5 is much better than the iRobot Roomba 675. The Roborock performs much better on bare floors and carpets. It also has a bigger dirt compartment and it has more automation features. On the other hand, the iRobot has a better battery since it takes much less time to recharge.

Roborock E4

The Roborock E4 is a better overall vacuum than the iRobot Roomba 675. The Roborock performs significantly better on all surface types, has a larger dirt compartment, and has longer maximum battery life. It also has a broader range of automation options, like the remote piloting feature in its companion app and efficient smart pathing. Meanwhile, the Roomba is lighter and charges faster.

Neato Botvac D7

The Neato Botvac D7 is a better overall performing robot vacuum than the iRobot Roomba 675. The Neato does a better job of picking up all kinds of debris on all surface types, including pet hair. It's also easier to maintain, it has a larger dirt compartment, its battery has a slightly shorter charge time, and you can also control it using the companion app as a remote control. However, the iRobot has slightly less recurring costs, and it's lighter. 

Samsung POWERbot R7040

The Samsung POWERbot R7040 is better than the iRobot Roomba 675. It cleans a bit better on bare floors and its performance on low-pile carpet is significantly better. The Samsung also has less recurring costs and it's easier to maintain. The iRobot has a better battery life and it has a side brush that helps clean debris in hard-to-reach areas.
