Our Verdict

The iRobot Roomba 675 offers some mixed performance with a few very specific high points, like doing an excellent job of cleaning rice from carpets and flour from hard surfaces. However, the 675 does an ineffective job of cleaning your whole house, lacks the intelligence to keep from abusing furniture or avoiding pet droppings, and lacks some of the otherwise standard convenience features and functions. We wish this model had a dust collection system, which we've become accustomed to by testing so many other more capable models. While it may have an attractive price, you'll get what you pay for, and you'll generally be disappointed that you didn't consider a better option. We think you should check out other models in our robot vacuum review.

Our Analysis and Test Results

While the iRobot Roomba 675 might be attractive as a first foray into robot vacuum ownership because of its relatively low price point, you'll get what you pay for dollar-for-dollar with poor overall performance.

Performance Comparison


We purchased the most promising and highly rated robots, then tested them in a series of challenges before awarding scores based on their respective performances. Overall, we determined that the iRobot Roomba 675 is not a worthy candidate for your dollar.

Navigation


A robot vacuum's ability to autonomously navigate an environment is the essence of a robot vacuum. Therefore, we weighted navigation to comprise 30% of each vacuum's overall score, and the iRobot Roomba 675 performed poorly.

While it managed to navigate around furniture okay, the 675 would never finish an area around furniture before moving to a different part of a room. Its movement was also different than that of other Roombas and generally shaky left to right.



Aside from strange navigation that avoided cleaning areas near hard-to-navigate furniture, the iRobot Roomba 675 was quite harsh on furniture and seemed to lack any sense of direction.

Home Coverage


We expect autonomy and enough intelligence from a robot vacuum to cover all areas of our homes; as such, our team tested home coverage. Comprising 20% of each robot's overall score, the iRobot Roomba 675 did a decent job cleaning around edges in our tests but also had some serious faults.

The lack of room-to-room functionality was detrimental to the Roomba 675's performance. Its inability to do multiple rooms, combined with a lack of barrier avoidance and smashing of furniture, left a lot to be desired.

Carpet Cleaning


Carpet cleaning is the only metric where this model did a decent job compared to the other vacuums we tested in our product lineup.

It did an excellent job picking up rice, and great job picking up oatmeal, an above-average job picking up breakfast cereal, and an okay job of cleaning up flour.

It's fair to say that the iRobot Roomba 675 generally does a good job cleaning carpets, and it would suffice to keep a carpeted room clean until your next regular house cleaning.

Hard Surface Cleaning


In our hard surface challenges, the Roomba 675 did a surprisingly good job cleaning rice but struggled to clean oatmeal, leaving behind a pile of oats and dust. It could not pick up breakfast cereal and ultimately dragged some before leaving a lot behind, even after circling back to the mess multiple times.

The Roomba 675 also did a decent job cleaning flour off of hard surfaces, only struggling to extract flour from cracks completely. In general, it is an average performer when it comes to hard surfaces.

Pet Hair


Comprising 10% of an overall product score, we measured each vacuum's ability to pick up pet hair, and the iRobot Roomba 675 did a rather unexceptional job. This model earned a less than stellar score after failing to pick up over 80% of the 5 grams of pet hair used in our test.

Convenience


The iRobot Roomba 675 is a rather feature-lacking robot vacuum. It has no physical remote, and the app lacks many settings and intelligence to improve convenience.

For example, the app lacks convenience-enhancing features and settings such as the ability to draw virtual barriers, adjust suction power, repeat a function, and it has no cleaning map. For the lack of convenience features and functions, the Roomba 675 earned one of the lowest performances our testers awarded for the metric.

Should You Buy the iRobot Roomba 675?


The iRobot Roomba 675 earned one of the lowest overall performances in our product test lineup. While it is one of the most affordable robot vacuum models we've tested, you get what you pay for. While it does a decent job cleaning carpets, it does not excel at anything else. You would be better served by increasing your budget and getting more performance out of other models.

What Other Robot Vacuums Should You Consider?


With an increase in budget, you would be better off considering the Roborock S4 Max, a much more capable robot vacuum, or the iRobot Roomba J7+ for more pet-specific features.
