Top 5 Slim Robot Vacuum Cleaners Worth Considering


One of the parameters that you need to pay attention to when choosing a robot vacuum cleaner, is its height. The size of the body determines the device's maneuverability under low furniture. The lower the robot, the more dirty areas it can reach and clean. In 2021, a record-low height of just 3 cm was considered a record low, while the standard height of popular models is 8-10 cm. However, most ultra-thin robots have already been discontinued due to their low efficiency. This is due to the small dust bin capacity and minimal components, as manufacturers compete for this minimal height. As a result, in 2021, robot vacuum cleaners up to 8 cm in height are considered good thin ones, with 6 cm being ideal. In this article, we'll look at the thinnest robot vacuum cleaners worth considering (!), ranking them from best to worst (not by height).

We also recommend watching our video version of the ranking of thin robot vacuum cleaners for the first half of 2020:
















I want the first robot, it's the thinnest, 3 cm. I measured the distance between the floor and the beds, it turned out to be 4 and 6 cm, so if I were to buy one, I'd take the very first slim one.
Take it, you won’t regret it, it’s a good model!
I bought the Slim Clover Clean, and I love it. I live in a small studio apartment, and this robot is convenient. It cleans under furniture and in the middle, without making a hum, and without a base, it doesn't clutter the space. I charge it, put it in a closet, and then turn it on when I need it.
Here's a question? What are the sizes of these robots, including wheels? I was fooled when I bought a robot, and they said it was 6 cm. But I bought it, measured it, and it's a whopping 6.7 cm with wheels. And now it doesn't fit under furniture.
Hello! This is all up to the manufacturer. Some actually list the height of the robot's body, not the height measured from the floor. In the photos in the ranking, we measured the robots we tested with a ruler.
