About this model

A 9.2 for hair, on a ten-point scale where Just A Dad Approved's middle mark is 6.5, is the widest lead the Roborock Saros 20 Flow holds over the field. The tester saw long hair come up without winding round the brush. Vacuuming got a 9, two points over the middle, on suction rated at 36,000 Pa, when 20,000 Pa is common among robots that come with a full wash-and-dry station.

What testers say about the Roborock Saros 20 Flow

A 9.2 for hair, on a ten-point scale where Just A Dad Approved's middle mark is 6.5, is the widest lead the Roborock Saros 20 Flow holds over the field. The tester saw long hair come up without winding round the brush. Vacuuming got a 9, two points over the middle, on suction rated at 36,000 Pa, when 20,000 Pa is common among robots that come with a full wash-and-dry station.

The roller mop went higher again, to 9.4 where 7.5 is the tester's norm, and the review remarks on how little water it needed. That roller is washed in the station with 100-degree water, where the stations of its peers stop at 75 degrees. The climbing system is rated for thresholds of 45 millimetres, more than twice the 20 millimetres others manage, and it crossed the thresholds in the tester's studio smoothly.

With stain detection switched on, the robot still did not recognise spilled ketchup and sucked it up when it should have mopped it, which left the tester with more to clean. In a kitchen that means wiping up anything sticky by hand before a run.
