It raises suction to 36000Pa from 22000Pa, stretches runtime to 200 minutes from 180, joins 5 GHz Wi-Fi and adds a child lock. The Roborock Saros 10R is the less expensive of the pair and holds a little more dust, 270ml onboard and 2.7L in the dock against 259ml and 2.5L. Both docks empty dust, wash and dry the mops, refill water and dose detergent, and both work with Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter. Buy the Roborock Saros 20 for the most suction on rugs and embedded hair, and the Roborock Saros 10R to get nearly the same hands-off routine for less.

What the differences mean

Suction

36000Pa on the Roborock Saros 20 against 22000Pa on the Roborock Saros 10R. On hard floors both are excellent; the extra power is for rugs, where Saros 10R owners find the silicone brushes struggle on thicker pile.

Runtime

200 minutes against 180 is a modest gain. It helps a large home finish in one run, but Saros 20 owners note that deep-clean and carpet runs drain it faster.

Dust capacity

The Roborock Saros 10R holds slightly more, 270ml onboard and 2.7L at the dock against 259ml and 2.5L on the Roborock Saros 20. Not a gap you would notice between bag changes.

Wi-Fi

The Roborock Saros 20 joins 5 GHz networks; the Roborock Saros 10R is 2.4 GHz only, which matters in a home whose router does not broadcast a separate 2.4 GHz band.

Noise

Rated at 63dB for the Roborock Saros 20 and 65dB for the Roborock Saros 10R, close enough that owners of both call them quiet.

What owners say

Owners of both Saros models agree on the core of it: a slim body that finally cleans under their furniture, accurate LiDAR mapping and a quiet run, and both groups complain that no floor cleaning solution ships in the box. Roborock Saros 10R owners, many of them former Roomba owners, single out mops that scrub up paw prints, brushes that stay free of long hair and a riser chassis that climbs high thresholds, while they note heavier water use, a small gap between the mop pads and weaker results on thick rugs. Roborock Saros 20 owners talk more about suction that pulls dust out of floor gaps and a built-in camera for pet checks, and they report mixed threshold climbing, fast battery drain in deep-clean runs and a few faulty units met with slow support.

Upgrading from the Roborock Saros 10R?

Moving from the Roborock Saros 10R to the Roborock Saros 20 buys suction first, 36000Pa against 22000Pa, plus 20 more minutes of runtime, 5 GHz Wi-Fi and a child lock. The body height, the self-washing, self-drying dock with detergent dosing and the smart home support stay the same, and the dust capacity even shrinks a little. If your Saros 10R lives on hard floors and keeps up, there is little reason to switch; if thick rugs or heavy shedding are where it falls short, the Saros 20 is the step that addresses it.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
