What the differences mean

Navigation

The Roborock Saros 20 uses LiDAR, so it maps in the dark, while the iRobot Roomba Combo 10 Max robot + AutoWash dock relies on a camera (VSLAM) and needs the lights on. Owners of the iRobot name that as its main structural weakness.

Rated runtime

The Roborock Saros 20 is rated for about 200 minutes against about 175 on the iRobot Roomba Combo 10 Max robot + AutoWash dock. On a large floor the Roborock gets further before it has to return and recharge.

Suction

Roborock rates the Saros 20 at 36,000 Pa. iRobot does not publish a suction figure for the Combo 10 Max, so there is no number to set against it, only the Roborock's own rating.

Dock details

The Roborock Saros 20 dock holds a 2.5 L dust bag and doses cleaning solution on its own, which the iRobot Roomba Combo 10 Max robot + AutoWash dock does not. iRobot also does not publish its dock bin size.

Price and bins

The iRobot Roomba Combo 10 Max robot + AutoWash dock is the more affordable of the pair and carries a slightly larger 300 ml onboard bin against 259 ml, so it goes a little longer between trips to the dock.

Noise

Roborock rates the Saros 20 at 63 dB. iRobot does not publish a noise figure for the Combo 10 Max, so the Roborock is the only one of the two with a number to judge.

What owners say

Owners of both robots praise the same fundamentals: mapping that learns the home quickly, a dock that makes day-to-day upkeep small, and app control for schedules and no-go zones. iRobot Roomba Combo 10 Max robot + AutoWash dock owners single out HomeKit control and a dock that washes and dries the pad, then warn that a large share of units fail after a few weeks to months, that the camera needs the lights on, and that support is slow. Roborock Saros 20 owners talk more about the 36,000 Pa suction lifting embedded pet hair, how quiet it runs, and how slim it is under low furniture, while their complaints are the mop solution sold separately, inconsistent threshold climbing and battery drain on deep-clean runs.

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.
