What the differences mean

Mopping

The Roborock Saros 20 mops, and its dock washes the mops in hot water, dries them, refills water and doses detergent. The iRobot Roomba Max 705 has no mop at all.

Suction

The Roborock Saros 20 is rated at 36000 Pa, nearly three times the 13000 Pa of the iRobot Roomba Max 705, an edge that shows on deep carpet.

Height

The Roborock Saros 20 is 79.8 mm tall and the iRobot Roomba Max 705 104 mm, so the Roborock cleans under lower furniture.

Dock footprint

The iRobot Roomba Max 705 dock is a small 213 x 172 mm tower weighing 2.3 kg. The Roborock Saros 20 station is 381 x 475 mm and weighs 10.54 kg, since it carries the water tanks.

What owners say

Owners of both robots praise LiDAR mapping that is fast and accurate, strong pet hair pickup and quiet running. iRobot Roomba Max 705 owners, many coming from older Roombas, single out an AutoEmpty dock that lets it run for weeks, and they complain about Wi-Fi setup failing when the router password has special characters, a dock that does not always clear the bin and occasional false stuck errors. Roborock Saros 20 owners talk about an app that splits and labels rooms by itself, a low profile that finally cleans under furniture and a camera for checking on pets, while their complaints are no detergent in the box, inconsistent threshold climbing and faster battery drain on deep-clean runs.
