Data from Amazon and official iRobot and Roborock sites.

The Roborock Saros 20 is rated at 36,000 Pa against 13,000 Pa and covers 200 minutes against roughly 120, in a slimmer 79.8 mm body that reaches under low furniture. Its dual spinning mops wash themselves at 212 F, it docks to empty, wash, dry and dose detergent, and it adds a built-in camera for checking on pets. The iRobot Roomba Max 705 Combo still has plenty going for it: an extending roller mop, 5 GHz Wi-Fi and Bluetooth, and the same full list of smart home platforms through Matter. Choose the Roborock Saros 20 for cleaning power and hands-off mopping, and the iRobot Roomba Max 705 Combo only if its iRobot ecosystem and dual-band Wi-Fi matter more than raw performance.

What the differences mean

Suction power

36,000 Pa against 13,000 Pa: the Roborock Saros 20 has close to three times the rated suction of the iRobot Roomba Max 705 Combo, the gap that shows most on carpet and pet hair.

Battery runtime

The Roborock Saros 20 is rated for 200 minutes per charge against roughly 120 on the iRobot Roomba Max 705 Combo, so the Roborock finishes a large floor plan before it needs to dock.

Body height

The Roborock Saros 20 is 79.8 mm tall and reaches under low sofas and beds that the 105 mm iRobot Roomba Max 705 Combo cannot enter, a difference owners notice immediately.

Mop system

The Roborock Saros 20 uses dual spinning mops that wash themselves with 212 F hot water and dry at the dock. The iRobot Roomba Max 705 Combo uses an extending roller mop, which owner reviews link to streaks and puddles.

Camera

The Roborock Saros 20 carries a built-in camera that doubles as a way to check on pets remotely. The iRobot Roomba Max 705 Combo has no such camera, so nothing to watch the house while it docks.

Which one to buy if

What owners say

The two groups are far apart. iRobot Roomba Max 705 Combo owners with a working unit praise the accurate LiDAR mapping, the zone drawing in the app, the smooth navigation and the extending roller mop, and they call the AutoWash dock a highlight for washing and drying the mop automatically. But the dominant theme is reliability: false bin and dirty-water errors, leaking docks, jobs that never finish, mopping streaks and a buggy app, with several units returned. Roborock Saros 20 owners, by contrast, single out the mapping and app, the quiet overnight running, the low-profile body that finally cleans under their furniture, and reliable obstacle avoidance; their complaints are the flagship price, sold-separately mop solution, occasional threshold-climbing trouble and a minority of faulty units.

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.
