Full Robot Vacuums comparison in 2026

Updated October 2026
Data from Amazon and official iRobot and Roborock sites.

It also mops, something the vacuum-only 205 cannot do at all, and its dock empties, washes, dries and doses detergent on its own, reaching Apple Home, SmartThings and Matter along the way. The iRobot Roomba 205 answers only with the much lower price, and both are rated similarly by their owners. Buyers who genuinely only want vacuuming, and want to spend far less, should pick the iRobot Roomba 205; anyone who wants mopping and self-emptying handled without lifting a finger should choose the Roborock Saros 20 Sonic.

What the differences mean

Mopping

The Roborock Saros 20 Sonic vacuums and mops, with the mop washed, dried and dosed with detergent at the dock. The iRobot Roomba 205 has no mopping hardware.

Suction power

The Roborock Saros 20 Sonic is rated at 36000Pa against 7000Pa for the iRobot Roomba 205, a large gap.

Self-emptying

The Saros 20 Sonic empties its own bin. The Roomba 205 relies on internal compaction and a compact charging base, but still needs manual emptying eventually.

Battery life

The Saros 20 Sonic runs 190 minutes per charge against 120 minutes for the Roomba 205.

Smart home platforms

The Saros 20 Sonic reaches Apple Home, SmartThings and Matter. The Roomba 205 reaches none of the three.

Price

The iRobot Roomba 205 is dramatically cheaper, which matters most for a buyer who genuinely only vacuums and has no interest in paying for a mopping dock they will not use.

What owners say

iRobot Roomba 205 owners like that the internal DustCompactor lets the bin go far longer between emptyings without a bulky auto-empty tower, and consistently praise the LiDAR mapping as quieter and more accurate than the camera-based robots they had before, including working reliably in the dark. The complaint that comes up most is battery life, with several owners needing two or more recharge cycles to finish a single level of a larger home, and a few report the robot getting stuck on loose cords or thresholds.
