Roborock Saros 20 vs SwitchBot K11+

The Roborock Saros 20 for raw cleaning power, battery, 5 GHz Wi-Fi and a full self-cleaning mop system. The SwitchBot K11+ is the better buy for tight spaces, quiet and value, with a much smaller body and a bigger dock bin.

Suction and size. The Roborock Saros 20 is rated at 36,000 Pa with dual washing mops, while the SwitchBot K11+ is rated at 6,000 Pa in a 248 x 248 x 92 mm body built to reach tight spots.

Only lightly. The SwitchBot K11+ uses a pre-moistened wipe pad with no detergent, washing, drying or carpet lift, so it is fine for a light wipe but not a replacement for mopping. The Roborock Saros 20 has a real self-washing mop system.

The SwitchBot K11+ at 45 dB, against about 63 dB for the Roborock Saros 20. That makes the K11+ the easier one to run in a small, open apartment.

The SwitchBot K11+ at 4 L against 2.5 L for the Roborock Saros 20. It goes longer between bag changes, though the Roborock's dock washes, dries and refills its mops on its own.

Someone in an apartment or a cluttered home who wants a small, quiet, self-emptying vacuum that reaches under low furniture and around chair legs, and who does not need a scrubbing mop.
