What the differences mean
Navigation
The Roborock Saros 20 uses LiDAR, builds multi-room maps and sets no-go zones. The Eufy 11S MAX uses bounce navigation, with obstacle and cliff sensors but no map and no no-go zones. One can be sent to a room. The other wanders until the battery or a closed door stops it, which is why owners of the Eufy 11S MAX often clean a room at a time.
Mop and station
The Roborock Saros 20 mops with pads the dock washes and dries, lifts them for carpet, doses detergent and self-empties into a 2.5 L dock bin, with a 4 L water tank. The Eufy 11S MAX does not mop and does not self-empty. Its 600 ml onboard bin is larger than the 259 ml bin on the Roborock Saros 20, because that bin is what you empty, not a station.
Suction and noise
The Roborock Saros 20 is rated at 36,000 Pa and 63 dB. The Eufy 11S MAX is rated at 2,000 Pa and 55 dB. The quieter robot is the small one, and owners say it is easy to talk over. The suction gap is the reason the Roborock Saros 20 is the carpet and pet-hair machine, and the Eufy 11S MAX is the daily dust machine.
Connectivity
The Roborock Saros 20 has 2.4 GHz and 5 GHz Wi-Fi and lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter. The Eufy 11S MAX has no Wi-Fi, no Bluetooth and no voice assistant. It is run from a remote, with scheduling on the robot. That is either the point of the purchase or the reason to step up.
Which one to buy if
- you want maps, a mop and a station
The Roborock Saros 20 maps, mops, self-empties and washes the pads. The Eufy 11S MAX does none of those.
- you want no app, no Wi-Fi and a quiet robot
The Eufy 11S MAX is controlled by remote, rated at 55 dB, and owners buy it specifically to skip an account.
- the robot must slide under a low bed or sofa
The Eufy 11S MAX is 72.5 mm tall. The Roborock Saros 20 is 79.8 mm, with far more suction but a slightly taller shell.
- a small hard-floor room is the whole home
The Eufy 11S MAX runs about 100 minutes, holds 600 ml and picks up daily dust without a map to maintain.

What owners say
Owners of both machines praise a floor that looks cleaner with little effort, then split on what that effort is. Roborock Saros 20 owners single out maps that appear in minutes, quiet overnight runs, a body low enough to go under sofas, and a dock they barely open. Eufy 11S MAX owners single out a hum quieter than a fan, a thin shell under beds, and the relief of no app at all. Roborock Saros 20 owners complain that detergent is not in the box and that some thresholds still stop the arm. Eufy 11S MAX owners complain that it repeats rooms, skips the patch by the dock, and that a side-brush motor has failed within a year for some.
