What the differences mean
Mapping versus bouncing
The iRobot Roomba Plus 505 builds a LiDAR map with rooms, no-go zones and a live position. The Eufy 11S MAX bounces and has no map, no zones and no resume after a charge. One can be sent to the kitchen. The other runs until it has covered what it happens to reach.
Mop and the dock
The iRobot Roomba Plus 505 mops, lifts the pads on carpet, and the AutoWash dock empties the bin and washes and dries the pads. The Eufy 11S MAX does none of that. It vacuums into a 600 ml bin you empty by hand, which is large for a robot with no tower.
App, voice and Matter
The Eufy 11S MAX has no Wi-Fi, Bluetooth or other radio, so Alexa, Google Home, Apple Home and Home Assistant have nothing to talk to. The iRobot Roomba Plus 505 has 2.4 GHz and 5 GHz Wi-Fi, a child lock, and Matter, which is how it reaches Apple Home, SmartThings and Home Assistant as well as Alexa and Google Home.
Size, noise and power
The Eufy 11S MAX is the thin one, 72.5 mm tall and about 2.88 kg, rated near 55 dB and 2,000 Pa for about 100 minutes. The iRobot Roomba Plus 505 is 106 mm tall and 4.3 kg, at 7,000 Pa for about 180 minutes. The Eufy also takes longer to charge, about 6 hours against 4.5.
Which one to buy if
- you want no app, no account and no Wi-Fi
The Eufy 11S MAX is driven by its remote and an onboard schedule. There is no radio for an app or a voice assistant to use.
- the robot should mop and empty itself
The iRobot Roomba Plus 505 mops and its AutoWash dock empties the bin and washes and dries the pads. The Eufy 11S MAX only vacuums.
- you need it under a very low bed
At 72.5 mm the Eufy 11S MAX is much shorter than the 106 mm iRobot Roomba Plus 505.
- you need Apple Home or a room map
The iRobot Roomba Plus 505 maps with LiDAR and supports Matter, including Apple Home. The Eufy 11S MAX has neither a map nor a radio.

What owners say
These owner groups are not describing the same kind of product. Eufy 11S MAX owners praise how quiet it is, how the thin body slides under beds, and that a remote and onboard schedule are enough, with no account to create. They also say it wanders, cannot fence a room, and that a side-brush motor has failed inside a year for some of them. iRobot Roomba Plus 505 owners praise a fast LiDAR map, pet hair on carpet and hard floors, and a dock that empties the bin and washes and dries the pads. They complain that it runs louder than they expected, especially while the dock cleans itself, and that navigation or a stuck bumper shows up after a few months for a portion of them.
