Full review
01Design & simplicity
The 11S MAX has no Wi-Fi, no map, and no account signup — you press a button (or use the included TV-style remote) and it goes. At 2.85 inches tall it ducks under sofas and beds that block every premium robot we own, which in real homes recovers more dust than an extra 2,000 Pa of suction ever would.
02Vacuuming performance
Suction is modest on paper at 2,000 Pa, but BoostIQ kicks power up when it senses carpet, and pickup on hard floors hit a respectable 88% in our lanes. On low-pile carpet it manages 78%; thick pile is beyond it. Because navigation is random, coverage comes from time rather than planning — in a one-bedroom apartment a 100-minute run touches essentially everything, while in a large open plan it can miss whole regions.
03Living with it
It is the quietest robot in our fleet at 55 dB on hard floor — conversation-friendly in a way no self-empty dock ever will be. Maintenance is manual: you tip the 600 ml bin yourself and de-fuzz the bristle brush weekly with the included tool. The single side brush sheds its arms every few months; replacements are cheap and everywhere.
04Who should buy it
Buy it for a small space, a rental, an elderly parent, or anyone who wants cleaner floors without an app. Skip it for large or heavily carpeted homes — random navigation and 2,000 Pa both run out of headroom there.
