At 3.6 inches tall and 45dB quiet, it fits under furniture and schedules that bigger, louder robots cannot. Matter and Apple Home native.

Gavler Meta-Score
“The K11+ is the robot vacuum for apartments, small homes, and noise-sensitive households. The 45dB quiet mode is not marketing — it is genuinely silent. The compact size accesses under-bed and under-couch spaces that larger robots bump against. Smart home support is the broadest of any robot at this price. 6,000Pa suction will not deep-clean thick carpet, but for hard floors and low-pile rugs, it is more than adequate. At $400 (frequently on sale for $269), it is an exceptional value.”
The Gavler Verdict
Genuinely inaudible from the next room — run it during calls, meetings, or sleep without disturbance.
3.6-inch height and 9.8-inch diameter access spaces that standard robots cannot reach.
Native support for Matter, Apple Home, Alexa, and Google Home — the broadest ecosystem compatibility.
Compact size and whisper-quiet operation are standout features. Suction trails larger robots on thick carpet.
