Dreame L40 Ultra Gen 2 vs Eufy 11S MAX

The Dreame L40 Ultra Gen 2, thanks to a self-emptying dock, far higher suction, multi-floor LiDAR mapping and native Apple HomeKit, Alexa and Google Home support. The Eufy 11S MAX wins on price and simplicity.

Yes, it supports multi-level mapping for up to four floors along with no-go zones and multi-room mapping. The Eufy 11S MAX has no mapping of any kind.

Yes, the dock automatically empties the onboard dustbin, washes the mop pads and dries them with hot air. The Eufy 11S MAX has no dock and no mop, so its bin is emptied by hand.

Some owners report hair tangling in the wheels or main brush over time, which can interfere with navigation until it is cleared, so heavy-shedding households should expect some periodic maintenance.

Buyers with a multi-floor home who want strong suction, a genuinely hands-off dock and wide smart-home support, and who are willing to spend time learning a feature-dense app.

Buyers who want the simplest, cheapest robot vacuum for a single small space, do not need an app or mapping, and prefer a slim body that fits under low furniture.
