Overview
Dual spinning mops washed with warm water at the dock and dried with cool air pair with a vacuum that empties into a bagged base in this Lefant robot. LiDAR maps several floors, and a slim body lets it clean under beds and sofas.
Self emptying, mop washing and support for both WiFi bands come in a body slim enough for low furniture. The dock relies on dust bags, and the cool air drying trades speed for protecting mop shape.
Who it's for
Multi level homes with pets and low furniture get the slim profile and saved maps. Buyers set against buying dust bags should look at bagless stations.
Pros and cons
- Slim enough for low furniture
- Self empties into a large bag
- Mops washed with warm water
- Works on both WiFi bands
- Dock uses dust bags
- Warm wash rather than hot
- IWatch not included
Performance notes
Coverage comes from LiDAR mapping that plans routes and avoids repeat passes, while obstacle sensing steers around cords and toys. Mopping relies on dual spinning pads; warm water at the dock loosens grime and cool air drying avoids heat warping the pads.
