About this listing

Who it suits
Homes with lots of edges, table legs and low gaps. Its two spinning mops extend up to 1.57 in toward edges and under low furniture and lift 0.41 in on carpet, and the dock empties for up to 100 days, washes the mops, hot-air dries them and refills the water.

L40 Ultra Gen 2 or D30 Ultra?
Both have 25,000Pa suction. The L40 Ultra Gen 2 reaches further with its mops (up to 1.57 in) and hot-air dries them; the D30 Ultra air-dries its mops and comes with a TriCut brush. Dreame sells the TriCut brush separately for the L40.
