Overview

The L40s Ultra targets mixed-floor homes with pets. Its HyperStream Detangling DuoBrush is designed to resist hair wrap, and Dreame rates suction at 19,000 Pa. The mops can be removed automatically for carpet runs, lift 10.5 mm when needed and extend toward edges along with the side brush.

Dreame's spec sheet lists obstacle crossing of 1.57 in for double-layer steps and 0.87 in for single steps. The base station washes the mops with 167°F hot water, dries them with hot air, adds cleaning solution, refills the robot's water and auto-empties the dust box.
