About

About Dreame L40s Series

Dreame L40s Series is a family of three robot vacuum-and-mop systems for routine household floor care. All three models use lidar navigation, rotating mop pads and a 5,200 mAh battery, with app control for maps, schedules and cleaning zones. Their docks handle dust emptying and water servicing between runs.

The L40s Ultra and Ultra AE advertise up to 19,000 Pa suction, while the Ultra CE advertises 13,000 Pa. The Ultra adds auxiliary wheels for specified two-layer thresholds and extends both its side brush and mop; the AE extends its mop, while the CE has neither extension. Obstacle sensing and dock washboard functions also vary. These are distinct configurations within one family, so a capability or maximum figure from the Ultra does not describe every L40s model.
