Seamless Cleaning with a Liftable Side Brush
L40 Ultra's side brush rises over 0.39in (10mm), working with the mop and main brush to separate wet and dry cleaning tasks. The robot vacuum smoothly switches between carpets and floors, preventing mess crossover while sweeping and mopping.*10mm (0.39in): Based on tests in Dreame Lab. The lifting heighit is defined as the distance
between the top of the brush bristles and the ground after the side brush has been lifted.
L40 Ultra protects carpets from moisture by removing or lifting mops to 0.4in（10.5mm）*. You can also set zones to avoid rugs, preventing the vacuum from getting stuck. ⁤⁤To deep clean your rug, choose Suction Boost** or Intensive Carpet Cleaning Mode***.

0.4in（10.5mm）: The height difference of the robot vacuum is 0.4in（10.5mm） before and after mop lifting. For carpets with piles longer than 3mm(0.12in), we suggest you set the robot vacuum to avoid medium and high-pile carpets via the Dreamehome App and protect your carpets from getting wet.
*Suction Boost: This mode is available in the Dreamehome App. Once the carpet is detected, the robot will clean the carpet with maximum suction power. Not available under quiet suction mode.

    Just got my L40 and after a bit of trial & error I think I have it set up pretty good

    Just got my L40 and after a bit of trial & error I think I have it set up pretty good. It takes a bit to get it the way you want it. Moving area rugs, moving cables, garbage cans ect. but once its setup will be great.
