The extendable side brush gets deep into
hard-to-reach places like tight corners and around
furniture legs, picking up hair, crumbs, dirt, and
other debris to refresh your home.
Versatile Sweeping with
Side Brush Extend
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 height is defined as the
distance between the top of the brush bristles and
the ground after the side brush has been lifted.

Spotless Carpets – Fewer Worries
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
