Lab – The washing performance of the Dreame L10s Ultra

Dreame is not at its first attempt in terms of a versatile robot. But this new model, the L10s Ultra, goes even further. In addition to vacuuming and washing the floor, the device itself manages the maintenance of its dust collector and its tank.

If its options and functionalities are multiple, we want to know more about its washing performance. As with steam cleaners and floor scrubbers, we voluntarily soil the floor of our laboratory. Lipstick, carbon black (to imitate soot, for example), oil and soda: all these substances will give the L10s Ultra a hard time.

After a night of drying, we ask the robot to mop the floor, and this time we do not activate the vacuuming functionality. The Dreame then acts in the greatest of silences: its noise level reaches only 49.9 dB. Certainly, in use, it is more common to activate both modes.

We also remind you that the two mops rise up in front of thin carpets, which avoids putting them in the closet or creating prohibited areas via the mobile application.

That is. The device goes back and forth on the spots and that’s a disappointment. Soda, the easiest substance for floor cleaners to remove, is always present, which is not common. If the oil has partly disappeared, it is in reality only a decoy: to the touch, the surface is indeed greasy. As for the other two substances, the most difficult to clean, the L10s Ultra does not perform miracles. The lipstick stains remain as is and the carbon black stains fade, creating streaks behind the robot.

While the efficiency of the Dreame W10 surprised us during the tests, we are disappointed with that of the L10s Ultra. A change of material was made by the Chinese manufacturer, the explanation perhaps residing here…

Anyway, once the washing cycle is finished, the robot returns to its base. He then rinses his mops for 2 min 49 sec and can also dry them with a stream of hot air. We still advise you to put them in the washing machine at 60°.

In the end, the L10s Ultra is obviously a versatile robot, allowing you to keep your home clean on a daily basis. However, for the most manic among you, the device may be insufficient, the washing function not being at the level of the suction function.
