L40s Ultra simplifies daily cleaning by auto-refilling a multi-surface detergent* when needed, keeping your mops refreshingly clean so your floors stay pristine.
Automatic tank water refilling ensures an uninterrupted water supply for continuous mopping sessions. The dock adds water to the robot vacuum's tank, keeping mops wet.
Keep mop pads clean and odor-free without any effort. The automatic hot air drying prevents mildew buildup, ensuring a consistently fresher and safer home.
