Dreame L40s Ultra

The dock holds a 3.2 L dust bag and empties the robot's 310 mL onboard bin automatically after each run. Most households go weeks before the bag needs replacing.

The robot stands 3.8 inches tall, so it slides under many couches, beds, and cabinets. The dock is larger at 23.2 inches tall and 18 inches wide, so plan clearance near an outlet.

Yes. It clears obstacles up to 40 mm, so most door sills and floor transitions between rooms are no problem.

It uses an extendable side brush and an extendable mop that reach out toward walls and corners. Both lift on carpet to keep messes off your rugs.

It supports Amazon Alexa, Google Assistant, and Apple. You can start, stop, or schedule cleaning by voice, plus set no-go zones and pick specific rooms in the app.
