Dreame D20 Air Plus

The D20 Air Plus vacuums and mops in the same pass, with a dock that only empties the dust box: it does not wash or dry the pad, which comes off and is washed separately. A laser turret on the lid builds the map; with no second obstacle sensor, the robot meets furniture and objects with its bumper, so cables and toys have to be picked up before a run. The dual anti-tangle brush is designed not to trap hair and pet fur, and a HEPA filter catches fine dust in the bin.

The water tank and the dust box share the same 280 ml compartment: a sensor sets the pad's moisture, and a second sensor raises suction on its own over carpets and rugs. The battery is rated for 150 minutes of continuous cleaning and charges in about four and a half hours; Wi-Fi is 2.4 GHz only, and voice commands go through Alexa, Google Home or Siri on a separate device.

With no camera or microphone on board, the robot records no images or audio of the home. It suits someone who wants a first robot with automatic dust emptying, at the lowest price in the D range, and is fine washing the pad by hand and clearing the floor before each run.
