Our verdict
The D20 Air Plus is Dreame's entry-level self-emptying robot and a small one: 325 mm across, 94.7 mm tall and 2.59 kg. Its dock takes the bin into a 4 litre bag for about 120 days, and the robot behind it is better specified than its place in the range suggests: 20,000 Pa with a boost on carpet, a rubber-bristle brush with anti-tangle combs and a tangle-free side brush, a LiDAR that stores four floors, and a 3,200 mAh battery good for 150 minutes and 140 m² in quiet mode. The mop is a flat pad fed by a 280 ml sensor tank, with no lift, and the page names no obstacle sensor beyond the LiDAR, so a cable on the floor is a cable in the brush. There is no bin size, noise figure or threshold height. It is the budget pick for a tidy flat that hates emptying bins.
