Dreame D20 Air Plus review

The Dreame D20 Air Plus is the cheapest way on this list to get a robot that maps with LiDAR and empties itself. At $227.99 when we checked, it lists 20,000 Pa suction, far above most robots at this price, though that figure comes from Dreame's own lab. The base station moves debris into a 4L bag that Dreame rates for up to 120 days, and dual anti-tangle brushes are built to keep hair from wrapping. LiDAR mapping saves up to 4 maps, sets no-go zones and, Dreame says, identifies hazards to cut collisions, but there is no camera or structured-light avoidance, so cords and socks are still a risk. Carpet detection raises suction on rugs. The 2-in-1 tank with a flat mop pad is for light wipes only and does not lift. The battery runs up to 150 minutes. It ranks third because the Roborock and Dreame picks above add better mopping. We compared documented features and published prices.
