The Dreame D20 Air Plus is for people who want strong vacuuming and months without touching a dust bag, while keeping mopping simple. Dreame quotes 20,000 Pa of suction, far above most robots with a basic auto-empty base, and a 4 L bag that it says lasts up to 120 days. That pairing of flagship-level suction with a straightforward base is the reason it stands out.

In its favour
- 20,000 Pa Vormax suction is the highest figure among these seven robots.
- The base empties into a 4 L bag, claimed to hold up to 120 days of debris.
- Dual anti-tangle design on the main and side brushes is aimed at long hair and fur.
Good to know
- The mop is a pad fed by the tank, not rotating pads, and the base does not wash it.
- Obstacle avoidance details are not stated beyond lidar navigation.
Our take
Suction and brushes
Vormax suction is listed at 20,000 Pa, aimed at dust, hair and debris on hard floors and carpets, with Dreame mentioning deep carpet cleaning in the title.
The dual anti-tangle design pairs a main brush that clears hair as it cleans with a side brush shaped to avoid curling and clogging. For homes with pets or long hair, that should mean less time with scissors. Dreame also highlights edge and corner cleaning.
Base and mopping
The base empties debris into a 4 L bag, giving what Dreame calls up to 120 days of hands-free dust collection. Mopping happens alongside vacuuming, fed by an electronic water tank with adjustable flow from a light refresh to a deeper wash. The pad is static and the base does not wash it, so plan to rinse it by hand after mopping sessions.
Navigation and battery
LiDAR handles mapping and route planning, though the listing does not describe obstacle avoidance beyond that. Clear cables, socks and small toys before each run, as nothing in the listing suggests it can recognise them. Battery life is listed at 180 minutes, enough for most homes on one charge, and auto-docking and low noise are named in the feature list. Wood is the listed recommended surface.
D20 Air Plus against nearby picks
The Roborock Q7 BF is simpler, with no self-emptying base and no stated suction. The Xiaomi X20+ adds rotating pads and a mop-washing station, but at 6,000 Pa. The D20 Air Plus offers the most suction of the three and the longest bag interval, but it is the least ambitious mopper, so think about which job matters more in your home before choosing.
Verdict
The D20 Air Plus suits homes that want strong vacuuming, especially on carpets with pet hair, plus self-emptying for months and only light mopping. If mop washing matters more than suction, the Xiaomi X20+ does it in the station. If you want the simplest possible lidar robot with no base tower, the Roborock Q7 BF is the alternative.
