Is the Dreame D20 Plus right for your home? Find out in 7 questions →Vacuum Wars gave the Dreame D20 Plus 4.77 out of 5 for finding its way through rooms, where 3.145 is that lab's halfway mark, and no points at all for avoiding what lies in them. The robot carries no sensor for objects, and of the 24 items set in its path it dodged none. Cables, socks and toys therefore come off the floor before each run. Just A Dad Approved was milder, marking obstacles 6 on a ten-point card whose median is 7.5, and found a tidy room fine and a cluttered one too much.

brand store brand store Vacuum Wars gave the Dreame D20 Plus 4.77 out of 5 for finding its way through rooms, where 3.145 is that lab's halfway mark, and no points at all for avoiding what lies in them. The robot carries no sensor for objects, and of the 24 items set in its path it dodged none. Cables, socks and toys therefore come off the floor before each run. Just A Dad Approved was milder, marking obstacles 6 on a ten-point card whose median is 7.5, and found a tidy room fine and a cluttered one too much.
On carpet, Vacuum Wars saw 93 per cent of the sand it had worked in come out again, well clear of the lab's average, and not one long hair left wound round the brush. Long hair passed through cleanly for Just A Dad Approved too, whose carpet mark of 7.8 beats the 7 it hands a middling robot. Dreame's 13,000 Pa is more than twice the 6,000 Pa usual for a robot docked at a station that empties the bin and does nothing else, and its 285 minutes per charge outlast the customary 175 minutes by nearly two hours.
A 5-liter dust bag sits in that station, and Dreame counts on 150 days between changes, with 60 days normal for its kind. The mop is a single pad dragged behind the robot, never lifted over rugs and never washed by the station, and Just A Dad Approved advised leaving it off.
Product on the market since August 2025
Consumables: a 5 l dust bag in the station, which lasts up to 150 days.
Dimensionsrobot and dock
From the published dimensions. The robot passes under furniture with 3.8 in of clearance or more. The dock needs a spot 17.3 in wide and 11.7 in deep.

Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
