brand store brand store For anyone in a small, mostly carpeted home, the Dreame D30 Ultra CE works as a vacuum first and a mop second.
No water pump sits inside the Dreame D30 Ultra CE, so its mop pads are wetted only at the station. Just A Dad Approved found the pads had dried out before the robot got to a back bedroom and gave 4 out of 10 for mopping, far under the 7.5 its typical robot gets. The pads do not swing out to the baseboard either, which 84% of robots with a washing station manage. A small kitchen or bathroom near the dock is what it can mop.
Vacuuming is the better half. Its 25,000 Pa of rated suction tops the 19,750 Pa in the middle of its class, yet carpet cleaning earned 6 out of 10, a point short of the tester's norm. The 8 for pet hair came with Dreame's tri-cut brush fitted, and that brush is bought separately. Over three months of daily runs it never got stuck or lost its map.
The station asks for 23.2 inches of height, 3.5 inches more than most.
Product on the market since May 2026
Consumables: a 3.2 l dust bag in the station, which lasts up to 100 days.

What the roller under the robot is made of. Long hair and pet hair slide off rubber rather than wind round it, bristles reach deeper into carpet, and two rubber rollers turning against each other do both.

The side brush swings out in a corner or along a baseboard, so the dust there is swept in too.

The robot notices when it drives onto a carpet. Most then raise their suction, and a mopping robot lifts its mop or leaves it at the dock.
