Dreame Aqua20 Pro Ultra Roller X Complete
Dreame's steam flagship: 40,000 Pa, a 270 mm roller at 18 N that steams at 180 °C, extends 8 cm and lifts 15 mm, legs for 5 cm sills, a retracting LiDAR and a 100 °C wash.

Our verdict
By Dreame's own footnote, the Aqua20 Pro Ultra Roller X Complete is the first Dreame to pair double hot-steam mopping with an 8 cm extending roller, in each country or region of sale as of its launch there. Water is heated in a boiler to 180 °C at the outlet, 100 °C at the nozzle by Dreame's footnote, and the robot steams a stain, then wipes it with fresh water; two cameras are to trigger that second pass on dried-on marks by a later update. Around it, the Aqua10 recipe enlarged: a 270 mm roller pressed at 18 N and turning at 300 rpm, sliding 8 cm out, 4 cm past the body, lifting 15 mm under the AutoSeal cover on carpet while suction rises, 40,000 Pa behind an anti-tangle DuoBrush, ProLeap legs for a 5 cm sill or a 10 cm double step, a VersaLift LiDAR for a 97.5 mm body, and 320 object types from two AI cameras with structured light. The dock washes at 100 °C, dries at 65 °C, refills, doses detergent and holds 100 days of dust. Dreame prints the 6400 mAh battery and 6.12 kg weight but no runtime, charging time, noise or warranty term, and steam and the extended roller cannot run together. So far Dreame sells it in Germany, not in the US.
Pros
- Steam mopping at 180 °C from the boiler, with a fresh-water wipe after it and, by a later update, automatic re-mopping of dried-on stains
- 270 mm roller at 18 N and 300 rpm that extends 8 cm, lifts 15 mm and seals itself on carpet
- 40,000 Pa behind a TÜV-certified anti-tangle DuoBrush, with brushes that lift too
- Legs for 5 cm sills and 10 cm double steps, LiDAR retracted to 97.5 mm
- Dock washes at 100 °C, dries at 65 °C, refills, doses detergent and stores dust for 100 days
Cons
- No runtime, charging time, noise figure or warranty term published
- Steam and the extended roller cannot be used at the same time; room-mode steam and the automatic re-mop wait for an update
- 6.12 kg, the heaviest Dreame robot vacuum we list
- Not in Dreame's US shop; listed in Germany
Best for
- Kitchens with greasy or dried-on stains, where steam does what pads cannot
- Homes with sills, rugs and pets, where the legs, the lift and the pet features all count
Not recommended for
- Anyone who needs a published runtime
- Anyone who wants to buy from Dreame in the US

In detail
Suction and brushes
The manufacturer rates the suction at 40,000 Pa. That is more than 93% of the 114 robot vacuums we list. The main brush is the tangle-resistant type, with one side brush. On carpet the suction rises automatically. The onboard bin holds 180 ml.
Mopping
Mop system: washed roller. It lifts the mop 15 mm over carpet. The mop swings out to reach along walls. The onboard water tank holds 135 ml.
Navigation and obstacles
It navigates by retracting LiDAR and avoids obstacles with camera + depth sensor. It climbs thresholds up to 50 mm. That is more than 93% of the 71 robot vacuums with a published figure. No-go zones can be drawn in the app. Its maker says it recognises pets.
The dock
The dock empties the bin, washes and dries the mop and refills the water tank. The dust bag lasts about 100 days.
Battery, charging and noise
The manufacturer publishes neither a runtime nor a noise figure.
