What the differences mean
Warranty
The Dreame D30 Ultra is covered for three years and the Roborock Qrevo Curv 2 Pro for two. For a machine this complex, that extra year is the difference between a worn part being a free repair and an out-of-pocket one.
Runtime
The Roborock Qrevo Curv 2 Pro runs up to 290 minutes on a charge against the Dreame D30 Ultra's 230. On a large single floor the Roborock is more likely to finish in one pass, while the Dreame leans on its auto-recharge more often.
Water and dust capacity
The Dreame D30 Ultra holds a 4.5 L clean-water tank and a 3.2 L dock bag, both larger than the Roborock Qrevo Curv 2 Pro's 4 L tank and 2.7 L bag. In a big home that means fewer refills and fewer bag changes.
Smart home reach
The Roborock Qrevo Curv 2 Pro adds Bluetooth and lists a Matter update that will bring Apple Home and SmartThings, while the Dreame D30 Ultra stops at Alexa, Google Home and Home Assistant. Apple households get a route forward only on the Roborock.
Cleaning under furniture
The Roborock Qrevo Curv 2 Pro is a slim 79.8 mm tall with a retractable LiDAR and a chassis that climbs carpets and thresholds, so it reaches spaces the taller 97 mm Dreame D30 Ultra cannot. If low furniture is the problem, that decides it.
Suction
Both rate their peak suction at 25,000 Pa, so raw power is not the tiebreaker here. What separates them is how much water and dust they carry and how they connect to a smart home.
Which one to buy if
- you want the longest warranty on a high-end robot
The Dreame D30 Ultra carries a three-year warranty against the Roborock Qrevo Curv 2 Pro's two.
- your home runs on Apple Home or SmartThings
The Roborock Qrevo Curv 2 Pro lists a Matter update that brings both, and the Dreame D30 Ultra has no Matter path.
- the robot has to clean a large floor in one go
The Roborock Qrevo Curv 2 Pro runs up to 290 minutes, well beyond the Dreame D30 Ultra's 230.
- you would rather refill water and swap bags less often
The Dreame D30 Ultra carries a bigger clean-water tank and a bigger dock bag than the Roborock Qrevo Curv 2 Pro.
- your furniture sits low and you need the robot to reach under it
The Roborock Qrevo Curv 2 Pro is far slimmer and tucks its LiDAR away, while the Dreame D30 Ultra is taller.

What owners say
Owners of both robots describe a dock that keeps itself going and praise the day-to-day lack of effort. Dreame D30 Ultra owners single out how quiet it runs and how cleanly it lifts long pet hair without the brush tangling, and they call the mapping accurate; the recurring gripe is the cost of pads, bags and brushes not being clear up front, with a few reporting mop pads no longer detected after about a year. Roborock Qrevo Curv 2 Pro owners focus on the near hands-free dock that washes and dries the mops and the fast, accurate setup, and their complaints are about a premium price that still ships without cleaner or a spare bag, plus a robot light that is bright on overnight runs.
