Dreame D30 Ultra vs Roborock Qrevo Curv 2 Pro

Full Robot Vacuums comparison in 2026

Updated October 2026
Data from the official Dreame and Roborock sites.
2026 verdict
The Dreame D30 Ultra is the better value in this robot vacuum face-off against the Roborock Qrevo Curv 2 Pro.
It carries the longer warranty, holds more clean water and a larger dock bag, and matches the Roborock's top-end suction, so on the everyday job of running a floor unattended the two clean alike. The Roborock Qrevo Curv 2 Pro answers with a longer battery, Bluetooth for easier pairing, a slimmer body that slips under low furniture, and a Matter path that will add Apple Home and SmartThings. Both mop with self-washing, self-drying docks and both reach Home Assistant. Buy the Dreame D30 Ultra if warranty length and less-frequent refills matter most, and the Roborock Qrevo Curv 2 Pro if you need the longest runtime or a smart home ecosystem beyond Alexa and Google.

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.

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.
