Dreame X50 Ultra vs Roborock Qrevo Edge 3 Pro
By Emma Walsh
Most robots in our list that give a figure stop at a 2 cm door sill, and only six are under 9 cm tall. These two were built for houses where both of those are a problem, and they go about it in much the same way. Each has spinning mop pads and a dock that does everything down to adding the detergent. The gaps between them are a few millimetres of climb, a centimetre of height, a lot of suction and one price band.

Choose the X50 Ultra if
- Your tallest sill is 4.2 cm or lower and you'd like to stay a price band down
- Your floors are mostly tile or timber, where 36,000 Pa would have little to do
- Nothing in your house sits lower than 9 cm off the floor
Choose the Qrevo Edge 3 Pro if
- Your tallest sill is between 4.2 and 4.5 cm
- The gap under your couch is between 8 and 9 cm: it's 7.98 cm tall against 8.95 cm
- You have a lot of carpet: 36,000 Pa is the strongest suction in our list
Sills and low furniture
Both of these are here for the same reason, which is getting over a sill that a 2 cm climber treats as a wall. The X50 Ultra climbs a single step of 4.2 cm and the Edge 3 Pro climbs 4.5 cm. Three millimetres only matters if your sill happens to fall between the two, so measure it, on both sides, before you let that number decide anything.
The Roborock is 7.98 cm tall and the Dreame is 8.95 cm, and a centimetre is a real difference under furniture. If the space under your couch is 8.5 cm, one of these goes in and the other cleans around it. Only one robot in our list is lower than the Roborock.
Suction and carpet
The Edge 3 Pro has 36,000 Pa of suction, the strongest in our list, and the X50 Ultra has 20,000 Pa. No other gap between these two is as wide. On hard floors you’re unlikely to need the extra, because crumbs on tiles don’t take much pulling. Carpet is where suction counts, so the more of it you have, the stronger the Roborock’s case.
Both give you choices about what happens at a carpet edge. The Dreame lifts its pads 10.5 mm, and you can also tell it to leave the pads at the dock, avoid the carpet or raise suction on it. The Roborock lifts its mop too, and in Vacuum Carpet First mode it leaves the mops at the dock before it starts on the carpet.
Underneath, the Dreame has two brushes working as a pair. The Roborock’s side brush extends to reach under kickboards, and its main brush lifts clear on mop-only runs. Both use a front camera to spot clutter.
The mop and the dock
On mopping there’s little between them. Both mop with spinning pads, and both docks empty the bin, wash the pads, dry them, refill the robot and add the detergent. The Dreame washes with water heated to 80°C and the Roborock with water of up to 100°C. The Roborock’s pads press down with up to 14 N, and its dock dries them with air warmed up to 55°C.
For edges, the Dreame swings a pad out by up to 4 cm, and the Roborock has an edge-mopping system for walls and corners. The docks are different shapes: the Dreame’s measures 46 by 34 by 59 cm and the Roborock’s 40 by 49 by 45 cm, so check both against the spot you have in mind.
Battery and price band
The Dreame has a 6,400 mAh battery, as big as any in our list. It runs for up to 220 minutes in quiet mode, covers up to 205 square metres of vacuuming on a charge and recharges in about 4.5 hours.
It also sits in our $1,000 to $1,800 band, and the Roborock is in our top one. The two docks do the same jobs, so the extra band is paying for 3 mm of climb, a centimetre of height and 16,000 Pa of suction. It’s only worth paying if your house needs one of those.

Final thoughts
We'd buy the Dreame X50 Ultra for most houses with awkward sills. It climbs 4.2 cm, it's under 9 cm tall, its dock does every job the Roborock's does, and it sits a price band lower.
The Qrevo Edge 3 Pro wins on three numbers: 3 mm more climb, a centimetre less height and nearly double the suction. If one of those is the exact thing your house needs, a 4.4 cm sill or an 8.5 cm couch gap or thick carpet through the bedrooms, it's worth the extra band. If none of them is, the Dreame does the same jobs from a band down.
