Which is better for carpets?

The Dreame X40 Ultra. Its mop lifts 10.5 mm and can detach, and it lists 12,000Pa suction. The Qrevo 2 Pro removes the mop at the dock, which also keeps carpets dry, but its suction is not published.

Which has the better dock?

They solve mopping differently. The Dreame washes the mop and washboard with 158°F water and dries it with hot air. The Roborock physically removes the mop at the dock. Both self-empty and refill.

Is the Qrevo 2 Pro worth the same price as the X40 Ultra?

If owner satisfaction matters most, yes: 4.8 out of 5 from 372 ratings against 4.3 from 76. If you want published suction, runtime and edge reach, the Dreame gives you more to compare.

Which is better for pet hair?

Both are sold for pet homes. The Dreame's 12,000Pa suction and tangle-resistant extendable brush give it the edge on paper; the Roborock's larger, higher-rated owner base is the counterargument.

Which lasts longer per charge?

The Dreame X40 Ultra, at up to 198 minutes from a 6,400mAh battery. Roborock does not publish a runtime for the Qrevo 2 Pro.

Should I wait for a price drop?

The Dreame hit $329.00 on November 1 before returning to $549.99, so its price moves. The Roborock has sat at $549.99 since October 31. Set a price alert on whichever you pick.
