Which is better for pet hair?

Both use dual anti-tangle brushes. The CurvX has more suction at 22,000 Pa, which helps on carpet. The S5V at 12,000 Pa is enough for hard floors and is far cheaper.

Is the CurvX worth the extra money?

Only if you need its extras: hot water mop washing, dustbin emptying, water refill, a 3.14 in profile and AdaptiLift. For hard floors and a tight budget, the S5V covers the basics for much less.

Which fits under low furniture?

The CurvX, at 3.14 in with a retractable LiDAR tower. The S5V is 3.80 in tall, so measure your sofa and bed clearance before buying it.

Which has better reviews?

The S5V: 4.5 of 5 from 977 ratings. The CurvX has 3.4 of 5 from just 16 ratings, which is a small sample.

Do both wash their own mops?

Yes. The S5V self-washes and dries its mop. The CurvX goes further with hot water washing, mop drying, dock self-cleaning, dustbin emptying and water refilling.

The S5V at 36.16 lb total versus 47 lb for the CurvX. That matters if you carry the dock up stairs.

Roborock Qrevo S5V Robot Vacuum vs Roborock Qrevo CurvX Robot Vacuum

Buy the Qrevo S5V if you want strong suction and a self-washing mop for a few hundred dollars. Buy the Qrevo CurvX if you need deep carpet cleaning, a low profile under furniture, and a dock that washes with hot water and refills itself. The gap is huge: the S5V hit $200.00 on November 3, 2026, while the CurvX is $1,370.60 at eBay as of November 7, 2026. The CurvX has a much higher list position and a thin review base of 16 ratings at 3.4, so the S5V is the safer value.
