Buy on Amazon USA
It nearly triples the 20,000 Pa of the Qrevo Curv 2 Flow, ships with Matter, Apple Home, SmartThings and Home Assistant working, and measures 89.8 mm tall so it slips under low furniture, while its dock empties, washes, dries and doses detergent on its own. The Roborock Qrevo Curv 2 Flow is the cheaper robot and rinses its roller mop in real time, but it lists Matter and Apple Home as a future update rather than a working feature, and it runs up to 242 minutes against the Saros's 301. Buy the Roborock Saros 20 Flow for maximum suction and working platform support, and the Roborock Qrevo Curv 2 Flow if the lower price and the self-rinsing roller come first.

What the differences mean

Runtime

The Roborock Saros 20 Flow is rated for up to 301 minutes against 242 for the Roborock Qrevo Curv 2 Flow, so it runs about an hour longer on a single charge.

Mop system

The Roborock Qrevo Curv 2 Flow rinses its roller continuously while it cleans. The Roborock Saros 20 Flow empties, washes and dries its mop and dispenses detergent at the dock, which is the more automated routine.

Which one to buy if

What owners say

Owners of the Roborock Qrevo Curv 2 Flow praise how little attention it needs: daily runs for weeks without a rescue, LiDAR mapping that holds up, and a roller mop rinsed with clean water and scraped as it works, so grime is not smeared around. Pet households repeatedly say the dual anti-tangle brush handles hair the way the marketing promises, and the app earns credit for per-room routines and automatic carpet boost. The honest weak spots are edges, where it does not hug baseboards or reach under low cabinet kicks, and a minority report streaking on hardwood. The roller, scraper and dirty-water tank still need periodic manual cleaning.
