Is the Roborock Saros 20 Flow worth it?
Yes — if you want one robot that does it all.
It pairs 36,000 Pa of suction and tangle-free brushes with a roller mop that's rinsed with hot water as it goes, which testers found lifts sticky and dried stains better than spinning pads. A lifting arm climbs double thresholds up to 8.8 cm. It costs flagship money, and edges and corners aren't perfect.

Get it if…
- You want the best mopping a Roborock does.
- You have pets and want hair not to wrap the brush.
- Your home has high thresholds or step-ups between rooms.
Skip it if…
- You're on a budget — the D30 Ultra covers the basics for far less.
- Your floors are mostly carpet — mopping is the main reason to pay this much.
How we reached this verdict
EFTM called it the best all-rounder it has tested, with the roller mop lifting jam and dried spills that beat older Roborock pads. House Digest gave it 9/10 for suction, mopping and a tangle-free brush, and Fnac's testers measured it clearing a 5 cm threshold. The catches are the price, imperfect corners and an app that could be clearer.
We compared independent expert reviews with the manufacturer's specifications, then checked it's sold at a major retailer where you live. We don't test products ourselves.
