eufy Omni S1 Pro Review: Roller Mop Tech That Actually Works

Most robot vacuums mop by dragging a damp pad. The eufy Omni S1 Pro mops with a spinning roller that scrubs the floor like a proper floor cleaner, then washes itself in the dock. For hard-floor homes where mopping matters more than vacuuming, this is one of the most compelling robots of 2026.

What I like

The HydroJet roller is the headline. Instead of smearing dirt around with a pad, the roller scrubs, squeegees and self-cleans continuously, so you get genuinely cleaner hard floors. The 10-in-1 dock handles emptying, washing, drying and ozone cleaning, keeping maintenance close to zero. Stubborn stains get real pressure — it’s closer to a dedicated floor washer than a typical robot mop.

What could be better

Vacuuming is solid but not class-leading; homes with heavy carpet should look at suction-first flagships. The roller also needs occasional cleaning and the dock takes more floor space than smaller stations.

Pros & cons

Pros: best-in-class mopping; ozone cleaning; very low maintenance; 8,000 Pa suction is plenty for hard floors.

Cons: carpet performance is average; dock footprint is large; consumables cost more over time.

Who should buy it

Hardwood, tile or vinyl homes where mopping is the priority. If you’re mostly carpet, pick a suction-first model instead.

FAQ

Is the ozone cleaning safe? Yes — it works inside the sealed station to sanitize the roller and tank.

Does it avoid obstacles? The 3D Matrix Eye handles common obstacles like furniture and pet bowls well, though cables are still the weak spot for every robot.
