Eufy Omni S1 Pro

The Omni S1 Pro was eufy's swing at the flagship tier, and the thing everyone talks about is the roller mop. Instead of dragging two spinning pads of increasingly dirty water around, it runs a self-rinsing roller with real downward pressure — and owners on hard floors say the results embarrass pad-style robots. Owner sentiment sits around 68% positive: people with hardwood or tile love it, and the loudest complaints come from everyone else.

In practice it's a mopping-first machine. Suction measures well above average and hard-floor debris pickup is strong, but carpet deep cleaning scored near the bottom of Vacuum Wars' test group, and it can strand itself on longer-pile rugs. The UniClean dock does everything — auto-empty (rated for about 65 days), mop washing and drying, water refill, plus an ozone sterilization cycle that actually keeps the station from stinking. The app is well regarded, though owners report enough software glitches — skipped schedules, random errors — that 'reliable but occasionally flaky' is the fair description. Budget for eufy's proprietary detergent, and know that the dirty water tank is a chore to clean.

This is the robot for all-hard-floor homes that care about mopping above everything. At its frequent $650-800 sale prices it undercuts the Roborock S8 MaxV Ultra and Dreame X40 Ultra by hundreds while out-mopping both. But if your home is more than incidentally carpeted, buy something else — and note that by 2026 standards the roller-mop crown has moved on to newer machines like the Narwal Flow, so this is a value pick, not the state of the art.
