eufy Robot Vacuum Omni S1 Pro: Specs, Features, Pros & Cons

Editor’s note

The Omni S1 Pro runs for 216 minutes in standard mode — 277 in quiet mode, longer than anything else here — and it does it at under 60 dB.

Those two numbers work together. A machine that cleans for four and a half hours on one charge finishes a large home in a single pass rather than stopping to recharge halfway; a machine that does it quietly can run while you are in the house rather than only when you are out. Most robots here sit around 65 dB with shorter runs.

The mop is a roller rather than spinning pads, applying continuous pressure across its width and presenting a clean surface as it turns, which handles dried marks better than a dragged pad. It lifts 12 mm for carpet, the dock washes it and dispenses detergent automatically, and the pads are removable for hand washing.

Navigation is LiDAR with obstacle avoidance and mapping, so it works as well at night as during the day. At 96 mm it clears more furniture than the 105 mm machines, and the water tank holds 240 ml with a 250 ml bin.

Suction is 8,000 Pa, which is mid-range against the 18,000 to 22,000 Pa flagships here — adequate for hard floors and low-pile carpet, not for deep rugs.

Buy it for a large home where the machine needs to run long and quietly, on mostly hard floors. Buy a higher-suction model if carpet and pet hair are the problem.
