Robot Vacuum and Rolling Mop with UniClean Station
eufy Omni S1 Pro Review

8,000Pa suction | 3D MatrixEye avoidance | Always Clean rolling mop | Ozone water | Up to 277 min

Overview

The eufy Omni S1 Pro is a robot vacuum with an Always Clean rolling mop, 8,000Pa suction, dToF LiDAR navigation and 3D MatrixEye obstacle avoidance. eufy’s UK chooser lists 1 kg of mop pressure, 170 RPM and a 12 mm mop lift for carpet, and the manual says it lifts the mop automatically when it detects carpet.

The 10-in-1 UniClean station dampens the mop before a clean, can rinse it during a clean, then empties the robot into a 2.5L dust bag, washes the mop and dries it. It makes ozone water for washing, has an LCD screen with Recharge, Start/Pause and mode buttons, and can drain itself for transport. The 4,600mAh battery runs for up to 277 minutes vacuuming or 184 minutes vacuuming and mopping, and the robot works with Alexa and Google Home.

Setup & Installation

Remove the stickers and foam, fit the side brushes marked 1 (red) and 2 (grey), then connect the power cord under the station’s cord cover. Place the station on a hard, level floor against a wall, out of direct sunlight, with at least 1.5 m clear in front and 0.5 m at the sides and a strong 2.4GHz Wi-Fi signal. Fit the hard floor cleaner cartridge and fill the clean water tank with tap water (eufy recommends tap water rather than distilled or mineral water).

Open the robot’s magnetic cover, switch the power switch to I, then download the eufy Clean app and scan the QR code on the robot. To add it, press the red Reset button under the cover once; when you hear “Wi-Fi has been reset”, follow the in-app steps and choose your 2.4GHz network.
