Robot Vacuum and Roller Mop with UniClean Station
eufy Omni S2 Review

30,000Pa suction | 3D MatrixEye 2.0 | HydroJet 2.0 roller mop | 70°C mop wash | Up to 260 min

Overview

The eufy Omni S2 is a robot vacuum and roller mop with 30,000Pa suction and 3D MatrixEye 2.0 obstacle avoidance, which pairs an RGB camera with a 3D dToF sensor. eufy says it recognises more than 200 common obstacles, down to 2.5 cm. The HydroJet 2.0 roller mop presses down with 15N (1.5 kg), turns at 360 RPM and adjusts to stay 5 mm from walls, while two DuoSpiral rolling brushes deal with hair.

The 12-in-1 UniClean station empties the robot into a 2.5L dust bag (eufy quotes up to 68 days between changes), washes the roller with 70°C water, dries it with hot air, adds detergent automatically and uses ozonated water. It has an LCD screen with touch buttons, and the robot carries a fragrance dispenser. The 4,600mAh battery gives up to 260 minutes of vacuuming in quiet mode, and the robot works with Matter, Alexa, Siri and Google Assistant. It crosses single thresholds up to 3.5 cm and double thresholds up to 4.2 cm, lifts its roller 28 mm on carpet, and eufy says its chassis lifts so it can clean shag carpets up to 5 cm.

Pros & Cons

Pros

+ 70°C hot-water roller wash
+ Roller mop presses down with 15N
+ Works with Matter, Alexa, Siri and Google
+ Up to 260 minutes of vacuuming (quiet mode)

Cons

− Tall 670 mm station, and eufy’s diagram shows 1 m of space above it
− Automatic refill and drainage needs the optional Auto Refill and Drainage System bundle
− The manual gives runtimes for vacuum-only mode only

Setup & Installation

Fit the detachable base, then place the station against a wall on a hard, level floor with a strong Wi-Fi signal. eufy asks for at least 1.5 m clear in front and 0.5 m on both sides, and its diagram also shows 1 m above. Fit the screen holder, insert the floor cleaner bottle, then fill the clean water tank to the MAX line with clean water. Remove the foam blocks, fit the fragrance refill and put the robot on the station to charge.

Download the eufy app, tap + and follow the in-app guide. The robot uses 2.4GHz Wi-Fi, so choose your 2.4GHz network. If setup fails, hold the Recharge and Start/Pause buttons together for 3 seconds to reset the Wi-Fi. Once the map is made, avoid moving the station.

Common Problems & Fixes

Running into issues? Our eufy robot vacuum troubleshooting guide covers step-by-step fixes taken from eufy’s own manuals, including won’t connect to Wi-Fi, not charging, mop wash or drying not working.

Who Should Buy It

Anyone who wants a self-rinsing roller mop with a hot-water station, a long vacuum runtime and Matter support.

Verdict

The Omni S2 pairs a 15N roller mop with a 70°C hot-water station and up to 260 minutes of vacuuming. The Omni E35 has more suction (35,000Pa) and a 60°C wash, but neither its UK page nor its manual’s setup steps list Matter.
