eufy Omni S1 Pro Review (UK): The Robot That Really Mops
Quick verdict
If your home is mostly hard floors and you want a robot that genuinely scrubs rather than just wipes, the eufy Omni S1 Pro is one of the most capable all-in-one cleaners you can buy. Carpet-heavy homes should look elsewhere.
Check current price on Amazon UKMost robot mops drag a damp pad around and call it cleaning. The eufy Omni S1 Pro takes a different approach: it uses a full-width roller mop that is constantly rinsed with clean water while it cleans, more like a cordless hard-floor washer than a typical robot. Add 8,000 Pa of suction and a base station that does almost all the upkeep for you, and you have one of the most hands-off cleaners on Amazon UK.
Who is it for?
The S1 Pro makes the most sense for busy households with kitchens, hallways and living areas laid with tile, laminate, vinyl or wood, especially homes with kids or pets where sticky spills and muddy footprints are a daily thing. It also suits anyone who hates maintenance, because the station takes care of emptying, mop washing and refilling. If your home is mostly thick carpet, a vacuum-first robot will serve you better and cost less.

Mopping: the headline feature
This is where the S1 Pro stands out. The roller spins at up to 170 RPM while pressing down with 1 kg of force, and because it is rinsed with fresh water as it goes, it isn't just spreading dirty water around the room. UK reviewers at TechRadar and Trusted Reviews both called the mopping outstanding, and US testers at Vacuum Wars found it excellent on dried-on stains and large wet spills, without leaving streaks.
Vacuuming and navigation
Suction is strong by robot standards: the Turbo setting leaves visible lines on carpet. LiDAR mapping is quick and accurate, you can set cleaning modes room by room (for example a deeper mop in the kitchen than in the hallway), and obstacle avoidance means fewer rescues from cables and socks. The weak spot is deep carpet cleaning. In Vacuum Wars' embedded-dirt test it scored among the lowest results they have recorded, even though it clears surface debris and small rugs well.

UK price
The S1 Pro launched in 2024 at a UK list price of £1,499, according to TechRadar and Tech Advisor. Amazon UK prices for robot vacuums change often, and big discounts are common around Prime Day and Black Friday, so check the current price on Amazon UK before you buy.
Verdict
The eufy Omni S1 Pro is the robot to pick if clean hard floors are your priority. Its rinsing roller mop beats spinning and vibrating pads, the station makes it close to maintenance-free, and the app is easy to use. It loses a star for so-so deep carpet cleaning and its edge reach. For tile, laminate and wood floors, though, it is one of the best all-in-one robots available on Amazon UK.
FAQs
Is the eufy Omni S1 Pro good on carpet?
It handles everyday surface debris and rugs well, and lifts its mop by 12 mm over carpet. But independent testing found its deep cleaning on thicker carpet weaker than rivals, so it is best for homes that are mostly hard floors.
Does the eufy Omni S1 Pro empty itself?
Yes. The UniClean station empties the dust bin into a 2.5-litre bag, refills the robot's water tank with cleaning solution, and washes and dries the roller mop.
How much does the eufy Omni S1 Pro cost in the UK?
It launched in 2024 with a UK list price of £1,499. Prices on Amazon UK change often, so check the current price on Amazon before you buy.
