eufy Omni S1 Pro Robot Vacuum & Mop with HydroJet and Auto Washing/Drying Station
Product description
If you’re after a robot that can do both vacuuming and mopping, the eufy Omni S1 Pro is designed around one big idea: keep the mop cleaning itself, while the station handles the messy bits. On paper, it’s built for households that want less day-to-day maintenance from the robot.
That said, it’s still a robot—so it won’t replace deep cleaning when you’ve got a spill disaster. It can be brilliant for regular upkeep, but it depends quite a lot on your floor types and how much dust and hair you’re dealing with.
The essentials
The Omni S1 Pro combines a mop system (HydroJet) with a more hands-off cleaning station. The station’s job is to empty the dust, wash and dry the mop, refill water, collect waste water, and dispense detergent. In other words, the robot is meant to cycle through cleaning more like an automated routine than a “use it, then sort it out yourself” gadget.
For mopping performance, the HydroJet system uses an “Instant Clean Mop” approach with a refreshed mop in real time, plus a downward pressure concept intended to mimic hand scrubbing for stubborn marks. The brand also mentions ozonated water (dual water reservoir loaded with ozonated water) and an Eco-Clean Ozone element in the station—aimed at supporting a cleaner mop cycle.
Key features you’ll actually notice
The station is a big part of the experience. Instead of manually emptying, washing, and drying the mop, the Omni S1 Pro is set up so the dock can handle auto-emptying and auto washing/drying. It also uses a detergent dispenser, which can matter if you want consistent mopping without relying on you to mix or add fluids each time.
On suction, the product description calls out “Incredible potent suction” for deep cleaning on carpets and hard floors, with hair and deep-seated dirt removal in mind. Just keep expectations realistic: the note says actual performance may vary based on floor type and how much dust is present.
Then there’s the obstacle avoidance. The Omni S1 Pro uses 3D MatrixEye with active binocular infrared imaging plus an RGB camera to create real-time 3D models. That’s the sort of feature that can reduce the “bump and get stuck” moments, especially around cluttered rooms or when you’ve got cables and small items on the floor.
What matters most for mopping
If mopping is your main goal, the HydroJet system is the headline. The description focuses on a mop that refreshed itself in real time, alongside downward pressure intended to help with stubborn stains. It’s also worth noting the caution included: eufy says it doesn’t recommend cleaning large amounts of liquid waste due to risk of damaging the robot. So, for everyday mess and routine mopping, it makes sense, for major wet spills, you’ll still want to clean that manually first.
Another practical detail is the “lift mop” idea (lift mop), which is helpful in real-life use when switching between floor surfaces or when you want to reduce unnecessary dragging.

Where it shines, and where it can fall short
This is the type of robot you’ll be happiest with if you want consistent everyday results with minimal intervention. Auto-emptying plus auto washing and drying is a big deal if you don’t want to keep touching dustbags, dirty mop pads, or waste water.
It’s not necessarily the best match if you’re hoping for “set and forget” after heavy incidents. The note about avoiding large amounts of liquid waste is a clear limitation. And because performance can vary with floor type and dirt levels, you may find it’s excellent for maintenance, but it could need help for stubborn, large messes.
Worth considering if your home has both carpets and hard floors, and you want one routine rather than separate tools.
When it makes sense
If your goal is regular whole-home cleaning with mopping built in—especially if you’re tired of emptying, washing, and drying yourself—then the Omni S1 Pro’s dock-led automation is the selling point.
It might not be the right choice if you can’t or don’t want to meet the Wi‑Fi requirement: it needs a router configured to support 2.4GHz (it doesn’t support 5GHz). Also, if you often deal with very wet, liquid-heavy spills, you’ll likely prefer to handle those manually to protect the robot.
Before buying, do a quick reality check on your setup: 2.4GHz availability, your floor mix (carpet and hard floor are mentioned), and whether your “mopping needs” are mostly routine staining and everyday grime rather than large wet waste.
Mini FAQ
Does it wash and dry the mop automatically?
Yes, the station is described as providing auto washing and drying, plus refilling and waste water collection.
What’s the HydroJet system meant to do?
It’s intended to refresh the mop in real time using an Instant Clean Mop approach with a dual water reservoir loaded with ozonated water, and it’s paired with downward pressure for scrubbing-style stain removal.
Is it good for carpets and hard floors?
The description says it’s designed for both carpets and hard floors, but it also notes performance can vary with floor type and dust level.
Does it work with 5GHz Wi‑Fi?
No. The note says it doesn’t support 5GHz and you should use a 2.4GHz router or a dual-band router configured for 2.4GHz.
Final verdict
The eufy Omni S1 Pro looks most compelling if you want automated dock-based maintenance—auto-emptying, auto mop washing/drying, and detergent dispensing—so your weekly cleaning routine stays low effort. It’s a strong “everyday upkeep” proposition, with obstacle avoidance support and a HydroJet mop system aimed at real scrubbing results.
You may want to skip it if you regularly face large liquid spill clean-ups, or if your home can’t provide 2.4GHz connectivity. In a typical UK household with mixed hard floors and carpets, though, it’s easy to see why this kind of station-led robot cleaning is the route people choose when they’re ready to reduce chores rather than add another one.
