Product description
The essentials
If you want an all-in-one robot that can vacuum and mop as part of the same routine, the eufy E28 Omni is built around that idea. It combines a mop with a vacuum system, and it’s paired with an all-in-one station that handles the messier side of robot cleaning (emptying dust and taking care of the mop pads).
On paper it’s aimed at households that deal with mixed flooring — carpets and hard floors — and want more than basic surface mopping. There are also a couple of design choices that focus on real-world annoyance, like reducing tangles around the brushes and pushing the cleaning into corners and edges.
That said, it’s still a robot. If your carpets are very delicate or you’re after a “deep clean every day” level of manual scrubbing, you may find it falls short in stubborn, set-in messes — but it’s designed to get a lot of the heavy lifting done routinely.
What it does well (and what you’ll notice)
The standout theme here is deep cleaning, supported by two things: suction performance and a mop system that actively cleans the mop.
For vacuuming, the E28 is specified with 20,000 Pa turbo suction, which should help when you’re pulling dust and hair from carpets and hard floors. The brand also positions it for “one pass” carpet cleaning of hair and dust that sits deeper in the pile.
For mopping, it uses the HydroJet System. The key point isn’t just that it mops — it cleans the mop while you’re using it, with the mop cleaning described as happening 360 times per minute. There’s also a specified downward pressure of 1.5KG to help lift and shift stubborn marks rather than just smearing them.
Where this can feel genuinely practical is the day-to-day rhythm: you can run vacuum + mop without needing to think about cleaning the mop pad yourself every time. If you’ve ever had that “robot mopped, but it smells” situation, the design here tries to tackle that by washing mop pads and then drying them with heated air (35–50°C) to help prevent bad odours and bacterial growth.
Key features that help with the hard bits
Robots usually struggle in the places you’re probably thinking about most: edges, corners, and hair tangles.
The E28 uses an “auto-tangling” strategy via DuoSpiral Brushes, which are designed to prevent hair entanglement and reduce how often you need to maintain the brush. It’s not the same as never needing maintenance, but it can take the sting out of long-haired households.
For edges and corners, the CornerRover Arm is described as tackling hard-to-reach areas, increasing overall cleaning coverage by 20% and providing 100% edge coverage (based on testing in eufy’s laboratory). That kind of claim is always best taken as “optimised on their setup”, but the intent is clear: to reduce the strip of floor you’d normally have to tidy up with a handheld.
And yes, it’s meant to be an all-in-one setup with the Omni station. The dust bin empties into a 3L dust bag, which only needs replacing every 75 days (again, based on the stated design), and it also supports clean-water handling via a 2.5L clean water tank.
Tech specs that matter for buying decisions
Here are the specifications and constraints you should actually care about before you buy:
- 3-in-1 robot vacuum + mop + portable deep cleaner design
- HydroJet System mop cleaning rate: 360 times per minute
- Downward pressure for mopping: 1.5KG
- Suction: 20,000 Pa turbo
- Mop cleaning and drying approach: mop pads washed with clean water, then dried using 35–50°C heated air
- Clean water tank: 2.5L (stated for mopping a 180 sq m home 4 times)
- Dust bag capacity: 3L (replacement every 75 days is stated)
- Wi-Fi support: only 2.4GHz (5GHz Wi‑Fi is not supported)
Note that the Wi‑Fi limitation is easy to overlook and can matter if your home network uses 5GHz only.
Who it suits best (and who should be cautious)
It makes sense if you want a single robot to handle the full routine across different surfaces — particularly if you’ve got carpets plus hard flooring, and you prefer automation that doesn’t leave you cleaning the mop pads constantly.
It’s also worth considering if hair is an issue. The combination of DuoSpiral Brushes (tangle reduction) and strong suction is designed for that day-to-day shedding problem.
It might not be a great match if your priority is ultimate, spot-by-spot carpet stain removal in the “scrub it properly” sense. The unit is positioned for deep cleaning and tough stain help via mop pressure and an active HydroJet approach, but robots generally can’t replace hands-on treatment for very stubborn marks.
You may want to skip it if your Wi‑Fi setup doesn’t include 2.4GHz access, because 5GHz isn’t supported.
Tips for getting the most from it
A simple approach works best: set it up for mixed floors, run vacuum and mop as part of your regular cleaning, and treat the station as part of the system.
A practical example: suppose you’ve got a hallway with hard floors and a lounge with carpet. Run the robot through the hallway first as part of the same cycle, then let it mop the hard floor and vacuum the carpet in one routine. The HydroJet cleaning step matters most when the mop pad would otherwise start to wear, and the heated-dry process is there to reduce the “damp pad” problem.
Finally, keep an eye on the dust bag replacement interval in real use. The stated frequency is useful, but households vary.
Final verdict
So, is the eufy E28 Omni worth buying? It’s a strong choice if you want a vacuum + mop robot that aims to reduce the usual friction points: mop hygiene (washed and heated-dried), hair tangling (DuoSpiral Brushes), and better coverage near edges and corners.
You should think twice if you only have 5GHz Wi‑Fi available, or if you expect robot mopping to replace deep manual stain work on heavily soiled carpets. For most everyday cleaning needs across carpets and hard floors, though, the overall all-in-one approach is exactly the kind of system that can save time without turning your home cleaning into another chore.
Mini FAQ
Does the E28 support both 2.4GHz and 5GHz Wi‑Fi?
No. It only supports 2.4GHz Wi‑Fi, and 5GHz is not supported.
How does the HydroJet System help with mopping?
The system cleans the mop very frequently (360 times per minute, as stated) and uses downward pressure (1.5KG) to support deeper cleaning rather than just spreading moisture.
Will it completely prevent hair tangles?
It’s designed to prevent hair entanglement via DuoSpiral Brushes and reduce maintenance frequency, but any robot brush can still need some attention over time.
How often do you replace the dust bag?
The station empties into a 3L dust bag, with replacement stated every 75 days, depending on how your household runs the unit.
