A powerful vacuum cleaner with a clever roller for mopping
Quite different to most of the competition, the Eufy Omni E25 uses a roller for mopping, adding clean water and scraping dirt off into a separate tank. That means the roller is always clean and fewer visits are required for the dock. Mopping is largely excellent, bar dealing with the toughest of stains, and overall vacuuming performance is up there with the best.
The downside of the roller is that it can’t be left behind to allow the robot to deal with deeper pile carpets. Still, for the right balance of price, performance and features, the Eufy Omni E25 is a great choice.

Introduction
Eufy was the first company to introduce a robot with a roller, rather than microfibre pads, for mopping with the excellent if not expensive Eufy Omni S1 Pro. With more companies starting to follow suit, the company is back with a slightly cheaper roller-based robot, the Eufy Omni E25.
A very powerful robot and a decent mopper, the Eufy Omni E25 offers good all-round cleaning at a price that’s a bit easier to swallow compared to the main flagship models. It does lack some of its rivals’ more advanced features, however, and doesn’t have as flexible settings for dealing with carpets.
Design and features
- Roller uses clean water for mopping
- AI obstacle avoidance
- Self-cleaning and self-emptying
While most robot vacuum cleaners and mops use a vibrating microfibre pad (the Roborock Saros 10, for example) or dual spinning microfibre mops (the Dreame X50 Ultra Complete, for example), Eufy was the first company to introduce a robot that used a self-cleaning roller with the Eufy Omni S1 Pro.
A very similar system is used here with the Eufy Omni E25, with a roller that stretches almost edge-to-edge. There is a small gap on either edge, which means that this robot can’t clean right to the edges, as with rivals that have either swing-out mops or dedicated edge mops.
Using a roller has its advantages and disadvantages. Unlike any kind of mopping pad, a roller is self-cleaning. Using a HydroJet system, the Eufy Omni E25 cleans the mop with fresh water.
A downward force of 1.5kg ensures good contact with the floor, with the roller picking up stains and dirt, which are scraped off and deposited in a dirty tank. That means that only a clean roller makes contact with the ground, and the robot doesn’t have to stop and pause cleaning to wash its mopping pads.
The flip side of this system is that while the roller can be lifted off the ground to avoid soaking carpets, this system only really works with short-pile carpets. If you’ve got carpets with longer fibres, then the Eufy Omni E25 can wet them.
Look at the flagship competition, such as the Dreame X50 Ultra Complete or the Roborock Saros 10, and these models can lift their mop cloths higher and even completely detach them for a risk-free vacuum-only experience.
Ultimately, the mix of flooring types you have is likely to play a big part in choosing the right robot for you.
Aside from the roller, the Eufy Omni E25 is much like any other robot vacuum cleaner, although there are a couple of nice touches.
Rather than a single brushbar for agitating dirt, the robot has a split DuoSpiral Brushes. These are designed to funnel hair into the main suction path and, once the robot docks, the brushes retract and spin in opposite directions, funnelling any trapped hair into a dedicated compartment.
There are two edge brushes on this robot, one of which is CornerRover arm, which can swing out to get right to the edges or corners of rooms.
On top sits the LiDAR dome, which the robot uses for navigation and mapping. This dome can’t be retracted into the robot’s body, so the Eufy Omni E25 is unable to squeeze under many low bits of furniture, such as sofas and sideboards.
Aiding navigation are the AI-powered cameras at the front, which are designed to spot and avoid common obstacles, such as shoes and pet mess.
There’s a typical dock provided with this robot vacuum cleaner, which takes 3-litre dust bags for the auto-emptying system. According to Eufy, this holds enough dust for 75 days of use, before you whip it out and replace it with a fresh one.
Two 2.5-litre water tanks are provided: one for fresh water and one for dirty water.
Behind the clean water tank sits the slot for Eufy’s detergent. This is provided in a non-refillable bottle, so once the detergent has run out, you need to replace it with a fresh one and recycle the old one.
As is typical for this kind of dock, it gives the roller a deep clean when the robot docks, and then dries it with 50°C air, to prevent bacteria and mould growth, and suppress smells.
Control of the robot is via the EufyClean app. It’s functional and simple to use, and begins by getting the Eufy Omni E25 to perform a mapping run, at the end of which a 3D map is generated of your home.
In my case, running the robot around the Trusted Reviews Home Technology Lab, I found that the map was overly complicated, with more rooms put in than there are. You might have more luck in your own home.
Fortunately, it’s simple to merge and split rooms, and to rename. And, I switched to the 2D map view, which I find easier to read. It’s possible to manually place furniture in rooms, too, which acts as a quick-select zone for cleaning up, such as vacuuming around a dining table at the end of dinner.
Cleaning can be performed for the entire home, a room or a zone. There’s an AI Automation option, where the Eufy Omni E25 will pick the cleaning settings for a room, but it’s easy to override.
There’s an option to vacuum only or to vacuum and mop, but not to mop only, nor is there a direct option to vacuum first and mop second. Again, with the slightly limited carpet avoidance settings (due to the roller not being removable, and only lifting), this feels more like a robot that’s better suited for homes with hard floors and some short-pile carpet or area rugs.
For the cleaning modes, there are three suction powers (plus an option to boost suction on carpet), three water level modes, a choice of two cleaning intensities (standard or deep), and a choice of one or two passes. That covers all of the basics.
Performance
- Very powerful vacuuming
- Good battery life
- Powerful mopping on all but the toughest of stains
I set the Eufy Omni E25 out and about cleaning the lab, watching how it navigated, after leaving some items scattered around the floor, including fake pet mess, cables and a shoe.
For the most part, the AI object detection works very well, with the Eufy Omni E25 able to skirt around problems for the most part. There are some times when the vacuum will hit something, particularly if the E25 turns into an obstacle next to it, but for the most part, it does a great job of avoiding problems and going where it should.
To see how well it vacuumed, I set out my usual messes, starting with flour on the test carpet. With a rated suction of 20,000Pa, the Eufy Omni E25 is up there with the flagship models, and it shows.
Set to two passes on maximum power, the robot managed to clean up the vast majority of the mess, with just a small trace of dust left that you can see in the after image below.
I added flour to the hard floor, and this was all picked up with ease, as I’d expect from a robot this powerful.
Moving to the edge test, I added flour to the floor next to the kitchen plinth. The Eufy Omni E25 did a good job, getting close and removing the main part of the spill, although there was a thin trace of dust left behind.
I then moved on to the mopping tests, with the Eufy Omni E25 set to maximum water flow. The easier stains were removed easily enough, with my dried-on coffee stain mostly gone in two passes, with just a faint outline left behind (a subsequent pass did remove the mess).
My red wine stain was completely removed in two passes, with no stain left behind.
My dried-on mud stain has both solid particles and the liquid stain. The particles were vacuumed up, and two passes with the roller was all that was required to remove the rest of the stain.
My toughest test is dried-on ketchup. Two passes diminished the stain, but it was still highly visible.
I tried two more passes, but the ketchup was still firmly stuck to the floor. I then tried spraying the stain with some regular cleaner to give it a head start. After two more passes, the stain was smaller, but still visible.
I found that the Dreame X50 Ultra Complete and the Roborock Saros S10 did a better overall job on this stain, although both devices are a lot more expensive and can use hot water.
I measured the Eufy Omni E25 at a reasonable 59.3dB, which is loud enough to hear, but not much louder than a fan on its turbo mode. In other words, you can easily run this robot vacuum cleaner while being in the same room.
Battery life is rated for 125 minutes for vacuuming and mopping on the lower power setting, but I found that battery life was good using maximum power. Running in this mode, the robot managed two passes of the Home Technology Lab, which has a total floor area around the same size as the floor of an average home.
Should you buy it?
Buy if you want a powerful robot vacuum cleaner with some high-end features
Excellent suction power and great navigation at a sensible price, this roller-powered robot vac and mop cleans hard floors well.
Don’t buy if you have a lot of carpet mixed with hard floor
To cope with all environments to the best, you may prefer a robot that can drop its mop off at the dock.
Final Thoughts
With this robot vacuum cleaner, you don’t get the more advanced features you get on some of the flagships, such as a chassis that climbs stairs, or a retracting LiDAR sensor. And, on the toughest floor stains, the Eufy Omni E25 wasn’t quite as good as the best competition.
But, the Eufy Omni E25 is a lot cheaper than the flagships, and it’s a very powerful vacuum cleaner. For most types of floor stains, the self-cleaning roller works really well, and the robot doesn’t need to return to the dock often to clean itself.
However, the roller can only lift a little way off the floor and can’t be removed by the dock, so those with mixed flooring types may prefer a more flexible model that can drop its mop pads. For those with mostly hard floors, this robot is brilliantly priced for what it does.
