Mopping rollers are no longer an exotic premium feature. More and more manufacturers are relying on this technology because it usually works more thoroughly and evenly on hard floors than mop pads. This is precisely where eufy is entering the Omni C28 into the race. The robot vacuum mop does not aim to reinvent the wheel, but to bring modern technology into everyday life at a reasonably affordable price. In the eufy Omni C28 test, we therefore take a closer look at the smart household helper, which aims to impress in many disciplines at the same time. Powerful suction power, modern mopping technology, a well-equipped base station and a convenient app already look promising in the data sheet. In the end, however, it’s not the data sheet that counts, but the question of how well the Robo really works in everyday life.

What’s inside the box
eufy keeps the scope of delivery of the Omni C28 pleasantly clear. The box does not contain half a spare parts store, as is the case with some other robot hoovers.
This is what eufy includes:
- eufy Omni C28 robot hoover
- Omni station including base
- Power cable (connected directly to the station)
- Operating instructions
So everything is on board to get started straight away. Additional extras such as a replacement side brush, a second filter or additional cleaning accessories would of course have been nice, especially as other manufacturers are sometimes a little more generous here. However, we didn’t really miss anything when unpacking. The scope of delivery is not spectacular, but fulfills its purpose without unnecessary ballast.
Design and workmanship: Inconspicuously solid
Visually, the Omni C28 is more of a businesslike, neutral type. eufy dispenses with flashy accents and instead relies on modern, clear lines. The device looks neither playful nor cheap, but simply like a household helper that should blend into the living space and not be misunderstood as a decorative object.
However, with a height of just under 11 cm, the C28 is definitely not one of the flattest models on the market. It can easily fit under many sofas, sideboards or beds, but you shouldn’t expect miracles. If you have very low furniture, you should therefore measure it before buying. In most homes, however, the height will rarely be a real problem.
The view of the underside is particularly interesting. This is where the DuoSpiral brushes are located, which are designed to actively detangle hair and suck it in effortlessly, as well as the extendable CornerRover arm for edges and skirting boards. This may sound a bit like typical marketing wording, but it actually brings tangible benefits in everyday life. Especially in households with long hair or animals, this saves tedious reworking.
The workmanship also leaves a good impression. Nothing rattles, nothing seems wobbly and the station is solid and stable. The closures of the water containers even seem a little too robust at first, if not a little stiff. The Omni C28 is therefore anything but a cheap model, but it is also not part of this high-gloss flagship world in which every fingerprint immediately becomes a medium-sized crisis. And to be honest, that’s rather pleasant here.
Navigation and obstacle detection put to the test
In practice, the Omni C28’s obstacle detection proved to be decent, but not foolproof. eufy relies on its own iPath 2.0 navigation system in combination with LDS and advertises that obstacles as small as 2 x 2 cm are detected. However, this is exactly where the manufacturer’s claim must be classified: Anything smaller than this simply remains a certain risk. eufy itself points out that small objects such as cables or socks can be problematic.
This is exactly what we didn’t just want to believe in the test, we wanted to try it out for ourselves. Shoes and dog toys remained largely untouched, but were occasionally moved a little. Very small things are then quickly dislodged: a hair tie was immediately removed in the test. Loose cables also remain a weak point. The C28 did not reliably detect a cable lying around, but simply dragged it along. The bottom line is that navigation with iPath 2.0 is pleasantly structured in everyday use, but it’s better to tidy up small parts and cables before you start.
Another positive aspect is that the C28 also performs quite well on transitions between hard floors and carpets. It usually negotiates thresholds and smaller edges without too much fuss. Although it doesn’t drive around the house like an off-road rover, it moves pleasantly confidently in normal living environments.
Create a cleaning plan with the eufy app
The eufy app is now one of the more pleasant representatives of its kind, and that doesn’t change with the Omni C28. The setup is absolutely straightforward, maps can also be easily customized and even restricted zones, cleaning schedules or room-based routines can be set up in no time at all. This is exactly what makes the difference in everyday life between an app that just runs along and one that makes the robot really convenient to use.
The app is also pleasantly flexible when it comes to cleaning modes. For example, you can specify whether it should only vacuum, only mop or do both at the same time. There are also various suction and mopping levels as well as carpet rules that can be adjusted in detail. So if you don’t want to intervene manually all the time, you can set up reliable automatic operation in just a few simple steps.
Another positive aspect is that the C28 supports Bluetooth as well as WiFi. Alexa and Google Assistant are also on board. However, you currently have to do without HomeKit or Matter. This is not a problem for everyday use, but for smart home fans with a corresponding focus, it’s something to keep in mind before buying.
eufy Omni C28 test: Impressive suction power
15,000 Pascal sounds like a clear statement on paper. In the end, however, it is not the figure on the data sheet that is decisive, but what the robot vacuum actually gets off the floor in everyday use. In the test, the eufy Omni C28 therefore had to tackle a mixture suitable for everyday use on hard floors: rice, potting soil, a mix of kitchen herbs and a crumbled slice of crispbread – partly in fine and partly in coarser pieces.
Overall, the result was really okay. The C28 followed its path purposefully and collected most of the dirt properly. Rice, potting soil, herbs and even the coarser pieces of crispbread were reliably picked up, with only the very fine crumbs being left behind in places. The Robo did not spread the dirt around unnecessarily, but worked in a pleasantly controlled manner overall. There simply wasn’t much to complain about in the test and after the second pass there was hardly anything left to see.
Things didn’t go perfectly in every corner. After the first pass, some minimal traces remained. But that was really only a little. By the second pass at the latest, everything had been completely removed. All in all, the Omni C28 delivers a convincing suction performance on hard floors, which is absolutely practical in everyday use.
Mopping performance: The advantages of the roller system
As already mentioned, a mopping roller is no longer a sensation. The decisive factor is therefore not the mopping roller itself, but what eufy does with it in practice. And here the Omni C28 delivers a pretty solid result. The roller is continuously supplied with fresh water during cleaning and dirt is removed at the same time. As a result, the mopping result is more even than with many classic pad systems, which tend to slide across the floor and spread the dirt rather than really clean it.
In everyday life, this is particularly noticeable on typical marks in the kitchen, dining area or hallway. Lighter stains, dried splashes and general everyday dirt are reliably picked up. The floor doesn’t just look damp after cleaning, it actually looks clean. This is precisely the point where many cheaper combi Robos fail. In the practical test, the C28 also had to compete against salad dressing and a cola mix. The latter was not a serious problem for the Robo and was picked up cleanly. However, the salad dressing showed that although the eufy works thoroughly, it does so at a very leisurely pace: it approaches the affected area several times, even in reverse. It is easy to see how the pressure of the roller works.
The overall result is quite solid, even if some of the dressing is deposited on the rubber lip of the brush. Less attractive is the fact that the front brushes move through the dirt during this process and partially spread it. It is therefore advisable to clean them afterwards after such use. It’s also a shame that we couldn’t find an option in the app to deactivate the front brushes separately for wiping mode.
On carpets, the C28 lifts its mopping unit to keep the pile dry. This works perfectly in everyday use. Nevertheless, there is still a small catch here: A good mop pad system works a little more consistently on edges and directly along skirting boards in some cases. The eufy’s roller is strong, but not automatically the best solution in every situation – as it does not cover the entire width of the robot hoover.
All-in-one station for dust, fresh and dirty water
The Omni-Station is one of the key selling points of the C28. It automatically empties the dust container, washes the mopping roller, dries it with hot air, refills the robot with fresh water and collects dirty water. It thus relieves the user of a large part of the tedious routine work – and that is exactly what a good station should do in the end.
In everyday use, however, it is noticeable that the tank closures are somewhat stiff. Although they appear robust, they could be a little smoother when regularly removing and refilling.
With 3 liters of dust bag and 2.2 liters each for fresh and dirty water, the station is well dimensioned, although we would like the tanks to be a little larger. However, there is no separate cartridge for cleaning agents. If you want to use a detergent, you have to add it manually when filling the tank.
The station is still compact enough not to immediately dominate half the room as another piece of furniture, but of course it still needs a fixed place in your home – something you should consider before buying.
During operation, the station remains pleasantly in the background, only becoming audibly loud during the extraction process. Although this doesn’t last long, it’s definitely not something you’d want to celebrate right next to the TV or in the bedroom. The other automatic functions are much less noticeable, but still definitely audible.

Alternatives to the eufy Omni C28
If you want to stay within the eufy ecosystem, you should also take a look at the eufy Omni E25. This candidate also offers a mopping roller, but relies on an RGB camera plus LED for obstacle detection and goes one better in terms of suction power. However, the C28 is a more sensible choice for those looking for a good price-performance ratio.
Another interesting alternative is the eufy S1 Pro. However, this is in a completely different price range. Here too, a mopping roller is used, but the device has a flatter design and is even more focused on mopping performance overall. If you want to make as few compromises as possible when it comes to floor cleaning and are not afraid of the extra cost, this is the better overall package. For many households, however, the Omni C28 is probably the more realistic sweet spot.
Anyone looking beyond eufy should take a look at the Roborock Qrevo CurvX. It is significantly flatter, gets under low furniture better and offers a very strong overall package for more demanding living environments. However, it relies on rotating mops instead of a roller and is priced higher than the C28. If you are looking for maximum suitability for everyday use under furniture, you will find a strong alternative here, but you will have to dig deeper into your pocket.
Conclusion: Strong everyday helper with minor weaknesses
The eufy Omni C28 doesn’t want to reinvent the wheel, and that’s not a disadvantage in the end. In the test, it proved to be an overall coherent robot vacuum mop that leaves a really good impression, especially on hard floors. The suction power is good, the mopping roller works solidly in everyday use, the app is pleasantly clear and the Omni station really does take a lot of work off your hands.
However, the overall package is not perfect. Despite iPath 2.0, you still have to make compromises, especially with small objects and loose cables. Even when mopping, it is clear that the roller technology is not automatically superior in every situation, for example directly on edges. Added to this is the rather loud suction at the station, which you don’t need to have right next to you in the living area.
All in all, however, the Omni C28 from eufy is a convincing robot hoover for anyone looking for a modern and convenient cleaning system without immediately having to pay significantly more. It is not a spectacular high-end model, but in everyday use it is a reliable helper with useful features.
