eufy Robot Vacuum Omni C28

Omni C28 brings roller mopping and station automation into another part of eufy’s range. The UK listing describes a HydroJet roller, DuoSpiral brush and five station functions. Its value depends on how much routine floor care it can complete between owner visits to the station. The presence of an Omni name does not make it the same platform as Omni S2.

This guide uses official product material and a dated UK price, not a WCB hands-on test. The Irish model page adds detail about the rinsing system. Those descriptions help identify the mechanism, but a buyer should still inspect the dried floor, roller condition and missed areas after a representative job. A water-rinsed roller is a design choice, not a guarantee of a particular finish.

The useful demonstration includes a normal hard-floor route with a few recurring dirty patches. Observe whether the robot returns for washing at sensible intervals and whether those visits interrupt the job. A kitchen-only run and a whole-home session can produce very different water use. Plan around the station’s clean-water supply and the owner’s willingness to empty used water.

Runtime needs the same care. The published combined vacuum-and-mop duration is shorter than the vacuum-only figure. Compare the mode you intend to schedule, including carpets, turns and repeated treatment. A large maximum for a dry route should not be used to promise that a similarly timed wet route will finish without charging or station visits.

C28’s cited specification uses LDS and laser-line sensing. Do not assume it carries Omni S2’s camera hardware or recognizes the same objects. Test a representative chair group, doorway and low-furniture route, while removing cords and items that should not be left for any robot to negotiate. Look for repeatable coverage rather than one successful obstacle demonstration.

The 4.35-inch height and 0.79-inch crossing claim are starting points for measuring the home. Leave a clearance margin under furniture and check the shape of raised transitions. A rounded threshold approached straight on is different from a sharp track at an angle. For multiple levels, plan manual carrying and continued access to the station for roller preparation, washing and charging.

Five maps still require station access

The C28 multi-floor support note confirms up to five stored maps. On a floor without the station, the app can request mop washing before a wet task. It describes a prompt when more than ten minutes have elapsed since the last mop wash, or more than three minutes of mopping have occurred since that wash. Follow the current app prompt, since firmware can change the sequence.

The owner can return C28 for washing or continue with vacuuming only. An empty onboard clean-water tank or full dirty-water tank also changes the task to vacuum-only. After cleaning, C28 returns to its starting position and needs carrying back for self-cleaning. Consider that routine before buying one robot for several levels.

C28 belongs on a shortlist for routine roller-mop cleaning with a checked UK offer. Compare T80S OMNI and Qrevo Curv 2 Flow on finished-floor results, route completion and maintenance. Choose the product whose exact sensing hardware and station routine fit the home. Keep the operating mode, country and package attached to every endurance or price comparison.

The GBP 649 reference belongs to the selected UK listing on September 12, 2026. It is not a currency-converted comparison with a US ECOVACS offer. Recheck delivery, local warranty and included consumables in the country of use. Keep the C28 model code on the order because neighboring eufy products can share similar station imagery.

The official FAQ describes manually mixing approved solution at 1:200. That instruction matters when comparing automation: refill and roller washing do not automatically imply detergent dosing. Confirm the supplied manual before using any fluid. Regional package differences should be resolved through exact contents and instructions, not an assumption based on a general Omni promotion.
