Eufy C28 Robot Vacuum & Mop Review: Powerful Mopping, Smart Navigation, and Great Value

Today we’re taking a closer look at the Eufy C28 robot vacuum and mop, the younger sibling to the E25 and E28. Eufy provided this unit for testing, but this review is not sponsored, and all opinions are based entirely on our own hands-on experience and testing.

The C28 marks our 15th Eufy robot vacuum tested and more than 135 robot vacuums reviewed overall. After spending significant time with it in a busy household environment, it’s clear the C28 is designed to bring premium-style roller mopping and strong pet-hair handling to a more affordable mid-range price point.

Unboxing and Setup

Inside the box, you get the robot vacuum itself, the charging and cleaning station, a ramp attachment, power cord, one pre-installed vacuum bag, and the usual documentation. Eufy keeps the setup process refreshingly simple. Once the ramp is attached and the clean water tank is filled, the robot is ready to charge and begin mapping and cleaning.

One thing worth mentioning is that no extra replacement bags are included in the package, which is becoming more common but is still a little disappointing at this price point.

Cleaning Performance

After our first few cleaning runs, the C28 immediately felt very similar to the E25 in terms of overall cleaning behavior, which is definitely a good thing. In our home, which includes five people, three with long hair, along with a long-haired dog, the robot had no trouble handling everyday debris like crumbs, dust, dirt, and pet hair.

One of the standout features is Eufy’s Duo Spiral anti-tangle brush design. We’ve mentioned in previous reviews that this style of brush system works particularly well for homes with pets or long hair, and the C28 continued that trend. Hair buildup on the roller was minimal overall, especially considering how much hair the robot collected during testing. Some strands can still collect near the brush edges compared to certain conical roller systems, but it was far less noticeable than with older brush designs.

We do wish the C28 included an extending side brush for better edge reach, but the robot still performs reasonably well along walls thanks to its dual side brushes and slightly squarer body design.

Roller Mopping Performance

Mopping is likely the biggest reason someone would choose the C28 over many competing models in this price range. Eufy uses a very large roller mop here, measuring over an inch longer than the average roller mop system we’ve tested. That extra width helps the robot maintain strong floor coverage and consistent cleaning results across hard floors.

In our testing, the C28 performed especially well on LVP flooring. Floors looked noticeably cleaner after runs, and the roller maintained solid contact with the floor throughout the cleaning cycle. The dock also handles automatic mop washing and drying, which significantly reduces the amount of manual maintenance required.

That said, there are still a few premium features missing. The station does not support hot water mop washing or automatic detergent dispensing, both of which are becoming more common on higher-end models. We’d also still like to see a true mop extension feature added in future versions to improve edge and corner coverage.

Another nice touch is the removable onboard dirty water tank, which is simple to access and clean when needed.

Carpet Cleaning and Suction Performance

On paper, the C28 looks extremely impressive with its advertised 15,000Pa suction rating, which is considerably higher than the category average. However, real-world testing showed more mixed results depending on the type of debris and surface being cleaned.

In airflow testing, the C28 performed almost exactly average, though airflow volume itself was actually above average. Pressure testing was less impressive, suggesting that the robot’s raw suction numbers don’t necessarily translate directly into stronger deep-cleaning pressure.

Still, the real-world cleaning results were surprisingly strong in some situations. In our coffee deep-clean carpet test, the C28 scored 95%, which was not only above average but also significantly better than the E25’s previous result. Larger debris pickup on carpet was generally very good overall.

Where the robot struggled more was with extremely fine debris. Sand pickup performance was below average, while cat litter pickup was much closer to expected category performance. In practical day-to-day use, this means the C28 tends to perform better with larger debris and pet messes than ultra-fine particles embedded deep into carpet fibers.

Obstacle Avoidance

Obstacle avoidance turned out to be another strong area for the C28. The robot scored well above category average during our testing, successfully avoiding many common household hazards.

Like most robot vacuums, carpet surfaces proved more challenging than hard floors. The C28 occasionally contacted larger objects like toy trucks or dog bones, but it handled more difficult hazards like USB cables and simulated pet waste surprisingly well for a robot in this price range.

While it still isn’t perfect, Eufy’s obstacle avoidance system has improved considerably compared to earlier generations.

Battery Life and Coverage

Battery performance is one area where the C28 was less impressive in real-world testing. Eufy advertises up to 251 minutes of runtime from the 5,200mAh battery, but actual coverage results fell below average in both our best-case and worst-case testing scenarios.

Compared to the E25, the C28 covered noticeably less area before needing to recharge. For smaller and medium-sized homes this likely won’t be a major issue, but users with very large floorplans may notice the difference.

App Experience and Features

The Eufy Clean app remains straightforward and easy to use. Navigation is clean and intuitive, making it simple to set up room cleaning, zone cleaning, whole-home cleaning, no-go zones, virtual walls, and multi-floor maps.

The app also includes adjustable suction and mop settings, manual controls, BoostIQ automation, off-peak charging, and access to experimental features through Eufy Lab.

One feature we still wish Eufy would add, however, is a true mop-only mode. It’s something we’ve requested repeatedly because it would make roller-mop robots like the C28 even more versatile for hard-floor cleaning.

Comparisons and Community Questions

After publishing our initial impressions, we invited Reddit users to submit questions and comparison requests. One of the most common questions was how the C28 compares to the E25.

At the time of testing, both models were selling for very similar prices. In that situation, the E25 is probably still the better overall buy thanks to its side-brush extension, automatic detergent dispensing, and slightly better obstacle avoidance. However, if the C28 receives deeper discounts, it becomes a far more compelling value option.

We were also asked how it compares to premium models like the MOVA Z60 and Roborock Curve 2 Flow. Considering the MOVA Z60 costs dramatically more, the C28 actually holds up surprisingly well in day-to-day cleaning performance. The flagship models still offer more advanced features and refinements, but the C28 delivers strong value for the money.

Compared to the Roborock Curve 2 Flow, the feature sets are fairly similar overall. Much of the decision may ultimately come down to app preference and ecosystem familiarity.

Maintenance

Maintenance on the C28 is relatively straightforward. The brush roller, mop roller, and omni-wheel assembly are all easy to remove and clean. Hair buildup is manageable, and the self-cleaning process worked fairly well during our testing.

As with most roller-style mop systems, there is slightly more maintenance involved compared to spinning mop pads, but the tradeoff is usually stronger overall floor coverage and more consistent scrubbing performance.

The roller itself can also be removed and machine washed if necessary, which is a nice convenience feature for long-term maintenance.

Final Thoughts

The Eufy C28 ends up being a very capable mid-range robot vacuum and mop that focuses heavily on roller-mop performance, pet-hair handling, and overall convenience. Its Duo Spiral anti-tangle brush system works extremely well in homes with pets or long hair, while the oversized roller mop delivers impressive hard-floor cleaning performance.

There are still areas where the robot could improve. Battery coverage falls short of expectations, fine-particle carpet pickup could be stronger, and premium features like hot water mop washing, mop extension, and side-brush extension are notably absent.

Even so, the C28 performs very well in the areas that matter most for many households, especially homes with pets and hard flooring. At the right discounted price, it offers a strong combination of cleaning performance, convenience, and value that makes it an easy model to recommend for mid-range buyers.
