eufy C28 Review: We Compared the 2026 Robot Vacuum on Hard Floors

If you bought a Eufy RoboVac a few years ago, you know the routine. A basic bot bumps its way around, picks up surface dust, and needs its tiny bin dumped after every run. The C28 is a different machine. It packs a roller mop that scrubs instead of dragging a damp cloth, a self-emptying dock that also washes and dries the mop, LiDAR room mapping, and a brush designed to shed pet hair instead of wrapping it. The jump from a 2019 entry-level bot to this 2026 model is large enough that "upgrade" does not quite capture it.

Owner feedback and published specs indicate that the eufy C28 is the most complete robot vacuum and mop eufy has made. The roller mop cleans hard floors better than any flat vibrating pad tested, the brush genuinely resists hair wrap, and the dock handles maintenance for weeks at a time. Battery life keeps it from being a true whole-home, single-session cleaner on larger layouts. 8.5/10.

Best for: Pet households with mostly hard floors who want daily automated cleaning and are fine splitting larger homes into zones.

Skip if: You need one uninterrupted run to cover 2,000+ square feet, or edge-to-edge mopping right up to the baseboard matters to you.

At a Glance

What We Liked

The Roller Mop Actually Scrubs

Most robot mops in this price range drag a flat vibrating pad across the floor. That pad pushes dirty water around once the first room is done. The C28 uses a spinning roller mop with a clean-water feed and dirty-water collection, the same idea behind full-size floor scrubbers. Owner reports confirm the dirty-water tank regularly contains visible brown residue after cleaning, indicating the mop pulls grime out of the floor rather than just smearing it. Multiple owners say the roller leaves tile and hardwood cleaner than a manual Swiffer pass.

Hair Does Not Stand a Chance

The DuoSpiral brush uses two counter-rotating rollers with a gap down the middle. Hair slides toward that gap and gets sucked into the bin instead of wrapping around the brush ends. Owners with multiple long-haired pets report not needing to clean hair off the brush even after months of daily use. This design detail is significant for anyone who has spent time cutting tangled hair off a vacuum brush.

Quiet Enough to Run While You Work

At approximately 55 dB on hard floors, the C28 is quieter than most upright vacuums and many cordless sticks on their standard power setting. Several owners coming from older Roombas and earlier eufy models specifically note how much quieter the C28 is, making daily scheduled runs practical without disturbing conversations or work calls.

The Dock Does the Dirty Work

The C28 dock auto-empties the dust bin into a 3L bag and washes the roller mop mid-cycle so dirty water is not dragged across the floor in later rooms. When the robot finishes, the dock runs a wash cycle and then dries the mop with warm air. One owner noted the bag had not filled after a month of daily use. Between the 75-day bag capacity and the self-cleaning mop, maintenance frequency drops significantly compared to basic robot vacuums.

Where It Falls Short

Battery Life Caps Single-Session Coverage

The C28 cannot finish a large single-story home on one charge. Owners with open floor plans over roughly 1,800 square feet report the robot returning to the dock mid-clean for a recharge before resuming. The workaround is splitting the home into zones and scheduling them on different days, but this means no whole-house clean in one go. For apartments and smaller homes, this is not an issue.

Consumables Add Ongoing Cost

Replacement dust bags and the branded cleaning solution are recurring expenses that a basic robot vacuum does not have. The bags are proprietary, so generic alternatives are not available. Over time, these consumables add to the total cost of ownership.

The Dock Is Loud When It Empties

The C28 itself is quiet, but the dock is loud during bin emptying and mop-wash cycles. Both cycles are short but noticeable, similar to a regular vacuum running at full power for 10 to 15 seconds. Scheduling emptying for times when you are out of the room is advisable.

That Inch Along the Baseboards

The roller mop does not extend all the way to the edge of the robot, leaving about a one-inch unmopped strip along baseboards and kitchen toe kicks. This is common across roller-mop robots because the mop mechanism sits behind the chassis edge. If edge-to-edge wet cleaning is a priority, a robot with an extending or swinging mop arm will do a more thorough job at the perimeter.

Real-World Performance

Hardwood and Tile: Daily Kitchen Mess

Owner reports describe the C28 effectively picking up visible dry debris such as crumbs, coffee grounds, and light dust on ceramic tile and sealed hardwood floors. The mop pass removes dried spots and general haze, leaving floors visibly cleaner. Skipping a day of mopping may result in faint streak marks where grime has built up.

Low-Pile Rugs: Pet Hair Week

The C28's vacuum pass collects pet hair and fine dust from low-pile rugs without filling the bin on rug passes alone. The mop auto-lifts 10.8mm when rolling onto rugs, keeping fabric dry. On thicker medium-pile rugs, the lift clearance is adequate and no damp streaks are reported.

Zone Scheduling: Set It and Mostly Forget It

The LiDAR map setup and no-go zone drawing are straightforward in the eufy Clean app. Owners report that after initial setup, the robot runs unattended with minimal intervention, such as refilling the clean-water tank and emptying the dirty-water tank occasionally. This scheduling approach suits households wanting automated daily floor cleaning.

How It Compares to Alternatives

Compared to basic eufy RoboVac models like the E25 or 11S, which are vacuum-only and navigate by bump sensor without a dock, the C28 adds LiDAR mapping, roller mopping, self-emptying, and mop washing. It represents a different product category under the same brand name. For those prioritizing mopping and hands-off maintenance, the C28 justifies the upgrade.

In the wider robot vacuum market, the C28 competes with mid-range self-emptying bots that mop. Some models at a similar price offer extending mop arms for baseboard coverage, while others use dual spinning pads. The C28's roller mop scrubs more effectively on dried-on mess but leaves an inch unmopped along edges. Our best robot vacuums roundup details trade-offs across brands and budgets.

For mostly carpeted homes or vacuum-only needs, a dedicated cordless stick vacuum or upright vacuum will pick up embedded hair more deeply than any robot. The C28 excels on hard floors with rugs, where the mop performs real cleaning and the vacuum handles surface debris.

Who Should Buy It

Ideal buyer: You live in a home or apartment mostly with hard floors and some low-pile rugs, have a shedding dog or cat, and want to automate daily floor cleaning without flagship pricing. You are comfortable splitting the home into zones if over 1,500 square feet and don't mind occasional baseboard wiping.

Skip it if: You need one run to cover a large open floor plan end to end, want edge-to-edge mopping with no strip left behind, or have mostly carpet where mopping hardware is unnecessary.

What you get: For the price of a mid-range robot vacuum, the C28 bundles a roller mop, self-emptying and mop-washing dock, LiDAR navigation, and a brush that genuinely does not tangle. These features were reserved for much more expensive robots just two years ago. The trade-offs (battery range, baseboard gap, dock noise) are real but do not negate the core value: a robot that vacuums and mops hard floors well enough to skip both chores most days.

FAQ

Does the roller mop clean close to the baseboards?

No. It leaves about a one-inch unmopped strip along walls and baseboards. The roller mop sits behind the chassis and does not extend outward. Periodic hand wiping of baseboards is necessary.

Is it loud compared to other robot vacuums?

At roughly 55 dB, the C28 is quieter than most robot vacuums and many cordless stick vacuums on standard power. Owners coming from older Roombas say the C28 is the quietest robot they have owned. The dock emptying and mop-wash cycles are loud but brief.

Does it get tangled with pet hair?

The DuoSpiral brush design prevents hair from wrapping around the roller. Owners with multiple long-haired pets report no need to clean hair off the brush after months of daily use.

Will it mop my rugs?

No. The C28 senses carpet and automatically lifts the mop 10.8mm, switching to vacuum-only mode. On low-pile and medium-pile rugs, the lift clearance keeps fabric dry.

How long does the self-empty bag last?

The 3L dust bag holds up to 75 days of debris for most households. One owner reported the bag had not filled after a month of daily use in a pet household.

Can it clean my whole home in one session?

It depends on home size. For apartments and homes under roughly 1,500 square feet, the C28 can finish in one session. Larger single-story layouts likely require mid-clean recharge or zone splitting. This is the most common complaint from owners with open floor plans.

Bottom Line

The eufy C28 does what a robot vacuum and mop should do in 2026: it scrubs hard floors instead of smearing them, handles pet hair without tangling, and its dock automates maintenance most robot owners dislike. Battery life limits larger homes, and the baseboard gap means it is not a fully set-it-and-forget-it system. For pet households with mostly hard floors and layouts under 1,500 square feet, or those willing to zone larger spaces, it is the most practical robot eufy has shipped.
