Eufy E28 Omni Robot Vacuum Review: 3-in-1 Cleaning with Built-In Spot Cleaner

Eufy, one of the longest-running robot-vacuum brands, has been experimenting with fresh ideas. The Eufy E28 follows that trend by combining three floor-care tools in a single device: a robot vacuum, a hard-floor mop, and a handheld spot-cleaning machine. Here’s how the E28 performed in our independent tests.

Eufy E28 Pros

Eufy E28 Spot Cleaner 

The E28’s most novel addition is its detachable spot cleaner. A cover panel lifts off the dock, revealing a hose with trigger, brush, and spray nozzle—essentially a compact upholstery cleaner that’s always charged, filled, and ready to work.

The spot cleaner is exceptionally convenient because it sits pre-filled on the dock, eliminating the need to haul a separate machine out of storage. A dedicated self-cleaning button flushes the hose after each use, so upkeep is minimal.

Suction power on the spot cleaner surpasses that of the popular Bissell Little Green, and although it falls slightly below the overall category average, the E28 still removed pre-treated coffee and grape juice stains, plus a wet spill with ease.

For households with pets or frequent spills, having a ready-to-go spot cleaner in the room is a genuine convenience, although long-term hose durability may be a consideration for heavy users.

Eufy E28 Performance

In testing, the Eufy E28 proved to be an effective robot vacuum across all of our sweeping tests. It handled surface debris on both hard floors and carpet, picking up everything from fine dust to oversized crumbs without spreading debris around or leaving traces behind.

Its automatically extending side brush took care of edge cleaning, sweeping dirt from along the edges of walls and furniture into the suction path of the robot.

Most impressive, the E28 removed 85 percent of deeply embedded dirt in the carpet-deep-clean trial—a top-eight score among more than 150 robots evaluated and a full ten points above the 75-percent category average. 

Test	Result	Category Average
Surface debris (hard floors & carpet)	Excellent – no issues with fine to XL debris	—
Edge pick-up	Good edge coverage, thanks to an automatically extending side brush	—
Carpet deep clean (embedded debris)	85 % (Top-8 score out of 150-plus robots)	75 %

Eufy E28 Obstacle Avoidance

With a front-facing camera and multiple sensors, the E28 successfully avoided 23 objects out of 24 in our obstacle tests—which is among the best results to date. It reliably avoided cords, shoes, pet waste, and other common floor hazards.

Eufy E28 Mopping

The single roller mop offers one decisive advantage over dual spinning pads: it can handle wet liquids, squeegeeing them into the onboard dirty-water tank.

In testing, it posted an impressive stain-removal score of 127, well above average.

Although it left behind 1.3 grams of water—slightly more than average and therefore prone to occasional streaks—it protects carpets by automatically lifting the roller when carpet is detected, or users can simply instruct the robot to avoid carpeted areas altogether. Taken together, these results give the E28 an above-average overall mop rating.

Performance Metric	Eufy E28 Result	Context / Why It Matters
Stain-removal score	127 (well above average)	Higher scores mean better removal of dried-on stains.
Water left behind	1.3 g (slightly above average)	Extra water can cause occasional streaks on glossy floors.
Wet-spill handling	Yes – roller channels liquid into dirty tank	Spinning pad robots don’t store dirty water, less good at wet spills
Carpet protection	Roller auto-lifts 10.5 mm or avoids carpets	Keeps rugs and carpet edges from getting damp while mopping.
Overall mop rating	Above average	Strong cleaning power plus safety features for mixed surfaces.

Eufy E28 Multifunction Dock

The E28’s multifunction dock handles nearly every post-cleaning chore on its own. Once the robot parks, the dock will:

• empty debris in a disposable bag,
• scrub the mop roller with fresh water,
• drain the dirty-water tank,
• replenish the clean-water reservoir with detergent,
• and finishes by drying the roller with hot air.

Apart from lacking hot-water washing, this routine delivers a full suite of premium, hands-off maintenance features that keep the robot and the spot cleaner ready for its next use.

Dock Function	What It Does (Why It Matters)
Dustbin auto-empty	Transfers debris into a sealed bag, eliminating messy bin dumps
Cold-water roller wash	Removes grime from the mop roller to prevent cross-contamination
Dirty-water tank drain	Empties collected wastewater so the dock stays odor-free
Clean-water tank refill (with detergent mix)	Ensures the robot starts each job with fresh cleaning solution
Hot-air roller drying	Dries the roller to discourage mildew and unpleasant odors

Eufy E28 Navigation

The Eufy E28 uses a top-mounted LiDAR scanner, which we have found to be more accurate than the internal, body-mounted versions many rivals use.

The Eufy’s LiDAR moved it through our floor plan with efficient, orderly coverage, and it performed better than the average in our tests.

Metric	Eufy E28 Omni	Category Average
Navigation efficiency	0.9 m²/min	0.7 m²/min

Eufy E28 App Experience

Paired with Eufy’s highly rated mobile app, the system provides multi-level mapping, lets users draw virtual no-go zones or target specific rooms for cleaning, offers adjustable obstacle-avoidance sensitivity, and even allows granular control over how often the dock empties the dustbin or washes the mop roller.

Average Results

Battery Efficiency

Battery efficiency proved a mixed bag. On paper, the E28’s power management is slightly below the category norm, but its generous battery capacity and systematic LiDAR navigation offset that deficit.

In practical terms, the robot covers roughly 1,200 square feet on a single charge—just edging above average floor coverage figures. Users in mid-size homes can expect the E28 to finish a full cleaning cycle without pausing to recharge, though sprawling layouts may still require a top-up.

Metric	Eufy E28 Omni	Category Average
Battery efficiency (minutes per % charge)	1.24 min/%	1.31 min/%
Average floor coverage per charge	1,207 sq ft	1,015 sq ft

Pet hair pickup

In our standardized 2.5-gram pet-hair test, the Eufy E28 delivered an unremarkable but serviceable performance, matching the category average of 81%. It successfully removed most loose fur from both hard floors and low-pile carpet but did not outperform competing models that specialize in pet hair.

For households with moderate shedding, the E28 should suffice, yet those grappling with heavy-shedding pets might consider a unit with stronger agitation or tangle-resistant brushes.

Eufy E28 Cons

Hair Tangles

A redesigned two-part main brush channels hair toward the center to prevent tangles with typical pet fur, but in seven-inch-hair testing the E28 struggled. Long strands accumulated behind the brush and rolled into dense “hair cigars,” earning the worst score ever recorded in that category and signaling a potential problem for households with very long hair.

Bench Tests

Suction and airflow are merely average for a robot in this price bracket. While the E28 cleans well in most scenarios, raw power lags behind the class leaders, so buyers expecting premium-tier suction may be underwhelmed.

Metric	Eufy E28 Omni	Category Average
Airflow (Max Power)	14 cfm	16 cfm
Suction (Max Power)	0.57 kPa	0.83 kPa

Small Dustbin

The onboard dustbin holds just 300 milliliters of debris. The dock’s automatic emptying alleviates the small capacity, yet the robot must return more often to empty, shortening continuous run time—which could be an inconvenience in larger homes.

Replacement Needs

One lingering concern involves durability: a user who relies on the spot cleaner every day to tackle messy spills may find the hose and fittings wearing out sooner than expected. Because the spot-cleaner module is integral to the robot, its lifespan could ultimately limit the vacuum’s longevity unless spares are accessible. Eufy does offer replacement brushes, which is encouraging, but other consumables may also be needed. Time will tell.

Verdict

The Eufy E28 currently stands at 15th place on the Vacuum Wars Top 20 Robot Vacuum list with an overall star rating of 3.86 (average: 2.8 stars). 

It delivers excellent vacuuming, outstanding obstacle avoidance, and a feature-rich dock—plus the unique benefit of an always-ready spot cleaner. 

Potential buyers should weigh the risk of long-hair clumping and some possibility of extra wear and tear on the hose, but for many homes—especially those with pets—the E28’s versatility makes it a compelling choice.
