Both robots use roller mops and LiDAR mapping, so the decision comes down to what happens after the cleaning run. The DEEBOT T80 Omni washes its roller with 167°F water, runs for nearly five hours on a charge, and extends its mop arm to reach baseboards, making it the pick for large hard-floor homes. The eufy Omni E28 counters with dual main brushes, two side brushes, 20,000 Pa suction, and mapping for up to five floors, which suits carpet-heavy or multi-story houses better.
Roller mops are still the newest approach to robot mopping, and here are two machines that both use one. That shared starting point makes the rest of the comparison unusually clear. The Ecovacs DEEBOT T80 Omni leans into mop maintenance and endurance: hot-water washing, an extendable mop arm, and a runtime that stretches close to five hours. The eufy Omni E28 puts its effort into pickup, with a dual brushroll, two side brushes, and stronger suction, plus mapping that stretches across five floors. And there's a real price gap between them, which changes the math for a lot of buyers.
Ecovacs DEEBOT T80 Omni
out of 10eufy Omni E28
With an 8.2 overall rating for the Ecovacs DEEBOT T80 Omni and an 8.0 for the eufy Omni E28, these two rate close enough that your priorities decide it. The Ecovacs pulls ahead on cleaning, 8.6 to 8.0, so it handles ground-in dirt and messy floors better. The eufy answers with a stronger 8.9 navigation rating against 8.1, meaning smarter room mapping and fewer stuck-under-the-couch moments. Features land nearly even at 6.6 and 6.5. Both deliver solid value, with the Ecovacs punching above its price.
Start with the brushes. The E28 runs a dual rubber-and-bristle roller plus two side brushes, one of which extends into corners, against the T80 Omni's single roller and single side brush. Suction favors the E28 too, 20,000 Pa to 18,000 Pa, with a bigger onboard dustbin. Flip to mop care and the picture reverses: the T80 Omni washes its roller at 167°F and holds a larger clean water tank and larger dirty water tank in the dock, so it goes longer between refills. Endurance is a real gap as well, 297 minutes versus 216 minutes. And mapping reach differs sharply, five levels on the E28 against two on the T80 Omni.
The E28's dual rubber-and-bristle brushroll, two side brushes (one extendable), 20,000 Pa suction, and larger onboard dustbin add up to a stronger pickup setup than the T80 Omni's single brush, single side brush, and 18,000 Pa. The T80 Omni answers with a liftable main brush that keeps hair and debris off the roller when it switches to mopping.
Both use roller mops, but the T80 Omni maintains its roller better: 167°F wash water, 200 RPM against 180 RPM, adjustable moisture rather than three fixed levels, and an extendable mop arm for edges. The E28 presses harder at 14.7 N versus 6 N and dries slightly hotter at 122°F.
For shedding dogs and cats, the E28's 20,000 Pa and dual brushroll pull ahead of the T80 Omni's 18,000 Pa single brush. The bigger onboard dustbin also means fewer trips back to the dock during heavy hair season.
Both use LiDAR plus a camera, but the E28 stores maps for up to five floors compared to two on the T80 Omni, which matters in a townhouse or a home with a finished basement. The T80 Omni's obstacle system pairs AI, camera, and 3D structured light, and the two clear obstacles at 20 mm and 21 mm respectively.
The T80 Omni's dock washes the mop with 167°F water, self-cleans, and carries larger clean and dirty water tanks, so refills and dumps come around less often. The E28 adds detergent automatically during mop washing, which gets the roller cleaner than water alone, and dries at 122°F.
The T80 Omni runs 297 minutes on a 6,400 mAh pack against 216 minutes on the E28's 5,200 mAh, a solid advantage for big open floor plans. The E28 covers 1,600 square feet in a single run, which is plenty for most homes.
Both handle voice control, no-go zones, multi-level maps, smart carpet cleaning, and smart obstacle avoidance. The T80 Omni adds built-in voice commands alongside Amazon and Google, and the E28 covers Amazon, Google, and Apple.
