Robot vacuum manufacturers are constantly trying to outdo one another. One company develops a detachable cordless vacuum for the robot’s dock, and the next makes the robot’s dustbin a detachable cordless vacuum. Now, Eufy is upping the ante with the first robot vacuum to also have a detachable spot cleaner for carpet and upholstery.

The Eufy Omni E28

Aside from detachable cordless vacuums, a mop roller system is another big thing for robot vacuums; many makers, including SwitchBot

The Omni E28 also has a mop roller, which looks similar to the S1 Pro but not identical. The Eufy Omni S1 Pro

However, continuously spraying the roller with clean water inside the robot keeps it moist. Scraping off the dirt and wringing out the dirty water as the roller spins ensures your floors are clean instead of streaky or filmy. The Eufy Omni E28, like the S1 Pro, is the closest thing to a manual mopping result you can get from a robot vacuum and mop. 

Also: I love a vacuum and mop to clean dry and wet messes, especially when it’s on sale

The E28 and E25 robot vacuums have 20,000Pa of suction power and anti-tangle technology, including a DuoSpiral double roller brush to remove pet hair and avoid entanglements. The robots are self-emptying robot vacuums with a self-washing mop roller. The only difference is the portable spot cleaner, which only the E28 has.

There’s no separate detergent tank for the spot cleaner, though you could add some detergent directly into the clean water tank. I recommend using just water in the clean water tank and spraying your preferred carpet or upholstery cleaning solution directly on the stains to pre-treat them. You can then scrub the mess clean with the Eufy E28 brush and rinse out the detergent. 

ZDNET’s buying advice

The Eufy Omni E28 instead, which I use to clean our carpets at least once every quarter.
