The Eufy E28 Omni robot vacuum and mop just hit its lowest price ever at $850, a total of $450 off with an on-page Amazon coupon.

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 is a robot vacuum and mop with a portable spot cleaner for carpets and upholstery. You can run your robot vacuum as you would any other, but you can also pick up the top with a built-in retractable handle and do some deep cleaning on carpets, rugs, or upholstery. I’ve been testing this robot vacuum over the past couple of weeks, and I’m happy to report on its performance. 

Essentially, the deep cleaner you carry is the Omni station’s clean and dirty water tank, so it’s where the robot autonomously sources clean water for its mop when it’s at the dock. The deep cleaner has a handle for spot-cleaning with a hose, so you can set it down near where you want to clean and plug it in without holding it as you clean. 

Aside from detachable cordless vacuums, a mop roller system is another big thing for robot vacuums; many makers, including SwitchBot, Yeedi, and Ecovacs, are moving away from detachable rotating mop pads and using mop rollers instead. Eufy’s also done this before with the flagship S1 Pro. 

The Omni E28 also has a mop roller, which looks similar to the S1 Pro but not identical. The Eufy Omni S1 Pro is unequivocally the best mopping robot vacuum I’ve ever tested, so I was excited to test the new Omni E28, which features a very similar system. Thankfully, the Omni E28 didn’t disappoint. 

The large mop roller covers the length of the vacuum’s width and leaves no streaks behind during mopping. Streaky floors are one of my biggest pet peeves when testing robot vacuum and mop combinations, and they’re a more common occurrence than I’d like.

Eufy is also launching an E25 robot vacuum, which features the same HydroJet self-cleaning mop system as the E28. The robot’s mop roller is continuously scraped clean as it spins, and it keeps clean and dirty water in separate tanks within its body, so it only mops with clean water. The mop also exerts more downward pressure to ensure deep cleaning than the S1 Pro, with 1.5kg (3.3 lbs) instead of 1kg. 

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.

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.

The spot cleaner proved to be very effective. It’s heavy, like most spot cleaners when full of water, but it has a retractable handle on top that makes it easy to carry around. You also don’t have to press any buttons or move anything to release it; just unplug it, pull the retractable handle, and go. 

I didn’t like that the spot cleaner powers the base station, so if you take it somewhere else in your home to clean, the robot’s charging station is left without power until you return it. This is fine for quick cleanups, but it can be annoying when a forgetful house member takes the spot cleaner upstairs and leaves it in a room for two days after they’re done (totally not me).

The spot cleaner has a self-cleaning hose attached, but no other attachments. The hose ends in a static brush head that sprays clean water, which you use to clean messes on soft surfaces, like carpets, rugs, and upholstery. Since it isn’t motorized, you must manually brush the rug or fabric with the brush head to scrub it clean. Once you’re done, you just have to press a button along one end of the brush head to make the spot cleaner cycle clean water through the hose without spilling, cleaning the hose for you. 

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 is designed to solve a big problem for many US customers: the need for regular floor cleanings and the ability to quickly clean up messes on soft surfaces in a single device. This device isn’t meant to replace your existing carpet cleaner, but it’s perfect for consumers who may need a spot cleaner and are also in the market for one of the best robot vacuum and mops available.

Also: Spring cleaning takes me no time with my favorite smart home devices

I’m not a fan of fully carpeted living spaces, but my home has carpeted bedrooms, one of which we use as our TV room. With three young kids who have movie nights and play time in that TV room, its carpet unfortunately sees a lot of spills. I was in the market for a spot cleaner for a while, but decided to buy a full carpet cleaner instead, which I use to clean our carpets at least once every quarter. 

But there are always little messes in between — whether it’s spilled ketchup on the carpet, a muddy shoeprint on the entryway rug, or yogurt on the fabric ottoman. So I appreciate having the Eufy Omni E28’s spot cleaner always handy. Instead of dragging out a heavy carpet cleaning machine and filling it with water to clean a 6-inch in diameter spill, I can just unplug and grab the E28, clean the mess, and return it to the dock with little work on my end. 

It’s also priced quite well for a first-of-its-kind device with a flagship-level robot vacuum and mop. The Eufy Omni E28 robot vacuum, mop, and spot cleaning combination is now available on Eufy’s website and Amazon for $1,000. The Eufy E25 robot vacuum and mop without the spot cleaner will be available in June for $900.
