You could spend a lot of money on a robot vacuum and mop combo without trying hard. However, the Eufy Omni C28 offers a mid-range alternative that does most of the same work as the premium models, but at a cheaper cost.

Price and availability

The Eufy Omni C28 is available for purchase now directly from the company and retailers like Amazon. It retails for $799.99, but is often on sale and has been as low as $499.99.

What does a mid-priced robot vacuum and mop get you?

You can think of robot vacuums and mops in three basic price tiers. Low-end models are somewhere around $350 and under, mid-range ones are somewhere between $400 and $800, and premium ones can range up to $2,000, or more.

For a mid-range unit, the Omni C28 is highly competitive as a robot vacuum and mop. It has a maximum of 15,000Pa of suction with a roller mop capable of 270RPM. There’s also 1kg (2.2 pounds) of downward pressure for the mop with continuous cleaning of the brush with fresh water.

The base station features mop washing with hot air drying, along with the standard dust bin collection, dirty water tank, and detergent dispensing. While the clean and dirty water tanks are a bit small at 2.2L each, I was still able to wash and clean for a full week before needing to handle the water tanks. If you reduce the amount of water the mop uses, you can stretch that a little longer than a few days.

Without any pets, I’ve been able to make the 3L dust bag last for up to two months at a time. This will really just depend on the amount of debris you’re picking up regularly.

My favorite feature of the Omni C28 is its docking station size. As someone who has tested a dozen of these products over the last 18 months, size matters. Some of the premium units are huge. This one is much more compact, and so it just isn’t as obtrusive as other ones from companies like Dreame or Roborock.

Navigating a home

The Omni C28 uses LiDAR for its mapping and object avoidance. This is the protrusion on the top, which gives it a good sense of the space it’s patrolling, in 3D. Anyone coming from a very old cleaning robot that bumped into things and then redirected will be astonished at how well the Omni C28 moves carefully around its rooms.

In my observations, I thought it did adequately when compared to the high-end, more advanced units. For example, there were times I could hear it wrestling with an end table with a low metal frame. It constantly tried to run over it and then couldn’t get out. I also came downstairs once to find a rogue USB-C cable that had been dragged from somewhere.

As disappointing as it is that the Omni C28 hasn’t been perfect in my testing, I’ve found that none are flawless. The vacuum was able to maneuver through chair legs, under couches, and around shoes just fine. If you have fragile or priceless items, you may want to set “no-go” zones, but otherwise, you should feel comfortable letting it move on its own.

Cleaning performance of a mid-range device

To get a sense of what the Omni C28 was capable of cleaning, I ran some manufactured tests. I put a few ounces of crushed Cheerios, coffee grounds, and flour on my hardwood floors. I set a cleaning zone around the messes and let the vacuum and mop run in the default configuration with a single pass.

The Omni C28 picked up most of the debris, around 95% of the total. It flung a few Cheerio pieces and left those scattered. It also left a bit of white flour dust that was easy to see because of its color. Even with close inspection, the unit appeared to capture all of the coffee grounds. This was a little better than expected for this type of test with this robot.

If you do have dedicated spills, the Omni C28 will be able to handle the bulk of the cleaning process. To get a more detailed performance, you’ll want to make sure it does two passes, where it will alternate patterns and should pick up even more of the debris.

While the dual front spinning brushes and the suction performed well overall, it’s the mopping portion that impressed me the most. One of the reasons to choose this robot instead of another one is the roller brush mop, instead of mopping pads.

There are pros and cons to each style, but in this case, Eufy is cleaning and applying water to the roller brush as it mops. This helps keep the floors even cleaner and spreads less mess around. I noticed fewer scrub marks, likely due to the constant water applied during mopping.

The fancier, more expensive units with this style mopping brush will move, slide it out to get closer to baseboards, and into other areas. This one doesn’t do that. It just means a little less wide coverage and more passes until a job is complete.

Should you buy the Eufy Omni C28?

If you’re coming from a low-end bump-and-clean robot, the Eufy Omni C28 will feel like a massive upgrade. Its navigation prowess is very good for its price range. Its cleaning skills are equally impressive for a cleaning device under $1,000.

The self-cleaning, self-emptying dock is a must-have with these wet-dry robots to make sure you’re not doing more work than you need to. The Omni C28’s dock is capable enough, and a good size, even if it is lacking in some minor ways.

The Eufy Omni C28 is a very good cleaning robot if you can get it on sale for under $600, or closer to $500. It’s a terrific value in that range. Just be aware that it’s not quite as polished as the more expensive ones, but it’s also not overbearing in all the ways the premium ones can be.
