I trialled the eufy Omni C28 robot mop and vacuum on every type of floor in my house

I've seen a rise in the trend of robot vacuums, and I wanted to test the next generation and give a robot mop and vacuum a go to see if they're worth the hype.

I got the newly released eufy Omni C28 to test the latest model of robot mops and I tested it out to see how it performed on every type of flooring in my house.

I reveal the results below and give my opinion on whether it's worth the cost and clarify some misconceptions that I and maybe you have had about them.

How the robot mop was tested

I decided to try the eufy Omni C28 on every type of flooring in my house to see how it performs on each one.

This focused on wooden flooring in my lounge, limestone tiles in my kitchen, the carpet in the living room and the terracotta tiles in the drawing room.

With each of these, I wanted to test the Omni C28 on its most powerful function on the 'Deep' cleaning function, the 'High' water level and the 'Max' suction power. I also used the same washing-up liquid.

I also tried some other tests to really put it through its paces, and I can reveal the results for each flooring type.

Alongside the cleaning performance, I was also interested in how the robot handled navigation and maintenance. The C28 uses iPath 2.0 navigation, which maps the room layout and helps it avoid obstacles, even in darker areas or under furniture.

The before and after of a eufy Omni C28 robot clean on a wooden floor

The lounge uses basic wooden flooring, which was a good starting ground to test the eufy Omni C28.

With the mapping feature, it was able to assess the room size, surface type and where it could, and couldn't clean.

With the vacuum at the front and the mop behind it, the robot first pulled up dust and debris before mopping. The roller mop system – which applies around 1kg of downward pressure while cleaning – continuously washes itself as it goes, meaning it’s not just pushing dirty water around the floor.

This was a surprise as, despite its size, it performed well compared to my larger Dyson vacuum to give a very good finish. Dare I say, I couldn't have done it better myself.

The kitchen proved tougher to clean for the Omni C28

I wanted to give a significantly tougher test, so I took it to the kitchen next. This Italian tumbled limestone flooring proved much tougher to clean for the eufy Omni C28.

Due to the bumpy surface, some stains were tougher to clean than others and this room definitely needed a couple of goes to achieve a full clean. However, I did deliberately leave some trickier stains.

I tried the eufy Omni robot mop/vac on different stains

On the first run the vinegar was spread slightly and the beetroot stain only partially lifted. However, the self-cleaning roller mop kept washing itself during the process, which meant the second cleaning pass was far more effective. After another run, both stains were removed.

This is where the automation really helped. Since the robot can return to its docking station to wash the mop, refill water and empty dust automatically, it’s designed to clean areas multiple times without you needing to intervene.

The largest room downstairs was the drawing room

sq ftIt should be pointed out that after cleaning both the lounge and kitchen, the eufy Omni C28 did need to clean itself and reload its water. This was after 300 sqft of cleaning.

The next room was the largest of the lot, with the drawing room and an adjacent connecting room giving the C28 a workout. These open-plan style rooms are really where robot vacuums/mops come in handy.

The result in this room was the best yet with the flat surface glimmering by the end, and even though I set the function to the highest water level, it was a real bonus that the floor was not too wet, meaning it dried almost instantly, a problem I often get when mopping.

If I was being really picky some water marks were left behind but that is me being very harsh.

Testing the robot on carpet

The living room carpet is thick and can be a challenge for vacuums

,Finally, I moved the robot onto the living room carpet, which is a thick, deep-pile carpet and therefore a good test.

This is where the 15,000 Pa suction power came into its own. The robot automatically recognised the change in flooring and lifted out of mopping mode so the mop wasn’t used on the carpet.

It also navigated easily underneath sofas, footstools and chairs – areas that often get missed in regular cleaning.

Another useful feature here is the DuoSpiral detangling brushes, which are designed to prevent hair and fur from wrapping around the rollers. For households with pets or long hair, this could save a fair bit of maintenance.

Despite working through several rooms, the robot was also very quiet. At times I barely noticed it running.

By the end, the entire ground floor of my house had been cleaned in around 45 minutes, and the robot only needed to recharge and service itself once.

FAQs

Does the eufy Omni C28 need much maintenance?

One of the main selling points of the Omni C28 is that most of the maintenance is handled automatically by the docking station. The all-in-one base station empties the dustbin, washes the mop roller, refills the clean water tank and collects dirty water.

However, you will still need to occasionally empty the wastewater tank, buy new dustbins, refill the clean water tank and clean the filters and brushes every so often to keep the robot running efficiently.

How loud is the eufy Omni C28 when cleaning?

The Omni C28 is relatively quiet compared with traditional upright vacuums. The maximum level it can reach is 67 dBs.

Does the robot work in low-light conditions?

The Omni C28 uses its iPath 2.0 navigation system, which allows it to detect obstacles and map rooms even in low light or under furniture. This means it can clean effectively at night or in darker rooms without needing the lights on.

Can you control the robot remotely?

Yes. The robot connects to the eufy Clean app, which allows you to start or stop cleaning cycles, adjust suction or water levels and set cleaning schedules remotely.

You can also use the app to see the robot’s room mapping and direct it to specific areas if you only want one room cleaned.

Will the eufy Omni C28 fall down the stairs?

I did also test the eufy Omni C28 upstairs and I did worry that it could fall down the stairs. However, it will scan if it is near an edge and stop itself everytime to prevent it falling an damaging itself.

Can the eufy Omni C28 go up slopes?

It can go up slopes as high as 45 degrees, however it cannot go up edges that are larger than an inch.

Is the eufy Omni C28 worth it?

If you’re looking for a robot vacuum that can both vacuum and mop with minimal maintenance, the eufy Omni C28 Robot Vacuum and Mop is one of the more compelling mid-range options currently available.

It also performs strongly for a robot in this price bracket. With 15,000Pa suction, it has enough power to lift dust, pet hair and debris from both hard floors and carpets. The HydroJet roller mop continuously cleans itself while scrubbing floors, helping prevent the streaking that some robot mops struggle with.

Originally launched at around £649, it is currently available for about £499 during Amazon’s Spring Deal promotions, making it considerably more affordable than many robot vacuums with similar automation features.
