My top-rated eufy robot vacuum just got an upgrade – on paper, it's better, but I'm sticking with the original

Over the past few years, robot vacuum cleaners have dominated the floorcare market. And as demand for hands-free cleaning continues to rise on a mammoth scale, brands like eufy have ramped up production to meet it. So, meet the Anker eufy Robot Vacuum E35 Omni, the brand’s latest addition to the squad.

The E35 Omni’s little sister has sat at the top of my best robot vacuum cleaner guide for the past year, with other makes and models failing to knock it off its pedestal. So I was eager to see whether the upgraded model, with its higher specs and added features, had what it took. This is what I found out.

In a nutshell

Last year, I tested the eufy Robot Vacuum Omni E25, and its power and precision quickly made it my new number-one rated robot vacuum. The new E35 supposedly builds on what worked for the E25 and improves it… and in some ways it does. In others, it doesn’t.

The design is sleek, and the docking station is relatively compact compared to other models on the market. Plus, I genuinely can’t fault its cleaning ability. With 35,000Pa of suction power, it tackled dry debris with an ease you rarely see without getting hands-on, and the HydroJet mopping system leaves hard floors sparkling while removing 99.99% of bacteria. In fact, I’d go as far as to say that it offers some of the best robot vac-mop cleaning I’ve ever come across.

The app is uncomplicated and easy to use, while still offering the customisability you’d expect from a big brand like this. It also offers enough cleaning modes and features to make the docking station and bot as hands-off as possible. Still, I found this new model couldn’t really figure out what it was, where it was, or where it was going.

During testing, I ran into quite a few problems with the E35’s mapping and navigation technology that I didn’t expect from such a high-tech model. Don’t get me wrong, it was still usable and didn’t turn me off completely, but it did impact the areas cleaned and my overall enjoyment of the robot vac. After all, when I'm paying £1,000, I want it to scrub every inch of my floors seamlessly.

Unboxing, setting up and first impressions

Testing robot vacuums is like my own personal gym workout - especially as a 5’2” woman with very weak arms. This became clear when the Anker eufy Robot Vacuum E35 Omni arrived at my door in a hefty box weighing a whopping 20kg.

Normally I try to struggle and carry these boxes into my house by myself, but this time I knew I genuinely needed a helping hand. So keep that in mind if you live alone or have mobility issues.

Nevertheless, unboxing and setting up the E35 Omni was relatively pain-free after my husband carried it into the dining room. There were very few parts to click together, a dust bag was already pre-installed, and it was pretty much plug-and-play. The only things I needed to do were fill the clean water tank with fresh water and then fill the detergent cartridge with the detergent from the bottle.

And, strangely, despite being very heavy, this model is actually very compact and smaller than other robot vacuums I’ve tested. This was a huge tick, as I like my on-show appliances to be as small as possible.

My only other niggle at this stage was that the dock and some smaller parts were packaged in PE-C7 plastic, which isn’t generally recyclable. I expected a big brand like eufy to have moved away from such eco-unfriendliness by now, so this was a shame.

Nevertheless, with everything assembled, I could link the E35 Omni to the Anker eufy app and let the robot vacuum map out the downstairs of my house. This took less than 10 minutes, but I have to admit that it wasn’t 100% accurate.

While the robot vacuum managed to pick up the main rooms downstairs, it completely ignored my hallway and downstairs toilet - despite the fact that they’re connected to the rooms it did map, and I left the doors open for the robot to discover them.

In the end, I moved the E35 Omni into my hallway and found it could map the entire downstairs without any issues. This was pretty frustrating, as I don’t like appliances cluttering up my hallway, but for some reason the mapping function had an issue with its initial placement.

Ease of use

One thing I always love about Eufy products is the easy-to-use app. I’m already familiar with the app, as I have three of their security cameras for my house, and the robot links directly to the same app, so I can control everything from one place.

But if you’re new to this app, I’m happy to report that it offers the best of both worlds. It’s a no-frills app that’s not complicated in any way, shape, or form, but it still offers the customisation robot vacuum owners need to make the most of it.

The app's most important feature is the ‘Mode’ setting, where you can choose how you want your E35 Omni to clean. Here you can choose between vacuum + mop or vacuum-only, adjust the cleaning intensity (‘Fast Cleaning’ covers the main areas of a floor but omits corners and edges, while ‘Deep Cleaning’ takes longer but covers all corners and gaps), and even the water flow and suction levels.

It’s customisable without being convoluted, and you can also toggle between whole-map cleaning or ask the robot vacuum to focus on a single room or area. Plus, you can set up schedules, adjust base settings, manage the map, or even turn on the child lock if you have young ones in the house.

One feature I also always like in an app is the ability to check the lifespan of the accessories, and the eufy app gives detailed information on the percentage and the hours left before features like the side brushes, sensors, and rolling brush need cleaning or replacement. You can also buy replacements via the app.

All in all, there’s not much more you could need from a robot vacuum cleaner app. If it offered anything more, I think it would just be overkill.

Performance

With 35,000Pa of suction power, the Anker eufy Robot Vacuum E35 Omni is one of the most powerful models I’ve ever tested - and a huge step up from the 20,000Pa of the E25 Omni. This new model also uses AeroTurbo 2.0 Multi-Cyclone Filtration, which means it spins the dust before it clogs and, in theory, should offer 365 days of consistent suction - without any loss of power. So, I was excited to put it through our robot vacuum cleaner testing process.

First, I threw sugar, crushed cereal, and my dog’s hair onto hard flooring. As you can see in the video, it picked up 99% of the debris in one pass. The only thing left behind was a little hairball, which the robot picked up when it came around again.

I then repeated this on my carpet and got equally impressive results, proving the suction power is as good as advertised. Again, the bot picked up little hairballs of mine and my dog’s on the carpet and my rugs, but it eventually sucked them up as it made its way around the space. And as someone who lives in a hairy household, I’ve yet to test a robot vacuum that doesn’t do this.

For the second test, I spooned some yoghurt onto my floors and let that dry before spooning on some more wet, fresh stuff to test its mopping power - and this is where it really thrived. Not only did the E35 Omni clean up the yoghurt with its HydroJet mop technology, but it also detected the dry yoghurt stains and kept cleaning the affected area until it was confident it had removed them 100%. And it did so extremely well. No lingering residue or even a smell remained.

Next up was the obstacle test, which had very varied results. When I put obstacles in its way, the E35 Omni really struggled to figure out its route around them. It immediately barged into one and pushed it out of the way, but then it detected the second one without any problem. This inconsistency carried on through real-life testing, too.

When the robot followed the map, it avoided obstacles quite well. It navigated my dining room chairs with ease, diverted around my dog’s food bowl with minimal fuss, and avoided bumping into large pieces of furniture. So, I can only conclude that the E35 Omni handles expected obstacles well, but doesn’t cope as well with unexpected ones.

I also appreciated the extendable arm, which cleaned right up to (some) of my kitchen cabinets and the skirting boards in my living room. However, one major flaw I found during testing was that the general navigation system often left the robot wondering where it was, or where it was supposed to go.

Sometimes it completely cut large areas of the room from its cleaning schedule, and other times it ditched the traditional zig-zag pattern for a random one that didn’t make sense, especially when it faced large, open, empty stretches of floor.

You can see this in the app screenshots earlier on, where it started cleaning my hallway and some of my living room in the zig-zag pattern before ditching that for a random one in the living room and the kitchen - not cleaning the edges at all, despite being in ‘Deep Clean’ mode. During this cleaning session, it also finished cleaning and headed back to the dock despite missing a huge portion of my dining room.

Also, the bot returned to the dock three times during one 45-minute cleaning session. It did this to clean and wash the mop, which I understand from a hygiene perspective. But this really interrupted the cleaning cycle, and I imagine it’ll need to do this even more if you have a larger home.

Cleaning and maintenance

While the E35 Omni had some disappointing performance issues, it definitely made up some ground with its cleaning and maintenance. Or, should I say, the lack of it.

As with any robot vacuum cleaner, you need to empty the wet debris chamber, but the beauty of high-tech models like this one is that the dock does everything else for you.

After every cleaning session, the robot vacuum gives itself a good deep clean - immediately emptying the dry debris into the 3L dust bags (which, depending on your usage, could hold up to 75 days’ worth of dirt, dust and hair), washing the mop with 60°C hot water and then drying it with 55°C hot air to keep it clean and prevent mould growth or nasty smells.

I must admit the drying process takes quite a while (for example, one cleaning session ended at 8 pm, and it didn’t finish drying the mop until 2:30 am), but I do appreciate the care and attention the mop roller gets.

The charging time is much speedier, though, and I found that the robot vacuum could go from around 40% to 100% in just two hours - which meant that if I did want to give my floors another clean before the mop was bone dry, it at least had the charge, even if it was still damp.

As mentioned, the app lets you track any extra cleaning or replacement parts you need, so it requires very little hands-on input. But if you want to get up-close-and-personal, you can easily click the integrated dust bin and rollers in and out to remove any lingering dust or wrapped hair (if any).

How does it compare to similar models?

I would be doing eufy - and myself - a disservice by not comparing the Anker eufy Robot Vacuum E35 Omni to its older model, the eufy Robot Vacuum Omni E25. Especially as it’s been my top-rated model since August 2025.

On paper, the E35 is significantly better than the E25. It has 35,000 Pa of suction compared to the E25’s 20,000 Pa; the HydroJet mopping system has been improved for a more powerful, hygienic clean; the 8-in-1 docking cleaning station has been updated; and it adds AI navigation technology.

However, in practice, the E35 seemed almost overloaded with features - so much so that the mapping was inconsistent and the navigation was unreliable a lot of the time. This limited the hands-off experience I need from a robot vacuum, and I didn’t encounter it at all with the E25. Because of this, I’d personally stick with the older model if you’re an average household that doesn’t require a deep clean every time.

It’s also worth comparing the Anker eufy Robot Vacuum E35 with another model with nearly identical specs and features: the Roborock Qrevo Edge 2 Flow Robot Vacuum. Both robot vacuums offer 35,000Pa of suction, impressive edge cleaning, and a sleek, compact look that fits easily in any home.

The downside of the Roborock is that the app is much fiddlier than the Anker eufy app, but their cleaning power is virtually the same. And the Roborock’s navigation ability was miles better than the eufy. So, it depends on what you want from your robot vacuum.

If you want an easy-to-use model that won’t confuse you - even though the navigation will - the E35 might suit you better. If you’re willing to take some time to get to know the app for a consistent and clear clean every time, the Roborock is your best bet… and it’s slightly cheaper.

Verdict: Should you buy the Anker eufy Robot Vacuum E35 Omni?

After loving the E25 so much, I went into testing the Anker eufy Robot Vacuum E35 Omni with very high expectations - which is perhaps why it disappointed me in some ways. However, it’s not a bad robot vacuum. It’s just not perfect, and not what I’d expect from a model with these specs.

Its shining glory is the cleaning quality, with strong suction power and impeccable mopping that truly did leave my floors spotless. In fact, I can confidently say that it left my floors cleaner than 99% of the robot vacuum cleaners I’ve tested. The easy-to-use, customisable app also makes it suitable for robotic newbies and veterans alike.

Where it falls short is the mapping, navigation and overall cleaning routine, though. The E35 Omni regularly seemed to forget where it was or which direction it was cleaning, and the route was never consistent. It also needs to wash the mop multiple times during a single cleaning session, which is something to consider if you have a larger home.

So, it comes down to what you want from your robot vacuum. If you understand that a robot vacuum will never truly replace a regular vacuum and you live in a smaller home, the strange navigation could be a trade-off worth making for the impressive cleaning quality. But if it’s not, the E25 is a solid, reliable choice instead.
