For just £270 at the moment (RRP £360), the Ultenic T20 Pro offers excellent value for money. Sure, it's not the cheapest robot vacuum out there, but when you consider what you’re getting - vacuuming, mopping, a self-emptying station, LiDAR navigation and mapping - it’s a seriously hardworking little gadget for the price.

Performance is good on both carpets and hard floors, and the app is straightforward to connect and use. It also allows for tailored cleaning, with multiple modes and adjustable levels of suction and water flow. While the navigation could be smoother, it generally does a good job in this area. And even better, you can go up to 10 weeks before needing to empty the dustbin - though some fortnightly maintenance, like cleaning the brushes and water tank, is still required.

Bottom line: It’s not without its quirks, but given the value on offer, it’s a handy little gadget that delivers that priceless ‘keeping on top of things’ feeling.

How easy was the Ultenic T20 Pro Robot Vacuum and Mop to set up?

Setting up the T20 Pro was nice and easy. After clipping the main brush into place and giving it a full charge, it connected to the Ultenic app in just a few minutes. It then whirred off on its first mapping run, tracing the layout of my floor. Once that was done, it was ready to start cleaning.

On first impressions, the docking station is relatively small and compact. While there’s no separate base for the vacuum itself - so the robot does stick out slightly - it’s still much more compact than some of the larger stations I’ve seen and it fit neatly into my home.

It's worth noting that Ultenic recommends you complete three dry runs on the vacuum only mode before it can start mopping, so I left the water tank empty during those initial cleans.

What’s the Ultenic T20 Pro Robot Vacuum and Mop like to use day-to-day?

The T20 charging on its docking station (L) and cleaning multiple surfaces (R)

Before setting the T20 off, it’s definitely worth doing a quick tidy - like all robot vacuums, it’s smart, but not that smart. Stray socks, cables or the odd trainer can still confuse it, so a quick pre-clean clear-up helps it do its best work (and saves it from chewing on your phone charger).

Once it’s set up, the T20 is fairly easy to operate. The app’s interface is intuitive and gives you plenty of control - from scheduling regular cleans to creating room partitions and no-go zones. I found the no-go zone particularly handy for under the bed, which definitely needs a proper clear-out before any robot goes near it! I also loved being able to schedule daily cleans, so my flat stayed tidy without me lifting a finger.

There are a few cleaning modes - vacuum only, mop only, or vacuum, sweep and mop combined - plus options for different cleaning areas (partition, area, and spot). You can even tweak the suction power and water flow across three levels each, which is a nice bit of customisation for a budget vacuum.

One clever touch I loved was being able to choose how many sessions it completes before emptying the dustbin. It’s a noisy process (I definitely wouldn’t schedule it during a meeting), but still quieter than some pricier models like the Eufy E28. And speaking of noise, it’s not whisper-quiet in general - I had to nudge up the TV volume when it was on - though eco mode is noticeably softer than full power.

Adding water for mopping is simple thanks to the removable tank, though at just 250ml, it does need topping up fairly often. The narrow opening for the water also means pouring can get splashy unless you use a jug. Since the mop heads don’t self-dry, if you run the T20 in vacuum-only mode shortly after mopping, the damp pads can leave a bit of a trail - so you may want to swap them over between cleans to avoid this.

The T20 even talks to you occasionally - chirping up to tell you “water tank removed” - though its robotic voice can sound a bit unclear. Still, for the price, it’s an impressive little cleaner that keeps on top of daily mess with minimal effort on your part.

How is the Ultenic T20 Pro's navigation and mapping?

The T20 Pro isn’t the slickest navigator I’ve tested, but the AI-powered LiDAR technology gets the job done well. It cleans in a methodical zig-zag pattern, tackling edges first, with good coverage across the area.

Obstacle avoidance is generally reliable - in cleaning mode, it gracefully dodged a pair of slippers I left out as a test - though it can be a little inconsistent. Out of cleaning mode, on the way back to the docking station, it knocked the same pair of slippers out of the way. I did notice it occasionally bumped into chair legs or got stuck under furniture, too, but on the whole it navigated around my flat OK.

The spot-cleaning mode was a mixed bag. Sometimes it perfectly tackled a targeted area, but other times when faced with a no-mop zone, even with the water flow turned off, it skipped the no-mop zone or wandered slightly outside the designated space. Without any no-mop zones marked, it performed more predictably, though.

In terms of mapping, the T20 Pro handled my open-plan living and dining room well, creating an accurate map in the app. The kitchen, which is slightly more unusual in layout as it's in the same open-plan space but up a few steps, was scanned beyond the areas it could actually clean - not a problem, but worth noting. It thankfully identified steps well and I never had a mishap where it fell off.

One tip: make sure to save each map as you go. I accidentally lost the first-floor map when moving to the living room without saving it first. A 'new map' button would be handy here, but this is a minor issue. Overall, the multi-floor mapping in the app worked well.

How does the Ultenic T20 Pro Robot Vacuum perform on carpets?

The T20 isn’t the most powerful robot vacuum out there - it has 8,000 Pa suction compared to some premium models with 20,000 Pa - but it still did a really good job on my area rug. It cleaned it effectively and left that satisfying freshly vacuumed look. For everyday upkeep, I was very impressed.

In our cereal spill test, it picked up most of the flakes on the first pass, and only needed a second 'spot-clean' run to get the last few crumbs.

Even when using the combined vacuum-and-mop mode, it didn’t leave my rug damp, which was a relief. The only exception was the edges, where it had made the transition from hard floor to carpet - these spots ended up a little wet. After that, to be on the safe side, I set this area as a no-mop zone.

How does the Ultenic T20 Robot Vacuum and Mop perform on hard floors?

The Ultenic facing our cereal spill test (L) and cleaning my tiled kitchen (R)

Very well. The majority of my flat is hard flooring (a mix of laminate and tiles), and the T20 glided across these surfaces effortlessly, picking up everyday dust, crumbs and debris with ease. The mopping function works fine for daily upkeep - floors look cleaner and definitely feel fresher - though it isn't strong enough to tackle dried-on coffee splashes or sticky spots. I also tried the included floor cleaner, which has a bluebell scent, though it was subtle and I couldn’t really detect it once diluted.

In our cereal spill test, cornflakes were mostly collected on the first pass, with only a few small flakes nudged around or left behind. Initially, the side brush did scatter the flakes about a bit, but it cleaned most of them up as it zig-zagged on the floor.

One thing to note, however: unlike premium robot mops, the T20 doesn’t automatically empty or wash its water tank, so you’ll need to rinse and dry the mop head yourself after a few runs. It’s not a difficult task, but it’s worth keeping in mind for regular maintenance.

How does the Ultenic T20 Pro perform on hair?

Really well. While I don't own a pet myself (yet!), I scattered a few clumps from my hairbrush to test it on both my rug and hard floors, and the T20 picked up everything with ease. That said, long hair can get tangled in the roller, and a clump of hair did get caught in the side brush - so a quick tidy-up of the brush afterwards is sometimes necessary.

How is the Ultenic T20's battery life?

No complaints here. The app makes it easy to keep an eye on the battery, and it automatically returns to its dock when running low - though during testing it never actually needed to. As you’d expect, higher suction levels drain the battery noticeably faster than eco mode, but that’s true for any cordless vacuum - robot or otherwise.

It can sometimes struggle finding its way back to the base to recharge, though it always eventually gets there. I found it returned more easily on my upper floor, so this might just be down to the layout or signal in my home.

How easy is it to empty and maintain the Ultenic T20 Pro Robot Vacuum and Mop?

The T20's dust bag is easy to access in the docking station

Emptying the T20 is nice and easy. All the dust collects automatically into a large 3.5-litre bag, which is easy to remove and replace. This keeps everything neat and contained too - ideal for those with allergies. And thanks to its large capacity, I didn't even need to empty it during the two-week testing period (though I did for the sake of the review!).

Ultenic claims it can collect up to 10 week's worth of debris before it needs replacing - something I don't think is an exaggeration. There’s an ongoing cost for replacement bags (£18 for six), but that’s to be expected with a self-emptying robot vacuum.

Maintenance is a bit more hands-on, though. The brushes and dustbin/water tank need cleaning every two weeks - the latter did get a bit grimy during testing. The wheels and sensors also require cleaning once a month, while the filter needs replacing every three months.

The instructions also suggest washing the mop pads by hand - I’d have preferred them to be machine-washable for extra hygiene and ease.

Does the Ultenic T20 offer good value for money?

Absolutely. Even at full price, the Ultenic T20 Pro is a well-rounded cleaner, but at its current sale price of £270, it offers great value for money. It vacuums and mops effectively, maps your home and even includes thoughtful extras like the cleaning solution.

The large dust bag also means you won’t need to empty it for a while, which makes day-to-day use even easier. That being said, the replacement bags are quite pricey, working out at £3 per bag.

How I tested

I put the Ultenic T20 Pro through its paces in my two-bedroom flat in Hertfordshire over a two-week period. Testing included a mix of floor types - laminate, tiles and an area rug - and covered both everyday cleaning jobs and our more specific tests, like cereal spills.

The Ultenic was then scored against MNHQ’s core home review criteria (each marked out of 15):

• Performance

• Quality and durability

• Ease of use

• Value for money

I also rated the T20 out of 10 for these product-specific measures:

• Suction power

• Navigation and mapping

• Versatility

• Ease of emptying

These results were then combined to give an overall score out of 100.
