Roborock F25 Ultra: two-minute review
The Roborock F25 Ultra is a premium cordless upright wet-and-dry cleaner that seeks to outshine the competition with its three USPs: a sanitizing steam function, grease-busting hot water mopping and adjustable power-assisted wheels.
Although rather heavy, the power-assisted wheels make the F25 Ultra super-easy to drive, and you can even hook up the companion app, lie it down and remote-control it under low-slung furniture if you desire. Once you’re finished cleaning, a thorough self-cleaning mode takes care of the majority of maintenance. All the user has to do is periodically empty the contents of its dirty water tank into the toilet bowl.
While I would have preferred a full-width roller for true edge cleaning, the F25 Ultra is an excellent performer in all disciplines. Whether all this state-of-the-art tech is worth the asking price is open to debate but I’m personally very much smitten.
Roborock F25 Ultra review: price & availability
- List price: $599.99 / AU$1,499
- Launched: Fall 2025
- Availability: US and Australia
The Roborock F25 Ultra was unveiled at IFA in September 2025, and is available to buy in the US and Australia. At time of writing, the Roborock F25 Ultra isn’t available in the UK or Europe but I suspect it’ll be launched this side of the Atlantic in due course.
At full price, it costs $799.99 / AU$1,499 – although I’m not sure it’ll be sold at that price very often, because while I’ve been writing this review I’ve seen it for $599.99 and $549.99 in the US, and AU$899 in Australia. It’s available to purchase direct from Roborock as well as via a range of third-party retailers, including Amazon.
That’s quite a slice of cash for a hard floor cleaner given that you can find something similar without the bells and whistles for substantially less, including Roborock’s base-level F25 LT which comes with the bare essentials like standard mopping and a slightly lower suction power of 20,000Pa.
Nevertheless, if you want a true state-of-the-art hard floor cleaner that covers all bases from sucking up spills to hot water mopping and hygienic steaming, the F25 Ultra is most definitely worth splashing out on.

Roborock F25 Ultra review: design
- Hot water mopping and new steam function
- Power-assisted wheels and the ability to remote control via an app
- LED headlamps, and can lie flat to the ground
I always get a bit excited whenever Roborock announces a new product (this brand makes some of the very best robot vacuums I’ve tested) and, believe me, this new addition to its F25 range of hard floor cleaners is definitely cause for a spot of childlike jumping up and down.
But it wasn’t always like this. I remember Roborock’s first attempt at making a hard floor cleaner. It was called the Dyad and it wasn’t great, it must be said, mostly because it was cumbersome, difficult to maneuver, and it couldn’t stand up on its own. I’m sure the latest range of Dyads have improved but I still can’t see them holding a candle to the newer F25 range.
I’ve already tried out the Roborock F25 ACE, but this newer model excites me even more because it comes with a 356F / 180C steam function and hot-mopping feature. These are a godsend for blitzing ingrained stains that most hard floor cleaners’ standard mopping functions may have trouble removing.
While it’s difficult to muster up much enthusiasm about the styling of most wet-and-dry cleaners, for my money the models in the F25 range are the best lookers I’ve laid eyes on in a long time. Nevertheless, it’s what goes on beneath the skin that matters most and in this regard the F25 Ultra trounces much of the opposition by dint of its three main USPs: the aforementioned steam function, the newly added hot mopping option and its adjustable power-assisted wheels.
But before I discuss these in detail, let’s take a closer look at the design, starting with the floorhead. While the F25 Ultra’s 720ml dirty water tank is housed on the main body like most wet-and-dry models, its fresh water reservoir is positioned lower down on top of the brushhead housing, and this not only lowers the weight on the handle while providing instant line-of-sight to its water level, it also reduces the body’s overall profile which means it can be lowered parallel with the floor for reaching deep under low-slung furnishings like sofas and beds. In fact, there’s a tiny wheel behind the handle section for this purpose, but more on that in a moment.
The 870ml clean water reservoir features two sealed fillers, one for fresh water and a much smaller one for adding the contents of Roborock’s supplied 200ml bottle of floor cleaning solution. Both liquids are mixed automatically during cleaning and you’ll be pleased to learn that the floor solution lasts for many cleaning sessions. To fill the fresh water tank, simply grab its rose-gold handle while pressing on a latch behind to lift it off its plinth.
The F25 Ultra’s floorhead measures 10.5in / 26.6cm in width. However, the cloth roller itself measures 9.8in / 25cm with 0.4in / 1cm of space at one outer edge and 0.2in / 0.6cm at the other. That’s par for the course for most models of this nature, but I recently reviewed a Eureka RapidWash 730 that uses a split roller that runs the full width of the housing, even protruding a couple of millimeters beyond the housing on one side. I’d like to see other manufacturers adopt this innovative approach because it allows for cleaning right to the very edge.
According to the product blurb, the F25 Ultra’s brush housing is equipped with 32 outlets for heating the water to 187F / 86C as it hits the roller, and six steam outlets delivering a volume of 2,000mg/min at a whopping 356F / 180C. The roller itself exerts a force of 33 Newtons – equivalent to 7.4 lbs / 3.36kg of deep scrub-ability – while a pair of ‘jaw scrapers’ behind the roller help keep the floor streak-free and the roller tangle-free. The floorhead also has a set of bright LEDs that emit a purple hue for cleaning the darker recesses of a home.
The F25 Ultra comes with four main cleaning modes – Sponge, Auto, Steam and Hot Water. All modes are accessed via the mode button positioned on the main handle, along with the on/off button and another button for selecting the self cleaning function when the unit is placed in the charging dock.
Although confusingly named, Sponge mode is for sucking up large liquid and debris-based spills so you don’t have to get down on hands and knees with a handful of paper towels. This single suction task is one of the main reasons why these wet-and-dry machines are so popular. Spilt bowl of cereal or bowl of soup? Check. Small water leak around the sink? Check. Dog sick in the kitchen? Check. You get the gist.
In Auto mode, the F25 Ultra uses a sensor to detect dirt and automatically adjust cleaning intensity to clear it. This mode leaves only a thin veneer of dampness in its wake and is the best option for light day-to-day mopping duties. But when the going gets tough, you also have the option of either hot water mopping or, for deep down germ-killing cleanliness, the power of steam.
In fact, you can tell that the machine is steaming because there’s a plume of the stuff wafting up from the front like some special dry ice effect at a rock concert. According to Roborock, this steam function is also suitable for use on wooden flooring and I second that because I detected no tell-tale signs of damage on my floors.
If you find pushing and pulling vacuum cleaners around a bit of a workout, you’ll love this model’s adjustable power-assisted wheels. With a brushless motor in each wheel and some AI-enhanced tech to govern it all, Roborock’s SlideTech 2.0 system functions like a power-assisted electric bicycle. As soon as you push or pull the cleaner, the wheels instantly provide a level of self-propulsion that feels extremely natural while making the unit feel really light in the hand.
The adjustable power assistance also applies to the turns, giving the F25 Ultra the ability to effortlessly glide around furniture and walls with 70-degree steering. And unlike its predecessor, the F25 ACE, the motorized wheels are disengaged the moment you stand it up.
Couple this dextrous motorized ability with the wherewithal to remotely control the F25 Ultra via the excellent Roborock app and you have a hard floor cleaner that you can quite literally drive under the entire length of a super king bed by lowering the handle to the floor and steering it using the app’s virtual joysticks.
Whenever you have finished a task, simply place the unit into its square tub-shaped dock and tap the self-clean button on the vac’s handlebar to automatically engage the cleaning process which washes the roller and areas around it with hot water at temperatures between 194F and 356F (90C to 180C) before drying the roller with hot air at a substantial 203F / 95C. When it’s finished cleaning, chuck the contents of the F25 Ultra’s dirty water tank into the toilet bowl.
The Roborock F25 Ultra weighs 11.46 lbs / 5.2kg which is about average for a hard floor cleaner. While it’s light enough for most able bods to haul up a flight of stairs, a carrying handle on the rear wouldn’t have gone amiss.

Roborock F25 Ultra review: performance
- Stupendous suction power sucks up solids and liquids easily
- Groundbreaking steam function clears even dried stains
- Very easy to push, pull and maneuver
I tested this model in a number of disciplines. Firstly, I used it as a bog-standard mop on my engineered wooden flooring and was pleasantly surprised by how little water it left behind – just a thin perfectly uniform film with no streaking or signs of missed areas.
Some models I’ve tested have had a habit of leaving a small pool of water around the roller when turning the unit off. But, like the Eureka SpeedWash 730, this model gave a quick blast of suction just before it switched itself and I have no pools of water to report. I’m happy with that.

My second test was using the Sponge mode to collect a nasty spill using a variety of wet and dry ingredients, including oats, ketchup, milk, a crushed biscuit and an egg for extra grunginess. Cleaning up something as disgusting as this the conventional way involves a pile of paper towels and a pair of Marigolds. But not with this gunk swallower, which I would say performed better than any model of this nature that I’ve so far reviewed. It quite literally sucked up every last vestige of the mess without leaving any sign that anything was there.
All I had to do was unclip the dirty water tank and empty its revolting contents into the toilet. Hint: there’s a recessed yellow handle on top of the firm-fitting dirty water tank that’s designed to release the lid. If you try to force the lid off, there’s a very good chance of spilling everything all over your legs.
For my third test I switched it to hot water mopping and it took about a minute for the roller to feel warm. While I was a bit nervous of using this mode for too long on my wooden floor (hot water seeps more easily), I was mightily impressed by the results when I tested it on some ingrained stains left behind by the dogs.
My final test used the new steam mopping feature on two patches of dried soy sauce stains on my bathroom’s tiled floor, but they may as well have been wet because the combination of steam and the fast-spinning roller obliterated both stains in a single pass.
It’s good to know that, according to Roborock, the F25 Ultra’s steam function is wooden floor-friendly. My floors are made from engineered wood and I’ve seen no evidence of any harm after using this model’s steam function. (As an aside: the act of mopping wooden floors can leave them looking tired and a bit dull, but I’ve started using Bona Wood Floor Gloss Finish, which works a treat to counter any dryness and leaves a beautiful sheen. Here’s more on how to clean a hardwood floor, if you’re looking for some general guidance).
The Roborock F25 Ultra’s self-cleaning system automatically washes the roller mop in hot water followed by an efficient drying sequence using wafts of hot air to keep odors and mildew at bay.
In terms of battery usage, Roborock states a running time in Auto mode of ‘up to 60 minutes’. I sadly don’t have the floor space to have kept it running in Auto mode till the battery ran out or my wooden floors would have been soaked and possibly damaged. However, I did test both the hot water and steam modes which use a lot more battery power and the hot water function gave me 20 minutes of mopping while the steam function continued to operate for another five minutes. I call that a very decent set of stats and more than enough time to cover three or four average-sized rooms using a mix of all three cleaning functions.

How I tested the Roborock F25 Ultra
I knew what to expect with the F25 Ultra since I reviewed its stablemate, the F25 ACE, earlier this year. Hence putting it all together and setting it up was a breeze.
The first thing I did was let it charge, before taking it for a spin in the kitchen to see how well it performed at general light-duty mopping. I then tried out the hot water mopping function on some dog stains followed by my main suction test using both liquids and solids. Finally, I tried out the steam function to see how well it removed a couple of dried soy sauce stains.
