Roborock F25 Ace Pro test: Foam instead of hot steam?

The F25 Ace Pro is not “yet another vacuum cleaner with more wattage”, but its main feature is clearly jet foaming. In other words, foam that sticks to the floor instead of water running off immediately or being swallowed directly by the roller. At the same time, Roborock packs a real punch in the data sheet. 25,000 Pa suction power, 30 N downward pressure and 430 RPM at the roller are announcements. Above all, we wanted to know how it feels in real use, how easy it is to set up and use the app, whether the station really takes work off your hands – and whether this foam idea really has any added value.

Assembly and scope of delivery are pleasantly quick

With many vacuum cleaners, the start is more like “first plug it together, then understand it and then charge it”. Of course, the F25 Ace Pro doesn’t reinvent the concept, but everything went super fast. Snap in the handle, insert the roller, fill the tanks, place in the station – done.

At first glance, the station may seem rather unspectacular, but it fulfills its purpose. Everything is well thought out without looking like random accessory bingo.

The fact that replacement filters and cleaner are included is just the icing on the cake that makes unpacking a pleasure. You can get started straight away and still have a spare part in stock if you need it or the rinsed filter needs to dry.

App convenience & control: Intuitive, versatile and remote control as a bonus

The app setup went smoothly. Switch on the device, pair it, set up Wi-Fi – done. The interface is pleasantly clear, you quickly find your way around and after a few minutes you have the feeling that everything important is where you expect it to be.

The mode and care settings are particularly practical. Depending on the mode, you can adjust the suction power and water level; in addition to Auto, there is also Eco and Sponge mode. Floor drying can also be activated if you want to “dry” more quickly after mopping. The station also goes into detail. The temperature and intensity of the self-cleaning function can be configured and you can also specify whether it starts automatically after docking. For drying, you can choose between quick-drying or low-noise mode, also with an auto option if you simply want to let the process run through.

Another exciting feature is the remote control app, which allows you to control the vacuum cleaner from your sofa. It works well forwards and you can also steer. In reverse, however, it’s a bit awkward and feels more like stop-and-go than clean maneuvering. Nevertheless, the feature is practical if you want to maneuver under a low bed, for example, without having to lie down. This is where the FlatReach 2.0 concept comes into play: the vacuum cleaner can be made completely flat (180°), but requires a good 12.5 cm of space in height. This is enough for a lot of furniture, but is also the limiting factor for very flat sofas. However, we would not describe the control via app as a truly unique selling point.

Handling, weight and SlideTech 2.0 feel modern

With water in the tank, vacuum cleaners are simply not lightweight. This is exactly where the drive support comes in. SlideTech 2.0 is designed to make pushing and pulling noticeably easier and dynamically adjusts the support.
In our test with the Roborock F25 Ace Pro, this is actually comfortable because the vacuum cleaner feels less “sluggish” – especially when changing direction and pulling back.

On the other hand, there is no ramp for entering the station. You have to lift the appliance to place it neatly in the base. That sounds banal, but it’s a comfort detail that you would have expected from a station that otherwise automates a lot.

No LED at the front, and yes, you can tell

One detail that is unfortunately still often neglected in this price segment is the lack of front lighting. In practice, this means that dust in dimly lit corners or under furniture is simply overlooked. In view of the otherwise very advanced technology package of the Roborock F25 Ace Pro, this saving in the wrong place seems out of place.

Jet foaming in practice: good idea, but not “instant”

The main feature of the F25 Ace Pro is jet foaming. The idea behind it definitely makes sense: very little cleaning solution is used to produce dense foam that adheres to the floor instead of running straight off or being sucked up again immediately by the roller. This gives the foam more time to dissolve dirt.

In the test, the whole thing basically worked well. What we noticed, however, was that the foam comes with a slight delay. You press the pistol grip and it takes a short moment for the foam to actually come out. Similarly when you let go – the foam doesn’t stop immediately. It’s not the end of the world, but if you really want to apply the foam precisely, you’ll notice that you’re lacking some control. This is hardly noticeable when wiping large areas, but it is slightly annoying for specific spots.

Cleaning performance in the test with ketchup, coffee, fluff and animal fur

For the practical test, we deliberately put together a mix that corresponds to everyday life. Ketchup, coffee, coffee grounds, fluff and animal fur – in other words, quite different challenges that a vacuum cleaner has to overcome in a normal household.

The appliance was really strong with lint and animal fur. Pet owners in particular know the problem: hair and fluff is spread everywhere and can get caught in rollers. With the F25 Ace Pro, there was no sign of this. Hair was reliably picked up and ended up in the dirty water tank instead of getting caught in the roller. Even after several passes through our test area – including a fair amount of animal fur – the roller remained clean. No annoying pulling out of knotted hair after mopping.

Coffee grounds were the next candidate we were a little skeptical about. After all, you might think that the fine particles would get stuck in the roller. But this was actually not a problem. The F25 Ace Pro picks up coffee grounds cleanly without anything sticking stubbornly in the roller. After the test, we checked the roller – no residue, no blockages.

The appliance also coped with spilled coffee as a liquid without any problems. The suction power is sufficient to absorb the liquid quickly.

Things got really exciting with ketchup. This is where the difference between “normal” and “major” accidents becomes clear. A blob of ketchup, like the one you spill when eating, can be convincingly cleaned up by the vacuum cleaner. You go over it once or twice and the spot is clean. It’s a different story when a lot of ketchup lands on the floor at once – let’s say a big puddle like the one that forms when something goes wrong when you’re barbecuing or cooking.

This is where you realize that the viscous consistency is a challenge. You have to move it back and forth several times because the roller first moves the ketchup a little before it absorbs it completely. This is not a problem and is not unusual for vacuum cleaners in general – viscous dirt is simply more difficult to handle than liquids or dry dirt.

You should just know that: With a lot of tough dirt at once, it’s just not “once over and done”, you’ll need a few more attempts. But the result in the end was good – the floor was clean.

JawScrapers and hair: the concept fits with what we saw

According to Roborock, the fact that hair and animal fur worked so well is down to the JawScrapers. The anti-tangle concept with shark tooth blades is designed to catch hair early and keep the roller hair-free. Whether this works exactly as described from a technical point of view is not something we are able to verify down to the last detail – for this, the roller would have to be analyzed under a microscope during operation.

But what we can say is this: The behavior in the test basically fits the idea. Animal fur and fluff were picked up very well, and even after several test runs, there was no noticeable amount left in the roller. The system therefore seems to work.

Station, self-cleaning and drying: fast, but not without catches

The base station is almost half the battle with such appliances, as it determines maintenance and odor issues. Roborock relies on high-temperature self-cleaning up to 95 °C and additional hot air drying with 95 °C airflow, including 5-minute quick drying and a quiet 30-minute cycle (48 dB).

In practice, we liked how quickly the station cleaning runs through when using “Quick”. With quick drying activated, it took us around 35 minutes to complete the program. This takes away a lot of the typical “after the mopping comes the tinkering”.

The catch, however, is the energy consumption. While cleaning and drying are running, the station consumes so much energy that charging the battery doesn’t keep up. On the contrary: the battery even loses charge during the station program. This becomes really problematic when the battery drops below 25% – then the station simply stops the program because there is not enough juice. This happened to us twice during the test.

In concrete terms, this means that if you want to start again straight after mopping, you first have to wait until the battery is charged. The station does a great job of cleaning and drying, but you can’t assume that the appliance will be ready for use again immediately afterwards.

Runtime and modes: Eco is long, Max is a short session

The manufacturer claims up to 60 minutes in Eco mode. That sounds good on paper, and tests have shown that this figure is realistic – at least if you are really using Eco mode and not constantly switching back and forth between modes.

In practice, of course, the runtime depends heavily on which mode you use. In Auto mode, which adjusts the power depending on the degree of soiling, you get around 40 minutes. This is usually enough for an average apartment with 70-80 m². In Max mode, when you want full power, the runtime shrinks to around 30 minutes. That’s not a lot, but it makes sense for heavily soiled areas or larger ketchup accidents.

The question is: How often do you really need Max? Auto is perfectly adequate for most everyday situations. However, anyone who frequently covers large areas in one go and likes to be on the move with maximum power at all times will reach the limits of any battery system – the F25 Ace Pro is no different. Then you have to charge in between or work in two stages.

As far as charging time is concerned: a full charge takes around 4-5 hours. That’s okay, but not outstanding. So if you want to carry on working straight after a session with an empty battery, you need patience.

What remains as an impression

The Roborock F25 Ace Pro is technically a very modern package. The cleaning performance is right, the edge cleaning on three sides works better than with many competitor models, and the station with hot water self-cleaning really takes the work out of cleaning. We were particularly impressed by the results with animal fur and fluff – the roller had no problems here, even after several passes. The edge cleaning is also really powerful, leaving significantly less dirt than usual.

The jet foaming function is an interesting idea that can certainly help with stubborn stains. However, we were annoyed by the delay when spraying – the foam does not appear immediately when you press the trigger and does not stop immediately when you let go. This takes away some of the precision of the feature if you want to work in a targeted manner.

Where the F25 Ace Pro disappointed us: The lack of LED at the front makes it difficult to see debris in dark corners or under furniture. The station does not have a drive-in ramp, so you have to lift the appliance – this is now standard with other appliances in this price range. However, the biggest point of criticism is the station’s energy management. While cleaning and drying are running, the battery discharges instead of charging. If the charge falls below 25%, the station simply stops the program. This happened to us twice during the test and is really annoying if you want to continue straight away.

Overall, the F25 Ace Pro is a powerful vacuum cleaner with strong core functions, but it falls short when it comes to comfort details. If you are looking for a vacuum mop that is convincing on edges, animal fur and mixed everyday dirt and you can live with the weaknesses mentioned, you will get a solid appliance here. If you expect maximum ease of use, flawless energy management and precise foam dosing, you should also look at alternatives – or hope for a software update that will at least get the battery problem under control.

The Roborock F25 Ace Pro impresses with its powerful cleaning performance, excellent edge cleaning and a station that takes care of a lot of maintenance with hot cleaning and drying. The jet foaming function is an interesting addition, but reacts with a slight delay in practice. Minor weaknesses such as the lack of LED lighting, the battery problem during station cleaning and the lack of a drive-in ramp only slightly spoil the otherwise very good overall impression.
