NOT A REVOLUTION, BUT THE PERFECT EVOLUTION OF THE BEST TECHNOLOGIES

The F25 Ace represents the top of the range in Roborock’s new series of floor washers. In the table below, you can see the differences between the various versions. Additionally, two Combo versions will be available, which can be used both as floor washers and vacuum cleaners.

At NonSoloRobot, we tested the F25 Ace in advance, and we want to share what impressed us—strengths and weaknesses included—always keeping a close eye on the real needs of the end user.

Design and Technology

For those who have never used a device like this, it is a floor washer capable of vacuuming and washing simultaneously, cleaning the roller with fresh water while suctioning dirty water. The sector is constantly evolving, but brands often chase new features without perfecting existing technologies. The F25 Ace does exactly the opposite: it does not introduce revolutionary features but optimizes and combines the best of what is already available—without compromises.

Power is not lacking: 20,000 Pa of suction, a roller spinning at 450 RPM, and 20N of pressure on the floor. The result? Effective cleaning on the first pass, without leaving streaks.

Aesthetically, it stands out for its elegant design and quality finishes. Weighing 4.7 kg, it is lighter than average. Thanks to the water tank positioned above the wheels rather than in the main body, the perceived weight during use is reduced. The tank has a capacity of 740 ml and includes a 100 ml automatic detergent dispenser.

The head rotates up to 70°, ensuring excellent maneuverability. The SlideTech 2.0 system, with dual independent brushless motors, improves movement fluidity: each wheel independently detects thrust and direction, adjusting to prevent slipping on floors. FlatReach® 2.0 technology allows the vacuum cleaner to tilt to 180°, reducing its height to just 12.5 cm—making it perfect for cleaning under furniture, beds, and sofas.

Performance in Action

During our tests, the F25 Ace proved effective against solid dirt, liquids, pet hair, and stubborn stains. Edge cleaning is excellent: Roborock claims less than a 1 mm gap from the baseboard, and in our tests, it indeed turned out to be the floor washer that gets closest to the edges.

I was pleasantly surprised to find that in Max mode, it even reaches the grout lines, which remain wet after cleaning—something most floor washers fail to do.

The only downside? The lack of an LED light to illuminate under furniture, probably sacrificed for the tank’s positioning. However, the advantage of a tank on the wheels (better handling and balanced weight) more than makes up for this absence.

The newly designed bagged battery ensures up to 60 minutes of operation in Eco mode, covering up to 410 sqm, according to Roborock.

Self-Cleaning and Smart Drying

One of the most annoying aspects of floor washers is maintenance, but Roborock has done a great job minimizing user effort.

After each cleaning session, the roller is automatically washed and dried at 90°C, preventing unpleasant odors. Drying can be set to silent or fast mode (5 minutes).

But the F25 Ace’s self-cleaning goes further: the proactive system automatically adjusts washing modes and times based on the amount of dirt detected by the DirtTect® sensor. The same sensor, in automatic mode, optimizes suction, roller speed, water, and detergent amounts—avoiding waste.

The automatic detergent dispenser provides up to 30 days of autonomy, though it lacks an indicator to signal when the liquid is running low (fortunately, the tank is semi-transparent, so it’s easy to check).

An interesting detail: the system also dries the filter and dirty water tank, something we have never seen in other floor washers.

Solid-Liquid Separation System

Everything the F25 Ace vacuums is collected in a 720 ml container with a three-stage separation system: solid-liquid-air. This system not only allows the device to tilt 180° without filling restrictions (unlike other products) but also prevents solid debris from mixing with liquid dirt.

One of the most common issues with these devices is hair and fur accumulating on the roller. Roborock solved this with a constant-pressure scraper that evenly squeezes the roller and shark tooth blades that remove hair and fur—ensuring optimal roller cleaning.

Customization and App Control

For a personalized experience, the F25 Ace offers four operating modes:
✅ Eco: minimal water, detergent, and battery consumption.
✅ Auto: intelligent management, with customizable settings in the app.
✅ Max: maximum power for deep cleaning.
✅ Sponge: mode for absorbing large amounts of liquid.

The integrated display shows:

WiFi status
Selected mode
Dirt indicator (blue to red depending on detected dirt level)
Battery level (I would have preferred a percentage instead of bars.)

Through the Roborock app, you can:
✅ Adjust wheel traction.
✅ Customize self-cleaning and drying.
✅ Modify volume and language of voice alerts.
✅ Monitor consumable wear.
✅ Update firmware.
✅ Access manuals and useful information.

A cool feature is remote control, which allows you to move the floor washer while it’s lying flat—useful for cleaning under beds without kneeling.

I noticed that, unlike other models, the F25 Ace does not automatically pause when placed upright—hopefully, this will be added in a future update.

Thanks to its extreme customization, I was able to perfectly adapt the floor washer to both parquet, which is a very delicate flooring—by reducing the roller speed and water flow—and the rustic tile flooring on my ground floor, where I could adjust the water and detergent levels, suction power, and roller speed to the appropriate settings.

Conclusion

The Roborock F25 Ace is not a revolution, but it is the result of excellent refinement work. It is a mature, reliable, and high-performance product that stands at the top of its category.

At NonSoloRobot, we recommend it: among the floor washers currently on the market, it is one of the most powerful and complete, adaptable to many cleaning scenarios and every household situation.
