Roborock F25 Steam Test: Steam Melts Stains and Battery Life

Summarizing, some floor-washing vacuums simply clean the floor with cold or hot water, while others offer a steam mode to thoroughly loosen dirt from tile or parquet. This is precisely what the Roborock F25 Steam adds to the line launched last year by the manufacturer.

Launched in the summer of 2026, this newcomer in the line, priced at €589, uses steam to lift ingrained stains. The advertised 180 °C refers to the temperature measured at the exit of the internal heater, and not at floor contact. The 180° are also embedded in its design, enabling it to lie flat to pass under some furniture. The question remains how it differentiates itself from the F25 Ultra, which also offers steam. The Steam omits cleaning floors with hot water but promises stronger suction and better Eco autonomy. Is a new device justified? The answer in our test.

Design and Ergonomics

In terms of aesthetics, the Roborock F25 Steam preserves the silhouette of the F25 line, with its clean-water reservoir placed very low, matte plastic and translucent reservoirs. Build quality is solid; the device does not creak and does not feel weak. The only drawback is that the upper part of the clean-water reservoir is very susceptible to fingerprints and dust.

Weighing 5.6 kilograms, it isn’t feather-light. Nevertheless, its very low center of gravity and the forward-rolling wheel make it easy to maneuver. The device offers driven wheels, simplifying its use.

Another advantage is its 180° tilt, allowing it to lie completely flat. Perfect for cleaning under furniture that isn’t too low, such as a bed, a TV stand, or a legged shelf. However, it will not pass beneath all furniture, far from it.

On the front, a blue LED, especially useful in dark zones, helps facilitate picking up dust of all kinds, sometimes barely visible.

The vacuum is controlled with three buttons on the handle, with a display on the motor block showing battery level, steam status, and especially the selected mode. There is no app. This avoids creating an account, a login, and linking a smartphone to a handheld vacuum.

On the front, a blue LED, especially useful in dark areas, helps facilitate collecting dust of all kinds that can be hard to see.

The vacuum is controlled with three buttons on the handle, with a display on the motor block that shows the battery level, the status of the steam, and above all, the selected mode. There is no app. This saves you from creating an account, signing in, and pairing a handheld vacuum with a smartphone.

The docking station is flat and discreet. The station stays compact; it automatically cleans the steam roller and hot-water roller, then dries it. The dirty-water container includes, as usual, a removable separator to separate out larger elements, to separate them from the rest. It is strongly recommended to rinse it after each use.

Washing performance

At first glance, the differences with the previously tested F25 Ultra aren’t numerous. Yet the F25 Steam does indeed offer slightly different performance. The suction power on this model is 25,000 Pa, allowing it to collect the vast majority of dirt and dust on the floor.

The steam works properly and removes stains on the floor, including grease stains. It is also effective on coffee stains, softening them as it passes. However, it is far from indispensable everywhere. The other washing modes are usually sufficient for daily cleaning. The roller, which Roborock attributes a pressing force of 33 N, handles lightly ingrained stains without needing to go back over the same area three times.

Overall, it sucks up everything in its path, from crumbs to dust, nearby cat food, and even spilled liquids.

On the sides, Roborock promises to get within 1 mm of the skirting boards. While this value is hard to measure precisely, we observed effective edge cleaning, collecting the vast majority of dust and dirt along the edges. The result is satisfactory, though not perfect, as is the case with the vast majority of competitors in this range.

Two caveats to add, though. The F25 Steam captures waste well in forward motion, but is noticeably less convincing in reverse. Also, in steam mode, you can observe some marks on glossy tiles. A quick switch to the “Sponge” mode can address the issue quickly, but requires a mode change.

On the front, a blue LED, particularly useful in dark areas, helps facilitate gathering dust of all kinds, sometimes barely visible.

The vacuum is controlled with three buttons on the handle, with a display on the engine block that shows the battery level, the steam status, and especially the selected mode. There is no app. This avoids creating an account, a login, and a double control of a handheld vacuum with a smartphone.

The dock remains compact; it cleans the steam roller and the hot-water roller automatically, then dries them. The dirty-water tank includes, as always, a removable separator for the larger elements, to separate them from the rest. It is strongly recommended to rinse it after each use.

How to maintain my F25 Steam?

Once it is resting on its base, pressing the dedicated button starts a very thorough cycle: rinsing the circuit, treating the roller with steam and hot water, rotating in both directions, wringing, and finally drying with hot air at 95 °C.

A dedicated sensor, cleverly named DirTect, prolongs the washing of the roller as long as the water runs cloudy. Regarding drying, a quick 5-minute mode is offered, but it is noisy. A 30-minute silent mode, indeed longer, but significantly more discreet, is also available.

Nevertheless, it is essential to empty the dirty-water tank after every cleaning session. Preferably, once the device has finished its automatic cleaning cycle, to avoid unpleasant odors.

Among other manual maintenance tasks, weekly filter cleaning seems prudent, and running a brush through the suction duct from time to time never hurts. Regarding detergent, Roborock offers its own products to be poured into the dedicated reservoir only. The detergent is not essential for daily cleaning: the device can also operate with tap water alone.
