The Dyson V15s won the test field over 400 euros, scoring points in the test above all with the numerous interchangeable nozzles supplied and a very long battery life.

Product details
With the Kärcher FC 4-4 Battery Set 4B-Duo, you can adjust the cleaning position to your floor type and the amount of dirt. For instance, you can increase the speed and water volume for stubborn dirt. Since the electric mop absorbs both dry and wet dirt, there's no need to vacuum before mopping, allowing you to clean faster. The dual water reservoir separates clean and dirty water, ensuring you always use a fresh mop brush. Water consumption is coordinated so that your wastewater tank is only full when the cleaning water tank is empty, preventing unnecessary interruptions in your cleaning task. After use, you can clean the mop brush in the washing machine. With a full battery, you can clean an area of 90 square meters. The cleaning water reservoir has a capacity of 400 milliliters, while the wastewater tank holds 200 milliliters.

The Kärcher vacuum wiper is pleasantly compact and easy to hold. The two wiping rollers run in opposite directions, which should improve the cleaning effect. In the end, however, the result is not quite as convincing. We also find recharging the batteries cumbersome.
This test report belongs to a different type: FC 4-4 Battery Set
Very good94/100
- For the most part "very good" cleaning performance, depending on the respective stains: smooth operation of the model
