Very good80/100

Terrace, bicycle or camping: with the Bosch Fontus you can remove light dirt without electricity or water. With 20 bar pressure, the device is no substitute for a high-pressure cleaner. The plastic hose connection is a weak point.
With a maximum pressure of 20 bar, the cleaning performance is below the average of traditional pressure washers and is primarily suited for delicate surfaces.
The built-in container holds 15 litres of water, allowing the device to be used on the go in locations without a direct water supply.
