Questions & Answers about Fontus

MyBosch offers an extended warranty period of 3 instead of 2 years on your newly purchased Bosch DIY power tools, garden tools or measuring tools. 

The Fontus is a low pressure cleaner specifically designed to tackle small to medium sized cleaning tasks around the home and on the go. It has an integrated water tank and an 18V lithium-ion battery, making it completely independent of mains water and electricity.

An Aquatak High-Pressure Washer is needed for larger cleaning tasks where high-pressure and high water flow is required, such as cleaning patios, decking, drive ways, cars. A high-pressure washer will require mains electricity and mains water.

The 18V Bosch lithium-ion battery has to be removed from the machine and placed on the charger. The flashing of the battery charge indicator signals the charging procedure. Continuous lighting of the battery charge indicator indicates that the battery is fully charged.

The battery run time of the Fontus depends on the pressure mode and spray pattern used.

The maximum run time of up to 60 minutes is achieved when the Fontus is in the low pressure mode and the shower spray pattern is in use. 

The minimum run time of 15 minutes is achieved when the Fontus is in the turbo pressure mode and the pencil spray pattern is in use. 

The rate the water is used depends on the pressure mode and spray pattern selected. The higher the flow rate, the quicker water is used up. Maximum time is 9 minutes. Minimum time is 5 minutes.

The machine is designed to switch off the pump as soon as the spray gun trigger is released. The pump also shuts off after 20 seconds when it detects that water has run out.
If the machine has not been used for 5 minutes, it turns itself off to preserve battery life.

Yes, however, if hot water is used it should not exceed a temperature of 50°C.

Yes, use water from a water source such as water butts or lakes to fill up Fontus. There is a filter in the water tank, which ensures that debris and dirt will not enter the pump. However, salt water should not be used to fill the tank. Do not immerse Fontus into the water source, as this will damage the product. A filling device such as an outdoor tap or a jug must be used when filling up the tank.

Adding detergent to the water tank is not recommended.

When in use, the product must be in an upright position. However, when in transport (i.e. a car), the product can be laid on its back.

Switch the tool off and press the trigger to drain the remaining water from the hose. Then disconnect the hose from the spray gun and water outlet. The spray gun, brush and hose can be stored within the machine. The battery should then be removed ready for storage.
