Using a frequency-controlled high-pressure pump, multiple individuals at the can engage in cleaning services at the same time. With the largest high-pressure pump, it is even possible to spray with ten people at the same time with high pressure.

The high-pressure pumps are frequency-controlled, which means that the pressure gradually increases on the pump. This is better for the motor of the high-pressure pump, but also ensures that the pressure on the arms of the person who uses the foam lance is lower.

Another advantage of the frequency-controlled high-pressure pumps is that all higher-pressure lances and nozzles can be connected to this pump. Where it is very harmful to a normal high-pressure syringe to use a lance or nozzle, which has less spray capacity than the high-pressure pump itself, this is not a problem for the frequency-controlled high-pressure pumps.
