Delicate surfaces such as windows or solar panels require a correspondingly gentle cleaning method to avoid damage. The brush features soft and split bristles that protect the sensitive glass while still providing a thorough clean—either with pure water or high pressure. It can be easily and quickly mounted directly onto a water-fed telescopic pole or a high-pressure lance. A nozzle set for pure water and a high-pressure nozzle with a 25° angle ensure both application options.
