The manual water spray brush is equipped with a 4.8m-9m telescopic rod, which can be freely extended and adapted to different heights, making it more convenient to store. With tap water or other water supply devices, water spraying and brushing can be realized at the same time to achieve the purpose of efficient cleaning. When there is no water supply device, you can also choose a low-power pump to clean the 12-meter lift, and you can also choose a lithium-ion pump to supply water in an environment without electricity.
