MULR-E Water-driven brush

Why clean solar panels? Dust, bird droppings and pollution can reduce energy output by 20-30%. Regular cleaning is essential to maintain ROI. MULTIFIT MULR-E is a water‑driven brush designed for efficient, chemical‑free solar panel maintenance. Powered by clean water, its 550rpm motor drives four oversized PP bristle discs to scrub away dirt without scratching glass surfaces. The carbon fiber telescopic rod (3.5-7.5m) reaches rooftop and ground‑mounted arrays easily, while the aluminum alloy housing ensures long life outdoors. Working pressure 7MPa (max 10MPa) delivers powerful water jet combined with brushing. Optionally pair with MULTIFIT's 2.2kW pump (7MPa, 17L/min). Backed by MULTIFIT’s strong R&D in lightweight, high‑reach cleaning tools, the MULR‑E offers easy operation, lateral force balance and customizable hose length. Keep your solar farm at peak performance – choose MULTIFIT innovation.

Product Features & How to Use – MULTIFIT MULR-E

Features: Water-driven operation – connect to clean water supply, no electricity on the brush. 550rpm motor drives four Φ125mm PP bristle discs for gentle yet powerful scrubbing. Carbon fiber telescopic rod (3.5/5.5/7.5m) with locking device for easy height adjustment. Aluminum alloy housing resists corrosion. Working pressure 7MPa (max 10MPa) removes stubborn dirt without chemicals. Optional 2.2kW water pump (7MPa, 17L/min) for standalone use.

How to use: 1) Attach telescopic rod to brush head, lock desired length. 2) Connect water hose to brush inlet (or pump outlet). 3) Turn on water supply (or start pump). 4) Hold rod and gently move brush across solar panel surface. 5) Water jet rotates brush automatically – no separate motor control needed. 6) Rinse panel and repeat for next section. No chemical agents required – just clean water.
