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.
