Aluminium water fed pole is a lightweight, cost-effective telescopic hollow pole designed for professional outdoor window and facade cleaning. Made of high-grade aerospace aluminum alloy, it combines light weight with strong structural rigidity, anti-corrosion and bending resistance. The hollow inner channel delivers purified water steadily to the top cleaning brush. Multi-section telescopic structure allows flexible height adjustment for cleaning low-rise homes, storefronts and mid-rise building windows. Safe ground operation replaces risky high-altitude work, and the durable sealing structure prevents water leakage during long-time continuous cleaning.
