The FK4 is a versatile and lightweight cleaning unit designed to handle both rooftop and ground-mounted solar installations with ease. Powered by a Honda 4-stroke gas engine, it offers a cleaning capacity of around 440 square meters per hour, making it a practical solution for both professionals and beginners.

Equipped with a single 90 cm nylon 66 brush with a 170 mm diameter, the FK4 delivers effective cleaning while being gentle on panel surfaces thanks to its scratch-proof bristles. Its rust-free stainless steel frame and aluminium protective shell ensure long-lasting durability in all working conditions.

The FK4 can be used in two ways: with a telescopic aluminium pole that extends up to 5.5 meters, or with an optional wheels kit, offering flexibility depending on the installation type. It also performs well under low water pressure, though a minimum of 5 bars is recommended for best results.

At just 9.5 kg, this machine is incredibly easy to handle, making it a great choice for solo operators looking for a simple yet robust tool that gets the job done without complexity.
