The high-quality bio-chem foam cannon allows for even and rapid application on larger areas. The previously liquid cleaner transforms into a highly effective foam through the foam cannon, which adheres well even on vertical surfaces, thereby improving cleaning performance. Includes 3 foam nozzles for variable foaming. Fill the foam cannon with 500 ml of liquid, then pump about 15 times until the foam reaches the upper marking. Done. Apply foam from a distance of 50 - 70 cm.
