Nilfisk Alto (Kew) Bayonet Connection Super Foam Sprayer comes with a 1 litre detergent bottle. It produces a rich foam which stays on the surface for longer, reducing the need to re-foam. The dose of foam and detergent can be regulated, as it is easy to access the inbuilt filter, making it easy to remove any blockages. The sprayer can be connected to the gun handle of any Nilfisk Consumer pressure washer, but is designed for use with the Premium Pressure Washer spray lance.
