The professional foam gun works perfectly on Karcher K2/K3/K4/K5/K6/K7 pressure washer.
It produces a nice thick layer of foam on the car, helps clean the vehicle faster and reduces the wash time considerably.
The tank is big enough(capacity: 34 oz.) so that you can do a full spread on 4-5 sedan cars with one fill.
The spray nozzle is adjustable so you can adjust the pressure size of foam/water that comes out as you want. Plastic but solid connector is much lighter than brass connector, which brings a flexible and convenient operation.
Light color of the soap bottle makes it easy to identify the level of soap remaining. The bottle is very thick and the good sealing of the nozzle makes the foam gun never leaks.
