In this video, I compare and review my existing Qooltek snow foam lance with Autoglym’s Polar Blaster snow foam cannon. At the time of purchasing, the Qooltek snow foam gun was the cheapest on Amazon at £18.99. Both products are compatible with Karcher pressure washers which is what I’m using to conduct this test (Karcher K4), along with Bilt Hamber Touch-Less as the snow foam product.
To ensure this is a fair test; I calculate the Panel Impact Ratio (PIR) for each snow foam lance. I also compared the differences in design, useful features and which snow foam cannon produces the best foam.
