This is 2-in-1, as you can use it as a traditional high pressure undercarriage cleaner, as well as a soap/foam application undercarriage cleaner! This is a UK first (as far as we're aware)! Foam cannon undercarriage cleaners have slowly started to appear on the market, but almost all have one common limitation - they have fixed soap nozzles, which is perfect for applying foam under your car, but without a way to properly pressure rinse it away afterwards. Therefore we've been working on this new product, with interchangeable nozzles!
