I have used foam cannons with powerwasher also have foam gun with garden hose nothing comes close to this you can realy control the mixture you want and buy adding different air pressure can control the force of the stream inside door jams so it's not all over seats the different typ of foam is a plus also the large amount . Well made and the long wand helps to out product were you want it . I fill this up with optimum soap and air and take it to the coin wash inthe winter works great . Very happy with this product
