The Gumwand contains a small LPG canister, a built in reservoir for the cleaning solution, a rechargeable battery and our clever little pump. The battery powers the pump, which injects the cleaning fluid into the vaporizer at a rate around 3ml per second. The LPG powers the heating unit built into this lightweight machine. The whole unit is easily maneuvered on its wheels meaning no strain on the operator’s arm or a requirement to carry anything. NB. A nylon brush is also available for indoor use on carpets and tiles (perfect for pubs, clubs, cinemas, theatres, casinos, schools and colleges). The Proprietary Gumwand cleaning solution is derived from totally natural and sustainable sources and is ph neutral. It instantly turns discarded gum into powder, which leaves no residues.
