The Prochem Dual-Jet Long Stair Tool is one of the best quality, easy-to-use stair tools on the market. This tool is cast-constructed of high grade stainless steel and uses a 2" cuff (the same as most wands - so there is no need for changing " mid-stream"). This will make the hard work of stair cleaning a breeze. You'll never know how good it can be until you get one.
