The Riccar Heavy Duty Commercial Is great for homes with Wall-to-Wall Carpet, Shag Carpet, Berber Carpet, Soft Carpet and Pet Hair. A Quality American Made Machine With a 2 Year Warranty to back it up. This Commercial Riccar Model Comes with a Dusting Brush, Crevice Tool and a Telescopic Wand to help get dust and dirt above the ground. All Tools store right on the machine so you do not have to look around for them when it comes time to clean the corners or light fixtures. The Riccar Heavy Duty has a thermal reset switch so if a piece of clothing or a cord is run over the machine will shut itself off to protect what it has picked up and itself. For those with soft carpet we have tested the Riccar Heavy Duty on the thickest of soft carpet and it pushes very easily and cleans wonderfully.
