The features, warranty, and price of the Venom floor machines make them the best buy on the market. The CSA-approved Venom buffer is available in both 17″ and 20″ models. Viper buffers come complete with pad driver, a 1.5hp motor, and an all steel triple-planetary gear box. All metal construction, combined with a 3-year parts warranty and a 2-year labor warranty means it is built to last.
