The Viper AS430C is a 17 inch electric auto scrubber that does a great job of cleaning tile, concrete and even rubber floors. A brush is included with the machine and is recommended for any uneven surface like grout lines or rubber, and a pad driver is recommended for smooth surfaces like finished vinyl composition tile (VCT) and concrete. The 17 inch head combined with the 65′ power cord gives you a large coverage area and unlimited run time. With a high productivity rate of over 12,000 ft²/hr., the Viper AS430C will clean floors 5 times faster than traditional mop and bucket systems.
