What cleans the tile & grout so fast and effectively without the use of excessive water and harsh chemicals? The engineering behind the ORBOT, brush, and weight kit. The ORBOT generates thousands of miniature orbits that scrub together with the brush. Imagine a giant orbiting toothbrush that is soft enough that it will not scratch the floors yet is effective enough to scrub away grease and grime from the pores and crevices found in ceramic tile and grout. Together adding the weight kit with the brush and orbital action of the ORBOT, the bristles are pushed down into these pores and crevices lifting away immediately the dirt and grime.
