Flat cleaning brush cover plate transmission case by synchronous belt transmission, and by a single motor drive cleaning roller clear the cover plate on the brush roller flower; Ⅴ。 Flat heel and toe surface clean dish brush by two small motor drive alone. System functions are done by two motors. Compared with other advanced, high failure rate. ( Panel with carbon steel and stainless steel) The third generation: the round rod bearing transmission. Stable and has no pollution, no noise, don't have to go, after rising elevation automatically, accord with human principles. System functions performed by a motor. Low failure rate.
