Floor cleaning apparatus

Abstract

The present invention discloses a floor cleaning apparatus includes an upper body and a lower body. The upper body includes a lower housing a roller. The roller is arranged at an internal of the lower housing and is partially exposed externally. The lower housing includes a scraper for scraping foreign objects away from the roller. The roller includes a suction vent hood used sucking foreign objects via a negative pressure, and the scraper is adjacent to the suction vent hood to allow the scraped foreign objects to be sucked away by the suction vent hood directly. The roller includes a nozzle for ejecting a water for cleaning the roller. The present invention provides a cleaning apparatus with water ejection function. The roller can be cleaned through the water ejection and dirt can be sucked away by the negative pressure system, thereby achieving the proper cleaning effect with enhanced effect.
