Steam cleaner

Abstract

A steam cleaner includes a main body, a water supply system, a connecting member, a support member, a connector, a dust cleaner, and a cleaning unit. Thus, the steam cleaner provides washing, cleaning, dusting and recovery effects simultaneously, thereby enhancing the versatility of the steam cleaner. In addition, the push button is locked by the locking block, so that the water supply system is operated successively, thereby facilitating the user operating the steam cleaner. In addition, the liquid is filtered by the filter before entering the heater to prevent the metallic material contained in the liquid from being attached to the heater, thereby enhancing the lifetime of the steam cleaner.
