ABSTRACT:
Example embodiments of the invention include a cleaning system having both daily cleaning tasks and periodic cleaning tasks for cleaning and dusting a room. By utilizing less inventory and more biocompatible, “bio-safe” products than traditional systems, embodiments of the cleaning system requires less tools yet, allows its users to combine cleaning processes in a time-saving feature. The invention further includes the use of an inventive cleaning brush apparatus for which allows dirt and dust to be swept into gaps between rows of bristles, which are attached to a handle via metal rails. Accordingly, dust is concurrently collected into a row of suction holes without requiring separate steps to sweep and collect the dust. As such, the spacing of the inner and outer bristles allows for dust to be trapped in the gaps rather than permanently dispersing into the breathing air.
