Abstract

A cleaning apparatus for waste shafts has a cleaning head with peripheral brushes fixed to the head, a vibrator mounted on the head vibrating the head and thereby the brushes, a lower spray head below the brushes for applying a cleaning solution, and an upper spray head above the brushes for applying an insecticide. The cleaning head is lowered down a waste shaft by a hose containing two fluid paths, each connected to a spray head, and containing electric wires connected to the vibrator. A cart containing water, soap or detergent, insecticide, and scent tanks has metering pumps delivering fluids from the tanks through a rotary fitting to the hose which is mounted on a motor driven reel to lower the head. The hose passes over a roller clamped within an opening in the shaft. The cart may contain batteries for its operation and electronic controls and recording devices.
