ABSTRACT:
Suction cleaning apparatus such as a road cleaning machine comprises a closed chamber for receiving dust and similar matter together with liquid such as water intermingled therewith, the chamber having a suction duct thereto for taking up dust and similar matter from a road or like surface due to suction in the duct created by suction means such as a centrifugal fan communicating with the duct and chamber, return flow means or pipework being provided for passing water from the chamber to the suction duct for intermingling with dust or similar matter drawn into the duct. On discharge of the water laden with dust and similar matter from the duct into the chamber the laden water separates by reduction in velocity from the suction air flow while the water draining from dust and similar matter deposited in the chamber is re-circulated by the return flow means to the suction duct.
