Abstract: A roof cleaning apparatus comprises a cleaning head defining a fluid conduit, the fluid conduit configured to receive cleaning fluid from a cleaning fluid source flowing in a first flow direction, the conduit redirecting the fluid so as to flow in a second flow direction different to the first flow direction and thereafter to egress the cleaning head in a fluid egress direction. The change of momentum occasioned upon fluid flowing in the fluid conduit creates a resultant force on the cleaning head in a direction away from the fluid egress direction, wherein the cleaning head is configured for mounting to an elongate support pole.
