A device for clearing accumulated debris from eave-level rainwater gutters on buildings, comprising a travelling member (3) adapted to be positioned on or in the gutter with sufficient clearance below the overhanging edge of the roof cover for placement, operation and subsequent removal of said member, a substantially rigid longitudinal handle (7) for moving said member to and fro longitudinally of the gutter, for manipulation by a person working below the gutter, for example at ground level or on a balcony intermediate the ground level and the gutter being cleared. Optionally the handle is extensible and contractible, for example telescopically, to allow for clearing gutters at different heights. The device also includes means associated with the travelling member for dislodging any debris and forwarding it to the downpipe for disposal. The dislodging means comprises a water conduit (2) terminating in a directional nozzle (4) mounted on the travelling member, and means for supplying water to said conduit at high pressure to produce a jet effective to dislodge the debris; optionally the dislodging means is complemented by a sweeping block mounted on the travelling member to occupy a cross-sectional region of the gutter upstream of the jet for sweeping the dislodged debris in one direction of travel of the travelling member; optional a powered pump (5) is used to produce water at high pressure and optionally a closed circuit television unit is used to monitor progress in clearance. |
