Abstract
A contouring broom assembly is provided for following contours of a surface. The assembly includes an angling contour mechanism (600) for allowing a cylindrical side broom (140) to angle relative to horizontal and an elevating contour mechanism (610) for allowing the cylindrical side broom to rise and fall in a substantially linear fashion. The mechanisms (600 and 610) operate separately to allow for independent elevating and angling and each of the mechanisms can be operated without active user involvement, for example, responsive to pressure exerted on the cylindrical side broom by the surface due to traversing a contour. A scrubber squeegee assembly (620) formed from discrete units (622, 624 and 626) is also disclosed. The assembly (620) allows for independent selection of the materials or characteristics of each unit (622, 624 or 626).
