Abstract
An upright surface treating appliance includes a main body having a user operable handle, and a support assembly for allowing the appliance to be rolled along a surface using the handle. The support assembly includes a yoke and a pair of wheels rotatably connected to the yoke, the yoke being shaped so that a section of the yoke lies between the rims of the wheels. A surface treating head is connected to the yoke. The main body is pivotably connected to the yoke for movement about a pivot axis passing between the wheels, and so that a part of the main body is located between the rims of the wheels. As the main body is pivoted about said axis from an upright position to a reclined position, the spacing between said section of the yoke and said part of the main body increases, and so a shield is provided for covering the gap so formed between said section of the yoke and said part of the main body to prevent dirt and dust from passing into the support assembly through the gap.
