Abstract
A cleaning apparatus having a cleaning member movably arranged at a housing, the cleaning member having a cleaning portion for engaging a surface to be cleaned; a handle member connects with and is resiliently movable between a raised position and a lower position so that when the handle member is arranged at the raised position, a resilient member operably connecting the handle member with the housing is substantially compressed thereby applying a pressing force onto the cleaning member towards the surface to be cleaned.
Claims17
A cleaning apparatus, comprising:
- a cleaning member movably arranged at a housing, the cleaning member comprising a cleaning portion for engaging a surface to be cleaned;
- a handle member arranged to connect with the housing and is resiliently movable between a raised position and a lower position relative to the housing;
- a positioning member for supporting and positioning the cleaning member on the surface to be cleaned, the positioning member comprises at least one plate member being substantially planar and extending substantially horizontally from the housing;
- wherein, in operation, the handle member is movable between the lower position and the raised position between an angle of about 0 degrees to about 90 degrees in respect of a horizontal plane of the surface to be cleaned, and when the handle member is arranged at the raised position, a resilient member operably connecting the handle member with the housing is substantially compressed at an angle to the horizontal plane of the surface to be cleaned, such that angular compression of the resilient member generates a downward component force perpendicular to the surface to be cleaned thereby causing a downward pressing force onto the positioning member for positioning the cleaning member towards the surface to be cleaned.
