Abstract
A surface cleaner including a housing and a blade assembly with a blade element. The blade assembly is movable between a lowered position and a raised position relative to the housing. A spring is coupled between the housing and the blade assembly, and the spring applies a force on the blade assembly to move the blade assembly toward the lowered position. The blade element is allowed to move toward the raised position, against the force, such that the force maintains the blade element in contact with a surface to be cleaned. In addition, when in the raised position, the blade element is held against the force and inhibited from moving toward the lowered position.
