A mounting assembly 100 for mounting a roller brush 12 onto a cleaning apparatus includes a mounting flange 102 and an end cap 104 interconnected together by extension springs 176 spanning therebetween. An idle shaft 106 is slidably mounted in the mounting flange 102 by a bearing interface 108. The distal end of the idle shaft 106 is fixed to the end cap 104 so that the springs 176 that urge the end cap 104 into engagement with the mounting flange 102 also bias the idle shaft to extend forwardly of the mounting flange while also permitting the idle shaft to retract to facilitate assembly and disassembly of the roller brush with the mounting assembly 100. The bearing interface 108 is designed to permit the projecting proximal end of the idle shaft to tilt upwardly to facilitate engagement with and disengagement from the roller brush 12.
