The rotatable wheel (100) includes a central axis (101), a wheel portion (102), a hub portion (110) including an offset axle aperture (112) that receives a rotatable component, and one or more detent devices (111). The retainer device (200) is retained in a chassis of the vacuum cleaner and includes a body (201), a hub portion aperture (202) formed in the body and of a size to rotatably receive the hub portion of the rotatable wheel, and one or more biasing devices (204) that interact with the one or more detent devices in order to provide a plurality of predetermined detent positions. The rotatable component is moved substantially vertically with respect to the central axis when the rotatable wheel is rotated between the plurality of predetermined detent positions.
