Abstract: A vacuum cleaner can include an upright section, a surface cleaning head coupled to the upright section, and at least one wheel coupled to the surface cleaning head. The at least one wheel can include a hub, a rim, and an absorber. The absorber can extend between the hub and the rim. The absorber can be configured to deform before the rim experiences substantial deformation. A deformation limiter can be provided that is configured to limit the deformation in the absorber.
