Abstract
A vacuum cleaner including a handle and a base. The base includes a housing, a nozzle defining an inlet of the vacuum cleaner, and a lift assembly including a guide member configured to support the base on a surface. The vacuum further includes a height adjustment mechanism including a knob and a ramp. The knob is operable to rotate the ramp with respect to the housing, and the lift assembly is coupled to the ramp such that the lift assembly moves along the ramp to move the inlet from the lower position to the upper position in response to rotation of the ramp by the knob. The ramp includes a first end that defines a lower position of the inlet and a second end that defines an upper position of the inlet, and the ramp has a continuous incline from the first end to the second end.
