Abstract
An upright-type vacuum cleaner includes an upper body pivotally connected to a base unit so as to be pivoted during vacuuming or substantially upright in a parked position. The base unit includes a front portion with a suction opening and is equipped with a carriage that allows the vacuum cleaner to be moved across surfaces being cleaned during a vacuuming operation. The carriage includes at least one main wheel disposed in a rear portion of the base unit. An adjusting mechanism is configured to move the main wheel from a first position during vacuuming to a second position in the parked position with the distance from the main wheel to the suction opening being greater in the second position. An actuating element formed on the upper body is configured to engage with a lever linkage assembly of the adjusting mechanism as the upper body is moved to the parked position.
