Abstract
A self-propelled vacuum cleaner adapted to be used in an upright mode or, alternatively, in a portable mode. The vacuum cleaner includes a power transmission for self-propelling the vacuum cleaner when used in the upright mode. The vacuum includes a first handle usable during operation in the upright mode and control structure arranged to energize the transmission in response to manually applied pulling or pushing forces on the first handle. The vacuum cleaner further includes a second handle usable during operation in the portable mode and arranged to prevent the control structure from energizing the transmission during operation in the portable mode.
