摘要：
A method of cleaning dirt and debris from surfaces using a cleaning device, such as a vacuum cleaner. The cleaning device has a handle unit which is attached to the body of the cleaning device adjacent a filter compartment. The handle unit has a handle portion that is spaced from the filter compartment to allow a user to place his or her hand through the space and grasp the handle portion and thereby carry the cleaning device using only the handle unit. The handle unit can also be detached from the body of the cleaning device, and then later re-attached, via lockable mating connecting elements.
