Abstract
This invention relates to a hand-held vacuum cleaner (10). The vacuum cleaner is expected to have particular utility for cleaning locations which are difficult to reach with a conventional vacuum cleaner. The vacuum cleaner (10) has a body (12) with a substantially planar base (22) upon which the vacuum cleaner can rest when not in use, the body having a carrying handle (20), a motor (14) and an impeller (16) located within the body, the vacuum cleaner also having a collector (26, 126) and a battery pack (18), the battery pack providing at least a part of the base (22). The motor and the battery pack are located between the base and the collector so as to lower the center of gravity and make the vacuum cleaner more comfortable for use, especially over long periods. Ideally, the center of gravity is close to the carrying handle, and between the carrying handle and the nozzle so that the vacuum cleaner is slightly “nose heavy”.
