Abstract:

A full power portable vacuum cleaner having a charging base which may provide vacuuming function similar to a household dustpan may employ a concealed hose and a retractable cord. To meet various cleaning demands, the vacuum cleaner may operate with different function modes, including the dustpan mode (vacuum through a port at the bottom of the vacuum body) for planar surface vacuuming, and the cordless portable mode for on-spot vacuuming. The vacuum cleaner may further employ multiple power supplies, including an internal battery supply, wall power supply, or car power supply.
