Abstract: A portable vacuum cleaning system includes a portable vacuum unit for cleaning debris. The vacuum unit is powered by a self-contained first battery and may be carried with a strap in backpack-fashion. The system also includes a cart defining a receptacle for receiving the vacuum unit. The vacuum unit may be used when supported by the cart or when carried by an operator. A second battery is supported by the cart and electrically connectable to the vacuum unit for charging the first battery when the vacuum unit is supported by the cart. Further, when disposed in the cart, the vacuum unit is disposed at an angle of about 45 degrees allowing for ease of movement of the cart.
