Abstract: This specification discloses a central vacuum cleaning system for use in a motor vehicle, which is self-contained and portable and is installed in a convenient part of the car such as the trunk. The unit is powered by the battery of the vehicle and does not require access to public power facilities. The cleaning unit is installed for easy placement and removable in the vehicle, with snap-in hose connections for convenience. The vacuum cleaner central unit is formed in two parts which are easily opened by a snap means for emptying the waste collection chamber. The waste collection chamber is designed such that debris and liquid waste remain in the bottom of the chamber during operation and during the emptying procedures, so that such wastes do not reach the filter and the electric motor area of the unit.
