ABSTRACT:
This invention introduces a new series of vacuum cleaners or a special cover for them in which the unit will have a mechanism to prevent polluted air going out via the walls of the collection bag of the commonly used vacuum cleaners to enter into the house. This method uses different methods such as burning the smaller particles and elimination of the burned gases to prevent pollution of the room air. This unit is believed to be very beneficial in preventing the problems due to the release of these small particles into the room.
