A vacuum attachment (1) for a blower (2), comprising: an input air channel (3) having an air inlet (4); and a through channel (5) from a vacuum inlet (6) to an outlet (7), in which the input air channel (3) terminates in a port (8) in the through channel (5), in which the port (8) is positioned so as to direct air flowing from the input air channel (3) in a direction through the through channel (5) away from the vacuum inlet (6), in which the air inlet (4) has a mounting surface (9) on which can be mounted an air outlet (10) of the blower (2) in a releasable and re-engagable manner. Thus, with a blower (2) connected to the air inlet (4), an airflow introduced at the air inlet (4) will cause an airflow from the vacuum inlet (6) to the outlet (7), entraining debris with the airflow.
A vacuum attachment for converting a blower into a vacuum apparatus, comprising:
A backpack mounted vacuum apparatus, comprising a source of pressurized air, an input air channel having an air inlet coupled to the source, a through channel from a vacuum inlet to an outlet, in which the input air channel terminates in one port extending around an internal circumference of the through channel, the port is positioned so as to direct air flowing from the input air channel in a direction through the through channel away from the vacuum inlet, and the port extends around at least three quarters of the circumference.
