Abstract: A self-cleaning vacuum cleaner 1 is disclosed. The vacuum cleaner 1 comprises a housing 2 having an inlet 5 and an outlet 6, and a fan arranged within the housing 2 for causing air to flow through a coarse filter and a fine filter. A vibrator mechanism causes vibration of the fine filter, and the vacuum cleaner 1 has a working condition in which the fan causes air to flow from the inlet 5 to the outlet 6, and a self-cleaning condition in which the vibrator mechanism causes vibrations of the fine filter to cause particles to be released from the fine filter, and in which the housing 2 is opened to enable at least some of the particles released from the fine filter to pass through the coarse filter and out of the housing 2 and into a receptacle 10.

Abstract: A vacuum cleaner 2 having a housing 4 having an inlet 12 and an outlet 54 is disclosed. Actuation of a motor 46 causes a fan to displace air out of outlet 54, and the resulting suction upstream of the fan draws dirty air through inlet 12 and inwardly through walls of filter unit 22. Air from filter unit 22 passes along a duct to the motor 46 and fan. The housing 4 is formed from a first housing part defining a recess 36, and the recess is then closed by means of a closure member 56 to define the duct between the filter unit 22 and the motor 46.
