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.
