Abstract

A hand vacuum cleaner includes a housing having an inlet and an outlet, and a front and a rear part connectable with each other so as to constitute the housing. The housing has a front face and a rear face spaced from the inlet in the flow direction of incoming contaminated air entering the housing. A dust filter is located in the housing at the rear face thereof. A blower is located in the housing for aspirating the contaminated air into the housing through the inlet and into the dust filter and for urging the filtered air therefrom in a second direction towards the outlet. An intermediate plate is provided in the interior of the housing, which has a first formation constituting a first passage for the incoming contaminated air, a second formation constituting a second passage for guiding the filtered air from the dust filter towards the outlet and a third formation for fixing thereon the blower.
