Abstract

A handheld vacuum cleaner that includes a fluid flow motor is positioned in a main body along a fluid flow path and defines a motor axis. A premotor filter is disposed in the main body and includes an annular filter media forming a filter axis. The annular filter media includes a first end, a second end, and a longitudinal filter surface extending between the first end and second end. The annular filter media surrounds a filter air passageway along the filter axis and upstream of the fluid flow motor. A debris separator is upstream of the premotor filter in the fluid flow path and defines a debris separator axis. The filter axis is generally parallel to the motor axis.
