Abstract:
A handheld vacuum cleaner includes a main body with a handle extending along a handle axis. The handheld vacuum cleaner also includes a motor assembly positioned within the main body. The handle axis intersects the motor assembly. The handheld vacuum cleaner also includes a dirty air inlet positioned at a front of the handheld vacuum cleaner and extending along an inlet axis. In addition, the handheld vacuum cleaner includes a cyclonic chamber in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis. The inlet axis and the separator axis intersect to form an acute angle extending between the dirty air inlet and the cyclonic chamber. The inlet axis and the handle axis intersect to form an obtuse angle extending between the dirty air inlet and the handle.
