Abstract

A handheld vacuum cleaner (), including a main body () having a handle (), a motor assembly () positioned within the main body, and a cyclonic separator assembly () removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle () having a dirty air inlet () positioned in the front of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, and a cyclonic chamber () in fluid communication with the dirty air inlet. The cyclonic chamber defines a separator axis (). The cyclonic separator assembly further includes a dirt collection region () configured to receive debris separated in the cyclonic chamber. The inlet nozzle includes an upstream height () measured perpendicular to the inlet axis and a downstream height () measured parallel to the separator axis. The downstream height is larger than the upstream height.
