Abstract
A vacuum cleaner including a dirt cup assembly including a first stage cyclonic separator operable to at least partially separate debris from an airflow, a second stage cyclonic separator downstream from the first stage cyclonic separator and operable to at least partially separate the debris from the airflow, a container having a sidewall that at least partially defines the first stage cyclonic separator, and a shroud having a lower perforated portion located within the container, and an upper portion that surrounds and receives the second stage cyclonic separator. The upper portion is located outside of the first container such that the upper portion forms an outside wall of the dirt cup above the sidewall of the container. The shroud further includes an intermediate portion between the lower portion and the upper portion, and the intermediate portion is coupled to the sidewall of the first container.
