A separation system (100, fig.1) for a vacuum cleaner (10, fig.1), comprising a chamber 122 housing a filter 202 for filtering airflow entering through an airflow inlet (140, fig.6), which extends in a length direction along the chamber and has a U-shaped (i.e., C-shaped or curved) cross-section when viewed along the length direction. The filter may extend in a direction parallel to a first axis along which the airflow enters the chamber. A second filter 208, preferably of flat cross-sectional shape, may underlie the first filter such that airflow flows through it after flowing through the first filter in a direction orthogonal to the first axis. The airflow may then flow to an outlet channel (310, fig.17) underlying the filter, which extends parallel to the first axis, and into a motor assembly (1000, fig.1) before exiting the device. A valve (304, fig.17) may cover a base of the chamber, for controlling airflow through the airflow inlet. The chamber may be defined by a bin body 108 for collecting dirt, where a bin interlock member inhibits removal of the bin body from a core 300 when a cleanerhead (3000, fig.1) is attached.
