A vacuum cleaner comprising a cyclonic separating apparatus including a dirty air inlet, a main body connected to the cyclonic separating apparatus and a motor and fan unit for generating an airflow through the cyclonic separating apparatus from the dirty air inlet to a clean air outlet, wherein the cyclonic separating apparatus includes at least a first cyclonic cleaning stage and an elongate filter arranged fluidly downstream from the first cyclonic cleaning stage, the elongate filter being housed in a duct at least partially surrounded by the first cleaning stage, and wherein the filter comprises an inlet portion and a filter portion defining a generally tubular filter chamber, the inlet portion including one or more radially facing inlets to permit air to flow into the inlet portion in a radial direction from where the air flows from the inlet portion to the filter chamber in an axial direction.
A removable filter for a vacuum cleaner, the removable filter comprising a tubular inlet portion carrying a tubular filter media portion defining an interior chamber having an axis, the inlet portion including one or more radially facing inlets for receiving air flow into the removable filter such that a radial air path is defined for air to flow into the inlet portion and an axial air flow path is defined for air to flow from the inlet portion to the interior chamber, wherein during use, air flows from the interior chamber radially outwardly through the tubular filter media portion.
