Abstract
A vacuum cleaner having a base unit, a body unit pivotally mounted to the base unit, a suction generating device, and first and second dirt separation members. The first dirt separation chamber includes an inlet to receive airflow from the base unit, an outlet, a filter between the inlet and outlet, and a collection chamber having a bottom disposed below the first filter and a sidewall extending upwards from the bottom. The filter has a surface extending in a first direction, and the surface is adapted to pass the airflow radially therethrough. The second dirt separation member includes a cyclone body, an inlet to receive airflow from the first chamber outlet, and an outlet to convey airflow to the suction generating device. This outlet includes a cyclone outlet tube located within and at a first end of the cyclone body and extending in a second direction. A dirt outlet is located opposite the first end of the cyclone body. Another collection chamber is connected to the dirt outlet. The collection chambers are laterally disposed relative to one another.
