The invention provides a vacuum cleaner (10) having a chassis (12), supporting wheels (14) mounted on the chassis (12), drive means (15) connected to the supporting wheels (14) for driving the supporting wheels (14) and a control mechanism for controlling the drive means (15) so as to guide the vacuum cleaner (10) across a surface to be cleaned. A cleaner head (22) having a dirty air inlet (24) facing the surface to be cleaned is mounted on the chassis (12) and separating apparatus (52) is supported by the chassis (12) and communicates with the cleaner head (22) for separating dirt and dust from an airflow entering the vacuum cleaner (10) by way of the dirty air inlet (24). The separating apparatus (52) comprises at least one cyclone(54,56). This type of separating apparatus is not prone to clogging and therefore the pick-up capability of the cleaner (10) is maintained at a high standard.
A vacuum cleaner, comprising a chassis, supporting wheels mounted on the chassis, a drive connected to the supporting wheels for driving the supporting wheels, a control mechanism for controlling the drive so as to guide the vacuum cleaner across a surface to be cleaned, a cleaner head having a dirty air inlet facing the surface to be cleaned, and a separating apparatus supported by the chassis and communicating with the cleaner head for separating dirt and dust from an airflow entering the vacuum cleaner by way of the dirty air inlet, wherein the separating apparatus comprises at least one cyclone having a cyclone body with a longitudinal axis and wherein the separating apparatus is supported on the chassis with the longitudinal axis of the cyclone body lying in a substantially horizontal position.
A vacuum cleaner comprising a chassis, supporting wheels mounted on the chassis, a drive connected to the supporting wheels for driving the supporting wheels, a control mechanism for controlling the drive so as to guide the vacuum cleaner across a surface to be cleaned, a cleaner head having a dirty air inlet facing the surface to be cleaned, and a separating apparatus supported by the chassis and communicating with the cleaner head for separating dirt and dust from an airflow entering the vacuum cleaner by way of the dirty air inlet, wherein the separating apparatus comprises at least one cyclone and wherein the control mechanism is electrically shielded from electrostatic fields generated by the cyclone.
A vacuum cleaner comprising a chassis, supporting wheels mounted on the chassis, a drive connected to the supporting wheels for driving the supporting wheels, a control mechanism for controlling the drive so as to guide the vacuum cleaner across a surface to be cleaned, a cleaner head having a dirty air inlet facing the surface to be cleaned, and a separating apparatus supported by the chassis and communicating with the cleaner head for separating dirt and dust from an airflow entering the vacuum cleaner by way of the dirty air inlet, wherein the separating apparatus comprises at least one cyclone and a removable bin in which, in use, dirt and dust is collected, and wherein the removable bin is transparent or translucent.
