Vacuum cleaner
First Claim
1. An autonomous vacuum cleaner, comprising a body having supporting wheels, drive means for driving the wheels so as to propel the vacuum cleaner in a direction across a surface to be cleaned, dust and dirt separating apparatus, a fan for drawing air into the dust and dirt separating apparatus and a cleaner head mounted beneath the body, transversely to said direction, and incorporating a dirty air inlet facing the surface to be cleaned,wherein the cleaner head protrudes transversely beyond the body on a side of the vacuum cleaner and wherein the wheels are mounted on the sides of the body and the cleaner head extends beyond the wheels on the side.

Abstract
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.
