Abstract
The Vacuum Cleaner is designed with a unique shape which allows it to be placed in a stable position on a flight of stairs and which overcomes the problem of instability when positioned on stairs but also remains suitable for use on a flat surface such as a floor. This shape also enables easy upward movement on stairs and overcomes the problem of manoeuvrability. The Vacuum Cleaner has one or more rotating ground engaging members which can be locked to allow rotation in a forward direction only, which overcomes the problem that previous Vacuum Cleaners have of being insecure when positioned on stairs and it may have one or more rotating members which can engage with a stair riser to allow traversing in an upward direction with very little hindrance.
