Abstract
A motorized toy vehicle or Wall Racer that is capable of operating on vertical and inverted horizontal surfaces such as walls and ceilings, while being manufacturable at reasonable cost and operable on batteries having sufficient lifetime as to be enjoyable. One or more battery-powered fans draw air from around all or defined portions of the periphery of the chassis of the Wall Racer through a carefully-shaped duct, so that the air in the portion of the duct immediately adjacent the surface flows at high velocity and low pressure; the relatively greater pressure of the surrounding air urges the vehicle against the surface, allowing it to operate on vertical surfaces, such as walls, or inverted on horizontal surfaces, such as ceilings.
