Abstract
An electric cleaning device circulates exhaust air from an electric blower to a floor intake tool. The exhaust air passes through an exhaust guide, formed as one element, in a main cleaning device unit from the electric blower through a hose to the floor intake tool. The exhaust guide is a resilient unitary resin part with sufficient resilience to permit compression for installation. The springback of the exhaust guide seals the exhaust path against leakage.
