ABSTRACT:
The disclosure concerns a shoe attachment for insertion in the intake orifice of an electric vacuum cleaner that includes a housing having an intake orifice at the underside thereof. Wheels support the housing and raise the intake orifice off the surface to be cleaned. The shoe attachment is detachably fitted in the intake orifice. The shoe attachment has an undersurface that rides along the surface to be vacuum cleaned. A narrowed width inlet opening through the shoe attachment increases the intake air speed and/or the suction force, facilitating picking up of heavy material and liquid. The shoe attachment is flexible and resilient to conform to irregularities in the surface being vacuum cleaned.
