Rug and carpet cleaning apparatus
First Claim
1. In a rug and carpet cleaning apparatus having a suction source, a source of cleaning liquid and a head displaceable by a handle over a surface of a carpet or rug to be cleaned and connected with said suction source and said liquid source, said head being provided with a driving motor and a plurality of drivable units selectively engageable with said surface and adapted to be coupled with said motor for performing respective cleaning operations upon said surface, said head having a housing receiving said units, the improvement which comprises:
- a rocker disposed in said housing and comprising a pair of members extending in a direction of displacement of said head and spaced apart to form opposite members of a frame;
means for pivotally mounting said rocker in said housing on an axis transverse to said direction whereby parts of said rocker to opposite sides of said axis can be brought selectively closer to said surface upon the tilting of said rocker in opposite senses about said axis, said units being respectively mounted on said parts of said rocker for selective approach to said surface, said motor being mounted on said rocker;
means forming a continuous driving connection between said motor and one of said units on said rocker; and
means actuatable on said handle for controlling the direction of tilt of said rocker about said axis.

Abstract
A rug and carpet cleaning apparatus of the type in which a housing is shifted along the floor and is connected to a suction chamber while having rotary brush, carpet-shampoo, massager, and like rotary units which are selectively to act upon the carpet depending upon the function or operation to be carried out. According to the invention, at least two such units are provided on opposite sides of the fulcrum or pivot of a rocker or teeter which is controlled, e.g. by a lever and cable arrangement, to selectively bring one or the other unit into action depending upon the tilt imparted to the rocker. Both units can be continuously coupled to the drive motor which can also be mounted on the rocker.
