Abstract
A cleaner for carpets, rugs and the like has a roller or brush or the like by means of which cleaning foam is to be applied to the particular textile. It is further provided with two or more chambers, each adapted to contain a chemical component. The chemical components in the several chambers are of the type which, upon contact with one another, will spontaneously react and produce foam for cleaning purposes. An arrangement is provided for permitting the controlled contacting of these components with one another so as to produce the requisite foam which is supplied to the roller or brush.
Claims12
An apparatus for producing foam for cleaning of textiles, especially of rugs and carpets, comprising applying means for applying foam to a surface to be cleaned;
- wall means defining two chambers each of which is adapted to accommodate one of two chemical components which react upon contact with one another and spontaneously produce foam for cleaning purposes;
- first and second passage means connecting said chambers with one another and with said applying means;
- and control means for selectively varying the effective cross-section of said first passage means so as to permit contacting of controlled amounts of one of said components with the other component via said first passage means, to result in spontaneous production of foam which is supplied to said applying means.
