Hand cart

A scrubber is disclosed including an applicator for applying a cleaning solution, a rotary brush for working such solution on the soiled surface and a pick up section for removing the cleaning solution and suspended soilage from the surface being scrubbed. The scrubber includes a dirty solution chamber and a clean solution chamber. A separator is provided between such chambers to separate the dirty water into a sludge portion which is returned to the dirty water chamber and a clean solution portion which is fed into the second chamber.

Scrubbing machine with water regeneration

A scarifying tool is disclosed suitable for use in conjunction with disc floor maintenance machines. The scarifying tool includes a support plate with a plurality of resilient or flexible members attached thereto. The flexible member may be lightweight spring-steel strap material one end of which is secured to a disc plate. A cutter is then mounted on the strap at a point spaced from the disc support.

Scarifying machine

A method for cleaning surfaces such as floors and pavements that includes incorporating a polyelectrolyte in the cleaning solution and a surface scrubbing machine for carrying out the process. As specifically disclosed, the method comprises applying the cleaning solution to the surface together with agitating the solution on the surface to cause formation of flocs, removing the floc containing solution from the surface by, for example, squeegeeing, and returning the recovered solution to a solution tank and, if desired, separating out the flocs. With a scrubbing machine the solution tank is on the machine, and the agitation may be provided by, for example, a rotary brush on the machine, or by applying the cleaning solution to the surface by forcing the solution under pressure through discharge nozzles. Although not necessary for some cleaning operations, in others a detergent or soap compatible with the polyelectrolyte is incorporated in the solution. With various combinations of polyelectrolyte and detergent, the addition of a suitable flocculation aid such as metallic salts to the solution enhances the degree of flocculation and the strength and size of the flocs.

Surface cleaning method and machine

A detergent composition particularly useful in aqueous solutions for cleaning soiled surfaces. The formulation which may be in either dry or concentrate form, includes alkaline builders, wetting agents, and a flocculant, and may in certain instances, include a floatation agent. As an alkaline builder, sodium tripolyphosphate is normally preferred, while others such as mixtures of sodium tripolyphosphate with sodium sulphate or potassium hydroxide and soda ash may also be successfully utilized. The formulation is preferably applied to the surface as an aqueous solution in relatively heavy or thick layers, with agitation to permit the removed soilage to create flocs, and with the flocculated soilage being floated away from contact with the surface for facilitating removal.
