Definitions

  • the disclosure is related to surface cleaning devices and in particular to kits adapted to be used with surface cleaning devices to improve the performance of cylindrical cleaning machines.
  • Conventional carpet cleaning machines remove a majority of soil in the carpets by conventional dry vacuuming, but oily or sticky soil can leave the carpet dull and unattractive.
  • Conventional surface cleaning machines with cylindrical cleaning pads or brushes use liquid gravity feed or a spray solution systems to deliver the cleaning, rinsing, or other fluids to the floor surface or to the exterior surfaces of the brushes, paddles, or pads. In the case of a liquid cleaner, the brushes, paddles, or pads are used to agitate the flooring or surface material to be cleaned.
  • the problem with gravity feed and spray systems is the variability of application to the surface to be cleaned which causes dry spots, inconsistent fluid delivery, and some overflooding of fluids on the surface. As a result, the conventional gravity-feed and spray systems provide inconsistent cleaning, excess fluid usage, over or under-wetting of the surfaces to be cleaned, and additional labor for recleaning and correction.
  • a variety of cleaning techniques using surface cleaning machines are known including wet cleaning and encapsulation cleaning techniques.
  • Wet cleaning methods have a number of drawbacks. For example, wet cleaning usually takes an extra day for the solution to dry prior to a separate vacuuming step. Also, wet cleaning may leave a sticky detergent residue which can attract soil. The residue from wet cleaning is known to re-soil the carpet faster as new dirt sticks to the detergent residue causing accelerated wear and visual deterioration of the carpet.
  • encapsulation carpet cleaning is proven to result in a preferred aesthetic appearance compared to traditional carpet cleaning methods, keeping the carpet looking cleaner for longer periods of time.
  • Encapsulation cleaning involves the application of an encapsulation solution to the carpet by gravity feed or by spraying a liquid solution on the carpet.
  • the encapsulation solution is a low moisture cleaner that includes water soluble polymers that encapsulate and crystallize around soil particles to promote easy removal by Docket No: 77834. W1 vacuuming. Detergents in the encapsulation solution break the bond of the soil with the fiber along with agitation to release the soil from the carpet/fabric and the encapsulating polymers surround and hold the dirt and soil with a dry shell coating to be vacuumed out, while leaving additional soil protection on the carpet/fibers to provide extended soil resistance.
  • Encapsulation cleaning solutions may also be used to spray a pre-generated dry foam to the carpet or exterior surface of the brushes that is rubbed onto and into the carpet by brushes, paddles, or pads.
  • the gravity or spray techniques whether liquid or dry foam, only cover the fiber surface area that the droplets touch according to a random deposition or spray pattern that is affected by the volume of fluid, direction and consistency of deposition of the fluid, and the speed that the fluid is applied to areas to be cleaned.
  • the problem with spraying a pre-generated dry foam to a carpet is that the dry foam is not sufficient to break a bond between the soil and the carpet fibers, because the foams sits mainly on the top surface of the carpet and the brushes, paddles, or pad push the dry foam across the fiber surface and across the carpet face with a minimum amount of cleaning solution. Accordingly, the dry foam only makes contact with the surface of the carpet and does not adequately penetrate the fibers or the soil in the carpet in a consist manner and with enough dwell time to release the soil effectively.
  • Encapsulation cleaning provides for faster cleaning and drying times compared to wet cleaning methods. The crystallization process used in encapsulation typically leaves no soil attraction residue on the carpet fibers. In view of the foregoing, what is needed is a more consistent fluid delivery system and device that improves the effectiveness of cleaning a surface without leaving unwanted residues and without increasing the time and labor required for cleaning.
  • An embodiment of the disclosure provides a cylindrical brush configured for depositing a fluid on a surface to be cleaned as the cylindrical brush rotates.
