  • Surface treatment appliances such as cleaning appliance which include reciprocating cleaning heads, are used to clean and treat floors and other surfaces in the home, office, and so on.
  • Surface cleaning appliances with rotating and oscillating pads are also commonly used to clean low knap loop carpet in office environments, however the rotating and oscillating pads used with these appliances are built of moisture and dirt absorbing materials such as wool and/or polyester microfiber that must be cleaned at regular intervals for proper cleaning to be achieved.
  • Applicant has recognized that a cleaning pad that absorbs little to no moisture and dirt is effective in cleaning carpets.
  • Applicant has further recognized that various advantages may be realized by providing a cleaning pad with absorbent and/or scrubbing sections, including cleaning pads with one or more mini-shag material sections in combination with other material sections, including lower friction, glide sections.
  • a cleaning pad arrangement includes first and second pads, each with a surface-facing side configured to clean a surface, the pads being connected by one or more connectors.
  • a first surface-facing side includes one or more absorbent sections and one or more scrubbing section and a second surface-facing side includes one or more absorbent sections and one or more scrubbing sections. The presence of scrubbing and absorbent sections on the surface-facing sides allows a user to clean a surface with both sections at the same time. Thus, a user does not necessarily have to switch pads or adjust the appliance to clean different surfaces or to effectuate different types of cleaning.
  • the first and second surface-facing sides each include one or more glide portions, such as glide strips, which facilitate movement of the appliance on the carpet. By limiting friction with the carpet or other surface, the glide strips not only ease movement of the pads, they also may reduce the likelihood that leading edges of the first and second pad will separate from the appliance while cleaning.

  • a pad includes one section with a shag material and two sections with scrubbing material.
  • the absorbency of the scrubbing material is less than the absorbency of the shag material.
  • the scrubbing material includes olefin loops.
  • the pad includes one or more glide strips to reduce friction while cleaning a carpet.
  • the absorbent section is positioned in the middle of the pad with scrubbing sections adjacent to the absorbent section and glide strips adjacent to the scrubbing section in some embodiments. This configuration provides agitation for penetration of a cleaning solution into the carpet while allowing for ease of movement of the appliance across the floor while cleaning.
  • the placement of the scrubbing sections adjacent to the absorbent sections allows the scrubbing section to lift up any stuck soils and heavier dirt while allowing the absorbent section to pick up any lose debris and/or liquid.
  • the shag section, the scrubbing sections and the glide strips are positioned such that they are perpendicular an edge of a longer side of the pad.
  • the absorbent section, the scrubbing sections, and the glide strips are all positioned parallel to an edge of a shorter side of the pad.
