Definitions

  • Mobile floor cleaners such as those produced by Tennant Company of Minneapolis, Minnesota, are generally designated as either a soft floor cleaner configured to perform a cleaning operation on a soft floor (e.g., carpet, rugs, etc.), or a hard floor cleaner configured to perform a cleaning operation on a hard floor surface (e.g., tile, linoleum, cement, etc.).
  • a soft floor cleaner configured to perform a cleaning operation on a soft floor
  • a hard floor cleaner configured to perform a cleaning operation on a hard floor surface (e.g., tile, linoleum, cement, etc.).
  • Soft floor cleaning operations include soil transfer and deep extraction cleaning operations.
  • U.S. Patent No. 6,735,812 which is assigned to Tennant Company, describes a dual mode cleaner that is configurable to perform both soil transfer and deep cleaning extraction operations on a carpeted surface.
  • Soil transfer cleaning operations utilize special cylindrical rollers to which a cleaning solution is applied with pumps and spray heads.
  • soil is transferred to the rollers and the soil cleaning liquid is subsequently suctioned from the rollers with vacuum extractor tools.
  • This technology can be used to clean various fabric surfaces.
  • the roller design, rotational speed, pressure, vacuum parameters and cleaning liquid flows can be altered in the same machine to optimize cleaning for the particular carpet or fabric.
  • the cleaning liquid can be minimized to reduce drying time while still providing effective interim cleaning of carpet, thereby allowing a space to be ready for use in less than one hour.
  • Deep cleaning extraction cleaning operations are typically performed less frequently than the soil transfer cleaning operation.
  • the deep cleaning extraction operation generally performs a more thorough cleaning of a carpeted surface.
  • a relatively large amount of cleaning solution is sprayed directly onto the carpeted or soft floor surface.
  • the carpet is scrubbed with brushes designed for the surface and soiled liquid is extracted from the carpet with one or more vacuum extractor tools located behind the brushes.
  • Carpets cleaned with the deep cleaning extraction operation require considerably longer drying times before use than carpets cleaned with the soil transfer method.
  • Hard floor surface cleaning operations are performed by hard floor surface cleaners that generally employ scrubbing brushes and a vacuumized fluid recovery system positioned behind the scrubbing brushes.
  • a cleaning liquid is typically sprayed directly to the floor and/or on the brushes and the hard floor surface is scrubbed with the brushes.
  • the vacuumized fluid recovery system typically includes a vacuum squeegee that collects the soiled cleaning liquid and delivers the soiled cleaning liquid to a recovery tank. The vacuum squeegee removes substantially all of the liquid waste left by the scrubbing brushes from the hard floor surface, leaving the surface ready for use almost immediately.
  • the present invention generally relates to a floor cleaner configured to perform both hard and soft floor cleaning operations.
  • the cleaner generally includes a mobile body, a motorized cleaning head, a cleaning liquid dispenser, a vacuum, a first vacuum extractor tool and a vacuum squeegee connected to the mobile body.
  • the mobile body is configured to travel over a surface.
  • the motorized cleaning head is connected to the mobile body and includes a cleaning tool.
  • the cleaning liquid dispenser is configured to apply a cleaning liquid to the surface or the cleaning tool.
  • the first vacuum extractor tool is configured for vacuum communication with the vacuum through a first vacuum path.

  • the cleaning head 108 is configured for use with multiple types of cleaning tools 128 in order to accommodate different cleaning operations while using the same motors 130, for example.
  • the cleaning head 108 can be equipped with a soft floor cleaning tool 128 to allow the cleaner to perform a soft floor cleaning operation.

  • the extractor tool generally extends widthwise across the surface 178 of the cleaning tool 128 or the surface 112, from which waste 162 is to be extracted. Multiple extractor tools 114 can be used to cover large widths. It is understood by those skilled in the art that extractor tools 114 are used for removing liquid and solid debris from soft surfaces 102, such as soft floor surfaces and soft soil transfer roll surfaces, and they do not include a squeegee that would render them operable on hard floor surfaces.

  • the roll extractors 180 engage the surfaces 178 of the rolls 134 and are placed in vacuum communication with the vacuum 112, which removes some of the just deposited cleaning liquid 230 and soil previously transferred from the surface 102. As a result, the wetness of the rolls 134 is reduced from the initially sprayed condition by the extraction of some of the cleaning liquid 230 by the roll extractors 180.
  • the rolls 134 As the rolls 134 are revolved, they engage the soft floor (e.g., carpet fibers) 102 and cause soil to be transferred from the carpet fibers to the rolls 134. After engaging and wiping the surface 102, the rolls 134 are further rotated and sprayed again with cleaning liquid 230 by nozzle 260. Subsequently, the surfaces 178 of the rolls 134 are vacuum extracted to remove the soiled cleaning liquid 162 from the rolls 134, which is conveyed into the recovery tank 170.
