  • the scrubbing member includes a plurality of scrubbing elements.
  • the scrubbing elements may define a plurality of bristles and the bristles taken together may define a scrubbing element having frusto-conical shape.
  • the scrubbing elements may be made from a material specifically designed for scrubbing pool surfaces.
  • the scrubbing member is easily detached from and re-attachable to the housing.
  • the brush is easily detached from the wheels and easily re-attached to the housing.
  • the scrubbing members are stationary.
  • the PCV may include a second scrubbing member mounted on the bottom of the housing, the second scrubbing member rotates and directs wafter flow toward the intakes.
  • the PCV may include a third scrubbing member mounted on the bottom of the housing, spaced apart from the second scrubbing member, the third srubbing member rotates and directs water flow toward the intakes.
  • the second and the third scrubbing members may rotate cooperatively, creating a current flow which directs water toward the intakes.
  • Fig. 1 there is shown an exemplary embodiment of the submersible pool cleaning vehicle (PCV) having the cleaning structure in accordance with this invention generally denoted by the numeral 20.
  • PCV submersible pool cleaning vehicle
  • the PCV 20 includes a housing 22 having an exterior 24 and an interior (not shown). Within the interior of the housing is a motor for creating a vacuum effect.
  • the housing 22 includes a conduit terminating at intakes for drawing water into a filter system and an outlet (not shown) for expelling filtered water back into the pool.
  • Such features are well known and are described in the art.
  • US Patent 7,867,389 B2 and US Application 12/100,414 show further details of the above functions.
  • the PCV 20 includes a chassis (not shown) generally within the interior of the housing 22.
  • the PCV 20 includes an electrical motor (not shown) which powers drive wheels 30.
  • the PCV 20 includes an additional free-spinning wheel 32.
  • the free-spinning wheel 32 is also mounted on the chassis.
  • the PCV 20 also includes a cleaning member 40.
  • the cleaning member 40 is mounted on an axle between drive wheels 30 as shown clearly in Fig. 1 .
  • the drive wheels 30 are positioned at the rear of the PCV 20 and a brush roller 42 defining a cleaning member 40 is positioned between the drive wheels 30.
  • the drive wheels 30 turn the brush roller 42 with sufficient torque to cause the brush roller 42 to dislodge particles and dirt and debris.
  • the brush roller 42 can be easily removed and replaced as needed.
  • a series of intakes 50 are located in close proximity to the roller 42 for sucking up such loosened matter. Again, this is well understood in the art and the references specifically incorporated above and below provide sufficient basis for understanding these principles.
  • the PCV 20, in accordance with this invention, includes a first scrubbing member 60, which comprises two sets of scrubbers as shown. Each set of scrubbers are located proximate the brush roller 42 and the intakes 50.
  • the PCV 20 includes second and third scrubbing members, 62 and 64, respectively. Each of these scrubbing members is mounted on a housing support 66, as best seen in Figs. 2 & 4 . Scrubbing members 62 and 64 include a plurality of scrubbing elements 68. The scrubbing elements 68 are attached to a rotating platform 70 as best seen in Fig. 5 . The platform 70 is mounted on the housing support 66.
  • the PCV 20 also includes a free-spinning wheel 32 positioned between the scrubbing members 62 and 64. Additionally, the PCV 20 has another intake 74, located in the bottom of the housing 22 and proximate the free-spinning wheel 32, and the scrubbing members 62 and 64.
  • FIG. 2 & 3 there is shown a bottom illustration of the PCV 20 with the PCV 20 in the upside down position. In this view, the cleaning member 40 is clearly seen between the two drive wheels 30.
  • the cleaning member 40 in the preferred embodiment in accordance with the invention is a rotating brush roller 42, attached to an axle (not shown) between the drive wheels 30. As the drive wheels 30 move the PCV 20 along the pool surface, they rotate the brush roller 42 so that it dislodges dirt and debris.
  • the brush roller 42 defines a series of peaks and valleys.
  • the brush roller 42 is made from a material that is specifically designed for dislodging such particles. Additionally, the brush roller 42 is made from an engineering plastic that is both flexible and durable for accomplishing this function.
  • the scrubbing members 62 and 64 each include a plurality of scrubbing elements 68.
  • the elements 68 are composed of a series of individual bristles 80.
  • the individual bristles 80 are grouped together and define a particular shape, namely a frustoconical shape. This shape has been found to maximize the amount of dirt and stain that can be removed by the rotating scrubbing members 62 and 64.
  • the drive wheels 30 include scrubbing elements 82 mounted over the drive wheels 30.
  • the scrubbing elements 82 define tracks having a pattern of ridges and valleys. As with the cleaning member 40, the pattern of the scrubbing elements 82 is formed to maximize the amount of dirt and stain that is removed from the pool surface contacted by the PCV 20. Likewise, the scrubbing elements 82 are made from a material suitable to perform the functions herein described.
  • FIGs. 4 and 5 there is illustrated the flow of the water after dirt and debris have been dislodged by the scrubbing members 62 and 64.
  • the rotating action of the scrubbing members 62 and 64 in the direction of arrows 90 and 92 causes a current to be created.
  • the current created flows, generally, in the direction of arrows 94.
  • the direction of flow takes the dislodged dirt and debris into the path of the intakes 50.
  • a vacuum motor (not shown) is activated within the housing 22 and a vacuum is created at the intakes 50.
  • the dislodged dirt and debris is sucked up through the intakes 50 and removed from the pool surface and the pool water. In this manner the pool is not merely cleaned but sanitized.
  • the scrubbing members are made from elastomer.
  • the degree of hardness of the elastomer depends upon the pool surface. On some pool surfaces a harder degree of elastomer is more desirable than on others.
  • the scrubbing elements are similarly customizable.
  • a wheel cover may have one type of hardness and the scrubbing element can be imbedded with a specific material that would be best suited for that surface.
  • a variety of wheel covers and scrubbing elements can be offered to the user to best suit the needs of a particular pool surface.
  • the tread on the drive wheels 30 is made from an elastomer.
  • the tread on the drive wheels is made from various compounds, both natural and synthetic to satisfy the requirements of moving the PCV and cleaning the underwater pool surface.
  • the scrubbing elements in an exemplary embodiment have a circular cross section.
  • the surface is made from a material designed to dislodge dirt and remove stain from a pool surface as the PCV collides with the surface during normal operation.
  • the material for the surface is normally hard, for example an engineering plastic.
  • the scrubbing elements include an inner core which is sponge-like and flexible in nature. Additionally, the surfaces of the scrubbing elements are designed to have a rough, but non-abrasive surface suitable for dislodging dirt, debris and removing stains from the pool surface.
