Abstract
A device for removing foreign matter from a water-filled pool comprising a vacuum head equipped with a conduit connectable between suction means and a chamber-defining housing, and at least one agitation member rotatably connected to the inside of said chamber in position to be rotated by fluid suctioned from said chamber into said conduit such that turbulance caused by said rotation may dislodge fine particulate material from a pool surface.
Claims12
A device for removing foreign matter from a water-filled pool, comprising:
- a vacuum head having a chamber-defining housing, and a conduit communicating with said housing, said conduit being connectable to a suction means;
- a plurality of agitator members comprising an elongated blade rotatably attached to an axial shaft and having fluid deflecting surfaces pitched with respect to said shaft axis, said agitataor members being rotatably connected to the inside of said housing in position above the pool surface to be rotated by fluid suctioned from said housing into said conduit, rotation of said agitator members causing turbulence to dislodge fine particulate matter from a pool surface,
- a partition member positioned within said housing to define inner and outer chamber portions,
- a plurality of support means supporting said partition member from said housing;
- and
- a plurality of ports in said partition member communicating suction between said inner and outer chamber portions, each said agitator member being positioned within a said port.

- a partition member positioned within said housing to define inner and outer chamber portions,
- a plurality of support means supporting said partition member from said housing,
- a plurality of ports in said partition member communicating suction between said inner and outer chamber portions, and
- means to support said partition from said housing and to allow vertical partition movement between an upper position in which said partition seals against said housing to block liquid flow from said outer chamber portion to said conduit, and a lower position in which said partition is spaced from said housing to allow liquid flow from said outer chamber portion to said conduit, said device comprising means to resiliently bias said partition in said second position and to allow said movement in response to downward pressure on said vacuum head.
