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.
