Flexible rotary brush hub

A flexible hub system arranged about a rotational axis, comprising:

• a rigid disk-shaped impeller plate having an upper side and a lower side, the impeller plate centered on the rotational axis and including a flexible portion centered on the rotational axis and comprised of a flexible material, the impeller plate further including a plurality of discharge outlets proximate to an outer edge of the impeller plate, a plurality of radial impeller vanes, each radial impeller vane extending outward from the lower side, and wherein the impeller plate is configured for coupling to a drive shaft centered on the rotational axis;
• and
• a volute centered on the rotational axis and including a central volute hole, wherein the volute is coupled to the impeller plate such that the impeller vanes are interposed between the volute and the impeller plate and the discharge outlets are located within a perimeter base of the volute, whereby upon submerging of the flexible hub system in a fluid and rotation of the flexible hub system around the rotational axis the flexible hub system is rotated and fluid is drawn into the central volute hole and is discharged out the discharge outlets, whereby suction is created.
