1. A brush, comprising:
- a first drive pulley having a primary loop engaging perimeter of a first diameter and defining a first axis of rotation;
a first idler roller having a loop engaging perimeter of a second diameter smaller than said first diameter and defining a second axis of rotation, said first and second axes of rotation together defining a plane;
a second idler roller having a loop engaging perimeter of said second diameter and defining a third axis of rotation lying within said plane;
a second drive pulley having a primary loop engaging perimeter of said first diameter and defining a fourth axis of rotation lying within said plane, said second and third axes most adjacent in said plane and said first and fourth axes separated from each other by said second and third axes;
a first flaccid endless loop circumscribing and engaging said first drive pulley primary loop engaging perimeter and circumscribing and engaging said first idler roller loop engaging perimeter;
a second flaccid endless loop circumscribing and engaging said second drive pulley primary loop engaging perimeter and circumscribing and engaging said second idler roller loop engaging perimeter;
said first and second flaccid endless loops together generally defining a lemniscate;
a plurality of work-contacting segments protruding from and carried by said first and second flaccid loops; and
a mechanical drive counter-rotating said first and second drive pulleys and thereby counter-rotating said first and second flaccid endless loops.

Abstract
An infinity brush has a flaccid belt configured to define a lemniscate. A plurality of work-contacting segments protrude from and are carried by the flaccid belt. A mechanical drive rotates the flaccid belt. Various embodiments of the flaccid belt include a single lemniscate, a plurality of lemniscates, and various simulated lemniscates. In one embodiment, the infinity brush bristle includes non-cylindrical brush bristles with a longitudinal shaft having at least one diameter transition, while other bristles comprise beads of various oval, circular, and cylindrical geometries.
