The Trio controller is easily the most popular integrated control system on the market, and is used by the vast majority of the world's floorcare machine manufacturers. Since its introduction in 2000, nearly every new ride-on auto scrubber design has used the Trio controller to provide reliable, solid state control of all vehicle functions. On most applications, no other electronic components at all are required.

The Trio HD variant uses M6 threaded bolts for all motor connectors as an alternative to the push-fit crimp system available on the Trio . This allows the use of low-cost, commonly available ring crimps and lowers the overall installation height required, as there is no need to allow for the bend radius of the cables.
