The CLL-6 represented a droid model, specifically a binary loadlifter, manufactured by Cybot Galactica in the waning years of the Galactic Republic. Its fundamental processor enabled the droid to move and execute commands. Due to its literal interpretation of Basic language commands, a protocol droid was usually needed to accurately convert instructions into Binary.
As one of the earliest and most uncomplicated droid designs throughout the galaxy, CLL-6 units are recorded to have engaged in Nuna-ball leagues, alongside their primary function of lifting loads. Back in 22 BBY, the CLL-6 series team from Cybot Galactica emerged victorious with a score of 67-41 in a game against the 8D team from Roche.
