Using easily interchangeable drums, the Speedrooter XL from General Pipe Cleaners clears tough clogs in 3- to 10-inch lines. It has a 3/4 hp motor and 100-foot-capacity drums for Flexicore cable. Change the drums to add cable lengths or swap cable sizes easily. Loosen three knobs and remove the drum to switch between 3/4- or 5/8-inch cables in the large drum design. With a see-through inner cage, quickly gauge how much cable remains — or substitute the small drum with 100 feet of 1/2-inch cable for smaller lines. A variable-speed cable feed offers driving and pulling power for long, tough jobs, feeding and retrieving 3/4-, 5/8- and 1/2-inch cables. Turning a knob on top of the feed adjusts 3/4- or 5/8-inch cables. 800-245-6200; www.drainbrain.com.
