INTRODUCING THE NEXT GENERATION FLEXIBLE SHAFT MACHINE
Flexi-Rooter ®
General has rethought high-speed, exible shaft machines. The stronger, stiffer shaft lets you clean a wider range of drain lines, up to 75 feet long. It’s exible enough to negotiate 2" lines yet tough enough to clear roots in 4" lines.
General’s unique ClogChopper ® cutter in combination with the carbide tipped chain cutter makes a formidable combination, capable of clearing the toughest stoppage.
The built-in variable speed motor with foot pedal control makes the machine easier to operate. And the shaft is eld repairable. It’s everything a exible shaft machine should be.
