KBE5S’ state of the art combustion chamber enables virtually 100% fuel to energy conversion. This translates to clean, odorless, smokeless operation and, more importantly, fuel savings. Impervious to nature’s elements (wind, rain, and snow), the KBE5S is able to transfer infrared heat directly to the object without any loss of heat or air movement. Safety features include a tip over sensor and an overvoltage detector. Now that your workspace is warm, keep it clean with the Karcher S 650 Sweeper. It sweeps five times faster than with a broom and is easy on your back. Included with the Clean & Warm kit only from Cougar.
