Made in Germany, the MECHANICAL series are commercial-grade upright vacuum cleaners that provide the utmost in reliability, durability and cleaning effectiveness! To maximize durability, these vacuums are entirely mechanical, instead of electronic. In addition, all electrical components are located in the powerhead, with none in the bag housing or handle, thereby minimizing electrical connectors and further improving reliability. This also means that the on/off switch is located on the powerhead, and the user’s foot easily operates it. Plus, the power cord is externally located, which allows instant, tool-free removal, and replacement. All this, along with simple access to most machine parts, means that maintenance is quick and easy.
