Titan's BEST central vacuum! This power unit is manufactured by HP-Products and is built to last (it has a lifetime warranty on its motor). The TCS 8575 utilizes a filtered cyclonic filtration system. Unlike central vacuum systems that rely on permanent cloth filters, the powerful performance of Titan TCS-8575 will not decrease as dirt accumulates. In addition, the TCS-8575 features an onboard inlet valve and manual on/off switch for maximum ease of use. This unit will handle house up to 9000 square feet!
