The 91431 is designed to be a general use straight air accessory set for the home, shop, or garage. Often it is used as a second tool set complimenting the power nozzle or turbine package that came with the central vacuum. Having a second tool set can save you time and effort moving a tool set from floor to floor in multi-story homes. The hose end is designed for what has historically been industry standard inlets and will activate a system with low voltage contacts in the wall valve. There were a few valves typically produced before 1980 which may use a micro-switch for activation of the vacuum. In most cases the 91431 will still work but the automatic activation of the system will not be delivered by the banded cuff. The set includes a full range attachments for most standard household cleaning jobs. This set is deal for a basement, garage, or general use in the home, especially on hard floor areas. The floor brush is ideal for cleaning hardwood, tile, stone and vinyl.
