This is a 25ft solution/vacuum combo hose for the XPC-12000 cold water machine and XPH-12000H hot water machine to allow you to use a carpet or upholstery wand with your machine. These machines came with either a gray or black hose. We do not recommend using these machines with a hose length longer than 50 feet in total length. If purchasing this as an additional hose, you will need a hose mender to connect the 2 hoses together.
