This is a replacement 25ft solution/vacuum combo hose for the HSC-11500A/13000A/14000A hard surface cleaners. We do not recommend using these machines with a hose length longer than 50 feet in total length. This hose uses high flow open quick couplers, and will only work with machines that can generate over 1000psi. If purchasing this as an additional hose, you will need a hose mender to connect the 2 hoses together.
