I have been using it for a year, its very useful in the winter time here in Ohio because of the salt residue that my mops can't get off the floors. Its going strong still, just gotta make sure you keep up on maintaining hoses and wiping it down after each use. Check the video：https://youtu.be/N7PcR7QcYto?si=QgLRgKI0-xQ_pPIA
