I have had used shop vacs for many years for cleaning my shop and job sites. It has always been a hassle due to the hose. It was too short, stiff, and came unhooked. I spent more time dealing with it than doing actual cleaning. NOT ANY MORE! The Mr Nozzle hose and tool kit has taken care of all of that. The hose is twice as long, very flexable and the couplings "thread" on to the hose so no more falling off. Great solution to a frustating problem. As for other reviews stating problems with the size of the couplings I did not experience that. All of the attachments I have worked well with the new hose.
