I don't know why Shop-Vacs don't come with a hose like this in the first place.  Longer hose, flexible and tough.  Tired of wrestling with those short plastic hoses?  Tired of dragging the vacuum all over the place?  Mr. Nozzle is the answer.  Fit my 10 gallon Shop-vac QSP Pro like a glove.  And the included attachments may be all you ever need.  I plan to purchase more Mr. Nozzle soon!
