Been fault free most of last year Steve, bought new solution hose and a new vac motor, that is currently a spare as changed brushes in old motor and was fine,also have a spare pump, just in case.
Could have bought new gear, but happy with how the old stuff is performing as are my customers.
I did invest in a rather large pro pa system though around 6kw rms ,sure my neighbours would rather I spent it on machinery though
