My only (non shop based) vac for 3+ years has been the ctl sys. I have a midi that sadly fell 15ft in its first year and is waiting for me to try and repair/salvage it. .
The ctl sys does the job fine but the long life bag needs emptying up to 4 times a day. . At the end of each job I put in a std filter bag and hoover out the longlife bag.
