I love this vac.   I purchased the spacking cleaner 3 to 5 years ago and it has worked great for me.  The pet hair doesn't get hung up in it and it's not until just recently that the motor has started making a high pitch sound but I mean as long as I've had it and put it through I understand.  It has the easiest filter to clean, and  I've never once had replaced the filter because it's made pretty durable.
