I purchased mine back in â€™04 and felt it was well worth it. I figure we probably save money considering how many bags we would have gone through normally with a larger number of animals. I did have a few problems the first year with it occasionally making a horrible grinding noise, but was very impressed with their customer service department. A live person answered the phone and spent a long time on the phone talking me through how to fix the problem. I have not had any problems with it since then, nor has my sister that has the regular model.
The one thing I wish I would have done differently is actually compare the different models before purchasing mine- the only difference was in the attachments and the crappy cleaning solution that was included at the time(that stained my carpet
). I was not that impressed with the extra attachments though and would have been better off just getting the regular model.
