I sold most of my collection in the 90's including some pretty rare machines, but I still have a lot of them on video which can be seen on my YouTube channel. I sold these through local papers, long before Ebay existed and if I had them now, I know I would have made quite a lot of money selling them to collectors. I do regret getting rid of some models, but once I started selling them and seeing the space that was created, it got kind of addicted to it and ended up getting rid of models I wasn't originally going to part with.
I seldom got my entire collection out to look at and when I did I was sick of the sight of them after a couple of days and had to pack them away. If I had kept every cleaner I had, then I would have over 400 machines which I certainly wouldn't have room for. My collection has built up a bit over the past few years, but I do sell some from time to time and I will start selling some of the newer vacs I have bought very soon. I like buying new cleaners, unboxing them, videoing them and trying them out for the first time, but now if a cleaner doesn't suit me for any reason, I sell it. For example today I was using my Morphy Richards Lift Away, (based on the Shark Navigator Lift Away) and found it much more pleasant to use than the Dyson DC25 I bought a few weeks ago. So the Dyson is going to be sold and I will continue to use the Morphy Richards from time to time.
I really wish I didn't have this urge to buy vacuum cleaners and if I could get therapy on the NHS that would help me to stop, I would do it in a heartbeat. I do enjoy vacuum cleaners and vacuuming with different models, but when it comes down to it, they are just inanimate objects that perform a household task. This is how the majority of people see them. We are all going to die one day and our vacuum cleaners will not be waiting for us in the afterlife (if you believe there is one) and someone will have to deal with your collection after you've gone. My partner jokingly (I think) says he will hire a big skip.
Chris, I don't know how many cleaners you have, but why not get rid of a few that you like the least and see how you feel? Try and trim your collection to cleaners that you enjoy using or have for sentimental reasons.
If your collection gets you down, what is the point in keeping it?
Like I said, I regret getting rid of some cleaners, but I regret other things in my life that are more important than selling some vacuum cleaners. I lost my beautiful dog Rupert four months ago at the age of four due to diabetes and I would gladly get rid of all my collection if I could just hold him again for a few minutes.
