This dustbuster is a replacement for the one I had for over 15 years. It is really handy to have around but I have to say, it isn't as good as the one I had previously. The suction power is limited and it is necessary to continue emptying the barrel in order for it to vacuum adequately. This one was on the lower price range and I must say, you get what you pay for. When this one wears out, I will replace it with a more powerful one. For now, it handles small jobs well. After sweeping, instead of a dustpan, I use this machine. It is very easy to clean. All parts are easily removed for cleaning. I haven't had to replace any of the parts as yet. I wash the filter but replacement filters are available.
