Cyclon vacuum cleaner

Cyclon vacuum cleaners have been getting popular maybe since last year. I am not clever enough about mechanic but like new stuff, so I bought 2 cyclon vacuum cleaners as an old vacuum cleaners did not work good.
　They said cyclon vacuum cleaners swallow better than old ones, so I expected how they worked. But they need me to clean inside almost every after I use them. This is kinda tiresome!!!! (^^;;;　
　They are powerful enough to swallow dust as I always clean the inside. It's like I always use a new dust pack for an old vacuum cleaner.
I wonder if anyone could tell me how I can make it easier to clean the inside of cyclon vacuum cleaners.

Actually one of old vacuum cleaners which I bought more than 20 years ago when I began this innkeeping work still works for us! Its ability to swallow dust seems a lot less than newer ones but I feel it as powerful as newer ones. Also, I feel products made in 1980's are steady enough to use for long. Is it only I who feels products nowadays are not steady enough to use?
