[WATCH IT ON BEHANCE FOR THE ENGLISH VERSION https://www.behance.net/gallery/4424943/External-Cyclonic-Filter-for-Vacuum-Cleaner ] I started this project during the 2010, and I ended it on December 2010 for my Master Degree thesis in Industrial Design. My first idea was to develop a "new" vacuum cleaner. I started the market research, benchmarking all the vacuum cleaners on the market... and what I see was that there were over 20 producers, every producers uses different technology, and for any technology at least one vacuum was on the market... I stopped to think on it, and what I tell to myself was: there is something I can do? After a while thinking on it, the answer i give to myself was: yes! In a period of economic crisis, and with an eye on planet sustainability, my idea was to make not a vacuum cleaner, but a technologic upgrade, for most of the vacuum cleaner on the market. Just like you change the CPU, or add some RAM to your PC, I decided to use the existing motor of the vacuum, to make it works better.
