I don't think it's a case of old technology. Look at Dyson - the technology used is fantastic and the cyclone works incredibly well. It's only due to Dysons popularity (which lets face it, has nothing to do with vacuuming and everything to do with clever marketing) that so many manufactures followed suit with bagless cleaners. Sadly, due to patents, they had to be cheap low efficiency cyclones. More and more companies are now developing "no loss of suction" bagless units - Vax, Hoover, Electrolux and Morphy Richards. The popularity of bagless vacuums is purely as a result of Dysons popularity which is a result of clever marketing. News flash for you Mr. Dyson - Numatic are still the best selling vacuums in the UK. Says a lot.
