I've had mine for 5 1/2 years & it still works & that is good. However it always did a really poor job at cleaning.I believe it is the whole bagless technology, after doing a little research on the web. It throws out a lot of particles at your feet as you use it. When stuff isn't hitting your feet, its time to see if its clogged up somewhere. The most popular clogging point is the plastic cone filter inside and above the canister, and/or the tunnel leading to it. One also has to deal with the main filter & its foam sub filter, and the HEPA filter.The whole operation is a dirty mess, from dumping the canister contents into the trash to cleaning the filters all of the time, to walking on a dirty floot that you just vacuumed.I will never buy a bagless vac. (unless some sort of shop vac. type thing maybe).
