Same problem here. It's clear from a quick web search that it is a very common problem with this vac. I just spoke to the customer service department and the rep basically implied that it was my fault for not having cleaned the filter earlier. I explained to her that although the vac was purchased some time ago, it has only been used for a couple of months. We had a housekeeper who comes to clean our house and brings her own vac. The customer service representative chastised me to clean the filters more often- said that she would send me a free new filter just this once. What a catch 22. I obviously will not clean the filters more often since apparently everyone who owns this machine has a problem with the filter after they clean it. But if I have a problem with my machine in the future, they'll tell me the warranty doesn't cover it since I haven't cleaned my filters. Also the filters are impossible to clean. The owner's manual says to let them dry for 24 hours before replacing in vacuum, but not to replace unless they are totally dry. I let my filters dry for 72 hours and they were still damp. I finally had to dry them with a hair drier. What a pain in the neck. Also, the filter popping out of the ball is only the most recent problem, For quite some time, our vacuum won't turn off unless you unplug it. So here I am. I need my vacuum now since our housekeeper is no longer with us. I am waiting 5-7 days for a new filter to come in the mail so that I can drive the vacuum to a repair shop miles from our house and I'm pretty certain based on other online comments that it's never going to work all that well, while my house collects dust. Anyway, I never post anything on websites of this sort, but how frustrating it is to have spent $500 on a vacuum only to be left with so many hassles and problems. I will definitely not go for a Dyson in the future. I figured at least if I shared my story I could save someone else the trouble.
