I rinsed all 3 filters and left them by the back door to dry. After about 5 days I deemed them dry (well, dry enough....) and put them back into the sweeper. I shut it back up, and parked it in the closet.
I pulled it out yesterday ready to sweep my floors. I have to admit, I was a little excited. "New, clean filters! Oh baby! This is going to be awesome!!"
I started the sweeper, and within seconds the room filled with the most putrid, horrid smell. Imagine a combination of week-old sweaty socks, dirty diapers, and rancid soured milk. My children ran gagging to their rooms, and I just about fainted.
Washable filters, my foot.
