I really like my Dirt Devil Cordless Stick Vac, but the only thing I would like is to replace the #F110 foam filter. Not that it needs one, but if I could replace it with a new one every so often, I beleive it may last even longer than expected. I'm hoping it lasts for quite a while because its light weight, steers easily, and cleans like a champ. If you can help me with the foam filter, I would be sold completely on the Dirt Devil product line. Thank you and keep building quality products. R. Partin
