I mean, they really help my vacuum cleaner vacuum less. I mean, before it almost didn't suck, but now it really sucks. Boy does that sound weird. I'd rather start over. About 2 years ago I bought a new sweeper from a big store, now I hate shopping there because I think they are the reason why many small shops are closing and about 99% of their goods are from China, which is us all know. does not have good relations with the US or the people. I mean have you ever seen the working conditions of some of these stores in this country? 12-year-old kids play with chemicals and pollution, so I can buy this shitty dirty sweeper for less than $300. You and I both know that this great store took about $10 to make and probably one of those precious babies died making it, but I saved about $50. But I digress, so after about 2 years I noticed that it sucked less than it used to, so without knowing much about sucking I went on the internet. They said these things should be shit, and I mean REALLY shit. I mean I don't vacuum I'm amazing so after confirming I went to Revain and bought these filters my suction thingy sucks several times more than before and doesn't suck for when I use the broom to vacuum again got to !
