if your gonna use carpet powder then a dyson isnt a good idea. The little holes in the machine get messed up.
So i ended up getting a vacuum at sears a kenmore progressive vacuum it has vacuum bags that need to be changed every so often. I love to use carpet powder. We got it on sale for 199.99 affordable price thats just my opinion. Oh yeah, you can get it try it out for a month and return it if you dont like it.
