Query: Wow

I've had this vacuum cleaner I got from Sears years ago and I didn't like all the dust that was coming out of the worn connection where the bag attached so I looked in Consumers Report and noticed the low price for this one and read the good reviews on Amazon. Thing showed up promptly, again a pleasure dealing with Amazon, and I vacuumed the carpet I've vacuumed a million times with the Sears and I could not believe how much the Sears had been missing and how fast the bag on the Hoover filled up. I ripped open the filled bag and there was years of [..] in it, skin cells, dust, cat stuff, all kinds of yukkie stuff that the Sears did not pick up. I don't have much experience with vacuums, but considering the double filter in this one, the nice attachments and how well it works and the dirt low price it's a winner.
