Crazy loud noise (by 4 users)

My Bissell Powerforce bagless upright also makes a very loud noise. I thought something was stuck, but I have checked every tube and filter and still can't get it to stop. After only having the thing for six months, the suction is pitiful and dirt and debris collect under the beater bar instead of getting sucked into the tube to be deposited into the canister. The only thing I haven't tried is hitting it with a hammer.

my vacumn makes this loud noise that sounds terrible and like it is going to blow up whenever we vacumn rugs.

I HAVE HAD THIS VACUUM FOR I MONTH AND HAVE USED IT 4 TIMES. tHE HOSE WAS CLOGGED WITH CARPET AND DID NOT EMPTY INTO THE CANISTER. i EMPTIED IT AND NOW THE VACUUM MAKES A VERY LOUD IRRITATING NOISE TO THE POINT THAT I CAN'T USE IT.
