HOOVER U9125 990Z VACUUM CLEANER

[URCHASED THIS MACHINE 6 MONTHS AGO AND NOW IT IS TOTALLY DYSFUNCTIONAL. IT MAKES A LOT OF NOISE, BUT CANNOT PICK UP EVEN THE SLIGHTEST BITS OF DUST, SCRAPS OF PAPER OR EVEN DUST THE OAK FLOOR. OUR HOUSE HAS OAK FLOORING EVERYWHERE SO WE USE ORIENTAL RUGS SCATTERED ABOUT. WE TAKE OF OUR SHOES WHEN ENTERING THE HOUSE IN FAVOR OF SLIPPERS. I BOUGHT THIS MACHINE BECAUSE I WANT TO PRESERVE THE ORIENTAL RUGS. IT HAS NO EFFECT UPON ANYTHING. INCREDIBLE THAT A COMPANY OVER A HALF CENTURY OLD CANNOT PRODUCE A SIMPLE DEVICE LIKE A VACUUM CLEANER. THIS IS NOT ROCKET DYNAMICS. THEY SIMPLY DID NOT TEST THE MACHINE. WHAT COULD BE WRONG?
