I don't misuse them. I simply turn them on, vacuum the carpeted floors in my apartment, and promptly turn it off and store it in the laundry room. I have now had to purchase 3 vacuum cleaners in a year because they all have the same problem. They just stop picking things up whatsoever; however if you use the attached hose it sucks everything up. There are no clogs and nothing is wrong on the bottom in appearance. Help!
First time it happens again, don't buy a new vacuum cleaner right away, but go back to the shop and tell them about the problem. They should try to help you, because it's their product that sucks (no pun intended) and they want happy customers.
If the hose still has suction but the carpet beater doesn't, there must be a clog somewhere or the roller has stopped rotating. Keep looking. Turn the vacuum cleaner upside down so you can see the bottom, turn it on and see if the brush spins. If not, there's your problem. The belt has come loose, which it shouldn't do that quickly, or something has gotten jammed and is preventing the brush from turning. It's usually long hair, or threads from the carpet or something. Unplug the machine and clean what needs cleaning.
Most vacuums have filters. If your filter is dirty, the vacuum's suction power will diminish greatly. The power through the hose has probably decreased as well, but it is not as noticeable because the hose has greater suction than the bottom. Put your hand against the hose and see if it will hold your hand tight against it. If it is very easy to pull you hand away, you have suction issues all around. Look for your filters and clean them.
