Kenmore vacuum cleaner causing carpet to melt

Hello,

For the last 6 months we have noticed spots that looked like glue

stains on our carpet. We could not figure out were they came from. We

used a commercial carpet cleaner to see if we could get rid of these

spots. I did not work.

Every month a few more appeared. Then we finally put two and two

together and figured out that our vacuum cleaner was causing this.

While using the vacuum cleaner I looked behind me and noticed three

large spots that were not there before I started to vacuum that day.

Since the spots were larger I could tell that the carpet had melted.

I would like to know from if there are any other complaints like this

out there so that I have something concrete to complain about the

Sears. Our Kenmore vacuum cleaner is model number is 116.22749C

Purchased in Oct.07

I would grateful for any comments or suggestions.

I have noticed several melted spots on our berber and frieze carpets. I assumed that the brush bristles are very stiff and we left the vacuum in one location for too long. I have searched for a replacement brush with soft bristles, with no luck. I found an interesting thread with several experiences:

From thread: "What *did* work and created a new melted area was

touching the head lightly to the carpet for just a few seconds.

Apparently, a very light touch -- which occurs occasionally during

normal vacuuming, depending on height setting -- allows the carpet

fiber to remain standing without slowing or bending the brush

bristles, and this friction leads to very high temperatures very

quickly." I plan to replace this vacuum when I have the money....the next one WILL NOT be a Kenmore. Tim
