Vacuum won't let me push or pull on carpet.

If your Shark Navigator Lift-Away Pro vacuum’s floor roller no longer spins, see the Shark Navigator Lift-Away Pro Floor Roller is Not Spinning problem page for possible causes and solutions.

Because of such a malfunction, I damaged my carpet.

Perhaps I would be able to help you if you described how you damaged your carpet and what kind of carpet you had. I had a similar problem with a vacuum cleaner and a long-pile carpet. Part of the pile from the carpet would always be sucked into a vacuum cleaner. Because of this, I had a flat area on my carpet. I tried it myself but couldn't fix it, so I had to give the carpet to people from https://elegantcarpetrepairs.com.au/carp... who restored it quickly. In my case, it was because the carpet was too old and the vacuum cleaner was too powerful. It is worth considering this if your carpet is many years old.

The red light indicates the brush roller has stopped. Something is caught inside the roller brush. Turn off the vacuum. Remove the object and turn it back on. Green light should turn on. Remember, brush roller needs to be turned on when your vacuuming carpet. If not it will be hard to push.
