My Shark AZ910 anti hair wrap / lift away is about 4 years old. Gets heavily used, dog hairy house and dirty muddy kids hobbies.
its stopped picking up properly, got to go over the carpet several times to get sock fluff and dirt. I’ve washed all the filters and roller, and checked all the pipes. I’ve even tried a new floor nozzle. Any ideas please?
any advice welcome, I don’t really have funds to buy a new one. thanks
