Maybe you have already tried these suggestions, but here goes:
1. Inspect the vacuum tube for contamination. If the felt is dirty wash with a dishwashing detergent and rinse with distilled water.
2. I discovered that using the vacuum cycle for more than 3-4 rotations causes static charges to build up on the LP which in turn attracts dust partiles
