The bag on my 280 has holes coming in it near the Velcro. It is a month old. Any ideas?
Sounds like manufacturing defect, I would return it, or contact Polaris for a replacement.
Make sure you bag is being secured to the hose at the top so it stands up properly. I have seen many of them get caught around the wheels and drive mechanism and wear holes through in just a couple of uses. there should either be a plastic collar around the hose for a small velcro tab to go through or a larger tab that waps around the hose itself. Hope this helps.
