Ho. Trying to figure out a solution. Getting a lot of acorns now, cannot cut the tree... My Polaris vac bot is filling up daily, but i am not at the house on weekdays... So I need some sort of cover. Some a orns can fall in, but I need to catch most on top. Or get a bigger Polaris back or bigger robot. My Polaris mess back has Velcro, not a zipper and would say it s about the size of my forearm when full. Any ideas for a light duty cover for these last two weeks of my season.
