I am looking to get a vacuum for my older doughboy. I have the one I used on the old intex, but not doughboy. I don’t need one that works by it self, just one I can manually use. Any suggestions on what to look for? yhere Is a port on the skimmer inlet for one. Standard doughboy skimmer. Are there ones that have a large collection bag? Do most vacuums dump everything into the filter? I am trying to lean more as I go. Thanks
