Wow, I think that’s a poor design for that vac. I think that model of Ridgid vac is designed to have that top part be removable and used as a blower or something. My other Ridgid vacs have a very large filter that you don’t need to unscrew anything to clean/replace the filter. That tiny little filter on yours probably needs to be cleaned after each use. Thanks for showing where the filter is on that model.
First of all, you are an awesome person and as for the replacement filters, if you google the vacuum and search replacement filter, you might find it online. Thank you so much for watching the video.
