I have a one time remodeling project that will involve hanging ten sheets of drywall. Given the quote I have received, I can justify in my mind buying a Planex Easy. I know that the CT 36AC is the recommended vacuum, but I own a CT 26. I also know that drywall dust will reduce the usable capacity of the CT 26 filter bags by 75% and will clog the HEPA filter. The cost of a new filter and extra bags is still less that the cost of a new vacuum that is only available in a size I do not want. My question: Will drywall dust permanently damage my CT 26, or will it just increase my consumables cost? Thank you for your help.
