I have ordered replacement rollers and belts for my Late Winter 2021 Bissell Proheat. I ordered them in advance, thinking that the ones currently in use would need to be replaced this year. , and I would replace them with the current ones at hand. Bad choice on my part, I think I should have tried installing them straight away although the old ones were still good for a few more monthly cleanings. Of course, I know that they cannot be returned now that the return window has long since closed. My only warning is when you order, double check the sizes of the rolls with your used ones right away.
