Can i buy a new dust cup for my 301
These seem to be the only accessories available for the 301: https://www.sharkclean.com/search/?q=hv3…
Shop around. You can’t always rely on the traditional suppliers for some parts, sometimes you have to go outside the usual ecosystem and find an independent supplier. I found a replacement part for you on eBay: https://www.ebay.com/sch/i.html?_from=R4…
