Where to buy HV301 replacement parts

Hi all,

I have a Shark Rocket HV301 and the bottom hose has multiple cracks reducing suction. I

I’ve temporarily patched with duct tape (ANOTHER use for duct tape), but cannot find a replacement part lower hose for HV301 after searching with Google and looking on Amazon AND Ebay (other models, but no HV301).

Suggestions where to buy AND part number would be GREATLY appreciated.

BTW, the tutorial for replacing the hose I found on ifixit.com looks EXCELLENT - just need the part.

Thank you ,

IRA BARNETT
