Okay, here are a couple of links that should be helpful:
Euro Pro Replacement Cover LC and Pad for EP1010 / 1005
This will link you directly to the purchase page for the ironing cover you want. Sorry, but after extensive searching, it's the only one I could find, so I suggest you get two while the getting is good!
Customer Support for Sharkvac Products - sharkvac.com
This link will take you to a web page that will allow you to send the manufacturer an email explaining the part you need. Please, before you send the email, try your best to find your manual and see if there is a part number listed for the part you want. If not, and the old part is available (like—if you have a broken one), check it over thoroughly (perhaps using a small flashlight and magnifying glass to make sure you don't miss it) for any numbers that might be stamped, embossed, or etched into it. Even if they are not part numbers, they may help the manufacturer to locate the one you need. No matter what, send them as much information as you possibly can in order to help them be able to help you—the easier you make it on them, the more likely you are to get satisfactory results.
Finally, here is a toll-free number for the manufacturer's tech-support line: the same "homework" applies before you call it:
1-800-798-7398. Hours are Monday through Saturday from 9:00am to 6:00pm Eastern Standard Time.
I hope this helps!
