Greetings from GoVacuum.com,
I just wanted to let you know that we are an authorized Riccar dealer, and we can certainly get the replacement wheels for your Riccar 4812 upright vacuum cleaner.
We stock some parts, and what we don't stock we'll order for you. We don't currently have the wheels on our site, but if you still need the wheels, you may email me at [email protected]
We do stock a lot of parts for your 4812 Riccar, including the following;
Riccar 4000 Series Bags That Fit the 4812. Paper Bags 12pk.
Riccar 4000 Series Exhaust Filters for the 4812 Part RF4-2;
Riccar 4000 / 8000 Series Drive Belts Part # A20-R2P
Foam Filter Underneath of Bag Riccar 4812 Part B622-0500
I look forward to helping you if you still need to get the wheels for your vacuum.
