How do I replace the wheels on my Vax pet2? - Vax Vacuums

I would try www.espares.com

Although there are Vax Carpet cleaner YouTube videos about changing belts, I can't narrow down which one might apply to you. That said, the Vax support page offers a way to drill down into manuals after you supply a serial number which they show you how to find. And they offer a chat as well.

You need to contact Vax directly.

Go to this site, they offer free support:
Vax Dual Carpet Cleaner

You need to list the model number to this vacuum and be more specific with your question.
'fix the wheels back' is very unclear.

I have seen them on ebay

Hi There, If you are talking about the Vax vacuums that are looking a bit like R2D2 (bucket on wheels) the most likely cause is a short in the power cord. It is easily fixed by shortening the cord by 30 cm. If you are not comfortable shortening an electrical lead any electrician or repair man will be able to do it for you. A second possible cause is a faulty switch. A distant third possible is the motor itself has failed.
The motor really should only be replaced by a technician unless you are very comfortable playing with this type of repair.
