Hello John Slife,

I searched the internet high & low (UK &USA) ...

I even found your question to them about a week ago...

I could not see your answer... but I can tell you I found nothing.

By this time I would usually have a good idea of the color, style & options... All (I think ... is it was a 2002 model year)...

Unsure results:
ereplacementparts.com your number resolved to a DIRT-DEVIL BAGLESS UPRIGHT... But the two items YOU ARE INTERESTED... their Micro-Fresh perma (cylindrical) filter...
and the wheel set... both show as discontinued...

2860211000 Microfresh Perma Filter Assembly

My advice would be to go to their site and speak to their help... or a local vacuum shop. A good repair person can often find viable ALTERNATIVE parts based on your actual needs.

Sorry... not much help

SEARS brags a lot... I remain unimpressed but you COULD give them a try
