Riccar R30 Tandem Air Vacuum 

That is an amazing vacuum!

Excellent explanation! Thank you!!! Have you ever known of a residential company to use these?

Minor Correction: The R30D.8 has 2 warning lights; full bag and stopped roller brush. It does not have a "filter" light. The filter light is on the R40 model only.

assembled in is not the same as made in the us (not all parts are made in the us)
