Vacuum Cleaners Discussions

I've been using various vacs (canister w/PN; suction only canister; shop vac & old Hoover Convertible) 4 vacing apartment hallway carpet that hadn't been vacuumed at all I was using a Ridgid shop vac w/Cleanstream HEPA filter & Casa Vacuum HEPA bag & a rug nozzle like this: https://www.ebay.com/itm/352767499301?hash=item522294dc25:g:9xAAAOSw-eJbwhCf&amdata=enc%3AAQAHAAAAoOxUZNuVlBUMXs%2BEfWCGg0Ar2Fp2HkfQjwYikbsbWUqA%2Fk1UyPKXc5By3bjoCG0eMqthRlYJGPEqrTkTLvCs5KAul2RLBhNup5ZUUvuNP45rvYp5oX7pgTjeTmhWHFSyl4JQ5LkzcjKQL7ly%2FHJ0lvWdkyXDC8dNm36%2BuV93fIKhca4wND6HKRSo4a%2BDfUjr9jzbq%2F3%2BDORBSxk33XSgUcI%3D%7Ctkp%3ABk9SR-rh0fXgYA & only got a bit of dirt before the bag pores clogged; changed the bag only 2 repeat this pattern Then I used a upright like a Hoover Convertible (using bottom fill style C bag) thinking the 'beats as it sweeps as it cleans' would work but only 4 a short while Seems like I'm picking up fine black 'soot type' dirt What vac will work on situations like this? I might use the Ridgid 4 above floor vacing & get a Kirby or Sanitaire?
