Household vacuum cleaners question?

Oreck XL commercial upright.
It's light, the bags are cheap and the thing will suck the chrome off a ball hitch.
The only downside to them is pet hair.
It will pick it up, no issues there, but it tends to get clogged in the tube to the bag.
The up side is that the tube comes apart easy (in fact the entire vacuum is easy to repair) and clogs are easy to clear.
I've rebuilt probably 6 or 7 of these things I've found in hotel dumpsters and given them away to family. All are working great.
