Anything will work, what’s most important is regular vacuuming, preventing dirt from working it’s way down though the carpet.

In another life I did some reno work. You could tell who vacuumed regularly, and who didn’t. This was long before vacuums became high-ticket items, they were all generic bag-based ones designed in the 60’s and 70’s.

Not to say some of the newer ones don’t work a lot better, just that an infrequently used great one works worse than a regularly used average one.
