DIY carpet shampoo w/rented equipment?

[NationalMatch]

Does it do the job? Or is the equipment so worn out it's worse than nothing?

If carpet shampooing is good with rented equipment, what pitfalls do I want to avoid? What do I want to include?

Note: it's not "whole room" stuff. It's "traffic pattern" stuff. And, no pets, no kids, no friends. I.e., no stains. Just matted down carpet in traffic patterns.

Edited to add: When I "google" the subject, I get automated responses by carpet cleaning companies and how much can go wrong unless I hire them. But, I trust OSA. Sort of.

In my experience the equipment is usually fine and it does a good job of pulling the dirt out of the carpet. As far as restoring it to like new after you’ve let it get to the point where the fibers are all matted? I’d say keep going over it with the brush/beater-bar and it will get better but don’t be looking for “like new” results.

Pay a professional service. Zerorez is the company I want to try.

It is only my opinion but, experience showed me once the carpet is matted down the fibers are breaking down and it will not recover.

I have used the commercial cleaning equipment and it is satisfactory. Bought a cheap Bissel and it was slightly less but cost me less to operate after second use.

Had good results with the low sudsing modern laundry detergents just did a second pass with only water.

When in my own home all carpets came out and tile and pergo went down.
