This is an average carpet in an average house with dogs. If you have dogs and carpet, yours looks just like this. I don't care what vacuum you have or how much you use it. You need a carpet rake.
You should rake the long hair first. Vacuum rollers pick up the hair, and you have your cut it out of the roller after the bristles stop working later.
I got two of the little handheld ones because i have two cats. I can completely get most of the hair up, and it's all back 3 days later, so if you're not regularly removing pet hair, and maybe long people hairs, you're not getting your carpet at clean ass you expected, hair wise.
I have a vacuum I bought especially for pet hair. I also have a large carpet cleaner. The rake is better. You may not see it, but it's there. Get a rake.
It's a rubber carpet squeegee. I have one of these, but not the exact one shown. It's excellent at gripping hair out the carpet. But it takes a strong arm work out.
Yes, my vacuum works. Maybe its not perfect but i almost catch every hair in the carpet.
And i have to say this carpet in staged or wasnt cleaned in decades.
