Cleaners’ Henry left lines on my good carpets

I recently paid some well-reviewed cleaners to clean my house ready for estate agent photos. Mostly they did a good job, but they used a Henry vac which has left lines all over my better quality rugs and carpet. (Doesn’t show so much on the old worn ones.) I can’t erase them with re-vacuuming or a carpet sweeper or walking over, and I’m rather annoyed. I’ll try shampooing the rugs, which I can move, but does anyone know a remedy for getting Henry lines out of a newish carpet please? It looks as if a toddler went wild in there!

Thanks. Or is this a thing I don’t know about and people like them?
