Bob just cleaned our carpets and I am very pleased. NO STAINS ANYMORE, YES! We had a particularly nasty one that came with the house (even though the rugs had been cleaned before we bought it) and it is finally gone.
Truly the rugs dried very quickly and the house smells so fresh, not that perfumed cover-up that other carpet cleaning companies do. Also we have allergies to most fragrances and have had no trouble with this process.
If there were a rating system from 1 to 5, five being the highest rating I would give him a 5!
This is not a paid advertisement, I just like to give praise where it is due.
