Some cleaning professionals prefer bonnet cleaning because it’s easy and inexpensive. However, this method is controversial in the industry because it can leave soil behind in the carpet. Also, the process may flatten and damage carpet fibers.
Carpet manufacturers, especially those who manufacture Olefin carpets, advise against bonnet cleaning. This type of cleaning may actually void some carpet warranties.
If cleaning professionals are going to bonnet clean, it’s best used as interim maintenance between deep cleans.
