The Importance of Grooming

"Finishing (Grooming) Principle - The term "finishing" refers to any procedure that enhances the appearance of residential carpet beyond the physical soil removal process, to improve end-user perceptions of cleanliness. Finishing seldom is required on commercial carpet styles and it contributes nothing to cleaning or soil removal. Where appropriate, however, it contributes immeasurably to end-user perceptions of cleanliness. Generally, pile setting or grooming employs one of several finishing or pile-grooming tools (carpet groomer, brush, or comb) specifically designed for this purpose."
