This video this company uses a bonnet pad to do the cleaning. It always ends up with what the customer wants and expects at the end of the day. With this technique you just won't get the deep clean in my opinion. Yes he is picking up soil but without and extraction with suction and use of a deep rotary brush you can't get into the secondary fibers to capture the finer soil particles. Some people still do it this way but i feel times have changed and there are way better procedures to get a deep clean rather then a topical one. If you need carpet or tile cleaning please give us a call.
