Not a big fan of rotary extractors. They are so slow to use. Sure they
glide over the carpet in the open areas but you still have to bring in and use a wand for edges and corners. Then the extra hasle of a cord really breaks the deal for me.
Most carpets we clean don't have a massive amount of dirt in them, especially enough to show up on the head of the rotary like was shown before. The problem is usually breaking down the oils in the polyester carpet. We use a
crb scrubber on every job. Once properly scrubbed you will have a very hard time convincing me that a rotary will out rinse a carpet.
Keep in mind I don't do any cleaning with the wand. I only use it to rinse out the carpet.
Agree: if you don't use any sort of aggitation besides the wand, a rotary will out clean it.
Disagree: If you are pre-scrubbing the carpet before extraction either manually, with a 175 or a
crb
