The technician was very knowledgeable and helpful. He didn't try to push any upgrades -- he merely suggested -- there was no pressure. Every time Pristine comes to clean I learn something more about carpet care.
This is the second time I have used Pristine. The first time was with a GroupOn. This time it was to do just a couple of rooms to deal with the "mud-season" that gets tracked in after the winter -- when everything is melting. They are very professional and I would recommend them highly.
