The cleaner arrived on Thurs. so I tested it out. It was easy to assemble. It came with a sample bottle of cleaner and a bottle of oxy boost. On the clean water container there are markings for the amount of water, cleaner and oxy clean to use depending on whether you are just cleaning a small area or a larger area. You add the water, then the cleaner and then the oxy boost. This model came with 2 tools. One is the regular style of carpet cleaning brush and the other is called a Deep Clean tool. It has about 16 rubber needles through which the cleaner is ejected. The tool is placed directly on the carpet, squeeze the trigger and the solution is injected deep into the carpet. You then release the trigger and do a reverse stroke to allow the solution to be sucked into the cleaner. It works very well. The dirty water is deposited into a second tank. Unfortunately only about 1/5 of the tank is filled before it has to be emptied so if you were using a full tank of solution in the clean tank, you would have to empty the dirty tank a few times. Overall I'm impressed with the machine.
