I don't have any hardwood floors in my place, so I can't give you an opinion on the floor buffing capabilities, but I can tell you about the carpet shampoo system which works great on my carpets.

If you follow the shampoo instrustions to the letter and don't try to cut any expense by using other than Kirby shampoo products, you will get excellent rersults too.

You see the Kirby shampoo system was designed as a dry type carpet shampoo system. Other brands of shammpoo will leave too much water in your carpet after you finish giving poor cleaning results. The Kirby shampoo dries to a fine powder which is designed to attach itself to the dirt in your carpet. The final step is to vacuum up the powder and the dirt that is attached to it. For the best results, make sure your Kirby vacuum bag is less than half full which will provide maximum airflow and suction to remove the powder/dirt mixture.
