Pros: Works great on tile.
Cons: A little pricey, but the $100 off coupon from Oreck helped.
We recently rented an oreck Orbiter ultra to clean our carpets and ceramic tile (got a free rental coupon from Oreck) We used it on our carpets along with Capture carpet cleaner from Lowes. Worked Great, better than steam or other cleaners. The real difference was on our ceramic tile. We cleaned the tile and grout using Simple Green (non-toxic and biodegradable), scrubbed it with the orbiter and cleaned up using clear water in our hoover floormate. Fantastic job, floor has never looked this good since it was new, and the grout is much cleaner. We ended up buying the orbiter along with $100 off coupon from Oreck. Would highly recommend this product if you have tough tile cleaning problems.
