I use the McCulloch listed on that same page. There are pro's and cons to the steam cleaners, tho. I NEVER use them on a client's hardwoods. They can streak, or worse - swell the wood. They can do a fantastic job on the same, but it's not worth the risk.
I use them mostly in wet areas of the house. The pros here are that it gets the nooks and crannies that other cleaning methods miss. You know, those hinges at the back of the toilet, the rails of a shower, tight spots where even a toothbrush won't fit. It also does a fantastic job on linoleum and tile flooring. I know for a fact that the floors are much, much cleaner than with a mop and bucket. I just change the cloth often with terry shop towels bought at Wally-World for 5 bucks/doz and sewn in half. It's amazing what it picks up. I've lifted it off the floor in front of homeowners to show them - the horror that crosses their face! lol
The cons - it can be cumbersome and a pain in the you-know-what to lug around. But the clean it provides is worth it. The clients rave!!
You do have to wipe up everything you steam. Don't believe that you can just steam it and go. That's hype. OH - it works wonders on water-safe items that have little nooks and crannies as well. I use it when I detail clean/dust.
As for the hardwoods, I use the Bona mop. Different clients want different solutions, but the mop with a replaced solid handle works well. Again I purchase extra microfiber cloths to fit - this time off of Ebay. They're about $25 with shipping for 10. The ONE that comes with it - now who mops their entire house with one cloth??!! Even a homeowner would need many more than one - let alone a cleaning company. I change them often as well. The beauty is, you drop the moistened cloth on the floor, put the mop on top and off you go! Very little time fussing with equipment- more time cleaning.
My last bit of advice - I would never purchase just the floor cleaner when you can purchase for the same price one that does it all. Just MHO.
