I have a Ladybug 2300 with the TANCS option. YES pricey. Very! It works really well and I like the continuous fill system. It's bulky but maneuvers easily. I also really like the Formula 212 cleaner that is meant to be used with (not IN) the Ladybug. It has lasted me a very long time, and I use it as an all-purpose cleaner everywhere.

The Ladybug is an excellent choice, but is one of the most expensive steam cleaners on the market. They usually cost $900+. Another good steamer you can use is the McCulloch MC-1275 Heavy-Duty Steam Cleaner which will cost a little less than $100 and has numerous positive reviews and ratings..
