Only have a sec here, but have to say that rereading my post, it sounds like I used it for a month or so, then it broke. but that's not the case, we had it over a year or two in the old house and I used it to clean a TON, then when we moved I broke it after the kind of abuse stated above. I do think under normal use, and the way the instructions very clearly tell you to use, LOL, one of these very expensive machines have a very long lifespan. And if you were somewhere you could buy it locally or at least regionally, they probalby would service or repair for you. This was all more complicated in my case b/c I had moved to Canada, but bought used in the US via ebay, and it wasn't even certified that it met Canadian electrical standards, so anyone opening it up here would be liable or something...
anyhow, I really wouldn't worry about durability, despite my issues. If you want to test, I know when I was obsessively researching this stuff 5 or so years ago, I had read of people who were in the region of a Ladybug rep, they would come to your house and show you the thing. Because it is super expensive, lol! Anyhow, I think anyone who could get their hands on one of the good ones (vapor cleaner, not steam cleaner, I think is the distinguishing terminology) would be in LOVE. but the one I want costs about 1000 bucks! YIKES> I wish I could get into a cooperative group to own one--like a local group of co-owners, lol! Good luck, mama!
