I bought one of those steam cleaners years ago. You know, it's supposed to superheat steam and clean everything?
Well the model I got took forever to heat up - but it had no "throttle". Meaning, once it was on, it was running constantly until it ran out of water.
Period. How stupid was that? Worse, it didn't even come close to doing the job, the hoses were flimsy, there were warnings about pressure if you should
open while it was running and you could not add soap or a cleaner without breaking it. Complete waste of money.
NEVER ordered an As Seen On TV again unless I could actually look at it.
Oh - got one of those shrink hoses. They work, but if you have lousy water pressure, they're kind of useless.
