i am a bit of a germaphobe but want to avoid using chemicals as much as possible so i got into steam cleaning a while back...started off with a mop off QVC and have since gone on to get a domotec. i have found the qvc products seem to do all that they are supposed to on the demos but they never declare what bar pressure they perform at and so do not believe they will be very robust, have a continuous steam and a pressure that will make it a worthwhile product to use. other products can be v expensive but they do last and the level of cleaning is so impressive it is worth the cost.
