Purchased my steamer to kill the bugs brought home from the local hospital stay. Nightmare. I tried pesticides and natural methods. I even had the house bombed twice. The only things that seemed to work on my peace of mind was steaming everything at 300 degrees, vacuuming with my new Heppa vacuum and using Kleen Green to dust all the shelves. The Dupray Steamer was and continues to be used on a regular basis. I used it Daily for weeks and now a few times a month. I am down to once a month and I steam couches, carpets, drapes, curtains, beds, pillows, car interior and carpets. It doesn't really work on stains when comet works faster. I also steam drains and air ducts, lamp shades but careful not to melt the lining underneath. Peace of mind has been achieved because of this amazing sturdy product by Dupray. I have used this steamer consecutively hour after hour until I have finished. I have to wait 20 plus minutes to cool down before filling up again but for fifty percent the savings so worth the expense for this older model. Wouldn't trade my Dupray steamer for any other brand. I have had no issues with the parts melting, everything is sturdy and strong and holds up to constant use. Very Dependable. Thank you Great Offer Stock for providing this steamer for the price I could afford.
