I started in the kitchen. My stove-top would invariably devolve into a mess-top of baked on grease, which had no hope of being removed without a hammer and a chisel. My options were to destroy the stainless steel surface by scrubbing or leave the grime residue for another day. After getting the steamer, within minutes of applying steam the grime and grit desolved and was wiped away with a towel, saving my stainless steel and making it sparkle again. I finally have an easy option for stove/oven management.
I moved on to my tile floor. The grout on my floors had been stained since the day we moved into the house. I had washed and scrubbed to no avail. After a thirty minute cleaning session with this steamer, my grout looks better now than it ever has.
I moved on to my windows. This is the area my children gather like puppies; with sticky fingers, greasy noses, and open slobbery mouths, they create a cloud of goo-art on the glass multiple times a day. I used the window attachment, followed by a polishing cloth. Within minutes the goo-art was gone and my windows were magnificently streak-free clean.
I moved on to disinfecting my floors. The sticky jelly remnant from the day's lunch, the mystery substance that leaked from the trash bag, and the trail of foot-steps were steamed away within minutes.
I've now cleaned cabinets, counters, sinks, refrigerator, microwave, toilets, showers, walls, doors, and molding, and have been impressed with the results all along the way.
I have noticed that after a few uses the dupray steamer started dripping a bit at the beginning of the cleaning session. After a minute or two it stops. It hasn't been enough of a bother to cause me to be concerned with its performance.
There were reviews which criticized the inability to read the water level. I made the frustrating mistake of starting a new cleaning cycle not knowing how much water was in the tank, only to have the machine tell me I was empty within 5 minutes of cleaning. I resolved this issue by emptying the tank before beginning each cleaning session and refilling it, so that I have an accurate measure of how long I can go while cleaning. It's not been a problem since then.
I like the size of the tank. It allows me to clean for a good amount of time while still being easily portable. I love the results. This has been my favorite purchase in home cleaning products by far.
