What an incredible little machine! I ordered this mainly due to the fact that my home I recently bought needed a thorough cleaning especially the window sliders. Wow I was so shocked to see the dirt that was in them and then how efficiently the Neat Steam cleaned them out. Now the windows in this older home look and work so well.  The windows that were hard to open now run so smoothly! Amazing. I also tried the window cleaning attachment and the windows are crystal clear. HIGHLY RECOMMEND THIS! A must in your cleaning gadgets . See photos you can see before and after.
