When using our full size upright deep cleaning machines (such as the ProHeat 2X Revolution), typically a 10' x 12' room can be cleaned before the dirty water tank needs to be emptied and new cleaning formula and fresh water need to be added. With our smaller upright deep cleaning machines (such as InstaClean Compact or HydroWave), typically an 8' x 8' area can be cleaned before the dirty water tank needs to be emptied and new cleaning formula and fresh water need to be added. These amounts will vary based on how much water/solution you are releasing onto your cleaning surface.
Some deep cleaners, such as the upright InstaClean Compact or the HydroWave, are better suited to cleaning small areas and everyday messes and spills. If you are planning to clean your entire home, it would be better to choose a full-sized deep cleaner, such as the ProHeat 2X Revolution.
