A:Answer Yes usually dilute a liquid floor cleaner with warm tap water. If you use too much cleaner, you may develop a foam over your cleaning area. Also, we found that over a period of time, both plastic reservoirs turn cloudy according to which cleaner you may use. You should clean the dirty water reservoir and the bottom of the machine after every use if you want to keep these items from having an odor due to what you may have cleaned off the floor. If you have pets, the brush area and plastic cavities will need to be cleaned due to the dog hair/fur that was sucked into the machine with the water.
