The Amerivap Steamax Steam Cleaning System is not a continuous fill. This is because the steamer pressurizes the tank to create the PSI and the proper temperature in the boiler, so opening it would release the pressure. When refilling with water it should only take 8-10min for the refill time to re-reach the max temp of 290 degrees, and if you are using it on the medium setting, you should get 1-1 ½ hours of continuous run time from one tank.
AmeriVap Steamax Steam Cleaning System when directed into cracks and crevices along baseboards will kill bed bugs that are contacted directly during steaming.
