If the Swiffer wetjet is not spraying as required, you may need to check if it has batteries and if they are functioning. Look at the back where the cleaner goes in, there is a tab. Push the tab down and pull to your side. There you will find the compartment with batteries, where you should fit 4 AA batteries. In most cases, you need to provide the batteries for yourself.
