- Thanks to the AS 2 battery, the water tank uses the battery-powered pump head which constantly applies pressure. It has a funnel-shaped easy to fill 10-litre transparent tank with a level indicator on the container, so you can make sure you don’t overfill it too. It also comes with a pressure relief valve and 4 m water hose with standard coupling.
- Fitted with a soft-grip carrying handle, it has a battery cover which provides protection from water, liquids and dust and is IPX4 rated – meaning it is protected against water splashes and can be used in all weather conditions.
- It’s easy to operate too – simply click the power button to turn the WSA 40 on, then adjust the pressure to your desired setting using the dial.
- A built-in sleep mode detects when the machine is no longer in use, or the container is empty, which helps to save battery life. A battery charge level indicator is located on the machine here.
