The "Sub" Heavy-Duty Wet Vacuum Cleaner is equipped with an internal 550W submersible pump, allowing operators to conveniently empty the tank into a drain or soakaway while vacuuming. This feature makes it especially suitable for cleaning areas that have recently been washed down or flooded.

The unit is not recommended for dry applications and the manufacturer advises a maximum suction hose length of 10m to maintain optimal functionality and performance.
