Getting your Big Brute Wet Sucking Again
You've just emptied your Big Brute Wet out of the dump valve on the back and it's suddenly stopped sucking.
Make sure you close the valve afterwards!
If you leave it open and start cleaning up again, it'll suck air back up through the valve and not up through the suction hose. It'll seem like your Big Brute has inexplicably lost all its suction.
It's a surprisingly common mistake and luckily it's a very simple solution.
