The PondHero Sludge Muncher will suck up the dirt and debris from your garden pond. It matches up with the specification of other competitor pond vacuums on the market but at a much lower price point. It is designed to be operated pond-side and works on a cycle operated by a float switch.Directions for use:- Ensure the vacuum is HIGHER than the level of the pond- Simply push the suction nozzle towards the part of your pond you want to clean & watch as the dirt is sucked away and your pond begins to clean.- Once the pond vacuum reservoir is full the motor stops automatically allowing the dirty water to run away to waste. (the vacuum must be HIGHER than the area you are discharging the water to) - Once the chamber has emptied, the vacuum will re-start the cycleThe unit also has the benefit of a secondary 'indoor' mode - here the motor remains on and there is no timer valve in operation. Now any dirt will be picked up and stored in the vacuum bag (provided). NOTE: Wheels not included.
