We have found that the best way to keep the Snow Blow Cannon working its best is to carry out simple maintenance procedures.
Make sure to thoroughly rinse out your Snow Cannon bottle and Happy Ending Cannon Bottle before connecting them to your cannon. Any debris that has settled in here can block your cannon. It's especially important to rinse out your Happy Ending Cannon Bottle as any residual product that has been allowed to dry in the bottle can cause a blockage once mixed up with water.
If you ever drop your cannon in dirt or sand, make sure you give it a thorough rinse off under the tap, particularly the adapter. Any dirt jammed into the adapter will be pushed through the cannon and clog it immediately.
Running fresh water through the cannon after you use it will also help keep the internals clean and clear.
