Attach Cyclone to a hose using the hozelock connector. Add filter cleaning liquid into the chamber (Instant cartridge cleaner is quicker).Use the trigger and spray the cleaner/water mix into the filter using the brushes to remove any unwanted debris. Once the cleaning liquid has been used up leave the filter to stand for at least 1-2 hours (10 minutes with Instant Cartridge Cleaner). Then without filter cleaner liquid just use the water spray and brush to remove any remaining dirt. Repeat this process on a monthly basis.
