IF THE FILTER HAS BECOME BLOCKED
Filters should be cleaned regularly to ensure long life of the product and high performance levels and should be cleaned anywhere from weekly to monthly depending on the frequency and the nature of the vacuum usage.
To clean as blocked filter, it is recommended to remove the filter from the product and take it to an outside bin, tap the filter on the inside of the bin to remove any loose dust and debris to the best of your ability.
Hand wash the filter in clean water at no more than 30 degrees regularly changing the water until it runs clear, try to avoid using detergents as some can have an effect on the filter which may cause deterioration.
Air dry the filter overnight or until completely dry (24 hours recommended) before replacing it into the product for use again.
THE HOSE OR INLET HAS BECOME BLOCKED
If the inlet becomes blocked, use pliars or a grabbing tool to retrieve the blockage.
If the hose has become blocked, remove the hose completely and turn it around so that the opposing end now meets the suction inlet, switch the vacuum back on and this will often shift a blockage.
If this does not resolve the issue take the hose outside and using a mains water hose or outdoor tap, run large volumes of water through the hose in the opposite direction that which the suction would travel.
