The filters are reusable and should be cleaned regularly using the included cleaning brush or rinsed with water. Optimum dust collection will only be achieved with clean filters. NOTE: After rising, allow filter to dry before placing back into the vacuum. Do not expose the vacuum cleaner to rain or wet conditions. Water entering the unit will damage it. Do not pull or yank on the power cord. Store the vacuum cleaner away from hot surfaces or under direct sunlight to reduce the risk of a short circuit.
