Using this reusable cloth bag is easy. Just install it in your Taski Vento 8, Vento 15, or Bora commercial vacuum cleaner following the normal procedure. When it gets full of dust, simply remove it from the vacuum cleaner. You can wash it with mild detergent and water, then let it dry completely before putting it back in. Make sure the bag is properly attached to avoid any dust leakage. Also, check the bag regularly for any signs of wear and tear. If you notice any damage, it's time to consider getting a new one. This way, your vacuum cleaner will always work at its best.
