Using this Volta Ultima Pet U6011 vacuum cleaner hose is easy. First, locate the machine end with the 39.5mm diameter. Align it with the opening on your vacuum cleaner and use the two opposing push - to - release clips to secure it in place. Then, connect the bent end with a 33.9mm diameter to your standard 35mm pipe. When using the vacuum, make sure the hose is not kinked or blocked to ensure good suction. For maintenance, after each use, remove any large debris from the hose. You can use a long brush to clean the inside of the hose occasionally. Store the hose in a dry place to prevent damage. Avoid pulling the hose too hard or bending it sharply as this may cause it to break.
