Using your Volta Lite II U1851 Complete Dust Container is a breeze. First, make sure your vacuum is turned off and unplugged. Then, simply remove the old dust container and replace it with this new one. It's designed to fit easily, so you won't need any special tools. When it comes to cleaning, empty the dust container regularly to keep your vacuum working at its best. The cone filter and HEPA filter also need occasional cleaning. You can gently tap them to remove loose dust or use a soft brush. Always check the filters for any signs of damage and replace them if necessary. Remember, this product is fully guaranteed, but if you have any issues, don't hesitate to reach out to us.
