Using this Milwaukee 14 - 37 - 0105 replacement hose is easy. First, connect the hose to the main unit of your Milwaukee 0880 - 20 Vacuum. Once it's securely attached, you're ready to start picking up dust and debris. When using, make sure the connection is tight to avoid any air leaks. As for maintenance, it's a good idea to clean the hose regularly. You can use a mild detergent and water to wipe it down. Just avoid using harsh chemicals as they might damage the black plastic material. Also, keep in mind that the nozzles and connecting pipes are sold separately, so take care of them properly too. Store the hose in a cool, dry place when not in use to keep it in good condition for a long time.
