Using the Makita XCV11Z is quite simple. First, make sure you have a fully - charged 18V LXT® Lithium - Ion battery. Insert the battery into the vacuum, and you're ready to go. You can choose different nozzles according to your cleaning needs. The wide nozzle is great for large areas, while the crevice nozzle is useful for narrow spaces. When using it, keep in mind that the battery life is up to 60 minutes with a 5.0 Ah battery. If you notice the suction getting weaker, it might be time to clean the filter. The filter cleaning system is designed to make this process easier. As for maintenance, regularly check the filters and clean or replace them as needed. After each use, empty the 2 - gallon container. Store the vacuum in a dry place to prevent damage. Also, when using different batteries, ensure they have the star symbol for the best performance and protection.
