Using the Bosch VAC120N is a piece of cake. First, make sure the battery is charged. You can check the battery life on the fuel gauge. Once it's ready, pick up the vacuum. Its light weight makes it easy to hold and move around. When you're cleaning, use the crevice nozzle to reach into tight corners like between furniture or along baseboards. When the canister is full, just press the push - button to empty it. As for maintenance, clean the micro - filter regularly to keep the vacuum working well. And remember, this is a dry - only vacuum, so don't use it on wet messes. If you have any problems, Bosch offers a five - year limited warranty.
