I use this vacuum cleaner to clean my desk and small dirt on the floor or carpet. It's durable and well built. This should take a long time. The battery seems to last longer than I expected. Press the button on the side and gently pull the yellow top up and off to replace the battery. It has an easy-to-clean inner basket filter. Just press the button on the side and remove the top. The power button is located under the power button. Just slide it to turn on and off. For cleaning computer keyboards with high keys, the suction power could be higher and the bristles on the bottom could be a little longer. I would recommend this product due to the limited suction power. I use it daily.
