A cordless vacuum is a cleaning tool that sucks dirt, dust, and waste products from any surface. It is most often used in areas where dirt can easily get stuck. Examples of these are floor corners, stairs, and carpets. It works similarly to other vacuum types, except it does not have a cord. This feature gives you more freedom to move and clean places that are far from power outlets. Since cordless vacuums do not use electric cords, it is powered by a strong battery source instead. These batteries can be recharged in a standing port when you are not using the device. Source: https://western.com.ph/blog/cordless-vacuum-cleaner-philippines/
