A cordless vacuum cleaner is a portable cleaning device that operates without a power cord, allowing for greater mobility and ease of use. It is powered by rechargeable batteries, which provide the necessary energy to suction dirt and debris from various surfaces, including carpets and hard floors. These vacuums often come with various attachments, such as brushes and crevice tools, to enhance their cleaning capabilities. Many models are lightweight and designed for quick clean-ups, making them ideal for households with pets or children. Their convenience and versatility have made them increasingly popular among consumers.
