Cordless vacuum cleaners are portable cleaning devices that operate without a power cord, allowing for greater mobility and ease of use. They are powered by rechargeable batteries, making them ideal for quick clean-ups and hard-to-reach areas. Many models come with various attachments for different surfaces, such as carpets, hardwood floors, and upholstery. These vacuums are lightweight and often designed for convenience, making them suitable for everyday cleaning tasks. Popular brands like Dyson and Shark offer a range of cordless options, featuring advanced filtration systems to capture dust and allergens, enhancing indoor air quality.
