Unlike upright vacuums, they feature a separate motor and dirt collection canister connected to the cleaning wand by a flexible hose, allowing for greater maneuverability and reach. This design makes them ideal for cleaning stairs, under furniture, and tight corners, as well as a variety of surfaces, including hardwood floors, carpets, and drapes. Many canister vacuums come equipped with HEPA filters to capture allergens, ensuring improved indoor air quality. Their lightweight and ergonomic design often make them a preferred choice for tasks requiring extended use.
