A **cordless stick vacuum** is a lightweight, battery-powered cleaning appliance designed for maneuverability and convenience. Unlike traditional upright models, it features a slim, “stick-like” profile and operates without a power cord, allowing users to move freely between rooms and reach high or tight spaces without being tethered to an outlet. These vacuums typically use powerful lithium-ion batteries and cyclonic suction technology to collect debris into a bagless canister. Many models also feature a **2-in-1 design**, enabling the motor assembly to detach and function as a handheld vacuum for cleaning furniture, stairs, or vehicle interiors.
