A window squeegee is a tool used to remove liquid or debris from smooth surfaces, typically windows or mirrors. It consists of a blade made of rubber or silicone, which is attached to a handle. The blade is pulled across the surface to be cleaned, forcing liquid or debris off the surface and onto the blade, which is then wiped clean.

Window squeegees come in a variety of sizes, typically ranging from 6 inches to 24 inches in width. They can also have different blade materials, such as rubber, silicone, or a combination of the two. Some squeegees have replaceable blades, while others are designed to be disposable.

Window squeegees are commonly used by professional window cleaners, but can also be used by homeowners for cleaning windows, mirrors, shower doors, and other smooth surfaces. They are especially useful for removing streaks and leaving a streak-free finish on the surface being cleaned.
