The advantages of the Vswab over the former or square format swab comes from its unique letter "V" shape. This shape has several advantages over the square format swabs currently in the market. For example, the narrower edge of the V shaped swab minimizes the contact between the swab and the chamber wall. This ultimately eliminates the lint produced inside the camera eventually from falling on the sensor.
Another advantage of the Vswab is a better maneuverability and easy swabbing while inside the chamber. Due to its triangular form The Vswab applies equal pressure to the edge of the swab pad. This brings a more homogeneous swabbing motion and less streaking along the edges.
