By locking them together facing opposite directions, you can quickly wash the window with the scrubber, then turn over to squeegee the soap, water and dirt quicker than you can imagine. Or, place the squeegee facing the same direction as the scrubber and wash and swipe in one motion. You can use them individually as you would a separate scrubber and squeegee, but store them easier by locking them together. Now that they will always be together, you'll always be ready to go!
