The combi-squeegee scrubber is different in that it uses microfiber instead of a sponge like other one’s I’ve used to clean. The microfiber material is better for cleaning windows which tend to have a lot of small dust and soot particles. Its best to let the water and soap or Windex do the work with the microfiber holding the grime and leaving the glass clean. The soft cover is held on the handle with Velcro which can be removed and cleaned as needed. The squeegee has a rubber strip on the other end which removes any excess water from the glass left behind from cleaning. The squeegee is solidly built with tough plastic and doesn’t flex. It fits onto a regular broom sized extension pole for getting at windows higher up. It also has a hole through the handle for hanging on a hook, too. I’ve found washing windows much easier with a squeegee and this one gets it done quicker and better with its microfiber cloth washer.
