All Black Series products have been optimized and are offered in premium quality. The ErgoTec window squeegee has been equipped with the exclusive action rail. The power squeegee rubber is suitable for year-round use and has particularly good sliding properties and durability. The ErgoTec washer also gets an improved microfibre cover. The Power microfibre cover offers 20% greater water absorption than conventional microfibre covers.

This makes the glass cleaning tool even more economical to use. The same applies to the UNGER Black Series Power Liquid. The professional window cleaning soap features a new formula. The Power Formula is particularly powerful and ensures shiny, streak-free results. All individual products are also available in the exclusive Limited Edition Black Series window cleaning set, including a practical 18-litre bucket in exclusive black and with a special logo.
