Cleaning made easy: Innovative tool transforms school’s exterior cleaning activity


Window washing was a major task for Tahatai Coast School's caretaker, taking up a significant amount of his time. The job required multiple tools and chemicals, and he was often drenched by the time he finished. 

The Unger Window Washing Solution saved on cost and reduced effort and time spent on window cleaning by 75%.


The Challenge

Greg Rieger, Caretaker for the two-story Tahatai Coast School in Papamoa, cleaned the school's exterior windows over two days every month. With a busy schedule and ever-increasing responsibilities, Greg needed a simple solution that reduced his effort and time on this particular job.

  • Greg was using multiple tools, such as a bucket, broom, blades, and chemicals, to clean, rinse, and protect the windows.

  • Ladders and scaffolding were required but can be a health and safety concern. Also, they take time to assemble, move around the buildings, take down, and store after each cleaning session.

  • The task became physically challenging every month, so Greg needed a simple solution with high-quality results.

The Solution

We suggested that Greg try the Unger Window Washing Solution kit for his school. The equipment only needed a connection to the water supply to do the cleaning.

  • The product not only cleans windows, but it also works exceptionally well on corrugated iron and weatherboard.

  • Ladders and scaffolding were now replaced with lightweight telescopic poles for higher spaces. This averted any health and safety risks and made cleaning easy.

  • No chemicals are required, and the kit only needs a small amount of water compared to the previous cleaning method.

  • It reduced two days of tiresome work to a few hours.

  • High-quality results meant reduced cleaning frequency from every month to once every three months.

"I wish I’d known about this product years ago. Previously I had been using bucket, broom, blades, and chemicals, also getting terribly wet. You don’t get wet with this Unger kit! Can’t say enough about the product and would have no hesitations in recommending it to other schools.”

  • Reduced health and safety risks due to easy connecting, use and storage of equipment. 

  • The no-noise unit causes no disruption to teaching because it's quieter.
