Put to the test: Window vacuums, squeegees and cleaning robots

Swiss consumer magazine “Kassensturz” tested three systems that promise streak-free windows. Window vacs, squeegees and window cleaning robots were put to the test. Find out more about the test and the results and check out the best in test!

The test:

A jury tested each device on indoor and outdoor windows of different sizes and heights. They also tested windows that cannot be opened and are hard to reach. The acid test entailed the testers smearing the windows with chocolate cream before cleaning them.


When cleaning with a regular squeegee, the windows are washed down with a sponge first. Next, water-borne dirt is drawn off the glass with the rubber blade. All the tested devices were used in combination with a telescoping pole.

Window vacuums:

Window vacs draw off the dirty water from the window with a rubber blade and a vacuum function without leaving any drops on the window sill or floor.

Window cleaning robots

The Ecovacs robot lifts off dirt with a damp microfibre cloth. Similarly, the Sichler robot also clings to the window with a vacuum and cleans the glass with rotating cleaning pads.

Examined criteria:

  • Cleaning performance (40% weighting)
  • Handling (30% weighting)
  • Everyday use (10% weighting)
  • Cleaning the device (10% weighting)
  • Noise levels (5% weighting)

Saeco – italienische Kaffeetradition trifft auf Innovation

Discovering foreign countries and cultures and tasting coffee or other delicacies is what I enjoy most when I travel. My home is decorated with little gems I find in thrift shops and at flea markets. When I’m having one of my big DIY moments, my creativity is unleashed. Both the mountains and the seaside restore my inner balance. With a snowboard or surfboard under my feet, I’m happy.
