Scrubber machines have been used to clean hard and flexible floor surfaces in indoor areas since the 1950s. The tried and proven single-disc technology guarantees good results, only rarely does the roller/brush technology have any effect. All this changed in 1986, when the cleaning specialist Kärcher, until then known mainly for high-pressure and suction technology, brought a walk-behind machine with roller brushes onto the market. The company responded to a need that was only regional: While Asia, southern Europe and the USA often sees the installation of smooth floors, which are effectively cleaned by means of disc technology, more structured floors such as grouted tiles or natural stone with rougher surfaces are found in northern and central Europe. Regardless of the floor condition, heavily soiled included, roller brushes achieve an improved scrubbing and polishing performance and hence a more consistent result. The background: Roller brushes work with a high contact pressure, since the contact surface on the floor is less, and faster revolutions are possible than with disc brushes.

Rising cost pressure and higher customer expectations – the floor cleaning sector too had to overcome this challenge, hence the call for a greater variant diversity along with the desire for low investment costs. And so since the start of 2000, the platform strategy involving the idea of using as few new parts as possible and hence significantly reducing development and production costs, proved its worth in the development of new models. A degree of individualisation, which could not be achieved efficiently and cost-effectively by introducing various individual models, is also possible. Many aspects of the latest machines can be freely configured by the user, depending on floor condition, surface and degree of soiling.

Tennant releases its T300 Walk-Behind scrubber. Among the innovations available for the first time on a Tennant walk-behind scrubber are LCD Pro-Panel™ controls and ec-H2O NanoClean® Technology. ec-H2O NanoClean Technology offers the same great benefits of the first generation and now cleans better by cleaning more soils in more applications.**
