The dosage is regulated electronically, and the mixing ratio is always ideal: if less water is supplied, then fewer chemicals are used. Floor covering (or floors) are thus cleaned gently and stay beautiful longer. In a sense, every cleaning cycle is an act of environmental protection.

Keeping things as compact as possible reduces material consumption and achieves the highest possible efficiency of the energy used. The tanks of columbus cleaning machines are one example: constructed using innovative double-wall technology, the solution tank encases the battery compartment, saving space and weight.

Low-friction gears require less energy to achieve the necessary power output for the brushes and the traction motor for optimal results.

Polyethylene can be ground into pellets and reused as a raw material for new tanks, and steel can be recycled such that it retains its original quality. The machines are equipped with electromechanical elements as far as possible. These mechanical components are easily recyclable; there are far fewer toxic electronic components than in large, centralised electronic control boards.

columbus brushes have extensive, textured bristles positioned over the entire surface area of the brush. This way, the bristles work over a larger area and also distribute the sparingly applied water absolutely evenly. In addition, the outer ring of bristles is particularly dense and always retains sufficient cleaning solution within the brush, even when using small quantities of water.
