The WRB 4000 Bio water treatment system for biological waste water purification treats the waste water from vehicle wash systems in a natural and environmentally friendly way. The system can process up to 4,000 litres of water an hour, thereby returning up to 98 per cent as clear and odour-neutral reclaim water into the circuit or directing it into the sewer system in compliance with the legal provisions. In doing so, it removes cleaning agents and drying aids reliably and without the use of flocculation agents and other chemicals.

Reliable recycling of the water is done in four steps: Firstly, undissolved floating materials and coarse solids are captured and deposited in the sludge trap. In the next basin there are micro-organisms that almost completely metabolise and remove the dissolved organic substances, e.g. oils, fats or surfactants, from the water. In the third step, the water goes to the above-ground post-sedimentation stage, in which residues like loosened mineral excess sludge are filtered out. The recycled water is finally collected in a tank and the next washes fed back.

Strongly contoured vehicles, demanding customers: The requirements of vehicle wash systems are becoming ever greater. If oil companies, service stations or car dealers want to offer their customers a premium service even at a high washing volume, powerful systems are required. Water is self-evidently saved with the CWB 3 Klean!Star iQ gantry car wash. Thanks to the standard water saving function, only 20 litres of fresh water is required for a vehicle wash. This conserves natural resources and reduces operating costs.

Kärcher high-pressure cleaners save up to 3,100 litres an hour, meaning they use about 80 per cent less water compared to cleaning with a water hose. They are distinguished by a great cleaning performance and cleaning efficiency with inherently lower consumption, which makes cleaning expeditious – consequently saving time, water and energy.

This is due to patented nozzle technology and customised adaptation to the performance of individual machines – you get a better result faster. In addition, most models can also be operated with reclaim water. For this, the machines simply suck the water from an available reservoir – for example from a water butt. This way, the user dispenses with the use of drinking water, thereby protecting the environment, and is also independent of the water supply.

Booster pumps enable the easy supply of the house and garden with well water or rainwater, e.g. with the BP Garden. The BP Home & Garden electronic booster pumps pump reclaim water automatically through the whole house. The BP Barrel barrel pump, the BP Cistern cistern pump and the BP Deep Well deep well pump work directly in the water.

The FC 7 Cordless floor cleaner removes all types of dry and wet daily contamination in a single step. There is therefore no need to vacuum before wiping the floor. This saves the machine up to 90 per cent of water when cleaning a 60 m² floor area, in comparison with a conventional mop with bucket.

The FC 7 Cordless works with four contrarotating cleaning rollers that are continuously moistened with fresh water and cleaning agent. The rollers reliably pick up all types of household dirt and wipe the floor both in the forward and reverse movement.

Numerous model series of Kärcher scrubber driers already have an eco!efficiency mode. With it, the brush speed and the suction power are reduced to a performance sufficient for lighter dirt. This allows convincing cleaning results with significantly lower consumption to be achieved. Up to 30 per cent of energy and 10 per cent of water and cleaning agent can currently be saved with the eco!efficiency mode.

With hot water under high pressure, comparable cleaning results are achieved with a significantly decreased use of water. Moreover, the eco!efficiency mode is used with hot water high-pressure cleaners. If it is active, the water temperature is set to 60 °C, as this temperature is completely sufficient for most cleaning tasks. The burners of the hot water high-pressure cleaners are especially efficient and environmentally friendly, as confirmed by the EUnited Cleaning association. Kärcher was the first manufacturer of cleaning equipment in the world to receive such a certification.

The certification includes several elements: The burners used must display an especially high effectiveness, while at the same time not allowing emissions of soot and carbon monoxide to exceed the very low limits. This combination leads to particularly environmentally friendly machines that not only release few harmful substances, but simultaneously make operating costs low due to their low consumption. The industry association EUnited Cleaning is the leading provider of floor cleaning machines and high-pressure cleaners for professional use.

With 40 per cent lower power input, the eco!efficiency dry vacuum cleaners achieve 98 per cent of the suction power of the basic machine, which is more than sufficient for daily maintenance cleaning. At the same time, the suction of eco!efficiency machines is nice and quiet, and can be measured and felt at only half the volume. With cordless machines, it also extends the working life while simultaneously offering a strong cleaning performance.

Kärcher water dispensers significantly reduce the energy expenditure for the provision of filtered, cooled or carbonated water compared with conventional drinking solutions. The standby mode of the advanced machines allows the operating time of every Kärcher water dispenser to be individually adjusted, so that the machine is only operated with minimum energy (< 0.5 watts) on days it is not used, for instance at the weekend. Upon request, ECO mode can also be activated. In this mode, water dispensers heat up water, for example, bit by bit just at the press of a button and do not keep it permanently hot. Cold water becomes less cool if not used for a very long time, with less energy likewise being consumed for provisioning. Energy consumption is reduced in this way.

In addition, grid-bound water dispensers significantly reduce CO₂ emissions, as the water is not transported laboriously for many kilometres in a lorry. In standard application, the Kärcher WPD models release about 80 per cent less carbon dioxide compared with gallon systems. Compared with bottled water, it is even about 90 per cent less. A further advantage compared with bottled water is potentially dispensing with disposable plastic bottles.

The Kärcher Battery Power exchangeable battery is suitable for use in numerous 18 V battery platform machines. Thanks to Real Time Technology and LC display, the remaining life, remaining charging time and charging state – depending on the machine used – are always on display.

In the home environment, battery-powered machines are not in use daily. For example, garden tools are practically never used in winter. Storage mode guarantees a long cell lifetime if they are lying unused in the garage over a longer period. A charging state of 70 per cent is ideal for longer storage. If the battery pack is stored at over 70 per cent and not used for more than 21 days, a mode is automatically activated that partially discharges it to 70 per cent.

The best way to avoid exhaust fumes and emissions is to not let them be produced in the first place – like with use of our outdoor power equipment products. With high 36 V performance and endurance, no compromises have to be made when working with leaf blowers, hedge trimmers, etc. At the same time, users work quietly, emission-free and ergonomically.

Our Battery Power platform enables emission-free and flexible work around the house. Without any annoying cord or loud combustion engine, battery-powered garden and cleaning machines offer maximum freedom of movement and are ready for use in an instant. Thanks to the Kärcher Real Time Technology, the battery state can be checked at any time at a glance. The integrated LC display shows how many minutes of work can still be carried out with the current battery. And, on the battery charger, the battery display shows how long is left for the battery to charge – to the exact minute.

Many tasks on construction sites, in workshops or on the production line for industry produce large amounts of dust. Various precautions must be taken in order to comply with work protection regulations and keep the impact on health as low as possible. The aim is to keep work environments largely dust-free. Types of dust that also contain constituents such as pollen, quartz, mould, viruses or even asbestos are especially problematic.

Safety vacuum cleaners are designed so that they reliably absorb and dispose of such particles. Filters are designed to collect fine dust particles and prevent them from being released back into the surrounding air. When dealing with large amounts of dust, there is a risk of this clogging up the filter and considerably reducing the suction power. Safety vacuum cleaners are therefore equipped with systems for filter cleaning.

Fully automated functions for filter cleaning allow the absorption of large quantities of fine dust without interrupting work or losing suction power. Kärcher also uses the further developed Tact system in its safety vacuum cleaners. Here, a sudden switch of the air flow cleans the filter automatically.

Noise emissions too are emissions that should be reduced. Therefore, we optimise our machines both in terms of their volume and the type of noise. The K 2 Silent high-pressure cleaner is 10 dB(A) quieter than the previous model. A person will perceive this reduction as a halving of the volume. In addition, the frequency spectrum has been influenced so that the remaining noise is felt as significantly more pleasant. We have achieved this by using innovative plastics, such as special polyurethane damping materials. These effectively disconnect the pump from the housing. In addition, we use sound-absorbing foam mats made of melamine resin.

Kärcher was one of the first companies to use the "Technyl® 4earth® technology" from the manufacturer Domo in series production for the end consumer market. The recycled material used is extracted from fabric in recycled airbags and material left over from their production process. That guarantees both a consistent material quality and security of supply. In addition, CO₂ emissions, water consumption and the use of non-renewable energies can be significantly reduced.

The polyamide used is reinforced with 30 per cent fibreglass. As the spray lances of the Kärcher high-pressure cleaners must withstand an exceptionally high pressure during use and also have to be hard-wearing against environmental influences and cleaning agents. What is also special is that the recycled material displays no loss of properties compared with the raw material.

We use recycled material in our Home & Garden range whenever possible. For example, for the lower housing parts of our SC range steam cleaners. The shape of the material remains stable across a wide range of temperatures, which makes it the ideal material for steam cleaners and has no disadvantage compared to new plastic.

Under the name eco!perform, Kärcher offers environmentally friendly cleaning agents for professional use. The range includes a complete line for building cleaning and products for vehicle washes, which have been awarded international environmental certificates such as the EU Ecolabel or the Nordic Swan Ecolabel.

In order to satisfy the strict requirements, the eco!perform concentrates satisfy the issue of sustainability in a number of ways. Firstly, Kärcher totally dispenses with materials that endanger the environment and people's health during manufacture. So only fully degradable surfactants are used, and phosphates, microplastics and halogenated hydrocarbons that are hazardous to health are avoided. In addition, the fragrances and dyes used meet the standards of the international ecological certification. The containers also comply with the environmental requirements regarding weight, composition and recycling.

The eco!perform products are also particularly sustainable in terms of dosing. Small amounts of the agent are enough to achieve the best possible cleaning result. Owing to their high effectiveness they are very efficient, and up to 50 per cent less agent than comparable products can be measured out.

Destroy weeds on paths and open spaces totally without chemicals – the use of hot water allows this. This way, dandelions, thistles, etc. can be removed totally without herbicides. The principle of thermal weed control is based on a basic biochemical rule – most proteins denature from a temperature of about 42 °C. This means that the proteins change, break up and are no longer able to fulfil their functions.

The heat required for this can be generated and converted in different ways – as a direct flame or indirectly via thermal radiation, as hot water or steam. Of these, hot water is the only method without chemicals that also sustainably reaches the roots and consequently curbs fast regrowth. Hot water high-pressure cleaners can offer a consistent water temperature of up to 98 °C, which is just under the steam limit and is therefore ideal. Even if the roots are not immediately completely destroyed, the weed is further weakened with each application of hot water. If it is regularly applied right from the beginning, regrowth is impeded and the application frequency will significantly decrease as early as the second year. As a rule of thumb, three to four treatments a year are sufficient.

Floor coverings were polished using crystallisation for many years. This is often still true even today. The user applies an acid to the floor covering here, which they then work in mechanically in order to etch the surface. Then the floor is polished – a laborious procedure that produces a great deal of dust, and which on account of the acid is not without danger. Meanwhile, instead of this process, single-disc machines or scrubber driers are now operating with diamond abrasive pads, which can be used on nearly all stone surfaces and bring back the shine to high-gloss surfaces in a single work step.

Totally without chemicals, thanks to the preset steam flow control, the SC 3 Upright EasyFix steam mop is ideally suited to clean all sealed hard floors – even wood. With thorough cleaning, the machine actually eliminates up to 99.999 per cent of enveloped viruses*, such as coronavirus or influenza viruses, and 99.99 per cent of typical household bacteria**. When it comes to thorough cleaning, the SC 3 Upright EasyFix Premium is considerably superior to conventional methods such as using a mop, thanks to the combination of the EasyFix floor nozzle with the hook-and-loop system and high-quality microfibre cloths. So the user do not have to come into contact with dirt when changing the cloth.

_{*When spot cleaning using the Kärcher steam cleaner, i.e. a steaming duration of 30 seconds at the maximum steam stage with direct contact with the surface to be cleaned, 99.999 per cent of enveloped viruses such as coronaviruses and influenza viruses (except the hepatitis B virus) can be removed from typical smooth and hard household surfaces (test germs: Modified Vaccinia Ankara virus).}

_{**When cleaning at a cleaning speed of 30 cm/s at the maximum steam stage and with direct contact with the surface to be cleaned, 99.99 per cent of all household bacteria on smooth, hard household surfaces are killed (test germs: Enterococcus hirae).}
