You can use a steam cleaner with steam volume control (lowest level) to clean laminate or parquet flooring – provided it is not oiled or waxed! Use two cleaning cloths (= 4 layers) so that as little steam as possible comes into contact with the surface. Do not hold the nozzle in one place for a long time. Please make sure that no puddles form, as the residual moisture will then dry quickly and with streak-free results.

The steam cleaners can be used for many different cleaning tasks, for example, cleaning bathrooms, kitchens, floors, windows, shower cubicles, glass, taps, tiles, grouting, stove elements and glass ceramic hobs. Steam cleaners not only remove stubborn dirt, lime residue and grease deposits but also kills 99.99% of bacteria of household germs. 

The temperature of the steam at the nozzle is around 100°C and around 84°C on the object being cleaned.

Every steam cleaner comes with two steam pipes as standard. The pipe can be easily extended with an additional pipe.

Demineralised water removes minerals from the boiler and damages it as a result. We therefore recommend using tap water. Please make sure to descale the device regularly.

Check the power cord and fuse, as well as the thermostat and pressure switch. Top up the water. If the water shortage light does not go off, please consult one of our service partners or contact us directly.

If the safety lock is stuck or spins round, allow the station to cool down and, if necessary, release the pressure by pulling the steam lever on the steam hose until the lock opens. If the lock cannot be opened in a cold state, please consult one of our service partners or contact us directly.

Descale the machine. If the heater is damaged, please consult one of our service partners or contact us directly.

The water shortage thermostat may be defective. Please consult one of our service partners or contact us directly.

Switch the heating on, plug the steam iron in, check the switch on the steam iron and replace it if necessary. If the solenoid valve does not open, please consult one of our service partners or contact us directly.

Please consult one of our service partners or contact us directly.

Allow the ironing station to heat up fully, set the controller to steam stage and fill the water tank just up to ¾ full.

• Pour all of the detergent concentrate supplied (20 ml) into the spray bottle supplied and fill it up with water. 
• Depending on how dirty the windowpane is, you may have to clean it several times. The cleaning agent solution should not be allowed to dry on while you do this. 
• Hold the window vac so that that the squeegee is perpendicular to the windowpane and do not use too much pressure. 
• We also recommend that you clean the squeegee regularly, removing any dirt residues. The squeegee can be pulled out sideways. If the squeegee is worn, it should be replaced. 
• Spray the windowpane so that it is moist all over.

Make sure that the dirty water tank is not too full, particularly if you are using the device in a horizontal position or above your head.

Charge the battery if the operating display is off or if it is flashing slowly. If the display is flashing quickly, please consult one of our service partners or contact us directly.

Depending on the model, Kärcher water blasters for private use have a flow rate of between 230 and 600 l/h (around 3,500 litres of water flow through a garden hose every hour). Water blasters are therefore easy on your budget as well as the environment.

In a water blaster, an electrically powered pump raises the water pressure many times over to up to 150 bar. With this pressure, the water is conveyed through the high-pressure hose to a lance, where it is ejected as a sharp, concentrated jet from a nozzle, creating enormous cleaning power. If the spray gun is not activated, the pump will switch off automatically. A water blaster allows you to carry out your cleaning tasks even more quickly than with conventional methods while also using less water.

Yes, you should use a suction hose with filter for this. Attach the suction hose to the water infeed on the device. Insert the other end into the water butt. Connect the high-pressure hose to the device. Before switching on the device, remove the steel pipe from the spray gun. Press the lever on the spray gun so that this is open and switch the device on. This will allow the air inside the device to escape gently as the pressure washer starts to draw in the water. The device should not be any more than 0.5 m above the point of use.

• Simply spray the vehicle down with high pressure to remove coarse dirt. 
• The cleaning agent is applied gently onto the vehicle in low pressure. 
• You can also use a wash brush.

Kärcher cleaning agents are specially formulated for our devices. Your warranty will no longer be valid if you use cleaning agents other than those supplied by Kärcher.

T 350 surface cleaner can be used for all devices from classes 2 to 6. T 450 surface cleaner is only suitable for devices in classes K5 to K6.

• Connect the device to the water supply and turn on the tap.
• Remove the filter from the water inlet and clean it. 
• Switch the water blaster on without the steel pipe and allow it to run until there is no more air coming out of the spray gun. 
• Check whether you are using the right accessories. 
• If the pressure and suction valves are leaking and there is water coming out of the casing, or if the device is throbbing, please consult one of our service partners or contact us directly. 
• If the overflow valve is stuck, please consult one of our service partners or contact us directly.

• Clean the nozzle insert. 
• Check if you are using the right nozzle. 
• Check if there is enough water coming out.

• Check the power supply and mains fuse. 
• Check the main switch and spray gun. 
• For extension cables of 10 m or longer, the diameter must be at least 2.5 mm². 
• Completely unwind the cable drum.

In the following cases, please consult one of our service partners or contact us directly:

• The pressure switch or control pistons are stuck 
• The motor is overheating 
• The main switch is faulty 

Please consult one of our service partners or contact us directly.

• Fill up the cleaning agent container. 
• Rinse out the vacuum filter with fresh water and clean it. Once you have finished cleaning with cleaning agent, you should rinse the device out with fresh water to prevent the filter from clogging up. 
• Check the suction hose for damage. 
• Take the cleaning agent hose on the device and, using a thin object, push back the valve on the hose nipple so that it moves smoothly. 
• Start the flow and set to low pressure.

Check that the suction hose is inserted properly and that there are no defects. Check that the filter is in place and that it is not defective. Use a filter bag.

Replace the filter bag, clean the cartridge filter/flat pleated filter, nozzle, suction pipe and suction hose. Replace the seals if necessary.

The device switches itself off when the dirt receptacle is too full. If the filling level probe and casing are wet, this can cause a moisture path to form. Allow the device to dry out and clean the filling level probe.

Check the fuse and socket and check the cord and plug for any damage. If the power switch, carbon brush or power outlet are defective, please consult one of our service partners or contact us directly.
