Application questions

Which floor coverings can be cleaned with the floor cleaner?

Kärcher floor cleaners can be used on all hard floors, be they wood, stone or plastic. The rollers do not cause any damage such as scratches on the surfaces. Do not hold the device still in one spot; instead, always keep it moving.

How can I get better cleaning results?

To achieve good cleaning results with the floor cleaner, please note the following:

Wash the rollers in a washing machine at 60 °C before first use and once dirty.
If the rollers are too dry, you can wet them by activating Boost mode. Move the device back and forth until the rollers are sufficiently wetted.
Clean the floor multiple times with the floor cleaner without using detergent. This removes detergent residue from the floor.
Only use Kärcher detergent and make sure the correct dosage is used. Observe the recommended dosage on the detergent bottle. Using too much or not enough detergent can lead to poor cleaning results.
Run the device’s self-cleaning function.
Clean the hair combs regularly.

Wash the rollers in a washing machine at 60 °C (important: do not use fabric softener)Always use fresh water and do not leave water to stand in the tank after you have finished cleaningRinse the dirty water tank and fresh water tank thoroughly after each useClean the inlets and filters regularly, as described in the operating instructionsResidues of old cleaning detergents that are loosened from the floor during cleaning can also produce unpleasant odours

Troubleshooting

What should I do if the floor cleaner rattles loudly when I switch it on?

If the floor cleaner rattles loudly when switched on, it is possible that the rollers are too dry or have become deformed.

If the rollers are too dry, activate boost mode (only on the FC 8 and FC 7) and move the device back and forth until the rollers are sufficiently wetted. Alternatively, you can wet the rollers under the tap.

To prevent the rollers from becoming deformed, always store the device on the parking station provided and never store it directly on the floor.

What should I do if the floor cleaner won't switch on any more?

What should I do if the floor cleaner switches off and the LED error indication (“Battery” display) flashes?

Why does the floor cleaner switch off by itself?

As soon as the dirty water tank on the FC 7 exceeds a volume of 200 millilitres, the automatic device switch-off function is activated.

Using detergents from other manufacturers or using too much detergent can cause an excess of foam to develop and causes the device to shut down automatically before the 200 millilitres is reached. This is why we recommend that you use only Kärcher detergents and pay close attention to the correct dosage.

What should I do if the rollers are too dry?

If the rollers are too dry, please test the following: Run the device without the rollers fitted. The dirty water tank must be fitted and the fresh water tank must be filled. If four drops of water are left on the floor, the wetting function is working. We recommend wetting the rollers under the tap before inserting them. Alternatively, you can wet the rollers by activating boost mode. Move the device back and forth until the rollers are sufficiently wetted. If four drops of water do not appear on the floor, it may be because the fresh water filter is dirty. If this is the case, remove the fresh water tank and pull out the filter below it. Clean the fresh water filter under running water and then reinsert it.

This fault can also occur if the fresh water nozzles (see image) are blocked. Clean the nozzles with a cloth or a soft brush.

If the fault persists, please contact one of our service partners or send us your device for repair.

What action is needed if the "Dirty water tank full” warning appears, even though the tank is not full?

What action is needed when the “Fresh water tank empty” warning appears, even though the tank is full?

If the "Fresh water tank empty" error message appears even though the fresh water tank has been filled, this may be because deposits of detergent are covering the contact surfaces of the sensor. If this happens, remove the fresh water tank and the foam filter beneath it and use a cotton bud to clean the contact surface of the fresh water sensor. The contact surface can be found in the water inlet hole.

What should I do if the floor cleaner won't pick up dirt?

If your floor cleaner won't pick up dirt, take the following steps:

Fill the fresh water tank and insert it into the device, ensuring it is securely in place.Insert the dirty water tank correctly, so that it audibly clicks into place. Also check whether the cover of the dirty water tank is correctly in place (locking tab must slot into the corresponding recess).Insert the hair filters and rollers correctly into the device. The rollers must be screwed into the roller holder as tightly as possible. Clean the rollers when they are dirty and replace them when they are worn.Wet the rollers by activating the boost function (FC 7, FC 8) or under the tap. Move the device back and forth until the rollers are sufficiently wetted.Clean the fresh water filter. To do this, remove the fresh water tank and the fresh water filter and clean the filter under running water.

What should I do if the floor cleaner gets stuck in crevices?

The Kärcher floor cleaners are designed to wipe floors clean (no suction fan) and are perfectly suited for floors with a maximum height difference of 1 millimetre. Small 1-millimetre feet on the dirty water tank ensure the correct distance is maintained between the movable sweeping rim and the floor. This is necessary to ensure that the floor cleaner delivers a perfect mopping function while at the same time picking up coarse dirt (2-in-1). On very uneven tiled floors with gaps of more than 1 millimetre, this can cause problems as the movable sweeping rim can get caught and consequently damaged.

It is also possible that the studs on the underside of the dirty water tank have become damaged or worn. If this is the case, please contact the authorised customer service team.
