Which carbon brushes to use for the Kärcher A 2204?

Accepted Answer

The Kärcher A 2204 is equipped with an electric motor whose carbon brushes are wear parts that gradually wear out over time. When the device starts to lose suction power or makes abnormal noise, it is often a sign of brush wear.

Question 3

How to clean the filter of the Kärcher MV 5 Premium vacuum cleaner?

Accepted Answer

The filter is a key component of your Kärcher MV 5 Premium vacuum cleaner. Here’s how to clean it properly:

Regular filter cleaning

Turn off the vacuum cleaner and unplug it before any intervention.
Access the filter by opening the compartment designed for this purpose on the device.
Gently tap the filter over a trash can to remove accumulated dust. You can also use the provided brush attachment to clean the folds of the filter.
For a more thorough cleaning, run the filter under warm running water and let it dry completely before reinserting it (at least 24 hours).
Never use hot water or chemicals that could damage the filter material.

Cleaning frequency

Clean the filter every 2 to 4 weeks depending on your usage. A clogged filter reduces suction power and overloads the motor.

Filter replacement

If the filter is torn, cracked, or does not become clean even after washing, it must be replaced. Check for compatible replacement parts for your model.

Question 4

How to activate the suction system and the spray field of the Kärcher SE 5.100 Plus?

Accepted Answer

On the Kärcher SE 5.100 Plus, the suction system and the spray system are two independent functions. Here’s how to activate them:

Activating the suction (vacuum)

Plug the device into an electrical outlet
Press the suction button - the suction motor should start
Completely close the auxiliary flap on the handle to optimize suction power

Activating the spray (pump)

Press the spray button
Pull the lever on the handle to start the water jet

If nothing works

First, check these points:

The device is properly plugged in and powered
The dirty water tank is not full - empty it if necessary
The hoses are not clogged - check the airflow by placing your hand at the suction inlet
The clean water and detergent tanks are filled (if you are using the spray function)

If the problem persists after these checks, one of the two functions may be defective - test them separately to identify which one is causing the issue.

Question 5

How to replace the cartridge filter of the Kärcher A 2204?

Accepted Answer

When to replace the filter?

Replace the cartridge filter when:

It is heavily soiled or damaged
Suction decreases despite cleaning the filter
You notice visible signs of wear

Replacement steps

Turn off the vacuum cleaner and unplug it from the electrical outlet
Access the filter (usually located in the upper part of the device)
Carefully remove the old cartridge filter
Install the new filter ensuring it is correctly positioned and securely fastened
Close the access to the filter

Tip: Check the label on your old filter for the exact reference of the compatible replacement filter for your Kärcher A 2204. You can also contact Kärcher customer service to obtain the appropriate replacement part.

Question 6

How to properly secure the battery in my Kärcher T 10/1 Bp Adv?

Accepted Answer

If the battery does not click into place correctly in the Kärcher T 10/1 Bp Adv, here’s how to proceed:

Steps to secure the battery

Align the battery correctly - The battery connectors should be oriented towards the contact pins of the battery compartment
Insert firmly - Slide the battery into the compartment until it stops, applying moderate but firm pressure
Wait for the click - An audible/perceptible click indicates that the battery is securely locked in place
Check stability - The battery should not move or wobble once locked in

If the battery does not click in

Check that the connectors and pins are not dirty or damaged - clean lightly if necessary
Make sure to press with sufficient force (there may be resistance before the final click)
Check that the battery and compartment are not slightly misaligned - a small offset can prevent locking
If the problem persists, the battery or compartment may be damaged and require replacement

Question 7

The tank is full but the robot keeps indicating that it needs to be filled

Accepted Answer

If the water tank of the Kärcher RCW 4 is filled but the device continues to indicate that you need to fill it, the problem usually lies with the water level sensor.

Troubleshooting Steps:

Completely turn off the device and remove it from the window or cleaning surface
Open the water tank and ensure it is truly filled to the recommended fill line
Check that the sensor contacts around the tank or cap are not wet, dirty, or blocked by limescale
Gently clean this area with a dry cloth
Close the tank properly until you hear a click
Unplug the device for 30 seconds, then plug it back in to reset the electronic systems
Restart the robot

If the fill signal persists despite a full tank and clean contacts, the water level sensor is faulty. This part requires professional repair or replacement. Contact Kärcher customer service in your area or your retailer.

Question 8

Why won't my Kärcher RCW 2 start?

Accepted Answer

If your Kärcher RCW 2 won't start, here are the points to check in order:

1. Check the power supply

Ensure that the power cable is properly connected to the device and the wall outlet
Inspect the cable and plug for any visible damage before each use
If the cable is damaged, do not use it and contact Kärcher service

2. Check the robot's adhesion to the glass

Place the device on a clean glass surface (e.g., a window or pane)
The RCW 2 needs a watertight adhesion to the glass to create the vacuum necessary for its operation
If the device does not stick properly to the surface, it will not be able to start
Clean the glass surface and ensure it is dry and smooth

3. Check the battery

If the LED indicator is flashing red, it indicates a low battery
Allow the device to charge for at least one hour before use
Wait for the indicator to turn green before restarting

If the problem persists despite these checks, the Kärcher RCW 2 may have an internal malfunction. Contact Kärcher customer service for professional assistance.
