It is suitable for all Kärcher battery-powered Window Vacs. Extension kit for Window Vac - Part number: 2.633-144.0https://www.youtube.com/watch?v=irHRGen3D5E  

    • It depends on the size of the glass sections. For best results, the blade of the Kärcher Window Vacuum should be used flat against the glass. If the blade is raised due to the lead-lining then the vacuum may not clean as effectively. Kärchersuction nozzles are available in the sizes of 170mm (17cm) and 280mm (28cm).

    • To ensure the surface being cleaned is left spotless and streak-free, we recommend using the Kärcher Glass Cleaner Concentrate found on our website (Part number: 6.295-795.0). The Kärcher concentrate is designed for streak-free cleaning of all glass and mirror surfaces and will remove stubborn stains such as grease films, finger marks and emissions. If using an alternative brand of glass cleaner or detergent we cannot guarantee the same results. WINDOW TOO DRY: When using the machine ensure to apply a sufficient amount of cleaning solution to the window, this is will remove any friction between the rubber blades and the glass. If you feel any pulling on the rubber blades when driving down the glass or hear a screeching noise, this would indicate the window is too dry. At this point you should apply more solution to the windowPRESSING TOO HARD: Streaks can also be left if the window vac is being pressed too hard on the glass. Gently press the blades to the surface so that they are just touching and slowly glide down the area being cleaned. DIRTY BLADES: It is vital that the rubber blades are free of dirt and debris. You can check this by taking a cloth or kitchen towel and wiping it between the two rubber blades. The suction nozzle can also be removed and soaked in warm soapy water for 15 minutes, then thoroughly rinsed with clean water to clear any blockages.RESIDUAL PRODUCT: The window vac may also leave streaks if there is residue build up on the surface from previous cleaning, such as polish or other cleaning products. The streaks should gradually disappear with regular cleaning with the use of Kärcher Glass Cleaner Concentrate. We do not recommend the use of non Kärcher branded cleaning solutions as this may damage your product and void your warranty.

Ensure that the water tank is completely empty prior to using horizontally. Check that the neck section and the intake tube in the dirty water tank are not blocked with dirt, as this can force the water elsewhere, and can cause a leak. Give them a through clean, allow to dry and try the machine again.

    • Distilled/Deionised water can be used in the SC1, SC2, and SC3 models. However this cannot be used in SC4 + SC5. The SC4 and SC5 should use a combination of 50% distilled, 50% tap water. Using 100% distilled water with the SC4 and SC5 can cause too much water to be released into the boiler which causes the steamer to malfunction producing hot water instead of steam.

    • No, you should never use condensation water from a tumble dryer in your Steam Cleaner.

    • You can use a Kärcher Steam Cleaner to refresh the surface layer of your carpets or to spot clean. Our range of steam cleaner’s are not designed for deep cleaning carpets. For deep cleaning carpets please see our range of Spray Extraction carpet cleaners.

There's no need to spend hours scrubbing hobs and oven doors with chemicals, as the best way to clean these is with steam. 

    • Steam Cleaning is a a healthy choice for you and your family. Unlike cleaning detergents steam cleaners do not leave behind potential allergy-triggering residues on the cleaned surface. Allergy-sufferers can breathe easier, as the steam binds the dust, keeping allergens (house dust mites and their secretions) from being dispersed, this improves an indoor environment considerably.

    • Along with freshening up your clothes and fabrics, some of our steam cleaners can even be used for ironing using our specially designed Iron attachment (Part number: 2.863-208.0) which saves up to 50% of time compared to conventional ironing.

    • Kärcher steam cleaning doesn't require the use of harsh chemicals, which makes it ideal for cleaning and dusting household plastic plants. Gently clean by moistening the plants at a distance of 30 to 40 centimetres, and wipe off the dust with a cloth.

    • Cleaning with steam is cleaning without chemicals. The combination of steam power and temperature alone dislodges stubborn dirt and makes cleaning agents surplus to requirements. This conserves both water and the expense of cleaning agents.

    • With just tap water, a Kärchersteam cleaner effortlessly removes stubborn stains, Limescale and mould throughout the home. Nothing could be quicker or easier than cleaning with a Kärcher steam cleaner killing 99.99%* of bacteria as well as saving you time and water compared to using conventional methods.* Thorough cleaning with the Kärcher steam cleaner removes 99.99% of all common household bacteria from common household hard surfaces.

    • Steam cleaners work similarly to a pressure cooker. Water is heated in a closed boiler in the steam cleaner until it boils - this causes the formation of steam. This takes from thirty seconds, to eight minutes per litre of water depending on the machine. Once the water boils, the steam is released in measured quantities through the 'steam gun'. The higher the steam pressure, the quicker the release rate - and thus the dirt-dissolving performance.

    • Wet & Dry Vacuum Cleaners are perfect for sucking up dust, sludge, rubble, stones, shingle and liquids. For further information on the Wet & Dry Vacuum Cleaners, please click here.

    • Kärcher filters and filter bags are made from environment-friendly materials. They can therefore be disposed of with your normal household rubbish, provided that you have not sucked in substances that are not permitted to be thrown into household waste.

    • We would advise you to use the cartridge filter on your Kärcher Wet & Dry Vacuum at all times. Once finished please ensure the filter is completely dry before re-attaching.

    • If the cleaning power of the appliance deteriorates we recommend checking the following:  The accessories, suction hose or suction tubes are not clogged. If so, remove the obstruction using a stick or long object. If the filter bag is full, remove and install a new one. Check that the foam filter is not contaminated by cleaning it under running water. Ensure the cartridge filter is clean, by knocking off any dirt from the cartridge and rinsing under running water if necessary. If the filter is damaged, then this should be replaced.  

    • You must never vacuum hot ashes using your Vacuum Cleaner. Cold ashes should only be vacuumed when using a pre-filter (see image below) which can be purchased separately. (Part number: 2.863-139.0 / 2.863-161.0).

    • The cartridge filter on your Kärcher Wet & Dry Vacuum should be left on whilst being used for liquids. Once finished please ensure the filter is completely dry before re-attaching.

    • All Kärcher sledge steam cleaners will alert you by flashing red once the water tank is running low and needs re-filling to the 'Max' marking.  

    • The solid red light means there is no water in the steam boiler. Overheating protection of the pump was triggered, please:1. Turn off the appliance.2. Fill the water reservoir.3. Turn on the appliance.Another reason for the light to be solid red is that the water reservoir has not been inserted properly or is calcified, please:1. Remove the water reservoir and rinse.2.

    • Instructions for De-scaling your Kärcher Steam Cleaner.Step 1. Purchase a Kärcher de-scaling agent. Part Number 6.295-206.0 - RM descaler sticks 9x13 g.Step 2. Dissolve the descaling stick into 1 litre of warm water.Step 3. Pour the solution into the boiler and allow it to react for approximately 8 hours. Do not screw the safety lock onto the appliance while you are descaling.Step 4. Create a separate solution for the steam cap.Step 5. Clean the threads on the cap with a toothbrush and rub Vaseline around once clean.Step 6. Once the descaling is completed, empty the solution from the machine. A small amount of solution will remain inside the boiler. Rinse the boiler 2 or 3 times with clean, cold water to remove any residues of the descaler.

    • The boiler of your Steam Cleaner must be rinsed out after every 5 fills. This will reduce the build up of scale within the heating vessel. Fill the boiler with water and shake the cleaner vigorously. This will loosen any scale that has settled onto the bottom of the boiler vessel. Empty the machine by pouring out the liquid.

    • When you have finished using the machine make sure that you have released all remaining pressure from the hose and gun assembly. When the pressure has been released you can then unscrew the safety cap. Drain the machine of any remaining water in the boiler. Store the machine with the accessories removed, the boiler empty and the safety cap removed.

    • The safety cap may be difficult to remove due to the steam cleaner not being de-pressurised after use, or if there is a build-up of Limescale in the steam cap. For further information please see ‘How do I depressurise my Steam Cleaner?’  and ‘How do I descale my Steam Cleaner?’  

    • When in use, a pressure control valve inside the safety cap locks in place, restricting the removal of the cap. This is a safety feature of the machine, preventing the escape of steam. The safety lock cannot be opened as long as a slight pressure remains in the boiler. After use: 1. Turn off the machine and disconnect the mains plug from the socket. 2. Push the steam switch until steam discharge stops. The boiler of the appliance is now depressurised. 3. Remove the cap and store separately from the machine. **Please note that a residual amount of steam may be emitted when you open the safety lock. be careful when opening the safety lock, if the machine has been in continuous use for a long time the safety cap may be hot.

    • Check that the steam trigger isn't turned to the child-lock setting. This is indicated by an image of a lock on the trigger gun.

    • Your Kärcher Wet & Dry Vacuum may switch itself off due to the waste container being full. You should empty the container straight away and ensure the filter is not blocked.

    • When the steam cleaner is first turned on some water will be produced, while the attachments and accessories are still cold and this will condensate the initial steam produced. This may occur for a couple of minutes. Ensure the floor cloth isn’t attached to the floor tool until the machine is at full temperature and only steam is being produced, otherwise your cloth may become saturated with water.   For the SC1 and SC2 Steam cleaners, the water tank may be over full. Ensure that the tank is only 3/4 full, which allows steam to be generated in the boiler. Ensure that the machine has reached operating pressure, if not, wait until the light indicates that the machine is ready. Ensure that the controller is set to steam mode. Your steam cleaner may also need to be descled, for  more information please see ‘How do I descale my steam cleaner?’.

    • Your Pressure Washer should be stored in a frost-free environment. If being stored in a garage or shed we recommend ensuring that it is:1. Fully drained after use.2. The pressure washer should be raised off of the ground on a bench or table. 3. Wrap it in a blanket or place into a box. For information on how to drain your pressure washer, please see 'How do I drain my pressure washer after use?'

    • Whilst a static water source can pose potential threats such as legionnaire’s disease, the risk of this in the UK is very rare.  In order for the legionella bacteria to grow there needs to be a number of supporting elements, including high concentrations of rust, algae and organic particles.  It is these which supply the bacteria with a source of iron as well as nitrogen which is crucial in order for it to survive. In order for the bacteria to grow a water butt would need to have the above elements and be between 20-45°C; the optimum temperature for it to breed, for a sustained period.  As rust is very rare in water butts, the above supporting elements would have to be there, stagnating, in temperatures around 36°C for a sustained period.  In the UK the temperature varies most nights, as well as from season to season meaning that the temperature would not normally be sustained for a prolonged period of time.  All of these factors mean that the risk of catching Legionnaires' disease from a water butt is very low.  Ensuring you regularly clean and keep your water butt rust free will help reduce the risk of bacteria developing.
