If your Karcher window vac is having some issues, there are quick fixes that can be employed to bring the situation back to normal. In times past, you may need to buy a replacement part or a new machine if there is a fault with your window vacuum.

But in today’s world, you can fix some major problems without spending a dime so that you will be able to enjoy your machine. Let us look at some of these common problems and their solutions before you start shouting for help.

Battery problem: If your battery is not running, the battery may be bad or the charger is not working. It is also important for you to ensure that the battery is properly plugged to the wall so that the right current is flowing.

Also, you must ensure the points make the right contacts and this will ensure that the right terminals match each other. You can try to replace the battery if you have tried all the suggested approaches and if the problem persists, you can replace the charger.

Battery Corrosion: Battery corrosion is usually caused by water that leaked to the battery chamber leading to the death of the battery. There are many ways of preventing corrosion. You must ensure that you always keep your vac in a dry place.

Also, you should be careful with your angle of operation when working with the vac. Ideally, you should avoid using the vac on its side very often or upside down so that water will be prevented from entering the battery chamber.

Battery Life: The battery life of most Karcher vacs is between 20 and 35 minutes. However, if you discover a shorter battery against the specified value after purchase, you can negotiate for a replacement of the battery.

You need to note that batteries lose their runtime as times roll by due to frequent recharge. Usually, this loss of runtime should manifest after about a year of use depending on the frequency of use.

Battery Flashing Light: When you see a flashing light, it means your machine is low on battery. In a situation like this, you need to recharge your battery. However, in some other instances, you may see a flashing green or red lights which may indicate a fault.

At times, the low battery light may stay on even when the battery is dead. The light may even stay while charging and eventually, it may work for just a few minutes. You should replace your battery or better still, go for a full product replacement. If your warranty has not expired, a replacement will not be difficult for you.

Streaky Finish: If you see a streaky finish after cleaning your window, you may be found wanting in terms of following cleaning instructions. You need to clean your window properly following the instructions in your manual so that you will be able to get a perfect result.

Ideally, you should try to clean from top to bottom and this will go a long way in eliminating streaks after cleaning. You should take your time to go through the user manual properly and this will help you to understand the best way to make use of the machine.

On / Off Switch: If you are having issues with your on/off switch, it may be clogged with dirt. Usually, you can try to clean the cavity of the switch so that unwanted dirt can be eliminated.

If the problem persists and your machine is still under warranty, you can go for a replacement. If not, you can get a technician that will help you to fix the problem.

Noisy Motor: Most Karcher window vacs don’t make too much noise. However, if your machine is making too much noise, you can get a replacement if your warranty has not expired.

Alternatively, you can use a headphone or play a piece of loud music as a source of distraction from the noise. Who says you can’t enjoy yourself while you clean your windows?

Tips and Tricks to Make Your Glass Sparkling Clean


Making your windows streak-free can be a great challenge, especially in today’s busy world. Your schedule is very tight and you don’t have enough cash to hire a professional cleaner. You are not alone.

Many times, a lot of us spend a lot of our precious time cleaning our windows only to be left with dirt thereafter. You need to use the correct methods and tools to clean your window so that you will be able to get the most satisfactory outcome. Here are some tips to help you get the best from your window cleaning without going through too much stress.

Let Your Cleaning Be From the Top to the Bottom: To achieve a streak-free cleaning, you should let your cleaning be done from top to bottom. Since the cleaning solution can drip, you should explore this situation by starting your washing from the top and moving the window vac down.

This will go a long way in ensuring that there is no drip on the surfaces you have cleaned. The result is a sparkling clean window that will be streak-free.

Wash Your Windows on a Cloudy Day: This may sound absurd but it works. When you clean on a sunny day, the cleaning solution will dry up quickly before wiping it away.

That is why you can fix your cleaning on a cloudy day so that you would have successfully wiped off the cleaning solution before it dries up. However, this does not mean you should not clean on a sunny day, but a cloudy day is better.

Make Use of a Squeegee: A first cloth wipe may not be enough to remove all the cleaning solution on your window. This may necessitate a second wipe which may leave streaks on it.

As a result of this, you can use a squeegee, especially a long-handled one, so that it will be easier for you to polish every section of your glass. You can also use the long squeegee to clean the doors and walls of your shower so that you will be able to get a sparkling finish.

Use Cotton Swabs for Corners: Window corners are very difficult to clean as some stubborn dirt will always stick there. You can use cotton swabs to clean the corners and this is not very difficult to do. You only need to make sure that the cotton swabs are properly prepared and their application to the corners should be strategic.

Experiment with an Old T-Shirt: You can save money by experimenting with your old t-shirts. They can clean your windows perfectly because they don’t have lint residue and this will prevent streaks from developing on your glass.

It is an environmentally-friendly way to clean your home and is also good for your pocket. There is nothing bad in experimenting, after all, you don’t have anything to lose. If you carry out this instruction properly, you will not only get a perfect outcome but a cost-effective approach to cleaning your window.

Use Homemade Window Cleaner: You can make your own solutions at home to clean your window so that you can protect your glass from unknown chemicals. In addition, you will also save some bucks which would have been used to buy chemicals.

Making your own glass cleaner is not so difficult, you only need to blend a cup of alcohol with water (1 cup) and vinegar (1 tablespoon). This combination can also be used to clean your hard tiles as well as other surfaces in your home. You will be amazed at the result you are going to get if you follow the instructions properly.

Make Use of Newspapers: You can experiment with newspapers to give your window a perfect wash. Instead of using towels or cloth, you can try newspapers even though they don’t hold up properly when wet.

You can use gloves to apply them if you want to protect your hands. Using newspapers to clean your window is not a bad idea and if you do it well, you are going to get a good result.

Don’t Use Cleaners Woodwork: The chemicals in some cleaning solutions can damage the wooden frames of your window. As a result of this, you should try as much as possible to prevent direct contact between these chemicals and the frames.

A cloth can be placed on the frame and you should not spray too much cleaning solution at once. Alternatively, you should apply from one section to another right from the top to the bottom. This will go a long way in ensuring a perfect outcome.
