The Best Window Vacuum Cleaner: Our Choices
Buying and evaluation criteria for window vacuums
In the following sections you can read about the options available and find out which of them is particularly important for you.
Not all window vacuums are the same. Most models belong to the category of 2-in-1 devices, they combine a squeegee and a suction function. Before use, the windows are moistened or treated with glass cleaner. Often a spray bottle with integrated microfibre cloth comes with the device, so you don’t have to buy anything extra.
3-in-1 models combine three functions: Cleaning, polishing and vacuuming. This saves you even more time. Most of these devices have two tanks, one for the mop water and one for the dirty water. Of course, you have to fill the fresh tank before each use and refill it depending on the tank volume.
The window vacuuming robots are the least work, because they are simply attached to the desired surface. The devices can be controlled by remote control or app. Here you don’t have to lift for a long time. This is not only convenient, but can also be helpful for people with physical limitations.
Most devices come with the most important accessories. Microfibre cloths, spray bottle or attachments do not have to be purchased additionally at the beginning. Depending on the room height, it makes sense to extend the vacuum with a telescopic handle. This extension can be purchased cheaply, but is sometimes already included.
The squeegee lips and microfibre cloths are usually replaceable. So you can wash them or buy new ones when they are worn out. We strongly recommend this, because even the best window vacuum loses its efficiency as soon as it gets dirty or abrasion forms on the squeegee.
Battery life varies from unit to unit. There are also a few models that work with a mains adapter. Depending on the size of the surface, a battery with a low runtime or a battery with a particularly long application time can be useful here. The runtime of the individual devices varies from 20 to 100 minutes.
Depending on the device, the battery lasts from 20 to 100 minutes. The charging time is 2 hours on average.
The charging time is also relevant for many people. Especially in commercial areas or large houses, the vacuum cleaner should be up and running again quickly. For most devices, you should plan on a charging time of about two hours. Some units have an emergency battery, but this is not the norm.
The weight of the individual window vacuum cleaners depends a lot on the type of device. While vacuum robots are significantly heavier overall, 2- or 3-in-1 models are usually in the range of 0.6 to 1.5 kilograms. Depending on physical condition, desired cleaning time and surface size, any of these forms can be useful.
If you are still unsure, you can read what we have summarised for you under Handling. You should also bear in mind that accessories can make a lot of things much easier. A telescopic handle can make a big difference. We have also written a subsection on possible equipment.
There are vacuum cleaners that weigh less than 0.6 kilograms. Although the heavier devices are usually easy to hold, a lighter product can be much more comfortable, depending on the individual’s constitution and preferences.
Area of application
A window vacuum cleaner can be used for more than just windows. Glass surfaces such as table tops, doors, shower walls or display cabinets can also be cleaned.
Many models are also suitable for tiles or other surfaces. Sometimes certain attachments are needed for this, so that you can also clean joints and narrow corners, for example.
By preventing droplets, you no longer need to worry about your wooden floor or carpet. The vacuum dries the windows without leaving any marks. You can find more details about the function in the guide below or here under Handling.
The volume varies greatly from one machine to another. If you want to clean in offices or classrooms during the day, you should check how loud the device is before you buy it. There are often various videos on YouTube about how to use it. There you can listen to whether the noise level is acceptable for you.
Many device manufacturers explicitly point out a particularly quiet suction function in their product descriptions, so a good selection should not really be a problem.
Decision: What types of window vacuum cleaners are there and which is the right one for you?
Window vacuums all work in a similar way: they suck the wiping water from the glass surface without leaving streaks. However, they differ in the way they are handled. Depending on the model, battery life or suitable surfaces also vary. There are different types of devices:
|type of device||advantages||disadvantages|
|combi-solutions|| at least 2 functions in one device,
|usually separate wiper|
|Window vacuuming robot||controlled by app or remote control, time saving|| partly high noise pollution,
Each of the options has its advantages and disadvantages, so you should make your decision based on your intended use. Price, function and effect should be in reasonable proportion. We present the individual forms in detail and summarise the positive and negative aspects for you.
Guide: Frequently asked questions about window vacuum cleaners answered in detail
What is a window vacuum cleaner?
There are 2- and 3-in-1 solutions as well as vacuum robots. At the very least, they include a squeegee and suction function: you save polishing. 3-in-1 devices can also mop. Robot vacuum cleaners usually belong to the 3-in-1 solutions. They can be controlled by remote control or app.
Who is a window vacuum cleaner suitable for?
For people with physical disabilities, a robot vacuum cleaner is particularly suitable, because it only needs to be attached to the window for a short time and can then be controlled by an app or remote control without any further force. Particularly for older people, vacuum robots are a good help in maintaining independence.
A window vacuum cleaner saves at least one work step. The exact handling differs depending on the type of device.
What alternatives are there to a window vacuum cleaner?
|Window vacuum cleaner alternatives||Advantages||Disadvantages|
|Steam cleaner||You don’t need any cleaning agent because the device only works with water. Even stubborn dirt can be removed||Only for window cleaning it is not absolutely necessary to buy a steam cleaner, because a normal window vacuum cleaner also works very well here.|
|Cleaning by hand||Cleaning by hand does not require any financial investment. Cleaning cloths, squeegees and cleaner are usually available at home. For small surfaces such as bathroom mirrors, no device is necessary||The cleaning process takes longer. The individual work steps take time and are physically demanding, especially for people with physical disabilities and/or in houses with particularly large glass surfaces.|
In the following, we present the alternatives in more detail and explain why we ultimately recommend the window vacuum cleaner.
Cleaning by hand
Most people follow this or a similar sequence:
- Removing coarse dirt from windows
- Clean the windows with water/cleaner
- Remove the water with a squeegee
- Polish with a microfibre cloth
In principle, a window vacuum cleaner does nothing else, but it is much faster than we humans because it combines at least two steps. As a reminder: 2-in-1 models combine the squeegee and polishing functions, while 3-in-1 models can also wipe.
Cleaning windows with a steam cleaner
The term steam cleaner is also used by some suppliers as a synonym for window vacuum cleaner. All-round steam cleaners are actually intended more for floors, but can also be used for windows.
To generate steam, the appliance must heat up strongly, which takes time. It also has to cool down before refilling with water. It is therefore advisable to use units that have a reserve tank for refilling. For windows, a specific attachment usually has to be purchased for all-round appliances.
So you see: There are alternatives to the window vacuum cleaner. However, due to the time lost through heating, cooling, refilling, lack of accessories and subsequent cleaning, we recommend using a vacuum cleaner. This makes cleaning by hand easier, saves time and delivers the best results.
What does a window vacuum cost?
|Type of appliance||price range|
|3-in-1 window vacuum cleaner||50 to 250 €|
|2-in-1 window vacuum cleaner||30-70 €|
|Window vacuuming robot||120 to 450 €|
If you clean your windows once or twice a year, you don’t need an expensive robot vacuum cleaner. However, physically handicapped people can benefit from such devices. However, other solutions can also be found for the household, e.g. a cleaning assistant. You could get them a window vacuum cleaner.
Depending on the desired duration of use, the size of the surface and the nature of the surface, one model or the other is more suitable. When cleaning, people have their own wishes and priorities.
Be aware of yours and then see if the price is worth it or if you can do without one or the other function.
How do I prevent streaks and smears when using a window vacuum?
- Remove old cleaning agents
- When moistening, pay attention to uniformity
- do not apply too much pressure
- Clean the rubber lip regularly and replace it when worn out
- do not clean in bright sunlight (drying too quickly)
Streak-free cleaning is a challenge for many people, even without a device. Give yourself time to get used to the vacuum and follow the appropriate tips and manufacturer’s instructions. Your device should be of high quality, if you have saved money at the wrong end, you can consider buying a new one.
Is a window cleaner only suitable for glass or also for other surfaces, e.g. tiles?
Window vacuums are versatile.
When buying, always pay attention to the manufacturer’s specifications and think about what you want to use the device for in the end. One thing in advance: robotic vacuum cleaners often don’t find a foothold on tiles, so always pay attention to the exact mode of operation.
Which cleaning agent should you choose for using a window vacuum?
However, glass cleaners from other suppliers can also be used. It is important that these hardly foam or do not foam at all (risk of streaks!).
In addition to its own brand, the Kärcher company recommends a product with less than 10% alcohol concentrate. There are some cleaners that do not contain any alcohol at all. However, this is often not recommended, as alcohol can also dissolve oily and greasy residues.
Can the window cleaner also be used horizontally or upside down?
To be on the safe side, you should always read the description and inform yourself thoroughly before buying. Think about what you want to buy the device for and only then check what is on offer and whether you want to invest.
How long does a window vacuum cleaner need to be charged?
However, most good window vacuums manage with a charging time of 100-200 minutes. As a rough average, we have been able to determine a full charge within 2 hours.
What accessories are available for window vacuums?
- Spray bottle with integrated microfibre cloth
- Telescopic handle for extension
- Microfibre cloths and peel-off lips as replacements
- Attachments for narrow areas
- Attachments for or special surfaces (e.g. tiles)
- special glass and window cleaner
Depending on the scope of the device and individual planning, it may well be that you hardly need any spare parts. The microfibre cloths can be reused by washing and the squeegee lips are only replaced when worn.
Where can I find the operating instructions for my window vacuum cleaner?
Here you can sort by manufacturer and find your device. You can also start a Google search. Enter the name of the device and “operating instructions” in the search.
