Window Vacuum Buyers Guide

Window vacs have proved to be popular household appliances over the past few years and there is a good reason for this. These resourceful devices ease the burden of laborious glass cleaning. Let’s take a look at the factors to consider before you purchase a window vacuum-


Your budget will significantly impact the brand and type of model that you decide to buy. If you are on a tight budget then it’s likely that you will need to make some compromises. First, think about the important features that you need and those that you can live without.

There are a variety of decent, budget-friendly vacuums on the market, however, if you are after a premium appliance that offers longer battery running times, for example, you will need to pay slightly more. Window vacuums with a higher price tag will be equipped with additional functions and accessories that you might not find on cheaper models.


Running Time

If you intend to frequently clean multiple windows in one go then you want a device with a decent battery life to see you through longer tasks without the battery dying partway through window cleaning. Ideally, you want a device with a minimum battery running time of 25 minutes.

Most window vacuums are cordless and come with rechargeable batteries. Stick to our recommended products to ensure that your chosen product is equipped with high-quality Lithium-Ion rechargeable batteries.

You don’t want to be stuck with a cheap appliance that contains an inferior battery with short running times and shelf life. As you can see, the quality of the battery is a significant feature. It would be frustrating to get a battery that runs for just 15 minutes but takes 2-3 hours to charge.


Overall, you want the freedom to move between rooms and clean windows and mirrors with the freedom of a cordless machine, therefore, longer battery times are always the preferred choice. Before you buy a window vacuum you should consider the number of windows that you plan on cleaning and the size of your home.

Head Shape

The shape of the cleaner head is pivotal to the effectiveness of your new window vac. These units are supplied with heads that come in different shapes and sizes. Some models come with swappable heads which are a huge advantage.

If your household has different sized windows then you want to choose a unit that comes with multiple heads to help you tackle windows of any shape and measurement. You want a window vac with a cleaner head that can reach into small nooks and tight corners with relative ease.



It’s always nice when a manufacturer throws in some bonus extras to accompany your new appliance but you should be prudent as this is often used as a way to entice you into choosing one brand over the other. You don’t want to end up with an inferior product for the sake of a few extra spray bottles and sponges.

Take your time to consider what is included with a potential purchase and decide if it’s beneficial. Overall, the most important thing is the performance of the primary unit.


Cleaning windows requires plenty of movement, therefore, your chosen unit should provide you with the freedom to do this freely. The best rated window vacuums can be used at any angle and moved into any direction. Make sure you choose a model that provides a maximum amount of movement.

Consider the parts of your home that you’ll be using your window vac. Are your windows located in areas with limited space or corners that are difficult to reach? If this is the case, you want to invest in a model that steers into cramped spaces easily.


Choose a Reputable Brand

Searching for a window vac often involves looking through different manufacturers specifications and deciding which brand is best. There are plenty of brands trying to persuade you to choose their products but the best advice here is to stick with established manufacturers that have been around for many years.

Investing in a longstanding brand gives you the assurance of a long lasting high-quality product that will give you the reliability that can’t be found on cheap units. Household brands will back up their appliances with a robust guarantee and usually have a support team to help with any issues.

Factors to Consider Prior To Purchasing a Window Vac

Once you’ve looked through the specifications of potential appliances, you’ll be almost ready to make an informed decision. The hardest part is deciding the best-suited model from your shortlist. I’ve put together a few questions that you can think about to help you choose what’s best for you.-


What are your exact needs? Although a window vac is used for cleaning windows, each person will have individual requirements. What might be important for one person might not be necessary for someone else. Make sure you are aware of your criteria before buying. You should consider things like the amount of glass and windows in your home, have you got sliding glass doors or windows? What is the weather like in your area? How regularly do you want to clean your windows? These are some of the things to take into account.

Is the window vac cord-free? Most window vacs are cordless but it’s still possible to find corded models and both variants have their good points and bad. Cord-free cleaners allow the convenience to move through the house without a power cable imposing restrictions on how far you can go. The advantage of a corded model is that it provides unlimited power, therefore you never have to worry about stopping halfway through cleaning to recharge a flat battery.

Window Vacuum Weight- When it comes to window cleaning, a lightweight appliance is always better. You want to find the lightest model possible to ensure that there is no strain to the hand, wrists and arms whilst cleaning. Heavier machines are harder to use to clean big, tall windows. If you intend on cleaning large areas you want a window vac that weighs
1.1 kgs (2.4 Pounds) or less. Our recommended window cleaners meet these requirements.


How effective is it at cleaning? A decent window vac should be able to provide clear-view windows with relative ease. The cleaner head, squeegee and other accessories should all be designed to achieve excellent results whilst keeping streaks at bay. At the very least, your new window cleaner should be able to provide the above.

We’ve gone through the basic criteria of a window vacuum and some of the questions you should be asking yourself before you buy one, however, you might have some additional requirements that you would like to know about to make the best choice-

Window Vacuum Performance

The best window vacuum should ideally perform the tasks below without causing you to break a sweat:

Cleans small spaces and edges: As mentioned briefly earlier, the window vac should allow you to move the cleaner head in whatever direction you desire and be able to access areas that are difficult to reach. To do this, the machine should be equipped with a dynamic blade that works at any angle. Ideally, you want a model that comes with different sized exchangeable heads and a flexible neck to help clean awkward edges, hinges, lattice shutters and corners.


Is the Window Vac Compact? We’ve already touched on the importance of a lightweight machine, however, we also need to consider its size too. Compact units can be stored virtually anywhere that is convenient and within easy reach, such as under the kitchen sink or a close-by cupboard. The key to a great window vacuum is a portable and lightweight model that provides a comfortable user experience and helps to avoid back injury or strain.

Can it keep streaks away from glass? Streak-free cleaning is a prerequisite of any window vacuum, even the most basic model should be able to get rid of streaks easily. If your window vac is leaving streak marks after a cleaning session then it’s not performing properly. Make sure that the blades are cleaned after each session and the machine is equipped with all the correct accessories to produce spotless results.

Adaptable: On top of providing great cleaning performance, your window vacuum should also be able to clean other areas of the house. Most models can clean any type of smooth surface including mirrors, glass tables, marble surfaces and so on. If you split some water on the floor or dropped some crumbs, your new window vac should be able to pick this up. You can also clean your shower screen and restore it to an immaculate condition. In addition to this, the window vac can remove condensation from surfaces.

What sets apart a Window Vacuum from the competition?

A window vacuum that enables you to clean glass in next to no time is great, however, there are some ergonomic features that improve the cleaning experience and convenience depending on which brand you choose. Take note of the features below, found on high-performance units, that add to the appeal of a window vac:

Two-Stage Cleaning

High-end window vacs utilize a 2-stage cleaning system. The 1st stage involves the machine applying window cleaning fluid and water to the glass with an applicator. The integrated microfibre cloth then removes grime that would usually leave streaks if you tried to vacuum it immediately. When the grime is removed, the window vac goes into the 2nd stage, slowly move the machine across the glass to remove leftover dirt. The same process also draws water away from the glass and produces a gleaming surface.

Can the Water Tank be Cleaned Easily?

Some brands will come with a removable water tank whereas other models come with integrated self-cleaning tanks that get rid of dirt by simply pressing a button. Dirty water collects in the tank as you work through your windows and when it is at full capacity you just click a button, detach the tank and drain it out. Some tanks are even dishwasher- friendly to help maintain your gadget and keep it working at its best.


A good window vac should be accompanied with a variety of accessories to improve its versatility and use. As previously mentioned, wherever possible you should buy a model with different wiper blade sizes to ensure that it can clean both large and small spaces as well as tight corners. You always want the choice of a convenient option to simplify the job.


Some models are equipped with a wrist strap for safer use and better comfort. At first, I didn’t think that a wrist strap would make a difference but I was wrong, it gave me better control and grip over the machine.

LED Lights Are a Clever Feature

Premium window vacuums are fitted with onboard LED lights that will show you the remaining battery power. This will help you gauge how often the machine needs charging and if it has enough power to complete longer tasks. You don’t want to end up with a cordless device that cleans blindly and doesn’t indicate how much battery life is left. LED lights ensure that you don’t need to worry about the battery dying during cleaning. Double check the battery level before applying soap and water to the window and charge the unit if necessary.

Technology To Clean Edges Easier

Some brands have equipped their units with clever technology to assist with manoeuvring the blade edges to offer you with better handling of the machine and guiding it in the desired direction with precision. The result is easier access to corners that are normally difficult to reach to give your window pane a well-rounded clean from top to bottom.


To Conclude

Before you rush out and buy a window vac you need to separate the good ones from the bad. What should you look for? First and foremost, you need a unit with a decent battery operating time and shorter charging times. Look for machines with a minimum running time of 25 minutes.

The next thing you need to think about is the cleaner head shape and if it has been designed to reach the tight corners of window frames. If not, does the appliance come with extra accessories to handle awkward nooks?

The last thing you want to consider is your budget and if it can stretch to buy a premium appliance. My advice is that if window cleaning is going to be a regular occurrence then it’s worth investing in a good quality gizmo, especially if your house has a lot of windows, glass doors or a conservatory. That’s a lot of glass to keep clean and you need a unit that can cope with the workload!

Without further delay let’s take a look at the best window vacs available to buy today. We’ll start with the highest performing gadget and work our way down:


If you’re after the best of the best, the Karcher WV5 Premium window vacuum cleaner is leading the race. Its a great lightweight all-rounder weighing just 1.1 kgs or 2.4 Pounds.


It operates non-stop for 35 minutes and is supplied with a cleaning fluid, a 170mm suction nozzle to reach awkward corners and edges and a microfiber cleaner head. Karcher is a German brand that manufactures appliances to an exceptionally high standard.

Why should you buy the Karcher WV5? It cleans windows fast, including shower screens and mirrors. The unit can also remove condensation and pick up spills. Karcher has built this product to provide optimum results for tasks that would normally take much longer to complete. The WV5 is a comprehensive window cleaning solution that cleans and dries surfaces in next to no time.

This model comes with the guarantee of clear-view windows when used with the branded cleaning fluids, however, many users have reported that the product can be used with any non-branded window cleaning fluid for the same results, which could work out to be cheaper in the long run.




Next up is the Leifheit 51107 window vacuum with an extended running time of up to 45 minutes and fast battery charging. It is one of the lightest window vacs weighing a mere 739g or 1.6 Pounds

Why should you buy the Leifheit 51107 window vac? It’s incredibly efficient at removing water and condensation from windows and it can get into nooks that would normally be difficult to clean.


The Leifheit portable gizmo ensures leak-free cleaning from any angle and as a result, skylight windows will not be a problem to clean. Gone are the days of water dripping all over you as you try to clean overhead windows.

Owners of the Leifheit 51107 are satisfied with the product’s cleaning results and have left plenty of positive reviews, however, some owners have reported that the cleaner head can occasionally find it difficult to reach into window edges.

The Leifheit cleaner costs a bit less than the leading Karcher WV5, however, you will need to pay extra for some of the attachments. I’d advise purchasing the optional click-system telescopic handle that extends the reach of the unit to enable the cleaning of conservatory roofs and windows that are higher up.

The Karcher WV2 is the smaller brother to the WV5 at the top of our list. The compactness of the unit doesn’t compromise its performance, this little guy is powerful. As far as weight goes, the unit weighs 1kg or 2.2 pounds and it gives a total running time of 25 minutes.


Why should you buy the Karcher WV2? Often, the best things come in small packages and the WV2 is one of them. This gadget is smaller, therefore, easier to clean with. Streak-free results come as standard. You will find a generous supply of accessories including a narrow cleaning head, wide cleaning head, cleaning fluid, microfibre cloth and a spray bottle.

Its 10% smaller and lighter yet it still performs at a high level and gives an impressive finish that you would normally expect from a bigger appliance. The Karcher WV2 excels when it’s needed to reach tighter spaces that larger units would struggle with, such as decorative glass panels found on entrance doors.

The only drawback of the WV2 is a shorter running time of 25 minutes, however, the battery charge time is much shorter than the WV5 and as a result, you can get on with the job with minimum disruption. You should be able to clean multiple windows throughout your home with little hassle. Similar to its big brother, the Karcher WV2 has enjoyed plenty of positive feedback from satisfied owners.

What Should You Consider When Buying a Window Vac?

Window Vacuum Type

Conventional Handheld Window Vac– these models are similar to standard handheld vacuums and share the same dimensions but the difference is that they are designed to lift moisture and dirt from windows without causing smudges or streaks. Rather than using a motorised brush, the unit focuses its suction to suck up dirty water and ensures that nothing is left behind.


Telescopic Window Vac– The cleaning process is identical to handheld units, however, this variant is equipped with an extendable handle to clean windows on higher floors that would normally require a ladder to reach. These units provide the convenience and safety of cleaning high reaching areas from the ground level without causing any undue strain to the user.

Robotic Window Vacs– These have got to be one of my favourite appliances because I love automating domestic chores. This hands-free gadget simply needs to be placed on the glass and it will give you streak-free windows. All you need to do is pour cleaning fluid into the machine, attach it to the safety rope and press the start button. These units do require some supervision, however, if the robot runs in trouble it will alert you.

Window Vac Water Tank

Window vacuums house a water tank that collects dirty water and condensation and stores cleaning fluid. The tank needs to be big enough to pick up fluids without distracting you partway through the job to be emptied. The average tank size of a window vac is between 100ml to 300ml although larger models often come with larger capacities.


How High Are Your Windows?

Windows higher up are not easy to clean as they need you to get onto a ladder, however, it’s very uncomfortable trying to balance on a ladder and clean at the same time. A telescopic handle is the best solution to reach distant windows. Wherever possible, you should opt for a window vacuum that comes with an extension attachment or the option to buy one in future should it be required further down the line.

Window Vacuum Nozzle

The nozzle usually has the dual function of vacuum and squeegee. All you need to do is squeegee the glass whilst the vacuum collects the water into the tank.

The size and shape of the nozzle are hugely important as they determine the cleaning efficiency of your unit. A slim nozzle is great for targeting smaller areas such as bathrooms or front door windows. If you need to clean bigger areas such as glass doors then it’s best to buy a window vacuum cleaner with an interchangeable nozzle, therefore, you can swap between slim and wider nozzles. You will get through tasks quicker with the right nozzle.


How Heavy Is the Window Vac?

The weight of the unit needs to be comfortable enough for prolonged use if required. Remember that these units are used with just one hand, therefore, you want yours to weigh 1.1kgs (2.4 Pounds) or less.

Can The Window Vac Be Used Indoors and Outside?

In addition to indoor use the majority of window vacuums can be used outdoors as well, however, if you’re after a robot vacuum that can clean exteriors windows make sure you check that its designed for outdoor use. It needs to be waterproof and able to withstand the elements, especially if you live in an area that always rains like I do (sigh).

Handy Tips

Don’t panic if your window vacuum starts to leak whilst in action. The best thing to do is check the tank as it might need emptying. If the leaking persists, even when the tank is not full, then you should contact the manufacturer.


Similar to a standard vacuum, your window vac will emit some noise from the motor. Be sure to check the product specification for the audible decibel levels before purchasing, if your concerned that the noise might disrupt the people around you.

Be sure to clean the nozzle frequently, preferably after each use, to stop debris from passing back from the nozzle to the glass.

Features To Look Out For

Window Vac Accessories

Most windows vacuums come with a decent kit of accessories for different tasks. As a rule of thumb, make sure you get one with interchangeable cleaning heads for both small and big windows. Most models will come with a spray bottle and microfiber pads to get rid of debris whilst achieving a clear-view finish.



Portable window vacuums generally run on rechargeable batteries and the operating times are usually around half an hour. This might not seem like a long running time, however, the appliances are optimized to clean multiple windows in very little time. You can clean both sides of glass door in under 5 minutes. When the battery runs flat simply recharge it with the supplied
AC power adapter or micro USB depending on the model.

Extendable Attachment

As mentioned earlier, a telescopic attachment is a must-have for a 2 or 3 story home or dwelling with glass roofs. It’s much safer and convenient to use an extendable handle for high areas and tall windows instead of attempting to use a ladder. I recommend measuring the highest point that you intend to clean and check that the tool can extend to that point.

Battery Charge times

The battery charge times varies between models. High-end window vacuums are usually equipped with a fast charging feature to minimize delays when you’re carrying out bigger jobs such as spring cleaning.

Window Vacuum Pricing

Premium models normally come with longer running times to help you clean several windows in one go, however, you will need to shell out a bit more money for these although they are still very affordable for most budgets.


Wherever possible, try to buy a window vacuum cleaner that comes as part of a kit, therefore, you will be supplied with a good range of accessories to tackle multiple tasks. premium models are approximately priced between $100 to $199 and robotic window cleaners are around the $150 to $220 price point.

Other Useful Information about
Window Vacuums

  • More than just window cleaning you can use a window vacuum on mirrors, shower screens and tiles.
  • These gadgets are particularly good at getting rid of condensation from bathrooms.
  • Always ensure that the appliance is fully charged prior to using it.
  • If your windows are particularly grimy you will need to apply a detergent to clean them before using the vacuum. Most window vacuums are supplied with a cleaning fluid and spray bottle for this.
  • For best results, spray some cleaning fluid across the whole window and spread it with a microfiber cloth or squeegee then clean in a downward direction with your window vacuum. Job done!

Frequently Asked Questions

Ques. Do all window cleaning vacuums come as part of a set?

Ans. Unfortunately not. Some brands provide the basic unit, therefore you will need to buy additional accessories as optional extras. These units are often cheaper, however, I think it’s worth buying a window vacuum with a range of accessories to handle different tasks and various sized windows.


Ques. What’s the benefit of a robot window vacuum cleaner over a manual one?

Ans. Robot units provide a good level of automation, therefore, you can set it up and leave it to clean while you get on with your day although I’d recommend checking on the machine periodically. I’m a big fan of automated domestic cleaners and you’ll see that I’ve written plenty of reviews about robot vacuums throughout this site. Robots are not perfect but manufacturers are constantly improving them and the biggest advantage of owning one is the time that it frees up.

Ques. What type of cleaning fluid can I use with my window vacuum?

Ans. I’d always recommend using a window cleaning solution because the mixture is made to stop streaks. As mentioned earlier, some models are supplied with cleaning fluid, however, once that runs out you can purchase any type of window cleaning fluid of your choice.

Are you considering buying a window vacuum from our list or do you already own one? Please leave your comments in the section below. I’d love to hear from you.
