Window Vac Reviews

Editors Choice
  • Capable of creating a streak-free shine when used with the correct technique
  • Good build quality with a well-moulded plastic body
  • Different size attachments make it easier to clean both small and large windows
  • Different size attachments make it easier to clean both small and large windows

  • Spray attachment is very small so needs frequent refiling
  • Handle design does not always make it feel secure to use at awkward angles e.g. cleaning window exterior from inside
  • Suction does not reach the edge of larger blade so large overlap is required
  • Removing any final streaks may need to be done with a cloth after vacuuming

Bosch is certainly a well-known company when it comes to making quality tools, and their GlassVAC cleaning system is another well-thought-out offering from the German corporation.

There are both positives and negatives to its overall design, but in terms of performance it works very well and is capable of producing a streak-free shine on glass surfaces, which is ultimately the main aim when using these vacuums. For this reason, I’ve chosen it as the best window vacuum overall.

Two differently-sized vacuum heads come included, which facilitate the cleaning of large and small windows, as well as a spray bottle with a Velcro-backed microfibre cloth attachment.

Using the vacuum effectively takes a bit of trial and error to begin with, but it is possible to avoid creating streaks. The appearance of streaks is greatly reduced by starting with a very wet window and overlapping by 10 cm on each stroke, as well as using more detergent than you might expect.

Overall, the quality of the whole unit seems robust, and the handle has an ergonomic shape. However, it’s perhaps not quite as well designed as the handle on the Kärcher Window Vac, as the Bosch doesn’t completely enclose your hand. This can lead to feeling like you might drop it when cleaning at more awkward angles, like the exterior of upstairs windows, although there is a wrist strap provided.

The vacuum’s water tank has a capacity of 100 ml, which is comparable with other window vacs in the same price bracket.

It has an integrated lithium-ion battery which is simple to charge using the included micro-USB charger. The battery lasts for approximately 30 minutes of continuous use, and has a battery indicator to warn when it needs to be plugged in.

Whilst the suction and power is relatively good, the suction power doesn’t reach fully to the edges of the larger vacuum blade. For this reason, a large overlap is necessary when using the window vacuum, otherwise streaks can be created by the water residue.

Even so, a good finish can be produced one the technique is in place, and the Bosch is one of the best window vacs for cleaning windows of different sizes thanks to the attachments included.

Runner Up
  • Two blades included for easily cleaning different-sized areas
  • Changing attachments and emptying water tank takes just a few seconds
  • Lasts around 35 minutes on one full charge
  • Handle feels comfortable and secure enough for cleaning exterior windows from inside
  • Comes with cleaning concentrate included so you can start cleaning straight away

  • Microfibre cloth may still be required to buff out some streaks
  • When reaching the bottom of the window, the body of the vacuum gets in the way and makes it hard to get all the water
  • Water may pool at the bottom of the windows so a small cloth is needed to mop this up
  • Charging to full capacity takes a relatively long time - around 190 minutes

A lot of comparisons are often made between the Bosch GlassVAC and this Kärcher WV5 Window Vac. Whilst there are a lot of similarities, the two primary differences seem to be that the Kärcher has a slightly longer battery life, and offers the possibility of changing the battery when it finally bites the dust.

Whereas a lot of rechargeable lithium-ion batteries are encased inside the machine, meaning once they run down for good the tool has to be thrown away, the battery inside the WV5 window vacuum can be swapped out for a new one. I’ve identified it as the best window vacuum for versatility, for its exchangeable battery as well as other features.

In terms of general performance, one charge will last for approximately 35 minutes, which is generally enough time to clean all of the inside windows of a standard house. This window vacuum also seems to approach the windows with relative vigour; it’s powerful enough for the 100 ml water tank to visibly contain liquid after cleaning one pane of condensation.

A spray bottle with a microfibre cleaning head comes included, as well as two differently-sized vacuum blades. These measure 17 cm and 28 cm across, making them slightly larger than the blades supplied with Bosch’s GlassVAC machine.

The Kärcher WV5 has an enclosed loop handle, which makes it comfortable to use when cleaning the outside of windows from inside the house. However, as with most window vacuums, some streaks can be left after use but that’s where the microfibre buffer comes in handy.

Due to the inclusion of two blades, the reasonable battery life, ability to replace the battery, and the secure handle, this is one of the best cordless window vacuums in terms of versatility. The WV5’s blades are slightly larger than those of the Bosch GlassVAC, so it may not be as good for cleaning smaller windows, but otherwise it seems a comfortable and effective tool for both removing condensation and cleaning.

The enclosed handle makes it particularly good for cleaning exterior windows.

Also Good
  • Lightweight which makes it easy to use quickly every day
  • Good battery run time - will last a long time if only used for a couple of windows daily
  • Works well to get rid of condensation from windows and shower screens
  • Robust construction without any small removeable components (except for the water tank)
  • Water tank can be cleaned in the dishwasher

  • Despite having two power modes, the low-power mode is unlikely to be used often
  • May push water to the bottom of the window instead of vacuuming as it goes
  • No smaller blade provided which would be useful for smaller windows and awkward areas
  • No spray bottle included to help with window cleaning

This Vileda WindoMatic Window Vacuum is a budget-friendly option that’s particularly useful for cleaning up condensation in bathrooms. It can be also be used for window cleaning too, but there’s no spray bottle included for washing the windows first.

This window vacuum has a very lightweight construction and it’s well designed. It has an enclosed, ergonomic handle which makes it comfortable to use. As a unit, it’s sturdy, with no separate parts or components; the only bit that disconnects is the 100 ml water tank so that it can be emptied and cleaned.

It has a good battery life and won’t often need charging, especially if only being used for a few windows at a time. When it is time to charge, the WindoMatic window vacuum simply hooks up to a mains charger.

Although it’s a window vacuum cleaner with two power modes, there isn’t much demand for the lesser of the two. Even the high-power mode can lack strength sometimes, although it will still get the water up eventually. Occasionally, it pushes moisture down the window instead of successfully vacuuming as it goes, so the water needs to be sucked up from the bottom of the pane – which it manages to do.

The flexible neck improves how well the WindoMatic window cleaner can get into corners, but it still doesn’t get all the way to the edges. There’s only one cleaning blade included, and it’s 27 cm long, so it’s a better choice for people cleaning larger surfaces as opposed to smaller windows.

Overall, this is the best window vacuum to buy on a budget. It’s ideal for removing condensation because it is light and not overly expensive. It can also be used for window cleaning, even though it doesn’t come with any of the accessories of higher-end models, but the process may take longer.

  • Efficient at mopping up water marks and removing window condensation
  • Lasts around 30 minutes on one full charge
  • Doesn’t leave streaks or marks
  • Good value option with a simple and basic design

  • Water tank cannot be removed which makes it difficult to clean well
  • No smaller blade included so not suitable for cleaning small windows
  • Water reservoir is just 60 ml and fills up quickly so needs regular draining
  • If water pools at the bottom of the window, it is difficult to reach with this vac
  • Can't be used horizontally

If you’re after a window vac that will get the job done without being too expensive, the Beldray BEL0749 Cordless Window Vac offers a good middle balance of power and performance. This window vacuum works sufficiently well to be a worthwhile purchase, without leaving your bank balance in tears.

It’s the best window vacuum if you’re after value for money. It has all the basic functions without any additional mod cons. The window vacuum comes with one 28 cm cleaning blade, an ergonomic handle with easy-reach power button, and a 60 ml water tank.

This electric window vacuum will clean off condensation, as well as dry off windows, although you may also need to have a cloth to hand as well.

This window vacuum reduces the amount of time spent drying windows/mirrors/tiled surfaces compared to using a cloth on its own, but the vacuum isn’t always able to clean to the bottom of the window as the sill gets in the way. This is where the cloth comes in, to collect the water at the bottom.

It also shouldn’t be turned horizontally, according to the instructions, so it can’t be used along the window sill on its side.

Overall, this window vacuum is a good choice if you’re after a basic, value-for-money model. It’s capable of cleaning up condensation, and can be used for window cleaning too. However, it may leave a few streaks that need to be buffed out with a cloth.

It also isn’t possible to remove the water tank entirely, making it a little hard to clean.

  • Can run for up to 60 minutes from one charge
  • Relatively large blade is suitable for cleaning bigger surfaces
  • Rubber grip is soft and comfortable

  • You will likely require a cloth to catch any water than isn't vacuumed up
  • Lower power can sometimes cause drips to fall down the window
  • No additional accessories included, like a spray bottle or extra blade

If you’re working across large surfaces like bathroom tiles, the battery capacity and blade size of this AEG Window Vac could work together to make the job easier.

With a run time of up to 60 minutes, this is  one of the best cordless window vacuums featured here in terms of battery life. It’s powerful enough to remove condensation, and clean windows, as well as clear spills on hard-top surfaces.

However, this window vacuum doesn’t seem to have as strong suction power as some of the higher-end models featured here. Therefore, although the AEG Window Vac can be used both for cleaning windows and removing condensation, it can lack the power to collect all of the water.

For this reason, it’s a good idea to have a cloth nearby to catch any drips.

The water tank is the largest of all the window vacs on this page, with a capacity of 110 ml, so frequent emptying of the dirty water won’t be necessary. There are no additional accessories included like a second cleaning blade or spray bottle.

One final thing offered by the AEG Window Vac, which is a little whimsical but still worth mentioning, is that it comes in a choice of colours. If a certain theme would go better with your bathroom, you can choose between ‘baltic blue’, ‘aqua spray’ or ‘vivid viola’, purely for aesthetic purposes.

Clive's Smart Buying Tips

  1. From researching different models, I’ve got a couple of tips when it comes to choosing the best window vac. Firstly, look for a window vacuum that has a battery life of at least 30 minutes. It might not sound like much, but remember that you won’t be using the window vac continuously whilst cleaning. Still, if you think you’ll need more time than this, there are some vacuums that last up to 60 minutes, as you’ll see in the list below.
  2. To help make jobs easier, choose a window vac with multiple head attachments. If they don’t come included, at least check whether there are compatible attachments that could be purchased later down the line if required. A 280mm suction head is the standard size, but a smaller head (around 170mm) will allow you to clean tighter spaces.
  3. I would say that different head attachments are invaluable for cleaning different size windows; they’re particularly useful for bathrooms and sash windows.
  4. Now a note on maintenance – it’s easier to clean the window vac if it has a removable water tank. The water tanks collect the dirty, waste water from the windows, so they can get a little grimy over time. Many of the best window vacuums will have a water tank that can be removed for emptying, making it easier to clean.
  5. Finally, you might want to look out for a window vac with some additional cleaning accessories included. Some models come with spray bottles and microfibre pads which can make it easier to achieve a streak-free finish. These generally offer better value for money as well. 

After comparing several window vacs, I’ve chosen the Bosch GlassVAC as my top choice. It has a rechargeable lithium-ion battery that has a battery life of approximately 30 minutes (enough to clean up to 35 windows). It comes with a standard cleaning head and a smaller option, as well as a spray bottle and Velcro-backed microfibre cloth.

How to Choose The Best Window Vac

Window vacuums make it easy to clean windows, mirrors, shower screens and reduce condensation. Cleaning in this way can be a lot quicker and more efficient than using endless endless cloths or paper towels.

These fun tools work by hoovering up liquid and removing all the dirt from the windows, leaving a glistening, streak-free finish.

If this has piqued your interest, below you’ll find useful information about how to choose the best window vacuum and how to get the most out of it:

Uses For Your Window Vacuum

Cordless window vacuum cleaners can do so much more than just clean windows. Here are a variety of ways that a window vacuum can come in handy around the home (and beyond!).

Window vacuums can remove condensation from:

  • Tiles
  • Windows
  • The inside of tents (perfect for keeping dry on camping trips!)
  • Conservatory windows and doors
  • Caravan interiors

Plus, window vacuums can clean:

  • Mirrors
  • Windows
  • Kitchen worksurfaces
  • Fridges and ovens
  • Shower screens
  • Cars (you’ll be amazed how polished a finish you can achieve!)
  • Greenhouse glass windows
  • Spillages on kitchen worksurfaces or hard floors

Make sure that the blade of your window vac is clean and undamaged, especially when using it on glass surfaces or on more delicate painted materials like the body work of your car.

As mentioned, one of the primary uses for window vacuums is to remove condensation from windows. This can help reduce the damaging effects of damp, particularly in bathrooms, by removing moisture before it can be absorbed by wooden windowsills, shelves, cabinets or paintwork.

It’s also worth nothing that, whilst many window vacuums can be used to clean pretty much any hard, flat surface in the home, some don’t work well horizontally. For this reason it’s worth checking their product specifications carefully before making a purchase.

Battery Type and Run Time

Most cordless window vacuum cleaners are powered by rechargeable lithium-ion batteries. In general, these give an average run time of around 35 minutes.

Some models, such as the AEG Window Vac can achieve around 60 mins of running time from one charge. This can be useful if you have several cleaning jobs to be doing in one day, although normally 30 minutes is more than enough for the majority of tasks.

Batteries with a longer run time will generally take longer to recharge – anywhere up to two hours.

Also it’s worth being aware that there are two different styles of rechargeable battery in window vacuums: batteries that can be removed, and ones that are integrated into the machine.

If the battery is integrated into the machine it will be charged via a micro-USB cable or mains adapter. Once the battery comes to the end of its life, you will have to buy a new window vac.

Some products, such as the Kärcher Premium Window Vac, have batteries that can be replaced. You can buy replacement lithium-ion batteries without having to replace the whole machine.

What’s more, if the battery is removable, you can even interchange it with another charged battery when the first one runs out of power. In this way, you can use the window vac for an extended period of time without having to stop to wait for the only battery to recharge.

Creating a Streak-Free Finish

It can take a bit of trial and error to work out how to most effectively use a window vacuum. Whilst all styles are a little different, there are some common steps to follow across the board. Once you get the hang of the cleaning process, it’ll be easier to produce a streak-free finish on windows and mirrors.

  1. First you need to mix a cleaning solution. This might be a window-specific cleaning solution, or warm soapy water. Experiment with different cleaners to find which delivers the best results with your vacuum.
  2. Clean the surface using this solution in a spray bottle with a microfibre cloth – some cordless window vacuum cleaners come with these items provided. You can also use a sponge or other application method. Most importantly you should make sure the surface is wet, not just damp. This can make all the difference when looking to avoid streaks.
  3. Choose the correct window vacuum head for the job. Some vacuums come with multiple heads so you’ll be able to choose between a smaller and larger blade. You may find that one of the blades has better suction power than the other, which will make it less likely to create streaks.
  4. Turn on the window vac and glide the vacuum smoothly over the wet surface in downwards motions, sucking up the water.
  5. To remove any streaks after using the vacuum, take a dry microfibre cloth and wipe it in a straight, downwards motion.

Tip: If you can hear a squeaking noise as you vacuum the surface, the surface isn’t wet enough. This can lead to streaks. You shouldn’t hear any squeaking when using the window vac.

Extra Cleaning Tips

Here are a couple of extra tips for achieving a streak-free finish on windows and mirrors when using a window vacuum.

Post-Clean Buffing

As mentioned above, buffing the surface with a dry microfibre cloth is the best way to ensure a perfectly streak free finish. Don’t go in circular motions, simply run the cloth over the surface in the direction that you used to vacuum.

Cleaning Solutions

When cleaning windows or surfaces, you can use a variety of cleaners. The best ones to use with a window vacuum are:

  • A solution of water and washing up liquid
  • A diluted white vinegar solution
  • A glass cleaner made specifically for windows or the surface you are cleaning

Don’t feel that you have to go out and buy something special, washing up liquid and vinegar are extremely effective at cutting through grease.

How Often to Clean Your Windows

If you like using your window vac on your outside windows, to keep them clean and shiny, you’ll want to be cleaning them at least 2 – 3 times per year. Of course, you can clean them more often than this, but for typical residential properties which aren’t by a train line or main road, this should be sufficient.

Clean Condensation Every Time

If condensation is a big problem in your bathroom, it’s great to get into the habit of using a window vac after every shower or bath. Cleaning the condensation from the shower, bath, mirror and sink will dramatically help reduce how much water is left to evaporate into the room.

Window Vac FAQs

Some cordless window vacs come with two heads, a small one and a larger one. This is handy if you want to use the window vac for a variety of cleaning jobs or have small-paned windows. Window vacuums with one blade will work well on larger windows and large areas like shower screens and tiled walls. If you need to clean smaller areas, then it will likely be worth paying extra for a window vacuum with several blade heads.

Some window vacs also come with a spray bottle that has a microfibre cloth attachment. This makes it easy to apply cleaning product evenly and can help with lifting off stubborn stains and marks.

If your window vac doesn’t come with one of these, you will need to use a sponge or separate microfibre cloth to wash the window before using the window vacuum. Ensuring that detergent is applied evenly can be more difficult without the help of a spray bottle, but it’s not impossible.

Most window vac manufacturers sell a detergent to use with their products. These should be designed to produce a streak-free finish whilst using their specific machine.

However, there are other options. You can also use a solution of washing up liquid and water, a diluted vinegar solution, or a glass/mirror detergent (depending on the surface you are cleaning).

Make sure that the surface is sufficiently wet before starting to use the vacuum. If the window vacuum is squeaking, the surface isn’t wet enough. Move the window vacuum in straight, downwards motions. Once finished with the vacuum, take a dry microfibre cloth and wipe the window using downwards strokes. When going over with the cloth, pay special attention to any lines left by the edge of the window vac.
