Bosch GlassVac Cordless Window Vac Review

The Bosch GlassVac Cordless Window Vac is an extremely effective window vacuum that is powerful and easy to use.

It has an integrated lithium-ion battery which is simple to charge using the included micro-USB charger.

The vacuum comes with a small and large blade head which can get into the majority of spaces. The vacuum effectively sucks up the water leaving a virtually streak-free shine.

You get around 30 minutes of continuous use from a single charge and the vacuum has a battery indicator to let you know when it needs to be plugged in.

The waste water tank holds up to 100 ml of water and is easy to empty.

To help lift dirt and make the cleaning process easier, the set also comes with a spray bottle with a detachable microfibre cloth.

Again, this is a great tool for creating sparkling windows, streak-less mirrors and glistening tiles.

Vileda WindoMatic Power Window Vac Review

The Vileda WindoMatic Power Window Vac runs on a powerful lithium-ion battery and can clean up to 120 windows on one charge.

It has two power modes, with its max-power setting producing 50% extra power, meaning this is a super efficient window vac.

These two suction settings make it even easier to achieve a streak-free shine, assisted by the 27 cm blade with a flexible neck. 

The water tank is easy to remove and clean – you can even put it in the dishwasher – and it holds up to 100 ml.

This vac does not come with an additional head or a spray bottle like some of the other models I’ve reviewed; however, it’s a really worthwhile purchase for cleaning larger windows.

You can use a separate spray bottle and any cloth to apply cleaner to the windows before vacuuming.

This is a well-priced, high-quality product – the price is kept low because there are no accessories included, but the basic unit is highly effective.

Beldray Cordless Rechargeable Window Vac Review

The Beldray Cordless Rechargeable Window Vac has a neat and compact design and is considerably cheaper than some other vacuums on my list.

It is light to use and does a good job on windows and shower screens.

However, it can only be used in a vertical position so its not possible to use to clean up spills or on horizontal surfaces such as worktops or shower trays.

The water tank can hold up to 60 ml of water so also needs emptying more often than the larger products.

This vac does a decent job on vertical surfaces but it’s not quite as suitable for awkward corners or horizontal cleaning.

Kärcher Premium Window Vac Incl. Accessories Review

The Kärcher Premium Window Vac is a well-known, trusted product from a reputable brand.

If you’re looking for streak-free windows, mirrors, and shower screens, this is one of the best window vacs for the job!

It comes with a spray bottle that has a microfibre cloth head – you use this first to spray/wipe on detergent to soften the dirt.

Afterwards, you use the vacuum unit to suck up dirty water leaving a streak-free shine.

The vacuum comes with two changeable blade heads meaning it’s suitable for both large areas and tighter spaces.

The waste water tank holds up to 100 ml and is easy to empty.

It has a fantastic battery life, able to clean for up to 35 minutes on a single charge. The lithium-ion battery can then be easily recharged in 185 minutes.

The battery can also be removed and replaced when it reaches the end of its life, meaning you don’t have to replace the entire product.

This vacuum kit comes with the unit, charger, battery, two heads, spray bottle, and microfibre cleaning cloth. Everything you need to get the job done!

If you’re anything like me, you’ll get hooked to using this window vac – it can clean even grubby outside windows and the finish is so pleasing to look at.

Plus, it’s a great tool to have for the bathroom. It keeps showers, mirrors and tiles streak-free, and can even be used to suck up spills.

AEG Rechargeable Window Vac Review

The AEG Rechargeable Window Vac has a run time of 60 minutes allowing you to get plenty of cleaning done on one charge.

The battery then takes two hours to fully recharge.

It’s a little heavier than some vacuums, weighing 1 kg, but offers great run time as a result. Plus, it’s still lightweight enough to use for long periods without making your arms ache.

The head has a rubber blade that gives a good streak-free shine.

Thanks to its 110 ml water tanks you don’t have to stop to empty it very often and can use it to vacuum up condensation, too.

This vac was easy to use and gives good results, however, it does only have one blade and doesn’t come with a spray bottle or cloth.

It’s not as powerful as some other models but it does have an excellent run time. Again, this is one of the best window vacuums to buy on a budget.

Things to Know Before Buying a Window Vac

Window vacs make it easy to clean windows, mirrors, shower screens and condensation. Cleaning is a breeze; quick, efficient, and without the need to use endless cloths or paper towels.

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

If this sounds right up your street, keep reading for useful information about how to choose the best window vacuum and how to get the most out of it:

Window vacs can do so much more than just clean windows. Here are a variety of uses for your window vac:

They can remove condensation from:

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

And 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

The best window vacs can be used to clean pretty much any hard, flat surface in your home. However, some window vacuums don’t work well on horizontal surfaces – so check this in their product specifications before making a purchase.

As mentioned, aside from making time-consuming, labour-intensive cleaning jobs an absolute breeze, they’re also great for tackling condensation. Window vacs are an excellent tool for removing excess moisture from places where damp can build up easily.

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.

Most window vacs 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 Rechargeable Window Vac can get 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 jobs.

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

It’s good to be aware that there are two different styles of rechargeable battery in a window vac: 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.

The following is information on how to get the most out of your window vac, and use it effectively to get the best finish possible.

  1. First you need to mix a cleaning solution – be this a specific window-cleaning solution or warm soapy water.
  2. Clean the surface using this solution in a spray bottle with a microfibre cloth – some window vacs come with these items provided. You can also use a sponge or other application method. Make sure the surface is wet.
  3. Choose the correct vacuum head for the job – if your window vac comes with a choice of vacuum heads you’ll find it easier to adapt your vacuum to different jobs.
  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, 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 Tips

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 window vacs come with two heads, a small one and a larger one. This is handy if you want to use the vac for a variety of cleaning jobs or have small-paned windows. Those with one blade will be okay for larger windows and large areas like shower screens and tiled walls.

Some window vacs also come with a spray bottle that has a head to which a microfibre cloth can be attached. This makes it easy to apply the cleaning product evenly and will lift off stubborn stains and marks. If your window vac doesn’t have this, you will need to wash the window with detergent and water and then use the vacuum to suck up the dirty water.

Most window vac manufacturers sell a suitable detergent to use with their products – these have been designed to produce a streak-free shine on hard surfaces. However, you can also use washing up liquid and water, a diluted vinegar solution, or a window detergent.

Make sure that the surface is sufficiently wet before starting to use the vacuum. Vacuum in straight, downwards motions. Once finished with the vacuum, take a dry microfibre cloth and wipe it in downwards strokes on the surface. Pay special attention to any lines left by the edge of the window vac.
