Bosch Cordless Window Vac GlassVAC (for windows, tiles, mirrors and shower, running time: approx. 35 windows, in carton packaging)

Product Information

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. 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 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. Among its many included accessories are a smaller 170mm suction head for hard-to-reach areas and a microfibre attachment to spread detergent on your windows. There’s a built-in LED battery indicator and you can buy additional batteries so that you’ve always got a fully charged one ready to go. If you’re not interested in the manual cleaning part, you can buy the product as the Bosch GlassVac Solo, which gets you the window vacuum only with the large suction head.

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.

Banish condensation and streaks with the best window vac for cleaning your windows, mirrors and more

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.

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 . To remove any streaks after using the vacuum, take a dry microfibre cloth and wipe it in a straight, downwards motion. 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.

What Is The UK’s Best Window Vac?

Most cordless window vacuum cleaners are powered by rechargeable lithium-ion batteries. In general, these give an average run time of around 35 minutes. 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. Batteries with a longer run time will generally take longer to recharge – anywhere up to two hours. 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. When cleaning windows or surfaces, you can use a variety of cleaners. The best ones to use with a window vacuum are:

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. Cleaning extras: Many window vacs come with cleaning bottles, microfibre pads and even their own branded cleaning spray. While useful, these extras are unlikely to perform any better than the stuff you already have in your cleaning cupboard. Extendable pole: A few models on our list come with, or are compatible with, telescopic or multi-section poles to help you reach high windows and skylights without wobbling up a ladder. On the downside, a pole can make the vac hard to control, especially if it’s heavy. Weight and capacity: A kilo may not feel like much at first, but after half an hour of holding the unit at arm’s length it will start to hurt – especially when it fills up with 300ml or so of dirty water. The bigger the tank, the more cleaning you can do without having to stop and empty it, but the heavier it will get. So, tank size is less important than leak-proofing and easy emptying.

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.

Once you get the hang of the cleaning process, it’ll be easier to produce a streak-free finish on windows and mirrors.
