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. 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. What extra features and accessories are worth having?
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. None of that would matter if the Karcher didn’t clean windows brilliantly – and that’s where it really excels. Suction is strong and efficient right across the nozzle, so you can clean and dry into the silicone seal around your windows. The finish is about as streak-free as a window vac can achieve, although you may want to give your glass a final buff with a dry kitchen towel. Most cordless window vacuum cleaners are powered by rechargeable lithium-ion batteries. In general, these give an average run time of around 35 minutes. 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.Handle design does not always make it feel secure to use at awkward angles e.g. cleaning window exterior from inside 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. 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.
Interchangeable suction heads: Most window vacs come with a 280mm suction head as standard, but many include an additional smaller head for fiddly jobs such as leaded windows and front door panels. Pivoting suction heads can also help to get into awkward spots. 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. Bosch window vacuums score with a long battery runtime of 30 minutes. That's enough for an area of 105 square meters or for up to 35 windows. STEP 3– Turn the GlassVAC on, and run it over the wet surface – leaving a smear/streak and liquid free surface. It literally hoovers up the dirt, and any excess water. I would say that different head attachments are invaluable for cleaning different size windows; they’re particularly useful for bathrooms and sash windows.
What Is The UK’s Best Window Vac?
The compact design allows for easy handling. Even hard-to-reach places and corners can be cleaned conveniently. 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. 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.
