What To Look For in a Window Vacs
From researching different models, I’ve got a couple of tips for finding the best window vacs. Firstly, look for a window vac that has a battery life of at least 30 minutes. It might not sound like that long, but remember that you won’t be using the vacuum continuously. If you think you’ll need more time than this, there are some models that last up to 60 minutes, as you’ll see in the list below.
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.
I would say that different head attachments are invaluable for cleaning different size windows – particularly useful for bathrooms and sash windows.
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 vacs will have a water tank that can be removed for emptying, making it easier to clean.
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.
