This is handy if you want to use the window vac for a variety of cleaning jobs or have small-paned windows. In addition to window vacuums, there are also window cleaning robots and battery-powered window wipers.

Convenient design touches include a stopper that lets you drain the tank without needing to remove it (although you can remove it for cleaning). You may find that one of the blades has better suction power than the other, which will make it less likely to create streaks. Cleaning in this way can be a lot quicker and more efficient than using endless endless cloths or paper towels.

This Vileda WindoMatic Window Vacuum is a budget-friendly option that’s particularly useful for cleaning up condensation in bathrooms. A window vacuum, on the other hand, sucks liquids directly from the window surface into an integrated tank, by using a mechanism similar to a regular household vacuum.

Even stubborn tight spots shine in new splendour thanks to practical attachments for various applications. 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.Suction is strong and efficient right across the nozzle, so you can clean and dry into the silicone seal around your windows. None of that would matter if the Karcher didn’t clean windows brilliantly – and that’s where it really excels. With Bosch wiper blade technology, the patented power protection plus rubber coating ensures streak-free results and quicker cleaning time. 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.
