I sprayed the cleaning solution on the harder-to-reach areas of the shower screen first, then turned on the window vac. I moved in a vertical direction and could see the buildup (almost) vanish. This was a great result. I have to say I was impressed by the results. Surprisingly, I didn't have to repeatably go over the area with the spray bottle, and the squeegee blade wiped away all of the diluted concentrated cleaning liquid to reveal a shiny surface – with no water marks to be seen.

I sprayed a generous amount of the cleaning solution over the window, then working the Karcher window vac vertically down the pane. I started with the smaller squeegee head, but later switched to the larger one to cover more surface area at once.The water tank/collection bottle can be easily emptied by undoing the rubber bung and the whole water tank can be removed for cleaning (although you have to detach the vac head to do this). The cleaning cloth is attached by Velcro so can easily be removed for washing (in a washing machine). I also have a Karcher window vac. It's brilliant for clearing condensation and also for cleaning the windows.” Rated by Mumsnet user Clarice99 Our verdict The set consist of 2 extending poles; one for the window vac and a separate one that has a washable cleaning head attachment. Each pole is 1.2 metres in length but can be extended to 1.9 metres. Your Karcher window vac can be securely mounted on the base plate and attached with the rubber strap. Reviewer Mel lives in a three-bedroom house in Sussex with her husband, two teenagers, three cats, three degus, two tortoises and a hamster called Winnie. So, what can the window vac be used for? Well obviously, the main use is for cleaning windows but in our experience, it can also be used for cleaning shower doors and removing condensation from surfaces. The window vac is extremely versatile and we found it particularly useful for cleaning up liquid spills but you may find it handy for other applications. In fact, it will perform great on all smooth surfaces. What’s in the box?

The battery arrives with just six minutes of power, so I first needed to set the appliance to charge. This took no longer than a few hours, and I could watch the battery indicator count up, minute-by-minute. Once it reached 100 minutes, we were ready to clean up to 300m² on one single charge. 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.

We only had to re-do a few small areas. We only used washing up liquid in the cleaning bottle but overall the windows looked clean and streak-free when we’d finished. We must mention that there was some stubborn bird poo on the window and we had to redo this area. We feel that if your windows are extremely dirty then some preparation might be needed beforehand to ensure the vac is as efficient as possible. 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.
