We had the previous model to this and this one is so much better.

I have had this Karcher window vac for about six months & I love it. It saves so much time cleaning my windows & there is less mess than cleaning with bucket & sponge, then wiping down. No streaking like with spray on window cleaner & a cloth either. I recommend you take the time to learn how to use it, it takes a couple of times to get it right for your own windows. My only complaint, which is very small, is that the spray bottle leaks when turned on its side.

The first unit purchased Dec 2016, replaced in Oct 2017, 2nd Unit replaced Sept 2019, both unit showing fully charged but on operation red light showing possible motor fault. Now on WV6 plus thanks to upgrading from bunnings customer service as WV5 was out of stock. We love this product The Karcher 2 yr warranty is really beneficial and despite our problems, we will pursue with this product

I purchased this recently and was amazed how efficient it was. Using only 500ml of cleaning solution, I cleaned every window inside and out of a four bedroom house without creating any mess. However, I did find it necessary to buff the windows with a soft cloth after using the cleaner to remove some streaks but overall a brilliant finish.

We have a Karcher pressure washer which has provided years of excellent service and I was given the window cleaner as a present. Used it twice, worked okay but couldn’t really work out why it needed anything more than the squeegee - and the suction bit seemed like a gimmick. We took it to the tip during a household cleanup.
