    Better than anticipated! I bought Karcher because their products, although more expensive than many others, do what they’re supposed to do. I’d give this 6 stars if I could!

    I had my original until recently, only replaced blades. However, it did give up after many years excellent service. My replacement doesn’t seem as sturdy but must admit it does do a good job. Slightly different design which only time will tell if as good as original.

    in our family household, we have found the Krcher WV 1 Window Vac invaluable during the winter months.
    Also great for cleaning mirrors and glass shower screens.

    so glad I purchased this…. my husband leave water in the bath after a shower and this makes light work of wiping/ sucking up the water in no time. its rather addictive to use so I make sure mine its always charged up.
    my shower screen is always streak and watermark free and I love using it. lightweight and super easy to use. I would highly recommend it.

    My window cleaner having given up his round I borrowed a Karcher to do my windows. I was so impressed I bought my own. I saved the cost – compared to a window cleaner – within a couple of weeks.
    It works well on car windows, bathroom mirrors and showers too. It takes a little practice to get the best results – just don’t press hard, draw it over the glass and let the suction and squeegee do their work.

    Purchased because we get a lot of condensation on our windows on colder days. Was getting fed up with using cloths and towels. This vacuum is just brilliant. Takes seconds to wipe over the windows and removes an amazing amount of moisture. Battery life great too!

    This is basically a vacuum cleaner that sucks up water. You still have to scrum the windows, but once you run this over it finishes them off well. No streaks any more. Did 10 windows and 2 patio doors and there was still life left in the battery.

    I’ve also used it on the tiles in the bathroom, kitchen and splash backs and glass hob. Also did the car windows. It’s great that its cordless.

    Absolutely chuffed to bits with this Karcher Vac. The suction power is great and we use it on the shower screen and walls in the ensuite every day.
    We purchased the Vac a month ago and gave only had to charge it once. My Sister also got one and loves hers too. She uses hers on her tiled kitchen floor and recommends highly too.

    Absolutely love this window vacuum. It’s such a great idea and design. No need for dehumidifiers dotted around the house now. This window vacuum clears condensation from windows in no time and collects the water in a handy little container attached. Excellent value for money too.

    Am very pleased with my Karcher purchase. Its lightweight and will easily and swiftly clean a medium size shower. You can then empty the water collected in the water container ready for next day reuse.
    The unit also works well on collecting the water after cleaning small to medium sized windows.
    The instruction manual is comprehensive and the unit comes with a two year warranty.
    The charging time is around two hours and will run for around 25 mins between charges. A more powerful battery would be helpful for longer running time. Can recommend if you are looking for a reliable mid sized unit.

    I love this Karcher. Bought as a work replacement for the same model which has seen considerable use. I find this model far more manageable than the larger version, it works best with a decent lather leaving a clean, streak free shine.

  28. MagdalenaNowako says:

    We have single-glazed front door and due to high humidity in the area, we had to wipe it down at least once a day, every day. Even when wiping it with paper towels or cloth, there is so much condensation on the glass that it was running down faster than we could wipe it.

    I expected it to be a problem even for the vac but, to my surprise, the suction is so powerful that it’s not an issue. Pleasantly surprised.

    Lighter than i expected as well.

    Very good window vac. I have a lot of condensation on bedroom windows in the winter and always used to use old microfibre towels to mop it up but then bought this vac and wondered why I didn’t buy it years ago! Very light to hold and sucks up the condensation on its first sweep down the window. Used it in the shower too and its excellent. Will use it in the summer as well when I clean my glass top garden table. Since using it first time it has still kept it charge so I am very happy with purchase.

  30. HershelV33 says:

    The only fault is it needs several passes to take all the condensation off the window

    Have had several different versions of these window Vacs. This is the cheapest in the range and hence just the basic Vac with a large blade, It is great for removing condensation from large windows,the water goes into a small clear tank which you just empty when full. The charge seens to last pretty well and recharges fairly quickly. I prefer the wWV5 which comes with an aditional smaller blade which is better on small windows and shower cubicles. The downside of these Window Vacs and other cordless appliances is that the weak point is always the batery which gives out after a few years. It is then very difficult to get new batteries and if you can there are restrictions on where they can be sent to and can not be returned if you get the wrong one as caries wont touch them. In additional for this product if you do manage to get a replacement it is not cost effective as the battery for this cost about 28 so you end up dumping a perfectly good product.

    Good quality, switch is abit stiff to press but very practical, so many uses glass, mirrors, spills. Must have gadget.

    My bathroom was getting very wet after showering and patches of moisture would sometimes stay for days due to the colder weather and insufficient insulation.
    We purchased this on recommendation and are so pleased. After using this all over our bathroom about 99% of the water is removed and whatever is left can clear up much quicker. The tank fills quickly and has a fairly low max level (about 1/4-1/3 full) if you over fill whilst vacuuming it can start to leak.
    Its super quick and easy to empty. You just pull out the water tank, twist off the cap and pour it out.
    Best purchase we have made in a while to protect from mould etc in the bathroom.

    Works really fast – one swipe, water is gone. Slight drawback is the low capacity of the water container – so you have to empty it out a couple times while using it to work on large windows. Other than that, great product.

    Bough this to tackle the condensation on my windows. I use it every morning and each set of windows pretty much fills the reservoir to the max line. Great to know that water is going down the drain and not creating damp and mould. I have plastic wrapping on the windows and works fine with this too. Didn’t realise this was a smaller version than the one I wanted, as I didn’t check properly, but this is just as good as the larger one. Charge lasts quite a while and has a green light that lets you know it is charging and goes off once full charged. Would recommend for anyone with condensation issues.

    This is a great wee thing and overal brilliant, however, the base is so chunky it doesn’t allow for windowsills, therefore the very bottom (a bout an inch) doesn’t get touched unless I turn upside down. Other than that, I love it!
