      • "'dirty' water tank a little small"

      a vac for windows

      I do have a problem with condensation appearing on my windows - despite them being double glazed and those moisture absorbers and a dehumidifier reduces it but not stop it. So I was going through a lot of paper towels wiping it up in the morning. When I saw these advertised I thought that if the price was reasonable why not get one it was on offer for £47.99 from my local homebase at the time.

      The unit is rechargeable which is the advantage of not using something which is mains operated where there is water. A full charge does take a few hours but I can do my windows many times off one charge. The squegie is large and so a few wipes down the window are all that is needed. The condensation / water is drawn into an inbuilt tank which holds about 100 ml of water so it doesn't end up going all over your window sill. I have found it to be very effective at removing the condensation quickly and easily and leaves my windows dryer than the paper towels I used to use ever could. I have also started to use it on the windows in the flats communal area as well when they need a clean. The squegie leaves no streaks on the glass which is also a big bonus.

      The unit is't overly heavy at around 600 g (empty) and the handle is easy to hold and turn off and on. One of the draw backs is that there is no charge left indicator you sort of know when it needs recharging as the vacuum begins to struggle slightly.The water tank is easy to empty and the squegie can be removed from the unit so you can clean it. Although I do think the water tank is perhaps a little small but as it is easy to empty it isn't a major problem.

      I think this is a great product Easy to use. I can get my windows done in half the time and it's streak free. Great for cleaning the mirrors in the house as well as the shore screen. Well worth the money. I have the accessory kit with includes the Karcher cleaning solution and this really is good better than using an "off the shelf" product. So I would highly recommend this to anyone.

      Good overall cleaning device

      It is hard to clean the wiper blade on this product as they tend to get quite messy from the dirt and water on your windows. It takes roughly twenty minutes for me to thoroughly clean the wiper blades after each use. This is longer than I actually spend wiping clean eight windows.

      Can be tricky to get it to suck up the water on the lower parts and sides of your windows as I find that you have to turn it on its side or upside down at times. This results in either cold air hitting you in the face or if you are wearing short sleeved shirts it will freeze your arms. Water can also come spurting out of the container when it is in these positions. A problem with the device is that if you use it upside down you will burning the motor out. I think that this is an aspect of this device that seriously needs some rethinking.

      This product is a lightweight measuring in at 0.7kg which means that it can be easily used for long periods of time but I sometimes find that it can make your arms tired due to the constant movements and the resistance from the device even at this light weight. Maybe I just need to hit the gym a bit more often.

      Battery life is rather good as you should have more than enough to be able to get around your entire house and maybe have a little bit extra before you need to put it on the charge. The battery's health should also not deteriorate much over its life span as it is a lithium battery which means that you can recharge it and instead of it losing a percentage of the amount it can recharge each time it always recharges fully.

      The product is extremely effective at sucking up water and it will leave literally zero residue on your windows or any other surface that you use it on. It leaves a nice clear view on your windows without any streaks and is basically as good if not better at drying your windows than it is to do it by hand with a lot of extra work to get them to not look streaky.

      It is rather easy to empty the container that collects the water that the product sucks up. This is because you can either just take the black bung out of the device and tip the water out that way or you can detach the container. The container detaches by simply holding in two black buttons on the side of the top of the handle. This detaches the entire top section of the device and then you can simply lift off the water container. You can then twist and remove a large black bottle top and pour the water out from that. This also allows you to get easy access to the container to clean it thoroughly if it gets mouldy.

      The container also holds quite a bit of water at 100ML which means that you should be able to roughly get about one empty after every two uses if you have a lot of water on your windows. The container is made from a strong plastic which makes me think that it will last a long time. I have had the device for about several months now and I find that it has no signs of wear and tear and still functions perfectly with a perfectly healthy battery.

      I have not noticed that if you leave about a quarter to a fifth of the limit of water in the device's container for a couple days that it will start to smell and congeal. I do however tend to use across these days even though I do not empty it and this is mainly the water off the walls from my shower.

      The Karcher recharges rather quickly as I find that it only takes a few hours to reach full battery again from empty. This means that it is always ready to use basically as if you use it on your windows in the morning then you can use it on your shower at night instead of having to wait till the next day before you can use it again.

      The charger is rather good as it is built in and this stops it having to take up a lot of space in your house. To charge this device you simply plug it in with the cable provided into a slot on the bottom of the back of it and then plug it into a wall socket. Overall the whole device with the charger an all only takes up about 2-3 feet in width with about 2-3 feet in height. It is not overly large and is just a good size for anybody.

      This is an extremely good product for £50 and I would recommend it to anyone who has a lot of windows to clean as it will greatly reduce the amount of time and care you have to put in to get them clean and gleaming. Only faults I have with this cleaner is that it has in my opinion a couple of little design flaws it does however not stop me from admitting that it is a brilliant device.

        Great product

        This is a brilliant device as it lets you clean windows in a matter of minutes with less hassle than the more traditional ways. With this device you simply wash the window and then turn the cleaner on and it sucks up all of the liquid off the window leaving absolutely no streaks on the window. It is the same as putting a lot of effort into cleaning your windows with newspaper except it only takes seconds and has the exact same results.

        The liquid container does not need to be emptied every time you use the device and you can sometimes get about four uses out of it depending on how many windows you have and use it on. The container does not detach from the cleaner but instead you remove a rubber bung and tip the water out.

        This device is best suited to being used held upright as if you hold it any other way it can spit water out at you or blow cold air up your arm and in your face which is not overly pleasant.

        The cleaner does not need recharged often as it does hold a lot of power however if you are doing a lot of windows you might have to recharge it each time or every other time.

        For the price of £50 I think that it is a bargain because of how much time and hassle it can save you over time. I have had this product a few months and love it that much I would recommend it highly to anyone.

        I have also found that if you have a shower and your walls tend to get soaked that you can easily take this device and dry your walls in seconds much like your windows.

          A great unit, well worth the RRP. Makes cleaning windows a doddle.

          I'd been looking to purchase a Karcher 'Window Vac' for a good year, hesitating every time the price crept down. When I found out a family member had purchased one, I was kindly offered the chance to test it. I jumped at the chance!

          PRICE
          There are many different models of the Window Vac available on today's market. The WV50 is the 'first edition' and is therefore priced accordingly at around the £59.99 RRP, but is often found on sale. You can add to the unit by buying add-ons, such as a wider blade and microfiber spray bottle and the WV50 can be found packaged up with accessories at a higher price.

          PERFORMANCE
          I put the WV50 to the test on our mucky windows, covered in sticky hand prints (left by the toddler) and nose marks (left by the cat), so it had a tough trial ahead of it!

          Start by charging the unit up initially, which takes roughly two hours from empty. Next step, I used my usual microfiber cloth which was wetted in a bucket of warm water and vinegar (Karcher produce a specialist solution which is meant to optimise the performance of the unit) to clean the window and loosen the dirt. I placed an old kitchen towel on the window ledges of any internal windows to stop and mess. I then turned on the unit and started from the top left of the window and guided the WV50 gently down until the entire window was dry, clean and (most importantly) COMPLETELY STREAK FREE!

          I would say the only disadvantage of the WV50 is the battery life, which stands at around 20 minutes. Its not possible to do all the house inside out (especially if you have a conservatory). But this gives a good excuse for a good two hour break whilst the unit recharges!

          OVERALL SATISFACTION
          I was honestly amazed at how easily the WV50 cleaned our windows and soon rushed out to buy after the trial. Using the unit is still a 'gimmick for us' which makes cleaning windows fun and the various accessories will definitely be on my 'to buy'/birthday/Christmas list!

          Well worth the RRP, let alone the often reduced price. I have recommended to all my friends and family.

            A must buy for cleaning windows.

            I bought this product from Argos for a steep £49.99 after seeing a television advert about it. I bought it because my house has single glazed windows which mean we get a lot of condensation in the winter (if we don't remove the water it will cause mold).

            I don't recommend this product for clearing windows of condensation - although it us very effective at getting all the water off windows, the condensation will just come back very quickly (within about 10 minutes of cleaning) so do not make the same mistake as me by buying this product for condensation, get a dehumidifier instead.

            For cleaning windows this product is nothing short of flawless! I have been cleaning my windows with a cloth and bucket for years and I would never go back. It just glides over your windows cleaning them effortlessly and with with speed. It is also cordless so no annoying leads.

            You can get a special cleaning product for this but I don't recommend using it as it is expensive and not that effective. Honestly, you are better off just mixing a bit of washing up liquid with water and it won't harm the machine or anything.

            There are a couple of ways I can flaw this product, first of all with the battery life - it takes hours to charge and I only get about half an hour of cleaning time before you need to charge it again (and you can't just give it a quick charge or it will go weak).
            You also have to keep your eye on it because if you go past the 'max' line it will start spraying water onto your face through the vacuum and this can be very painful, especially if you've been using a cleaning product and it gets in your eyes! It also fills up very quickly.

            Overall a great product, especially for cleaning windows quickly and efficiently, just be wary with the flaws I've stated.

              A brilliant piece of engineering that not even James Dyson would have thought of!

              ==Karcher WV50 Window Vac==

              Well, isn't window cleaning a chore! In our house it only gets done maximum three times a year, but because of two reasons, a) because it is a chore & b) because we have lots & lots of windows of all different shapes & sizes! In our house window cleaning gets done by being wiped with a cloth dipped in a bucket of Fairy Liquid, then washed down with a damp cloth, then squeegeed dry! For all of our windows, you could be there for quite a while, especially as you would need to lug two heavy buckets of water around with you! But to make the cleaning of the bigger windows a bit easier, Dad (who used to do all the window cleaning but not any more!) brought a Vileda set that consisted of a wash pad & a long squeegee on two very long poles,
              this set has made the job easier for him but still the windows are only cleaned maximum three times a year! However, this little neat bit of kit is great for the little windows around the home, inside & out! The neat bit of kit i'm talking about is of course the Karcher WV50 Window Vac!

              ==A little about the brand==

              Karcher (if you may not know) is a brand from Germany that specialises in professional & domestic cleaning equipment, also well known for their bright yellow products & pressure washers. They have been around since 1935 & make Vacuum Cleaners (Dry, Wet/Dry, & Wet), Carpet Washers, Blowers, Pressure Washers & of course, the Window Vac! They continue to develop new products to make our lives easier such as the pressure washer, that of course is useful for blasting dirt off a car, or washing decking areas, aswell as washing windows. This is just one of their brilliant products & it feels well built & feels it can go the distance. The company began when Alfred Karcher was in Germany & came along the 'Karcher Salt-Bath Furnace'. I have not idea whatsoever these were used for but seemed very popular indeed as they sold 1,200 units from 1935 to 1945. The pressure washer soon came along & this proved extremely popular with consumers & now Karcher have gone eco-friendly to the idea that now a Karcher Pressure Washer can be run off a water butt. Clever!

              ==A little about the Window Vac==

              Launched a couple of months ago lo & behold the Karcher Window Vac advert burst onto our TV screens with a man cleaning windows the traditional way whilst a woman was cleaning the same window inside using the Window Vac. The advert showed how the Window Vac user managed to do the whole window in half the time it took for the man to do it the traditional way. For the average price of £50 the Karcher Window Vac does seem expensive for what it is, but you see the price is high because you can use it for lots of other uses than just sucking water of windows. You can actually use it for removing condensation off shower doors, cars or car windows, leaving tiles squeaky clean aswell as making glass tables shine! Even (small) spills of the floor of cups of tea, red wine etc. can be picked up using the Window Vac. If you go to Karcher.co.uk & click on 'Window Vac' you will find specifications & reviews aswell as heaps of uses shown on the website (with pictures too!)

              ==Product Specifications==

              Width of Vacuum Nozzle: 280mm
              Wastewater Container contents: 100ml
              Battery Charging Time: 2 hours
              Battery Running Time: 20 minutes
              Area Cleaned per Battery Charge: 20-22 Square Feet (or approx 45 windows)
              Voltage: 220 - 240
              Weight including the Battery 0.7kg: (700g)
              Dimensions (L x W x H): 130 x 90 x 355mm
              Type of Battery: Lithium Ion

              Model Number: WV50

              As you can see the machine including a fully charged battery is only 700g so everyone can use it with no excuses! It is thin but quite tall & holds 100ml of water. Plus 2 hours charging time equals 20 minutes running time. So you will be up & running again in no time!

              ==Whats in the Box?==

              In the box you get:

              The Karcher window vac complete with water tank, battery (fully charged) Squeegee & charger.

              If you buy the Karcher Window Vac WV50 Plus you get a spray bottle which you fill with window cleaning detergent with a microfibre pad attached to it so you are able to tackle tough stains before giving the window a final wipe over with the Window Vac. My Dad bought this & he payed £37.99 from Makro (plus VAT it would be £45.59) so this is the priced he payed instead of paying £59.99 (!) from Argos or £48 from ASDA. If you can afford to pay that little for the WV50 plus, then go ahead, but the basic model is good enough for others!

              ==Performance of the Product when I tried it==

              I finally got to have a try after seeing Dad with it & let me tell you now it is so easy you wonder how you ever survived without it! I went to the sink & dipped a J-Cloth in some soapy water (washing up liquid & hot water) & wrung it out. Then I went to the window & wiped the window vigorously with the damp cloth until bubbles showed up on the window. I then grabbed the window vac & turned it on using the push button on the underside of the handle & watched as a red light flashed up. I then out the squeegee on the top of the window & pulled it down, watching in amazement as the Window Vac was sucking up all of the dirty water from my windows & it entering into the little water tank on the side of the machine. When I had finished I stood back & saw what a great job I did! I then turned my attention to the water that was sitting in the water tank, waiting to be emptied. It was filthy dirty! I knew my windows were dirty, but never that dirty! As a plus, the windows looked really clean & really, really streak free!

              Summary

              For £37.99 (or £45.59) this product is worth every penny from me! It vacuums excess water away from the windows, leaving them streak & smear free. The Window Vac is not another one of these gadgets that you 'use for a month or so & then just gets stored in the back of the shed only to be discovered in 10 years time & given away to a relative or sold on a car boot for a couple of pounds'. It's one of these gadgets that will get repeatedly used a good few times every year & maintained (e.g. that you will look after). The windows look really lovely & when the sun shines I am not afraid to let the light come through them anymore! The only couple of down sides are that the Price is heavy unless you find a good deal & the instructions are all writing (thats quite small) with no pictures & it's in about 10 different languages too! For me though this little Window Vac is great & I might even set up a Window Cleaning Business! © BrookieFan99 2012

              takes the stress from window cleaning

              I have been flicking through the freeview television channels lately and on the shopping channels they have been advertising the Karcher WV 50 Window Cleaning Vacuum, every time I see it I keep on trying to tell myself ten good reasons why I do not need to make the purchase, until one day I could no longer resist, before I made the purchase I decided to shop around online and see if I could find it any cheaper so that I could clarify that I was making the right decision making the purchase and possibly save some money at the same time. I came across one on eBay for £45, including delivery so I thought it was a bargain and I had to have it.

              If you are not an eBay fan I also came across this product with free delivery on Amazon for under £50 as well. The shopping channels were a little more expensive and also had a costly delivery, but they always have new offers, so make sure to shop around.

              Right that's enough about my purchase, what is the Karcher wv50?

              It is a new way to help clean your windows, but it does not just clean windows it also can clean glass tables, tiles, mirrors and showers really any flat dirty surface.

              The best way to describe this is it is like a light hand held mini Hoover, but with an attachment that is like a car ice scraper blade. It comes with a Battery Charger and a Lithium Ion Battery. To charge the rechargeable battery you connect the cable and once fully charged you disconnect the cable and the machine is ready to use with no cable to get in your way while your work.

              I cannot believe how quick and easy this machine is to use once it is charged I can clean a window in under a minute. With no drips and mess it can be used outside or inside the home without the fear of water going everywhere.

              How to use

              Once you have charged your unit I found that in the first charge it took about one and a half hours until the Indicator light stopped blinking to confirm that the machine was ready to use. You them with warm soapy water wipe the window or the surface you are cleaning and then take the Karcher WV50, turn it on and then run the blade of the machine across or down the window in lines, whichever you find more comfortable. The dirty water from the surface is collected by the vacuum and put into a reservoir, which you empty when you are finished.

              It takes a little practice when you first use it as you need to see if you prefer to go around the window or run down the window. I found that it was easier to run in lines down the surface as if you did the outside and then the inside there were some smears in the middle of the surface that you had to run over again. Running in straight lines means that I did not have to go over the area again at all.

              You never realise how dirty your windows are until you can compare them to other areas in the room. The dirty water that is collected in the reservoir will have you amazed and shocked as it's so dirty and black that you appreciate that you need to clean your windows more frequently.

              The Karcher makes sure that you have no streaks and perfect clean windows without the need for costly glass cleaners and cloths. This one handy tool does everything that you need, whilst making sure that your window sills are still clean and water free and that no water can run onto your floor either.

              If you have a glass table this takes all of the effort from the hours of polishing a month that you will do to keep it clean an all in a matter of minutes.

              I now not only use this on my windows and patio doors I also use it in the bathroom to clean the tiles and shower screen as it make sure there are no smears and marks left after wiping then clean.

              The booklet recommends that each charge should clean approximately 45 windows or an area which is 60m sq which is more than ample for my needs. It is compact so it is easy to store and is also light weight, weighing 700 grams so can be used by anyone of any age.

              In the box come the booklet, the window vacuum, a charger, a battery and a window cleaning head. Karcher do recommend you use their specially formulated cleaner and applicator, but I really do not think that it is necessary. There are also other products available to use with this Karcher and they are a belt to place accessories in so that are at hand while working and also a smaller blade, which would help in those smaller hard to reach areas or small top windows, which I think I will definitely be investing in, in the long term.

              I now wish I had purchased this sooner, Karcher have made the task of cleaning windows so easy it is no longer a task that I dread. As it is not a machine I use daily I have also let a few family members borrow it and they also think that it is a great invention, which does an amazing job.

              I have only one criticism and that is the reservoir that collects the water is only emptied by a small hole, I wish that it had an easier way to clean and release all of the dirty water so that it could dry out properly. I left the container draining for a few hours hoping the water would drain out before I packed it away but there was no such luck. If you do not regularly use the machine I worry the few droplets would not smell too nice when you next came to use it.

              Overall a great product that although there is an expensive outlay at the start, if you usually pay for a window cleaner once a month for £8 before the year is up you would have paid for the machine and start making some savings and have shiny clean windows. I would definitely recommend that every home should have a Karcher window cleaner in their home.
