Can live without it – Intended to use this to clean the glass pool fencing however upon using it still causes streaks, so I would still have to manually wipe away the streaks. Might as well do it the old fashioned way and get a better result. Used it to clean the shower glass doors as well and no problem there, but I don’t need to clean the shower doors everyday. Have only used it a handful of times and can say we could definitely live without it.
Purchased in at The Good Guys.
Must of got a dud! Terrible! – I was so excited to use this product as I had just recently installed double glazing, followed all the instructions, the windows were full of streaks, I was so disappointed. Took 3 hours to charge the appliance. Received far better results with newspaper and Windex, dont waste your money!
Purchased in at Bunnings Warehouse for $119.
The vacuum device is brilliant fabulous works perfectly and I can’t live without it because I have so many large windows. The new improved washer solution bottle is better because it doesn’t instantly fall over like the last one but annoyingly it doesn’t have enough capacity. When I buy another one in ten years when I buy my third one please… Read more · 1
address that issue! Otherwise apart from that it’s fantastic. The charger died on the last one but the machine still works perfectly and charges with the new charger.
I used once, the product stopped working, got a replacement sent out and same thing happened again and now I cannot get a response from Karcher to my emails for a repair or replacement. Show details

First of all, the charging time is good. It was fully charged in few minutes. I've used it in 3 of our wet areas and I'm super impressed how the work time drastically became lesser. With the normal squeegee, I still need to wipe every time I wipe at the glass but with the vacuum feature, it makes everything so easy. The cleaning formula is so… Read more · 1
effective too, I cleaned in one go. I'm super impressed and this is a life changing product. Now I'm curious with other Karcher range.
Outstanding little machine – After a bit of discussion my husband recently purchased the WV6 window vac for me. It was quite expensive but we do need to pay extra for products where we live. I think it was $345 At first I was a little disappointed with the machine, until I figured out how to use it properly. I was putting too much pressure on the machine and wasn't using… Read more · 1
enough water. Boy have I got it down pat now. We live by the beach, so you can imagine how often I need to clean windows, plus we use it at work. We cannot buy the Karcher cleaning solution on island so I improvise with a small drop of dish washing liquid. You can use vinegar also. To make my life easier again, I do not use the spray bottle with microfibre cloth that comes with the machine. I purchased a "weed sprayer" pressure bottle and use a window brush on a pole. First spray the windows, scrub with window brush then give the window another light spray. Now the fun part. I get out my WV6 window vac and without putting any pressure, I lightly vac the window, holding the entire vac as straight and as close as I can to the window. Whalah - magnificent windows. I love love love this machine and would highly recommend to anyone. PS - I do the exact same method inside, but lay down a towel (not that you really need to)
It CLEANS windows – Read various good/bad reviews on Karcher but decided to take the plunge and bought it in December 2021, WOW what a great job it does. Wet the filthy glass first then apply the window solution and rub over with applicator, next used the Window Vac and voila! - super clean windows, no streaks, LOVE IT! Show details

Actually, this a WV2 Black Edition – No idea what the Black Edition refers to ? Bought it at Bunnings along with an extension pole set + Glass Cleaner, total of $209, as a Christmas present for my wife, just kidding !! ##THIS is NOT a steam cleaner, by the way. The glass cleaner solution is really good. Pole set a bit fiddley but gives just enough reach for most of our glass.… Read more
Resevoir capacity more than adequate. Needs some practice to get best results & cannot reach bottom of the glass if you have floor to ceiling as the unit itself gets in the way. Need the extension for the high parts but have to remove unit from pole to complete the lower part, no big deal. However, need to do a horizontal sweep at the end. Instructions are pretty rubbish but my wife deciphered them. Spray bottle needs a better feed tube or at least adjust it as cannot use the last of the fluid. Can see many uses for it, but, wish there was something for louvres ? Unit "assembled" in Lithuania & poles in Italy, no info given on hardware provenance. Registering purchase with Karcher is terrible, they want loads of personal data so I put a false DOB (security/data protection) & then upload the invoice, which did not work. Gave up on the whole process, total farce for such a simple purchase. Sent a missive to Customer Service, do not expect a reply.
Mostly pleased but definitely overpriced – Have a problem with heavy condensation on the inside of my windows and been looking for a solution. Came across this when looking for something else and thought be worth a shot, tried everything else without too much luck. The tiny bottle of cleaning fluid was ... well tiny. For something in this price range, was disappointed. It does give a good… Read more · 1
clean though and would buy a full sized bottle.
While it doesn't give you the amazing results it claims unless you have a perfectly clean surface to begin with, an ideal angle to work with and a very steady hand, it is not terrible either.
That said, it works pretty good well for what I need. It sucks up all the condensation on my windows nicely, and leaves them much cleaner than I have ever managed to get them, My windows go to the just above the floor though and this thing can't quite tilt up enough so you get a little mess near the bottom. I am not especially worried about it though, as it is more than good enough for what I want.
Did do a pretty good job on my bathroom mirror and shower screen, which was at all the right angles. Also got my fridge door the cleanest I have ever managed to get it.
It is tricky to use though, and a streak free finish is a bit of overpromise. Am a little disappointed because of the price point, but otherwise reasonably happy with it. The battery lasts a good while on one charge and it doesn't have a base that takes up room, just plug straight into the unit. However it is one of those monumentally stupid plugs that takes up more than one spot because it is on the side, so you have to plug it into the end or you lose at least spot on your power board or wall plug.
Is light enough for me to handle it without any problems. The spray bottle sponge thing comes in pretty handy too for all kinds of surfaces, like my stove top and comes off easily enough to clean. The water tank is small but not too small to be impractical, just need to empty on regular basis, and make sure the 'blade' is clean, it has a tendency to hang onto things like hair, which causes streaks.
If you have the budget and your expectations are not too high, then this is worthwhile. If you are wanting that perfect finish without fluffing around to sort out the bits at the end, then wouldn't recommend.
Not as advertised – I bought the WV 6 + KV 4 Bundle. I was hoping for great things, unfortunately it was NOT to be. I thought I would give it a good test to start with, so I attempted to clean the shower glass. I used the KV4 first, it cleaned ok but when I got to the bottom where all the body fats and soap scum reside it couldn’t get through it. Looks like Jiff, a… Read more
scrubbing brush and elbow grease are the only way to remove that stubborn stain.
Then I used the WV6, as I scraped from the top of the screen down it grabbed the dust that sits on the top edge of the glass and the whole thing went bad. So, I wiped the top of the glass with a cloth and tried again. The machine does NOT go all the way down the bottom and I had to go horizontal at the bottom to get that bit.
It did a good job, the glass looked clean enough and better than before but if you are a neat freak like me or maybe selling your property and want the glass perfect then you will be disappointed. After doing both sides and looking at it from different angles you can see the streak marks and the bits that are NOT clean.
If you get any foreign material (dust/dirt/hair) on the squeegee part you have to remove said foreign materials from the surface, clean the squeegee head and start again.
Next, I tried the round bathroom mirror. Same story. Then I tried the square ensuite vanity mirrors, once again same story. I actually had to get a cloth to wipe them once I had finished to get rid of the streaks and marks let behind. As with the square shower glass the squeegee doesn’t leave the edge streak free.
I am stuck with the products now, so I’ll keep them and use them for spills clean up.
I like the Karcher brand and have had a pressure washer from them for 7 years now, just broke down and I bought another one as well as the WV 6 + KV 4 Bundle. I thought I would give it a go but unfortunately it does NOT do as advertised.
Save your $260+ dollars, get a bag of cheap cloths and some good window cleaner, you will be better off.
In fact after I used it that day, it's been in the cupboard ever since, such a waste, ooh well you live and learn.

The machine was easy to use, charged quickly and worked well. I found it was great on windows and glass doors but on my shower screen it looked like there was no streaks but as soon as the shower got hot and steamy you could see all the streaks that were left behind. It’s a bit expensive for what it is. Show reply
Window cleaning has never been so easy – I can’t believe I didn’t by this product earlier. Its simplicity of use is impeccable. I cleaned every inside window and sliding door with complete ease, not only that battery still had plenty of power. I also used it on the windows and sliding doors outside. One tip I’d pass on is using a soft brush and bucket of water when cleaning outside to… Read more · 1
remove bird poo and other heavier soiling first, then using the karcher to get a pristinely clean window/door. I read the reviews saying it leaves streaks, it does not. Obviously it’s not being used correctly.

Good vacuum – My Karcher WV5 gave up running so I replaced it with a Karcher WV6+KV4 vacuum and washer. The vacuum works really well and I can actually get to the bottom of windows and doors. However the vibrating washer I consider extremely poor. It doesn’t put out enough water for the vacuum to suck up which leaves a streaky result. I now use my original bottle washer with the WV6 vacuum and have great results. Show details · 1

Junk cleaner – This cleaner failed. Not sure why. Have YouTubed possible fixes but still will not go. It's out of warranty so can't get it repaired for no cost. So it's in the bin and I will never buy a Karcher product again
Karcher window cleaner is a expensive squeegee – I had thought the cleaning drying process was more sophisticated than using a hand held window cleaner with a squeegee with no streaks. Sad to say its just a hand held cleaner tool and a squeegee. Only benefit is the removal of water when doing inside windows. It is definitely not streak free. It is great on the shower screen. Windows not so much. Have used it 6 times on my glass doors and no improvement. Show details
Disappointing – I purchased this only a couple of days ago and tried it on all my doors and windows. Was very disappointed in the result. As others have said - a very expensive squeeze! Let streaks on all doors and windows and I had to use a cloth to go over them all to remove the streaks. This is what I was trying to avoid! Show details

I was surprised by how light the machine is and how easy it is now for me to clean my windows. The machine is fabulous and what I loved more is their customer service care. Amazon did not deliver all the parts advertised on their website and I realised it a couple of months later. I contacted Karcher Australia and they were able to assist and… Read more · 1
shipped the missing parts to me. The service care team was very prompt in their response and I got the parts delivered to my address in less than a week. I will certainly purchase more of their products in the future. I highly recommend WV5 window Vac.
Save Your Money+ – 2nd Karcher has died within warranty period but I have been told the 2nd one doesn't have the 2 year warranty as the warranty starts from the first one purchased! I queried why the battery dies so quickly and was told it is a lithium battery and it only lasts so many charges and then will no longer work! Really annoyed as it was so easy cleaning windows, shower etc when it did work! Show details
Stopped working after using three times – Worked well for the first three times then went to charge, no charge. Rang Harvey Norman and was told it was just out of warranty. Waste of $119. Show details
Quick but streaky – This window vac is faster and more enjoyable than cleaning my windows and mirrors the traditional way. But it is very streaky, even after following YouTube videos on how to avoid this. Definitely still need a cloth for a perfect finish. Also, I wish the dirty water tank was detachable so it could be rinsed out properly, but it is attached to the… Read more
motorised unit. As a result, the tank is never quite empty/clean.
Overall, I'm still happy with this purchase and glad I didn't get a dearer model.

3rd fail! – This is the 3rd Karcher window vac I've owned and this one will be going back to Bunnings tomorrow. The motor no longer works and it's only 6 months. Exactly the same problem I had twice before. A shame because I like the efficient way it cleans the shower screens. Show details

Great until it stopped working – Purchased a WV2 Black edition and in the first year I would have given it 5 stars. Used about 6 times. But now it will not work. I can get the green light to flash for a small period of time when on charge than nothing. Silence!!!! Completely dead. Show details

Not worth the time or the cost! – The Karcher window vac is pretty much just a gimmick.... a total waste of $100 Takes just as much effort as old style cleaning but no better outcome. Don't waste your $ Show details
It does work but – It works as well as a bucket of water and normal squeegee. I doesn't do away with streaks but then the "normal " method of a squeegee can leave streaks. The greatest advantage is all the dirty water is collected and not spattered on the floor. I cannot use it inside because I have Stegbar Comfort plus glass and I am concerned it could damage the… Read more
inside coating. I have only used it three times on the outside of the windows and I usually combine cleaning the windows with washing the tiles on the verandah. I still have to wash the window frames separately so I still end up with a bucket and a wash cloth. It does save a little time. I have had it about 12 months and now the charger doesn't work. I cannot be bothered to go through a warranty claim so it will go in the bin and I will go back to the old squeegee.
Perfect windows – I bought this appliance from Bunnings and it is fantastic. Easy to use, light weight, easy to store. Cleaning windows has always been a chore for me, something I would only do when absolutely necessary, but now, voila, my windows are bright and shiny. Also the shower recess has never looked so good. The cost was $179.00. Every household should have this appliance. Show reply
Game changer – I love it! I use it on windows, to clean the shower, all the mirrors in the house, my gloss kitchen cupboards. Don’t have to refill the water tank to often and it’s super quick to use. Would recommend having a window cloth as it does sometimes leave lines and this just finishes it off. Show 2 replies
Worked great till it didn't – Had the unit for over a year. Probably used it 10-15 times. Now it's dead and Won't turn on despite the battery being fully charged. Don't waste your money....just don't. Show details

Good concept let down by a total lack of reliability – This is a good concept and when they work you get a good result. However, I cannot recommend this product due to its poor quality. I have purchased two (an original and a premium when the first died, hoping that this was an aberration). They work, then they don't. The first lasted about 18 months with a reasonable amount of use and then would not… Read more
switch on, due to what I a suspect to battery failure due to its refusal to charge, even when left on the charger all day. The second suffered exactly the same fate, again after very moderate use and after the warranty had expired. I have a number of rechargeable appliances (cordless vacs, chainsaws etc) that have given years of faultless service so I can't understand how a company with Karcher's supposed reputation can market such an unreliable product.

Waste of money – My experience of this product left me feeling like a fool for spending $200 on what’s basically a battery operated squeegee. Unfortunately I can’t find anything positive to say about it. I tried it on my pool glass. Did nothing. Tried it on a window. Nothing. I gave it one last try on the shower recess. Hopeless. It’s too big and bulky to… Read more
use in a single shower recess.
I’ve used far more effective glass cleaners to, and as I said basically all you’re getting is a battery operated squeegee. Cannot recommend this product. I returned it and the glass cleaner for a refund.

Good when it works – The machine worked well for the first 6-months of purchase. Cleaning windows, with ease, as promised. Unfortunately it stopped working, and Karcher customer service was not supportive in rectifying it, even though it was under warranty. It took many attempts to get acknowledged, and when I did, it was unreasonable on the solution. I leave in… Read more
the inner city of Sydney, and they wanted me to a go to a suburb an hour away to drop off the product. Get it evaluated, and possibly fixed, which then involve me going back out to the same suburb - no option in shipping it there, or back to me. For a product I spend $120 on, not huge money, but the time off work, and cost of renting a hire car, twice, not worth it. It is unfortunate my experience of the product was so tarnished.
Great results initially but unit will no longer charge – This is my second window vac from Karcher in 2 years. I was so impressed by the results initially however after less than 12 months the unit would no longer charge. I contacted Karcher & was advised to return to my place of purchase which I did & was issued with a replacement. Unfortunately less than 12 months later the same thing has happened… Read more
however I cannot return this unit.
I am extremely disappointed as there is obviously a known issue with this model!!!!!!
DO NOT BUY!!!!!!!
Total rubbish – Purchased window cleaner because of brand name. Biggest piece of rubbish. More streaks than anything used before. Do not buy this device. It is a disgrace they sell it. I purchased it at bunnings. They told me they had so many bad comments about this thing. Karcher. Take your name off it and sell it back to wherever it came from Show details
