Not surprising. I had a high pressure washer from the same brand and it self-destructed after very light use. But of course, out of the warranty period. The high-pressure part that failed was made of plastic, and it cracked badly. Not made to last, by any means. Now i have a lavor branded washer. Every high-pressure section is made of aluminum. Even the water inlet.

[@Addixxtion]

@@f-s-r I agree I have the K2 pressure washer and the high pressure plastic pipe (stupid idea!) Split, but the wonders of eBay and £5 later I've replaced it and all is well.... For now! But was an easy fix. But, as you say a non-corrosive metal sections are far superior.

You are a pro and we other are flimsy but this device is fun to do homework

[@ADominacja]

Worked in a Karcher store for 2+ years and sold a lot of these, these are really fun for window cleaning (or any smooth surfaces, really). Repairing them is another story, as there are almost no parts you can get from the manufacturer - can't get the motor, the board - just the plastics and the rubber. And while with other equipment, Karcher can be very strict when it comes to doing a warranty repair (document the damage done, the parts that you used, send the broken ones back to central), we were told at some point to just straight up replace these (though we still had to ship the broken ones to central, there was no need for detailed documentation). There are other models of this device, one appearing on the market after I've switched jobs. There is a WV5 which had a replacable (ok, EASILY replacible) battery (18650 in a case, as far as I know). There's also a WVP 10, which is a commercial-grade variant on WV5. It being 50% more expensive, I wonder whether it's any different from the WV5, as Karcher did sometimes just paint the body grey, give a warranty for commercial use and raise the price.

SO GLAD I SAW THIS VIDEO! My house has stupid wooden framed double glazing (as you would expect most panels of glass are shot) but as the the panes are also quite small and so many (yep they are a total pain to clean) I was going to buy this window vac to clean the windows that I can still see out of, but as there are so many panes, it would get quite a lot of use as not only is there a lot of small panes to clean... I live in London so the pollution muckies up the windows quickly... I can see this window vac lasting only a few months which for £50 quid isn't good at all and I don't feel like going in to Argos twice a year or wrapping up Amazon returns... I will stick with a chamois, a squeegee and a bucket!

[@Xenon777_]

I’ve had two of these. One thing I’ve learned; they don’t like suds. They are decently designed. The suction makes water enter and by gravity it enters the container and air goes the other way. If you suck up water facing it fully down water can’t enter and then it goes into the motor.

[@davetidder2085]

Have to say Clive, I've had several of these window vacs and they all give up the ghost relatively quickly. The main issue with them dying is if you don't charge them as soon as the 'blinking' LED comes on. You know. Turn it off/on again get a few minutes more! Do that too often and the voltage on the battery seems to go too low and it then will not charge back up again. I've replaced the battery with a new fully charged one and all is good. Apart from the nightmare of trying to spot weld the tabs on in the first place

[@dimitar4y]

I bought one with the same fault. There's a resistor under the connector that seems to die 100%, and it's responsible for the charge circuit. It makes the charge circuit think the battery is fully charged and it cuts out the charger. UNFORTUNATELY THE DAMN RESISTOR'S BLOWN ITS TOP AND I CAN'T READ WHAT VALUE IT WAS SUPPOSED TO BE

[@SciDOCMBC]

As a German I feel personally offended by Clive's pronunciation of "Kärcher" 🤣🤣🤣 Really you're simply the best Clive.

[@kevvywevvywoo]

these get water in when people move them away from the vertical. Its tempting to turn them round to get into the lower corners but then the motor sucks the water up and sprays it around inside and out through the vent. Similar effect putting it down on the lawn full of water and it gets kicked or tipped over. Mine's years old and I've never got water in it. Still works like new. The micro is involved in the charging BTW, the LED flashes quickly as its charging, steady when its full, and flashes slowly to say it needs recharging soon . Once the battery is exhausted the motor turns completely off.

[@waldevv]

Ah yes I have one of these, it's actually quite handy for drying off a lot of surfaces, not necessarily just windows Nice to see how they're built without taking mine apart I'm guessing it was stored on it's side or something instead of leaving it straight up? Haven't gotten to the conclusion yet but that would be my guess

Same happened to mine, people using them sideways when the water bottle is full means water pours inside and corrodes the battery, its such a known fault they have crates of them on couriers, when I had mine delivered there was a box with about 100 of them in, they have to change them all the time I have friends that work for the company here in my home town, its a great device but you have to use it in the vertical position and never take it over 45 degrees unless you waterproof the battery and electronics.

[@mbaker335]

I had one of these that failed and after finding the pump/circuit board swimming with water still brought another one. The key thing is to only use it vertically and never let the water go above the 'full' line. Never leave the reservoir with water in it and store in a dry place. A stupid non draining design. Unfortunately it performs better than others I have tried. The electronics should be potted and in the handle with two long wires going to the motor, then have a pair of holes in the bottom. As is it is designed to fail.

[@Derundurel]

I had a look at one of these recently. As with this one, water had got in. This seemed to be all that was preventing the battery from charging. All that was required to make it charge was to dry it out. Unfortunately, the water had corroded the front of the motor so much that there as about 1mm of play at that end of the spindle. It did work despite this, but I doubt it will be useful for very long.

[@ericwolff6059]

We have another, cheaper brand of one of these specifically to remove heavy condensation from our windows in autumn/winter. The mould on the window ledges and net curtains caused by the puddles was getting too much to cope with. This happens in the standard New Zealand house built prior to the 1990's, (when new building regulations meant all houses had to be built with insulation and double glazing.). Imagine, if you will, a minus five degree frost outside and having five degrees inside the house. Electricity isn't cheap, so you watch TV in the lounge, sitting in a sleeping bag to keep warm, whilst having a dehumidifier running to help prevent the condensation. Using a heater is an option, but a costly one. We do use the air con/heat pump sometimes when absolutely necessary though.

Consumer jet washers are almost impossible to reassemble - assembly jigs. They really try to prevent you from modifying and repairing them, and it is the same with things like this.

As others have concluded you need to take the head off and the bottle out and let it dry like that every time after use. They are worth looking after though, and that one is defo worth repairing! Mine has a red LED just above the charger port that indicates charging; it flashes if the battery is very low and trickle charging; steady on main charge. Maybe its a later model?

[@paulmcdonough9595]

These have become a bit of a pet hate of mine, despite being very handy to clean down my shower. I am on my second unit having hacked my first one to get around the on board start circuit which failed and the second one has now failed too. Both of mine stopped charging and even though I can charge them manually i.e. not relying on the Karcher charge circuit it has now failed to run at all. The PCB is very susceptible to water ingress and presumably this causes formation of conductive solids to accumulate around the IC legs which cause it to malfunction, no amount of flushing with solvents has fixed either of mine. If they properly dipped the pcbs they might last a bit longer. When I can be bothered to open the second one up again, it has a better fan mech and thus is more worthwhile to fix, I might fit a standard on/off switch and use a bigger possibly remote battery. Hey maybe I can make use of some of my growing collection of recovered from the gutter Vap Li Ion batteries. :0)

Our other one is the original model, years old, and apart from the odd growl from the motor when you switch it off, it's still going strong.

A way to 'improvise' these multi bit drivers: Buy longer bits, that are designed for quick disconnect. Mostly uses in drills.
