Karcher WV50 Window Vacuum Questions & Answers
It is leaving windows and f oors streaky
Hi there, if it's anything like my WV50 - which we use for the shower - you'll find that it clogs up after some time and needs to be cleaned out. I've created a video that shows you how to open the head of the unit and clean out any obstructions.
In our case as we use it for the shower, it tends to get clogged with hair, shampoo and conditioner. You may well find that as you use yours for floors that there is also a similar problem.
All the best and I hope the video helps.
Why won't it switch off?
Because the switch is broken and stuck in the "on" position. Until you fix it all you can do is plug it in and out for operation. If you are handy you can take the switch out, make the repair of the broken part, and reuse.
They wanted 35 dollars for the switch on my Karcher power washer. Yeah, right!
It keeps dying even after being charged.
You need a new battery. I could describe how to rebuild the old one if you are so inclined to do that type of thing. It would save you some money over buying a new one. It looks like it is a specialized piece of cleaning equipment and buying a replacement battery would be fairly expensive.
Where's the serial number on the karcher WV window vacuum
Hi. I've just bought the karcher window vac wv50 & am having the same problem finding the serial No. I presume you want to register your product for the guarantee to be valid. I went online Karcher.co.uk & registered mine. You will note that when doing so it does not ask for a serial number but a model No. This is found on the side of box you got the item in (mine is just above the barcode) & it reads something like; 1.633-113.0. Hope you still have the box!
Cant charge it the red light blinks fast when i push power button
I had the same problem but discovered on opening up the unit that the motor was a bit stiff to turn. I therefore prised off the fan and removed the waterproof shroud only to discover some corrosion on the front bearing. A drop of WD40 did the job and now its working again good as new.

Replace the switch! It shut down when battery get depleted. and then when you start it again the cycle is shorter because the batery regenerate but not as previous cycle.
Will not turn off
I had the same issue and after much exploring I discovered just a tiny bit of corrosion in the switch. To repair, remove the squegee section, and water bottle, so you just have the base unit. Then remove the bottom plastic cover and unfasten all the screws. Now remove the switch. With a fine Exacto knife and a magnifyer remove the switch and open it. Check it for corrosion this is whats causing it to stay on. Carefully scrape out the corrosion with the Exacto tool and then carefully reassemble. The light should switch off. You can also test it before reassembly just to make sure all the corrosion is gone.
Can't switch Karcher window vac off
I had the same problem and I let the battery run down to stop it cycling on and off. My husband investigated it and found that there is a fault with the on board battery charge sensing circuit. (when the charge is about 10 to 15 % remaining the onboard ic controller cycles the unit on and off, irrespective of the switch. He checked it by cutting wires to the switch and it still cycled off and on so the switch was not faulty.
He put it all back together and said to charge it before it gets too low. If it cycles on and off it probably needs a re charge at that point.
Unfortunately there is no battery level indicator on the tool and nothing to suggest in the manual of what may happen when battery is flattening.
I am taking this up with Karcher as I only used it three times so far and it it was not a cheap gadget. Hope this helps
