Karcher WV2 Premium Window Vacuum Cleaner Review


The Karcher Wv2 Premium 2nd Generation Window Vac is an update and improved version of the bestselling Karcher WV50.  The new model is 10% shorter and fractionally lighter than the original vac.

It now has an increased running time from 20 to 25 minutes.  In addition, the motor is a little quieter.  There is now a green light with the on/off switch which flashes when the power is about to run out so that you can prepare to finish your current task. Finally, there is an improved design to the plug for the tank.

The WV2 works by sucking your window surfaces completely dry leaving them streak free. Therefore, it leaves your windows, clear with no streaking. You can also use it for removing moving condensation from windows, mirrors, shower screens and tiles.  Finally, you can use it for sucking up liquid spills from the floor and off other smooth surfaces.

Karcher WV2 Premium 2nd Generation Description and Features

How does it Work

It is really just a squeegee with a handheld vacuum cleaner attached to it. The squeegee is in two parts and the water sucks up from the middle into the vacuum.

The rubber in the blade glides easily across the window and gives a good edge to clean and remove the water from the window.

The water collects in the plastic container and you can get rid of this later.

Using the Washer

When you take it out it the box there is two parts the vacuum and the head, these both clip together. In addition, there is a charger, which you plug into the wall. This charges the battery pack, built into the vacuum. Once you have charged up you are ready to go. The charging light is on the handle front and is part of the on/off switch. In the previous version, the switch situated on the inside of the handle, which meant that when you picked up the Vac it automatically turned on.

Does it Leave Lines

If you find that, the blade leaves streaks. Make sure that that the blade is clean.  As anything left on the blade will cause streaks. Also, make sure you are not exerting too much pressure on the blades as this can cause streaking. If you do find there is streaking you can always wipe them away with a microfibre cloth.

You can use it to clean condensation off your windows.  Generally, it does not leave any smear marks.  Use it to clean car windscreens once you have most of the dirt off use. You can use it to remove excess water.

Cleaning Condensation

A good tip is to top up the battery over night to allow you to clear the condensation from the windows in the morning. It will leave the windows completely dry and free of condensation.  Easy to use and up you can use it at all angles on the window

You can the top up the charge throughout the day for any extra jobs.

It is useful to use in bathrooms to remove excess condensation after showers and baths. Use it to remove excess water from shower screens and bathroom tiles particularly where there is poor extraction of the water vapour.  Also, use it on windows without double-glazing which suffer from condensation.

Use it on bathroom tiles, as it is much better to use than drying the tiles by hand.

What Surfaces does it work on

It only works on smooth surfaces like glass this is so the suction can work properly.

Charger

The vac comes with a charger. While charging the light on the charger flashes, once fully charged this light stops flashing.

Attachments

You can buy various accessories like an attachment for it like one for narrow windows and a dispenser for cleaning fluid.

Differences between WV2 and WV2 Premium 2nd Generation Window Vacuum Cleaner

The WV2 Premium differs from the WV2 in that the WV2 package comes with the WV2 Window Vac and a Wide Suction Head.  The WV2 Premium comes with these but in addition, the box contains a Narrow Suction Head, Spray Bottle, Microfibre Cleaning Head and Window Cleaning Concentrate.

The narrower suction head is only 1700mm wide will clean smaller windows such as Georgian windows.

With the WV2 Premium, you can clean the window before using the Window Vac. You fill the spray bottle with the window cleaning detergent.  Then run the wiper attachment with microfibre head down the window.  You then wipe over the window using the Vac and the dirty water collects in the reservoir.

What I like about the Karcher WV2 Premium

 2nd Generation Window Vac Performance

  • The Window Vac is lightweight and compactly designed.
  • It makes window cleaning a lot easier and faster to do.
  • It is a fast and efficient way of drying windows and other surfaces
  • It leaves no streaks and you can clean up to 75 square metres of glass one charge of the vac.

What I dislike about the Karcher WV2 Premium

 2nd Generation Window Vac Performance

  • Only approximately a third of the surface of the head actually sucks the water up, this is the part near the centre of the head.  This means that water can drip from the edges as you are cleaning.
  • The old accessories from the previous model WV50 do not fit this new model.
  • The reservoir for the water is rather small so you do have to empty it more frequently.
  • It is a bit fiddly to empty and clean it.
  • It takes a little time to charge but once charged runs for a good time.
  • With the WV2 Premium there are two squeegees an ordinary sized one and a narrower one for smaller windows.  However, the spray bottle only comes with one wiper attachment.  Therefore, you cannot use the wiper attachment on smaller windows.  In addition, you can only use the spray vertically otherwise; the detergent comes out of the bottle.

Mine has died after only a few uses! No green light at all and won’t charge. People have suggested I need a new battery but this doesn’t seem to be available. Please can you help?
