Kärcher WV 5 Premium Window Vac

Four years ago I saw Kärcher’s earliest entry into the Window Cleaning market the WV 50. So here is the 2017 version unusually with a lower number than the original at WV 5. This is the top of the range of the three currently available units.

The cleaning unit has a 28cm wide head and all liquid it comes into contact with is sucked into the internal bottle so when you clean your windows you get results as good as the professionals with no streaks and best of all no wet arms.

The unit is 31cm tall and a maximum of 8cm wide.

The Kärcher yellow colour is predominate apart from the odd bit of black and the see through waste water container.

Included in the kit are accessories a squirt container for those internal windows and a sachet of cleaning fluid which with added water gives enough to fill the squirt container.

Also in the box is a towelling strip that can fit over the rubber edge of the cleaning arm a 13amp power plug and lead to charge the internal battery and for those smaller window panes a smaller cleaning head at 17cm.

Exactly what the parts are called is anyone’s guess as all the instructions consist of is an A3 sheet made up of diagrams and part numbers.

From the diagrams I can make out that a full recharge of the internal battery takes 185 minutes and this gives you 35 minutes of continuous cleaning. The waste water bottle holds 100ml of liquid and the sound of the cleaner catching all the liquid is 50db although if I was guessing the sound volume I would have said a lot less than 50db.

When cleaning badly soiled outside windows I tended to use a solution of washing up liquid and a cloth first as a regular windows cleaner I do not have, once I got the windows more respectable then a quick once over with the Window Vac got them pristine.

For the inside of my kitchen window with the output from a tumble dryer as well as cooking grime I also initially used washing up liquid in water to remove the grime before a quick once over with the Karcher Vac to get a good finish.

My - somewhat lame - excuse is that the Kitchen window has a wide sill that gets cluttered with a lot of items that requires me to remove them before cleaning from a pair of steps to get over the sink and draining board.

The hard work was in the removal of the clutter and fetching the steps, a small bowl of warm water and washing up liquid soon found the window looking much better but of course full of streaks that would normally be hard to get rid of but a once over with the Karcher Vac on a now clean surface soon got things pristine.

There are another couple of attachments that diagrams on the box say should go on to the squirt bottle and when I discovered what they were and where they should go – no thanks to the instruction diagrams - I tried them but I preferred to squirt diluted liquid direct onto the windows. A better explanation is found on the second link, I can see that in hot weather you would need to be quick to apply the Vac before the surface dries but that is not a problem at the tail end of the winter.

The Kärcher WV5 Window Vac is available from Amazon for £64.79 with free delivery.
