About the Kärcher WV5 Window Vac

The WV5 Premium is the latest in the series of rechargeable window vacuums by Kärcher.

It comes with a spray bottle for dispensing the detergent solution, a microfibre cleaning head to rub the detergent on the dirty surface, detergent and two blades.

The product has everything that you need to get started and is also very easy to use. You have to start off by pouring the detergent and some water into the spray bottle.

After this, spray the surface to be cleaned with the spray bottle and rub the liquid over it with the provided microfibre cloth. The last step is using the vacuum to clean the detergent solution off the window (or any other surface) to reveal a shiny clean exterior.

As compared to Kärcher’s older models, the WV5 Premium comes with a 25% increase in battery life. The newer version this window vacuum cleaner has been designed to further cut down on cleaning time. It also comes with a three-step LED display, which is located on the screen handle.


Kärcher Window Vac WV5 Exchangeable Battery Review

While the window vacuum is a little on the expensive side, it does come with a good range of features. Continue reading to know more on that!

Removable Battery

The Kärcher WV5 Premium comes with a removable lithium-ion battery that lets you get on with the cleaning in one sitting without any interruptions or sudden breaks.

After one complete charge, it can be used to clean surfaces up to 105 m² or 35 windows. There is also an optional second battery.

Interchangeable Suction Nozzle

The product gives you great flexibility in the process of cleaning with two nozzles – one large and one small.

If you have smaller surfaces, pick up the small nozzle attachment and if the windows are big, the larger suction nozzle can be used.

Easier for Window Edges

A major problem that I face while cleaning windows with gadgets is reaching the edges. The Kärcher WV5 Premium, however, comes with manually adjustable edge guides that allow for much better results.

So no more stress about missing a spot in that corner anymore!

What We Liked

  • The handle is very easy to use because of the soft grip. So, if you have a lot of windows and surfaces to be cleaned, your hands will not be sore in the end.
  • The battery level indicator is a boon! With three LEDs indicating the current battery status, you always know approximately how much running time you have left.
  • It works its magic with minimal sound. While Kärcher’s products are usually not very loud, the WV5 Premium is 10% quieter than the previous models.
  • Kärcher’s name is well known in the industry so you can be reassured that you will receive the best quality product.
  • The Kärcher WV5 Premium offers a good range of attachments. The spray bottle, combined with the microfibre cleaning head and the main vacuum, make a great team.
  • A wide range of surfaces can be cleaned – it is not limited to just your windows.

What We Didn’t Like

  • The price may be on the higher side if you’re looking for a cheaper option to get rid of your cleaning woes.
  • It is not completely streak-free, especially in the initial few times that you use the product. The problem usually arises when you don’t wet the surface enough. The process becomes smoother with use.
  • Charging can be a bit of a hassle if you’re not very regular with such things. You will need to charge it for 185 minutes if you want the complete 35 minutes of running time that the product offers.
  • The instructions that come with the WV5 Premium are limited. If you want a more in-depth look into the functioning and how it can be utilized in different ways, you may be a little disappointed. However, there are an abundance of videos online that show the best ways to use it, so all is not lost.

Karcher WV5 Review: Final Thoughts

The Kärcher WV5 Premium may be a little on the higher side when it comes to price, but it is worth the investment if you are going to be cleaning your windows regularly. It is easy to use and gets the job done quickly.

Kärcher is one of the best players in the field, so you cannot go wrong with investing in their patented blade technology. If it fits your budget, it is worth the money spent!
