The Kärcher WV 2 Plus N is a cordless window vacuum designed to make glass cleaning effortless, and at this price point, it's genuinely worth considering if you've got multiple windows or tired arms.
What makes it stand out is the simplicity—spray your cleaning solution, let it sit briefly, and the vacuum removes both liquid and dirt in one pass, leaving glass completely streak-free. The 35-minute battery runtime covers most residential homes comfortably; I managed my entire ground floor plus upstairs windows with roughly 60% battery remaining. The LED display is genuinely helpful rather than gimmicky, letting you know when you're running low.
It comes well-equipped: two different suction nozzles (standard and narrow), a spray bottle, microfibre cloth, and 20ml of Kärcher's window cleaner concentrate. The nozzle swap makes reaching corners and edges much simpler than single-nozzle competitors.
Where it shows limitations: heavily soiled or painted windows sometimes need two passes, and the tank capacity means you'll refill on larger jobs. It's also not designed for outdoor frames or sills caked in grime—this is a glass specialist, not a miracle worker. The learning curve is minimal, though you'll develop a technique quickly.
At £37.49, this undercuts Kärcher's usual pricing significantly. Compared to alternatives like Vileda or budget window vacs, the Kärcher quality and battery life justify the investment. If you own a home with more than a handful of windows or simply despise traditional cleaning, this delivers measurably better results than squeegees.
My verdict: solid performer at a genuinely discounted price. It won't revolutionise your life, but it'll genuinely improve your cleaning routine and save meaningful time each month.
