Kärcher - Window Vac WV 2 Plus N

Condensation on windows is one of those mundane household problems that quietly causes real damage — mould around frames, water-stained sills, ruined paintwork — and a squeegee and cloth typically just pushes the moisture around rather than removing it. The Kärcher WV 2 Plus N works differently: it vacuums the water directly off the surface and into a small onboard tank, leaving glass dry in a single pass. The inclusion of the narrow 170mm suction nozzle with this model is a meaningful detail, letting it reach into the tighter panes found on older sash windows, shower screens, and conservatory glazing bars where a standard head simply won't fit.

Who Is This For?

This is a practical buy for anyone dealing with persistent morning condensation, particularly in flats, older houses with single glazing, or homes with a bathroom lacking adequate ventilation. It earns its place in kitchens and shower enclosures too, where daily moisture build-up is a mould risk rather than just an annoyance. If you're only cleaning windows once a month on a dry day, a good squeegee and microfibre cloth will serve you just as well for a fraction of the cost — this tool rewards daily or near-daily use.

What Buyers Say

Owners consistently praise how quickly the WV 2 Plus N clears a full window without streaking, and the battery life is generally considered adequate for a typical room. The most common grumble is the small dirty-water tank, which needs emptying more frequently than you'd expect on larger jobs like conservatory roofs or big shower enclosures — a minor but genuine interruption to the workflow.
