Kärcher - Window Vac WV 6 Plus

Condensation on bedroom windows in winter is one of those daily irritants that a cloth just smears around — the Kärcher WV 6 Plus exists specifically to solve that. It vacuums the water directly off the glass rather than redistributing it, leaving a streak-free surface in a single pass. That same principle works on shower screens, tiles, and mirrors, making it genuinely more versatile than its "window vac" label suggests. The rechargeable battery gives around 35 minutes of runtime, which is enough to cover most households in one charge cycle.

Who Is This For?

This is a strong buy for anyone in a home prone to condensation — think older properties, poorly ventilated bathrooms, or houses where drying laundry indoors is a winter reality. It's also well-suited to people who have large glazed areas, bi-fold doors, or conservatories where streak-free results actually matter visually. If you're considering this purely for an occasional wipe-down of one small bathroom mirror, a decent squeegee will serve you just as well for a fraction of the cost.

What Buyers Say

Owners of the WV 6 Plus consistently praise the improved suction over earlier Kärcher window vac models, and the wider blade attachment is frequently highlighted as a time-saver on larger panes. The extended battery life relative to the WV 5 is well-regarded. The most common gripe is the water collection tank filling quickly during heavy condensation sessions, requiring frequent emptying — not a dealbreaker, but worth knowing if you're planning to tackle a conservatory in one go.
