Kärcher - Window Vac WV 5 Plus

Winter mornings in a poorly ventilated kitchen or bathroom can leave window frames and tiles dripping with condensation, and a cloth just moves the moisture around rather than removing it. The Kärcher WV 5 Plus works by vacuuming the water directly off the surface into a small onboard tank, leaving glass and tiles genuinely dry in a single pass. What separates this model from the cheaper WV 2 is the edge guidance system — a physical channel built into the suction head that locks against window frames and lets you clean right into the corners without leaving a wet strip behind.

Who Is This For?

This is for anyone who battles persistent condensation on double-glazed windows, shower screens, or bathroom tiles and is tired of the damp cloth cycle that breeds mildew on the sill. It also earns its place after cleaning glass with a squeegee or spray, removing the last of the cleaning solution streak-free. If you only want to clean one window occasionally, a decent microfibre cloth is still fine — the WV 5 Plus makes the most sense where there's regular, recurring moisture to deal with across multiple surfaces.

What Buyers Say

Owners consistently praise the suction power and the noticeable upgrade the edge guide provides over previous Kärcher window vac models. The battery life — rated at around 35 minutes — draws the most grumbles, with users doing larger conservatories or multiple rooms finding themselves waiting for a recharge mid-job. The tank is also fairly small, requiring emptying every few windows if condensation is heavy.
