Kärcher - Window Vac WV 5 Plus

Condensation on windows is one of those mundane household problems that causes real damage over time — warped frames, mould on sills, ruined paintwork — and most people deal with it by smearing it around with a cloth. The Kärcher WV 5 Plus takes a different approach entirely: it vacuums the moisture directly off the glass and into a 100ml reservoir, leaving the surface genuinely dry rather than just redistributed. The standout feature here is the edge guidance system, which lets the suction head clean flush to window frames without leaving a wet strip at the border — something cheaper window vacs consistently fail to do.

Who Is This For?

This is built for people in older or poorly ventilated homes where winter condensation is a daily reality, and for anyone who tiles, cleans shower screens, or tackles large glass surfaces regularly and finds squeegees too slow and towels too streaky. It's also genuinely useful after mopping hard floors — the vac lifts standing water rather than leaving it to evaporate. If you only deal with condensation once a week on one small window, a £12 squeegee will honestly do the job.

What Buyers Say

Owners of the WV 5 Plus consistently praise the battery life improvement over earlier Kärcher window vac models, with most reporting enough charge to cover an entire ground floor in one pass. The edge cleaning is frequently singled out as a genuine upgrade. The most common gripe is the small reservoir — 100ml fills quickly on larger windows, meaning you'll be emptying it several times per session on big glazing panels, which interrupts the rhythm considerably.

The Deal

At £59.99 against a listed was-price of £89.99, this looks like a 33% saving — but our price history across 274 data points shows the average selling price is £60.10, meaning this is essentially the standard going rate rather than a meaningful discount. It sits right at its lowest ever recorded price, so you're not paying over the odds. For more options in this category, see our best home cleaning deals. A fair price for a capable tool — just don't let the "was £89.99" label convince you you're getting a bargain that isn't really there.
