Kärcher - Window Vac WV 2 Plus N

The WV 2 Plus N runs for up to 35 minutes on a single charge via its integrated battery, which is sufficient for cleaning multiple windows in a typical home before needing to be plugged back in. Its dirty water tank holds 100ml, meaning you'll need to empty it periodically during larger jobs such as cleaning patio doors or conservatory panels. It comes with two squeegee attachments — a 280mm and a 170mm — making it adaptable for both large panes and narrow frames.

This model is well suited to homeowners who regularly clean interior windows, shower screens, and mirrors, as it removes streaks efficiently without leaving residue behind. However, it is not designed for outdoor use in wet weather and the 100ml tank fills up faster than expected on large glazed surfaces like conservatories, so you may find yourself emptying it several times mid-task. Users expecting to clean an entire conservatory roof in one go may find the battery life and tank size limiting compared to the higher-spec WV 6 models.

This product has only recently been tracked, so there is no historical price data available to confirm whether £64.99 represents the lowest it has been sold for. The listed RRP is £79.99, making the current discount 19%, which is a reasonable saving on paper — but without prior price history it is not possible to verify whether this discount has been offered before or whether a lower price has previously appeared at retail. Treat the saving as plausible but unconfirmed until more price history is established.

The Vileda Windomatic is the WV 2 Plus N's most direct competitor and is frequently available at a similar or slightly lower price point, often between £35 and £55. The Kärcher edges ahead with its longer battery life, more robust build quality, and the inclusion of two squeegee widths in the box, whereas the Windomatic tends to have a larger tank but a less powerful suction motor. If you clean large surface areas frequently, the Kärcher is the stronger choice; if budget is the priority and your usage is light, the Windomatic remains a credible alternative.
