The best window vacuum cleaner 2021: banish smears and condensation

Get your windows and mirrors squeaky clean and streak-free with the best window vac

The best window vacuum cleaners

The best window vacuum cleaners are tailor-made to remove the fine dirt and dust from your window using any window cleaning spray, resulting in a streak-free finish. They're also great for removing condensation from windows.

So what do you need to look out for when you’re buying your window vacuum cleaner? First, the run time. While a window vacuum cleaner with an average 35 minute charge time may be perfectly fine for whipping your way around a bungalow in one go, or indeed cleaning your car windows, those with a three-storey townhouse will need to accept that multiple charges will be required. 

Second, you’ll need to consider the shape of the head – has it been optimised to get into the tightest grooves of the window frame or is an additional head required to get into these nooks and crannies? Finally, the price. Think about how often you’re going to use your window vacuum cleaner and whether it’s worth splashing the cash for one that won’t cop out on you halfway through a cleaning mission. 

We think the best window vac currently on the market is the Karcher WV5 Premium 2nd Generation. Read on for our full rundown.

Karcher promises a streak-free, drip-free finish when used with its own branded cleaning products, although reviewers say any window cleaner will do. 

In addition to the product itself, you get a spray bottle, a micro-fibre head to remove stubborn dirt and a 170mm suction nozzle for getting right into those edges. The only negative seems to be the heaviness of the unit, with some reviewers mentioning it makes their arm ache after long periods of use.

Working alongside a decent window cleaner, Leifheit says the gadget should provide a streak-free finish, although reviewers say the the hoover head that it comes with struggles to get right into the edges. 

While cheaper than the Karcher at the top of our list, the accessories for this window vacuum must be paid for as an extra. Accessories include Leifheit’s click-system telescopic handles, which are perfect for reaching conservatory roofs.

-Shorter run time than WV5 

While 10% shorter and lighter, the smaller sibling of the WV5 should still do a good job of doing what Karcher promises: a streak free finish. The best thing about this version is its ability to fit into places the the bigger one can’t – for example glass panels on doors or walls. 

sAlthough the running time is 10 minutes less than the WV5, the charging time is significantly less, which means you should be able to work your way around a multi-story building without too much fuss. The positive comments echo across both products, but to get the streak-free finish that Karcher promise, it seems like your technique has to be right.
