Which window vacuum suits your flat, your windows and your budget.
Our recommendation among window vacuums: streak-free, and as the Premium version with both the wide AND the narrow nozzle in the set, so also suitable for glazing-bar windows. Around 35 minutes of battery is enough for a typical flat. It works equally well on mirrors, tiles and in the shower. The right choice for most households.
The top model for many and large windows: 100 minutes of battery runtime, three times as long as the WV 2, for around 100 windows per charge. Larger 150 ml tank, precise multi-stage LED indicator. Only the wide nozzle is in the set, and a narrow one can be bought separately. For the whole house or large glass areas without recharging in between.
The brand alternative from Bosch: particularly compact (16 cm), with a wide and a narrow nozzle in the set. The special feature: Bosch explicitly promotes it for car windows too, an all-rounder for flat and vehicle. Around 30 minutes of runtime, spray bottle and microfibre attachment included.
The well-thought-out all-round set from the German brand Leifheit: the only one in the comparison with a telescopic pole, so you can reach tall windows, roof windows and conservatories without a ladder. Plus window washer, spray bottle and two nozzles. Up to 38 minutes of battery. For anyone who wants not just the vacuum but the complete cleaning set.
The cheap Kärcher entry: the same streak-free technology as the bigger models, but the lightest appliance in the comparison (0.5 kg) at the lowest Kärcher price. 20 minutes of battery (≈ 55 m²) is enough for a small flat with few windows. Only the wide nozzle is in the set, and if you want more, the WV 2 costs only a little extra.
Streak-free windows at the lowest price: often around €29 and still with spray bottle, microfibre attachment and a large 150 ml tank. Around 30 minutes of battery. No branded build quality, no narrow nozzle and no pole, but for beginners, occasional cleaners or as a cheap second appliance, the honest budget pick.
You spray the pane, wipe it with the microfibre cover and then pull the vacuum down from top to bottom. The appliance sucks the dirty water into the tank instead of leaving streaks or drops. Used correctly, the result is streak-free, with no need to polish afterwards. Important: empty the tank in good time and work in even strokes.
For most people, the Kärcher WV 2 Premium with wide and narrow nozzle. Many or large windows: WV 6 Plus (100 min). Tall windows: Leifheit with pole. Also for the car: Bosch GlassVAC. Tight budget: Sichler under €30.
The models differ mainly in battery runtime and accessories: the WV 1 Plus (20 min, wide nozzle only) is the cheap entry for small flats, the WV 2 Premium (35 min, wide + narrow) the choice for most, the WV 6 Plus (100 min, large tank) for many and large windows. The basic streak-free technology is identical in all of them.
For glazing-bar windows you need a narrow nozzle, which the WV 2 Premium, Bosch GlassVAC and Leifheit include in the set (the WV 6 and WV 1 only the wide one). For tall windows, roof windows or conservatories, the Leifheit Dry & Clean is the choice: it is the only one with a telescopic pole, so you do not have to climb a ladder.
Yes: window vacuums work on all smooth surfaces: mirrors, bathroom tiles, shower walls and glass tables. Pulling the water off glass and tiles after showering helps prevent limescale and mould. The Bosch GlassVAC is explicitly designed for the car; with the narrow nozzle it also reaches narrow side windows.
