Kärcher WV 6 Plus vs Bosch GlassVAC
Which should you buy? Our verdict on both, pulled from our full The Best Window Vacuums: 4 Compared (and One to Skip) comparison.
The Kärcher WV 6 Plus is the most capable window vac here — longest runtime, a battery readout and a wide 280 mm blade and a narrow nozzle available for tight mirror corners. The Bosch GlassVAC is the smarter-value runner-up, bundling more in the box and shining on bathrooms, though its shorter runtime keeps it a step behind.
Kärcher WV 6 Plus
Buy itThe most complete window vac: long runtime, a digital charge display and an 11 inch (280 mm) wide nozzle.
- Around 100 minutes of runtime per charge — comfortably the longest here
- Wide 280 mm (11 inch) nozzle with an improved flexible blade for big panes and doors
- Digital display shows remaining battery, so you are not caught mid-window
- Weighs 1.7 lb (about 0.77 kg) per Kärcher
- Priciest of the four, especially once you add spare blades
- The US WV 6 Plus has no narrow nozzle in the box; Kärcher lists that with the WV 6 Premium and as a separate accessory
- It ships with a spray bottle, indoor cloth and cleaner concentrate you may already own
Bosch GlassVAC
Buy itA light, well-priced all-rounder that swaps between a large and small head and excels on mirrors and shower screens.
- Comes as a set with a spray bottle, microfibre wipe, both nozzles and a USB charger
- Two heads — a large squeegee for windows and a small one for mirrors, small panes and car glass
- Light and easy to steer one-handed on shower screens
- Micro USB charging means no proprietary brick to lose
- Runtime is short at roughly 30 minutes, so big cleaning days need a top-up
- No battery gauge — you clean until it fades
