Kärcher WV 6 Plus vs Bosch GlassVAC
Which should you buy? Here's the honest call, 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 two blade widths that handle both big glass and 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.
