No drips, no streaks · review
Bosch quotes its runtime in windows rather than minutes — which is the number you actually wanted.
The bottom line A good machine with a genuinely useful runtime unit — check availability before ordering in the UK.
The Bosch GlassVAC states its battery life the way you would ask about it: up to 35 windows per charge.
Minutes are the industry’s habit and windows are what people plan by. Thirty-five is Bosch’s figure for ordinary panes, lightly soiled — a large glazed door counts as several, and heavy exterior grime needs a second pass. As a way to compare machines it is at least as honest as a minutes figure, and considerably easier to act on.
Shower screens, mirrors, tiles and splashbacks. Any smooth surface that holds water shows streaks when it is wiped, and none of them need a different technique: spray, wipe, then pull the water off with the blade so it ends up in the tank rather than on the sill.
They remove water; they do not remove limescale that has already etched into glass. A screen that is cloudy after years of hard water needs a descaling treatment first — after which a daily ten-second pass keeps it clear.
Verified on Germany, the United States, France, Italy and Spain. Verified absent from the UK store — readers there are sent to a local search rather than a dead page.

Both are estimates, and windows is the more useful one because it maps to your actual job. The caveat is the same in either unit: a large sliding door counts as several windows, and a filthy pane needs two passes. Use it to compare machines rather than to plan a morning.
Yes, and it is often better there than on glass. A bathroom mirror after a shower, a splashback, a tiled wall in a wet room — all are smooth, all hold water, and all show streaks when wiped with a cloth. The machine's job is removing water from a smooth surface, whatever that surface is.
