Bosch GlassVAC: The compact window vac, for the car too

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

By Seydhan Cakmak · Editor-in-chief · Updated: · AI-translated from the German original

The brand alternative to Kärcher comes from Bosch: at 16 × 10 × 22 cm the GlassVAC is especially compact and, thanks to its ergonomic shape, sits well in the hand. As with the WV 2 Premium, two cleaning heads are included: a wide one (266 mm) for large panes and a narrow one (133 mm) for tight windows. One feature sets it apart from pure window cleaners: Bosch explicitly advertises it for car windows too, which makes it a practical all-rounder for flat and vehicle. With around 30 minutes of run time (about 35 windows), a spray bottle and a microfibre attachment in the set, it is the solid choice.

Bosch GlassVAC: what works and what doesn't?

What works well

  • Also for car windows: Bosch explicitly advertises it for the car, an all-rounder for flat & vehicle
  • Wide AND narrow nozzle: Large panes and tight windows without buying extras

Points of criticism

  • Small tank, fiddly to empty: 100 ml, emptied via a small plug
  • Not always 100% streak-free: Occasional residue at the edge, wipe over briefly

Build quality & everyday use

What carries the Bosch GlassVAC in everyday use: Also for car windows (Bosch explicitly advertises it for the car, an all-rounder for flat & vehicle) and Wide AND narrow nozzle (large panes and tight windows without buying extras). You have to be honest about the weaknesses: small tank, fiddly to empty. 100 ml, emptied via a small plug.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“Bosch GlassVAC Cordless Window Vac: also for car windows and a wide AND narrow nozzle, with a small, fiddly tank as the trade-off. At 8.3/10 a fair deal from €61.”

Frequently asked questions about the Bosch GlassVAC

Can you clean car windows with a window vac?
With the Bosch GlassVAC, explicitly yes: Bosch names car windows as an area of use. The narrow nozzle suits side windows well, and the vac pulls steamed-up or washed panes streak-free. That makes it an all-rounder that keeps not just flat windows but also the car clean.
Bosch GlassVAC or Kärcher WV 2: which is better?
The two are very similar (compact, both nozzles in the set, about 30 to 35 min, streak-free). The Kärcher WV 2 is often cheaper; the Bosch is explicitly designed for the car too and a little more compact. Brand preference and car use decide.
How long does the battery of the Bosch GlassVAC last?
Around 30 minutes per charge, which is enough for about 35 windows or 105 m² of glass, enough for most flats in one go. The built-in battery recharges fully in about 130 minutes.
Is the Bosch GlassVAC streak-free?
Normally yes: properly wetted and pulled from top to bottom, it leaves clean panes. As with all window vacs, occasional residue can remain at the very edge, which you wipe off briefly with the microfibre cloth.
