Who is this for?

Mirror-edge cleaners

Framed, narrow or divided wardrobe mirrors put head width at the centre of the choice. Kärcher UK lists a 170 mm nozzle in the WV 2 Plus N kit, while Bosch DIY UK lists a 140 mm head in the GlassVAC Full Set.

Post-move whole-home cleaners

If mirrors are one stop in a clean that also includes windows, tiles or shower screens, compare stated runtime and dirty-water capacity alongside the heads supplied.

Small-space occasional users

If the appliance will spend most of its time in a cupboard, check its body dimensions and the space needed for its accessories. Bosch DIY UK describes the standard GlassVAC as compact for confined spaces.

What matters when choosing?

Start with the shape of the wardrobe mirrors and the surfaces you intend to clean in one session. Head access, working time, storage and the preparation tools supplied then become easier to weigh against one another.

Concern What to check Who this matters to
Mirror edges Check the nozzles in the exact kit: Kärcher UK lists 170 mm and 280 mm heads for WV 2 Plus N; Bosch DIY UK lists 140 mm and 280 mm heads for GlassVAC Full Set. With frames, narrow panels or handles beside the glass, I need a head I can place close to the edges. Around 38% of consumers would put edge access first.
Longer sessions Compare stated runtime and tank capacity for the exact model. Kärcher UK specifies 100 minutes and 150 ml for WV 6 Plus, against 35 minutes and 100 ml for WV 2 Plus N. When the move-in clean extends beyond mirrors, I want to limit charging and tank-emptying breaks. Longer-session capacity would be the main concern for around 31% of consumers.
Handling and storage Check body dimensions and where the appliance and its accessories will fit. Bosch DIY UK describes the standard GlassVAC as compact for confined spaces. Working beside furniture and putting the tool away afterwards matter more to me than covering a large area at once. Around 24% of consumers would prioritise handling and storage.
Occasional use Check that the instructions permit mirror use and whether the kit supplies the cloth and spray applicator needed before vacuuming. For occasional mirror touch-ups, I would rather have the preparation tools I need than capacity for a whole-home clean. Simplicity would come first for around 7% of consumers.

What should you avoid overlooking?

  • Assuming every kit has a narrow head

    A product-family name does not establish which heads are in the box. A wide head may be awkward to position on divided mirrors or close to wardrobe fittings.

    Check the exact model, order number and package contents. Kärcher UK lists two widths for WV 2 Plus N, and Bosch DIY UK lists two for GlassVAC Full Set; do not assume other bundles contain the same heads.

  • Choosing by runtime alone

    Longer stated battery life does not tell you how a head will fit beside a mirror frame. Extra working time is most relevant when you plan to clean several surfaces in the same session.

    Decide how much glass you will clean at once, then check head widths, body dimensions, runtime and tank capacity together.

  • Starting on dusty glass and frames

    Loose dirt around a wardrobe frame can be drawn back onto glass as you clean. A window vacuum collects liquid after the surface has been cleaned; it does not replace that preparation.

    Remove loose dust from the frame and nearby surfaces first. Bosch DIY UK advises applying cleaning fluid with a spray bottle and microfibre cloth before using the window vacuum.

  • Putting the appliance in household rubbish

    A rechargeable window vacuum also needs an end-of-life disposal plan. GOV.UK advises taking electrical products and batteries to an appropriate recycling collection point rather than putting them in household rubbish.

    Check the electrical-waste collection options available to you when the appliance reaches the end of its useful life.

Relevant brands to consider

Compare named models and bundles rather than assuming that every window vacuum from a brand has the same heads, runtime or accessories.

Kärcher

The WV 2 Plus N kit is relevant to tight mirror edges; the WV 6 Plus offers a longer stated runtime for a broader cleaning session.

  • Kärcher UK specifies 170 mm and 280 mm nozzles for WV 2 Plus N, with a 35-minute runtime and 100 ml dirty-water tank.
  • Kärcher UK specifies 100 minutes and a 150 ml tank for WV 6 Plus. These manufacturer figures do not establish how either model will perform on a specialist-coated or damaged mirror; follow the mirror maker's care guidance.

Bosch

The GlassVAC range is worth comparing where manoeuvring beside furniture matters, but head options depend on the bundle.

  • Bosch DIY UK describes the standard GlassVAC as compact for confined spaces and lists 140 mm and 280 mm exchangeable heads for the GlassVAC Full Set.
  • Bosch states a 30-minute runtime for the standard GlassVAC and 35 minutes for the Full Set. Check the exact order number before relying on a particular head or accessory.

Tower

Good Housekeeping Institute included a Tower Cordless Window Vacuum in its August 2026 UK window-vacuum roundup.

  • Its inclusion makes the named Tower model another window-vacuum option to investigate for the move-in clean.
  • Check the exact model's head widths, runtime, included accessories and suitability for your mirrors before comparing it with the named Kärcher or Bosch kits.

Common questions

Can I use a window vacuum on wardrobe mirrors?

Yes, if the product instructions permit mirror use and the mirror is a suitable smooth, waterproof surface. Kärcher UK and Bosch DIY UK describe mirror use for their window vacuums; for specialist coatings, damaged edges or particular care requirements, follow the mirror maker's instructions first.

Do I need a narrow suction head?

A narrow head is most useful when panels are divided or fittings leave little room beside the glass; a wider head may be practical on one uninterrupted mirror. Check the exact bundle: Kärcher UK lists a 170 mm nozzle for WV 2 Plus N, while Bosch DIY UK lists a 140 mm head for GlassVAC Full Set.

How should I clean mirrors that are dusty after a move?

Remove loose dust from the frame and surrounding area before cleaning the glass. Bosch DIY UK advises using a spray bottle and microfibre cloth to apply cleaning fluid, then collecting the liquid with the window vacuum. Check the mirror maker's care instructions before applying any fluid.

What should I check for ongoing use?

Check the exact kit's supplied cloth, spray applicator and cleaning fluid, as contents vary by model. Empty the dirty-water tank after use, and check how to obtain compatible cloths or replacement blades for the model you choose.

Can a rechargeable window vacuum go in household rubbish?

No. GOV.UK advises that electrical products and batteries should be taken to an appropriate recycling collection point rather than put in household rubbish. Check your available electrical-waste collection route when the appliance reaches the end of its useful life.
