Who is this for?

Holiday-let turnaround cleaners

If you clean several large glazed doors and other smooth surfaces between bookings, consider the full cleaning round when comparing runtime, head width and tank capacity.

Hosts with awkward balcony glazing

If doors have divided panes, low edges or hard-to-reach glass, check narrow-head options and whether every pane can be cleaned from a safe position.

Small-property or occasional-use hosts

For a modest number of panels, compact handling and storage may matter more to you than the longest stated runtime.

What matters when choosing?

Establish a safe working position for every pane before comparing head sizes and runtime. Then match the head to the door layout and the battery to the entire cleaning round.

Concern What to check Who this matters to
Safe access Check whether each pane can be cleaned from inside or another safe working position. For cleaning work at height, the Health and Safety Executive advises avoiding it where reasonably practicable. If reaching the outer glass would mean leaning over a railing, I need a safe way to do the job before considering cleaning speed. Around 42% of consumers put safe access first.
Turnaround capacity Compare stated runtime, head width and dirty-water tank capacity against all the surfaces in the cleaning round. Kärcher lists a 280 mm head, 150 ml tank and 100-minute runtime for the WV 6 Plus. When several broad panels need cleaning between stays, I want to know whether one charge will cover the planned round. Completing large glass areas is the primary concern for around 33% of consumers.
Narrow panes and edges Confirm the exact kit’s head sizes and whether a narrow nozzle is included or sold separately. If the doors have sidelights, divided panes or awkward edges, I need a head that fits those sections as well as the main panel. Around 25% of consumers prioritise this detailed access.

Buying pitfalls

  • Choosing by runtime alone

    A long stated runtime does not tell you whether the head fits narrow sidelights or framed sections. Kärcher lists one 280 mm suction head for the WV 6 Plus, while its WV 5 Plus has interchangeable 170 mm and 280 mm heads.

    Count the broad panels and narrower sections, then check the head sizes included with the exact kit.

  • Treating an extension handle as a safety solution

    Extra reach can still leave someone leaning or working from an unsafe position. The Health and Safety Executive advises avoiding work at height where reasonably practicable.

    Plan to clean from inside or another safe working position where possible. Do not lean over a balcony railing to reach the glass.

  • Assuming every kit includes the same accessories

    Head sizes and bundled accessories differ by model and set. Leifheit lists a narrow nozzle separately for the base Dry&Clean, but includes one with its All-n-one set; Bosch GlassVAC kits also vary.

    Check the exact model and supplied accessories before ordering, including the availability of any replacement blades or cloths you expect to use.

Relevant brands to consider

Kärcher

The WV 5 Plus and WV 6 Plus present different choices between interchangeable heads and longer stated runtime.

  • Kärcher UK lists 170 mm and 280 mm interchangeable heads, a removable battery and 35-minute runtime for the WV 5 Plus.
  • Kärcher lists a 280 mm head, 150 ml tank and 100-minute runtime for the WV 6 Plus.
  • These are manufacturer specifications. Check head fit against narrow sections rather than using stated runtime alone to choose.

Bosch

Bosch describes GlassVAC as a compact option for confined spaces and offers different accessory sets.

  • Bosch DIY UK lists 280 mm and 140 mm heads and a 120 ml tank for the GlassVAC Full Set.
  • Bosch DIY UK lists replacement GlassVAC blades and cloths.
  • Confirm the precise GlassVAC kit: included heads and stated performance differ by version.

Leifheit

The Dry&Clean range offers a compatible reach system and a narrow-nozzle option for awkward glazing.

  • Leifheit lists a 28 cm suction width, 38-minute battery life and Click System handle compatibility for Dry&Clean.
  • Its All-n-one set includes a 43 cm handle and 28 cm and 17 cm nozzles.
  • A reach handle is useful only where the cleaner can remain in a safe working position; check which accessories the chosen set includes.

Frequently asked questions

How much runtime should a window vacuum have for balcony doors?

Choose stated runtime against the whole cleaning round, including any other glass you plan to clean, rather than one door. Kärcher lists 100 minutes for the WV 6 Plus and 35 minutes for the WV 5 Plus; allow room for interruptions rather than treating manufacturer figures as a promise for your property.

Do I need both a wide and a narrow suction head?

Both are worth considering when broad door panels sit beside narrow or divided glazing. Kärcher lists 170 mm and 280 mm heads for the WV 5 Plus, while Bosch DIY UK lists 140 mm and 280 mm heads for the GlassVAC Full Set; check the contents of the kit you intend to buy.

Does an extension handle make exterior balcony glass safe to clean?

No: a handle extends reach but does not make an unsafe working position safe. For cleaning work at height, the Health and Safety Executive advises avoiding it where reasonably practicable; assess whether the glass can be cleaned from inside or another safe position before choosing a reach accessory.

Which accessories should I check before ordering?

Check the exact kit for the head sizes, charger and cleaning accessories you need, then consider how you will obtain replacement blades or cloths. Bosch DIY UK lists replacement GlassVAC blades and cloths, while Leifheit’s Dry&Clean narrow nozzle is included in the All-n-one set rather than the base vacuum.
