Alternatives to ladders for cleaning atrium windows
Atria, double-height lobbies, and high-glass spaces are the exact use case where indoor mast lifts replaced cherry pickers and scaffolding for routine window and ceiling cleaning. Here is the equipment that works.
Why atria are a special case
Atrium cleaning combines three problems that defeat most equipment: working heights of 5 to 8 metres (above stepladder, sometimes above standard mast lift), polished or stone floors that punish heavy units (cherry pickers and scissor lifts leave marks or score the surface), and limited access to bring equipment in (standard 800 mm doorways and goods elevators sized for 1.0 m payloads).
For working heights up to 6 metres, the right equipment is a 6 m indoor mast lift. Above that, the equipment options narrow significantly and most atrium cleaning is contracted out to specialised access-equipment teams.
Why ladders fail for atrium cleaning specifically
The standard atrium cleaning task is the glass on the inner face of a double-height lobby, which sits at 4 to 7 metres of working height. On a stepladder, the operator has one hand on the rail, one on the squeegee, no third hand for the bucket, no fourth hand for the cleaning solution. Every reposition requires climbing down, moving the ladder along the glass, climbing up. For a single 30-square-metre atrium glass facade, ladder-based cleaning is a 4 to 6 hour single-operator job. With a 5 m or 6 m mast lift, the same job is 60 to 90 minutes.
Equipment options ranked for atrium cleaning
| Equipment | Working height ceiling | Floor friendly? | Doorway / elevator? | Reposition speed |
|---|---|---|---|---|
| 5 m or 6 m indoor mast lift | Up to 8 m | Yes (rubber castors, 230-470 kg) | Fits 800 mm / 1.0 m | Fast |
| Small scissor lift | Up to 6 m | Variable (heavier, can mark soft floors) | Often does not fit standard doorways | Medium |
| Cherry picker / boom lift | Higher reach | No (tracked or wheeled, heavy) | Cannot enter most atria | N/A indoors |
| Erected scaffold | Any (multi-day) | Yes | Rented installation | N/A (static) |
| Rope access | Any | Yes | Trained team only | Slow setup |
For routine indoor atrium cleaning at 5 to 8 metres of working height, the indoor mast lift is the only equipment category that combines fast reposition, floor protection, and atrium access. For above-8-metre or non-recurring jobs, rope access or scaffold rental are competitive.
Floor protection and stability calculations
Atrium floors are usually stone, polished concrete, or hardwood. The mast lift's stability calculation under EN 280 covers a 230 to 470 kg unit weight with rubber castors and parking brake. On polished stone, the load distribution does not exceed standard atrium floor loadings. The unit does not leave marks on stone or sealed wood. On unsealed wood or marble, use floor protection mats during transit.
Cherry pickers and scissor lifts at 6-metre working height typically weigh 1,400 to 2,500 kg with smaller contact patches and can damage atrium flooring. This is one of the dominant reasons facility managers move away from cherry-pickers for routine atrium cleaning.
How to evaluate this for your specific atrium
Three measurements determine the answer:
- Working height: top of the glass facade above the floor. If under 8 m, indoor mast lift fits.
- Doorway access: clear width of the route from goods entrance to atrium. If over 800 mm, mast lift passes.
- Floor surface: stone or sealed wood? Mast lift fine. Marble or unsealed surface? Use protection mats.
Our dealer network runs a free site walk-through for atrium evaluations. We send a technician with the right working-height tier, your team uses it for the routine cleaning round, the time difference makes the case.
Frequently asked questions
How do you clean a 6 metre atrium window without scaffolding?
An EN 280 Type 1 / Group A mast lift in the 6 metre working-height class. The unit fits standard 800 mm doorways, weighs 230 to 470 kg with rubber castors that protect stone and wood floors, and the operator stands on a level platform with both hands free for squeegee and cleaning solution. Routine 30-square-metre facade cleaning takes 60 to 90 minutes per round.
Will a mast lift damage the atrium floor?
Mast lifts in the 5 to 6 metre working-height class weigh 230 to 470 kg with rubber castors. Load distribution does not exceed standard atrium floor loadings on stone, sealed wood, or polished concrete. On unsealed marble or wood, use floor protection mats during transit. Cherry pickers and scissor lifts at the same working-height class weigh 1,400 to 2,500 kg and routinely damage atrium floors.
Can the equipment access the atrium through standard doorways?
Mast lifts at 5 and 6 metre working heights have stowed footprints around 0.53 m by 1.4 m, fitting 800 mm rough-opening doorways with 740 mm clear width after door hardware. Most atria designed for hospitality or retail have wider goods entrances, so access is generally not a constraint.
What about above 8 metres?
Above 8 metres of working height, the indoor mast-lift category does not fit. Options are: rope access (preferred for non-recurring jobs), erected scaffold (preferred for multi-day jobs), or specialist contracted services with truck-mounted boom equipment if outdoor access permits. Most large atria above 8 metres are cleaned by contracted access teams.
