Choosing between rope access and a cherry picker is not simply a question of how tall your building is. The best option depends on the façade, available roof and ground access, the size of the cleaning area and how the work can be carried out safely.
For block managers, facilities managers and building operators, the decision affects more than access. It can influence cost, scheduling, disruption to residents or visitors, and how reliably the work can be repeated.
We assess each building individually. Here’s how the two methods compare, and what we consider before recommending one.
What is the difference?
Rope access window cleaning uses technicians working from ropes secured at roof level or another suitable anchorage. Our rope access work is carried out by IRATA-certified technicians, with the access and safety arrangements planned for the specific building.
Cherry picker window cleaning uses a mobile elevating work platform, or MEWP. The machine lifts an operator in a work platform so they can reach the façade. Our powered access work is carried out by IPAF-licensed operators using equipment selected for the job.
Both methods can suit commercial and residential buildings. Neither is automatically the safer, faster or cheaper choice. The right method depends on the site.
When rope access is often the better fit
Rope access can be practical when a building’s layout makes it difficult to position a machine close to the façade. This may include tall or irregular elevations, recessed windows, awkward rooflines or areas where the ground below is restricted.
It can also be useful where the building has little space for a cherry picker, or where setting one up would interfere with entrances, parking, public routes or other site activity. Rope access has a smaller ground footprint than a MEWP, although a suitable work area and controls for people below are still needed.
Before recommending rope access, we consider whether the building has suitable roof access and anchorage arrangements, whether the façade can be reached as planned, and what rescue arrangements the job requires. A site-specific plan matters: not every roof or anchor point is suitable.
Rope access may suit your building if:
- The façade is complex, stepped or difficult to reach from the ground.
- There is limited space for a machine or its working area.
- A MEWP would need frequent repositioning to reach separate sections.
- Suitable roof access and anchorage can be established for the work.
For more detail on the method, see our guide to IRATA rope access cleaning.
When a cherry picker or MEWP can be the better fit
A MEWP can be efficient when the target windows are at a suitable height and the machine can be positioned close enough to the façade. It provides a stable platform for the operator and can work well when a large, repetitive area can be cleaned from one or a small number of positions.
Ground conditions are a key part of the decision. The machine needs a suitable place to stand and enough room to manoeuvre and operate. The site also needs to accommodate the machine’s reach, its setup and any barriers or exclusion zone required below.
A building’s surroundings can change what is practical. A machine may be limited by restricted access, parked vehicles, landscaping, overhead obstructions, uneven ground or the need to keep a route open. Where a cherry picker must be moved repeatedly, set-up and repositioning time can affect the programme.
A MEWP may suit your building if:
- The façade is reachable from an appropriate machine position.
- There is suitable ground and enough room to set up.
- Cleaning can be completed efficiently from a small number of positions.
- The working platform is useful for the specific task and façade.

How the methods compare
| Consideration | Rope access | Cherry picker or MEWP |
|---|---|---|
| Façade layout | Often suits complex, irregular or recessed elevations. | Often suits reachable elevations with a clear machine position. |
| Ground space | Usually needs less space at ground level, but still needs controls around the work area. | Needs space for access, setup and operation, including any required barriers. |
| Access requirements | Requires suitable roof access, anchorage and a planned rescue arrangement. | Requires a suitable route, machine position and equipment matched to the required reach. |
| Repeated access | Technicians can move along a façade using the planned rope system. | Can be productive when a platform can reach a large area without frequent moves. |
| Site disruption | May reduce the need for large machinery at ground level. | May affect parking, walkways or traffic, depending on the site. |
The HSE’s guidance on window cleaning explains why work at height must be planned and carried out by competent people using suitable methods and equipment. In practice, our recommendation also considers the building’s layout, surroundings and cleaning requirements.
Which method costs less?
There is no reliable rule that rope access or a cherry picker is always cheaper. The total cost depends on what the building requires, not just the name of the access method.
For a MEWP, cost considerations may include the machine needed to reach the façade, delivery and collection, the time it can remain in position, and any access or traffic arrangements. For rope access, the job depends on the specialist team, the rigging and safety arrangements, roof access and the number of working positions needed.
The amount of glass, its condition, the number of elevations and the planned cleaning frequency can also affect the price. A MEWP may be efficient where a large area is accessible from a suitable position. Rope access may make more sense where machinery cannot reach conveniently or would require extensive repositioning.
When comparing quotes, check that they cover the same elevations, cleaning scope, access method and site arrangements. Our guide to commercial window cleaning prices explains why access is an important part of a site-specific quote.
Can a building use both methods?
Yes. A mixed approach can be practical when different parts of a building have different access needs. For example, a MEWP might suit a reachable lower elevation, while rope access is more appropriate for a taller or recessed section.
We may also consider other methods where suitable. Some windows can be cleaned with water-fed poles from the ground, while buildings with installed access equipment may be suited to a building maintenance unit. The choice depends on whether the method can reach and clean the required areas safely and effectively.
How we recommend an access method
We start with a free site survey. We review the building height and layout, the windows to be cleaned, available roof and ground access, and any nearby pedestrian or vehicle activity.
From there, we prepare an access plan and quote based on the site. We agree the method and schedule with you before work begins, and we can discuss how to reduce disruption to residents, staff, customers or visitors.
After the clean, we complete a quality inspection and provide a written report. Our process is designed to make the scope, access method and next steps clear before the work starts.
Frequently asked questions
Is rope access safer than a cherry picker?
Neither method is automatically safer in every situation. The appropriate choice depends on the building, access conditions, task and planned controls. We assess the site and use trained, suitably qualified people with equipment and arrangements suited to the work.
Is a cherry picker suitable for high-rise window cleaning?
It can be, if the machine can reach the required windows and there is a suitable route and place to set it up. The building’s height is only one consideration; ground conditions, obstacles, available space and working reach also matter.
Is rope access window cleaning cheaper?
Not necessarily. Rope access may avoid some machine access and positioning requirements, while a MEWP may be efficient for a large area that is easy to reach. The overall cost depends on the building, work scope and site logistics. A survey is the best way to compare options fairly.
Can rope access clean a building with an irregular façade?
It can be suitable for some complex elevations, provided the façade can be accessed and the necessary roof, anchorage and safety arrangements are in place. We assess the building before confirming whether rope access is appropriate.
How do I choose between rope access and a cherry picker?
Share the building location, approximate height, which elevations need cleaning and any known access restrictions. We’ll survey the site, assess the available options and explain the recommended approach.
