Commercial window cleaning requires far more than basic tools and ladders. Modern buildings feature complex façades, high level glazing and sensitive internal environments that demand specialist equipment, trained operatives and detailed planning.
From high rise offices to retail frontages and heritage buildings, professional window cleaning relies on a range of access systems and technologies designed to deliver safe, consistent and high quality results.
This article explores the key equipment used in commercial window cleaning and explains how different methods are selected to suit each environment.
Why professional equipment matters in commercial window cleaning
Commercial buildings present varied challenges. Height, access restrictions, footfall and architectural features all influence how windows should be cleaned.
Using the wrong equipment can lead to inconsistent results, safety risks or disruption to occupants. Professional window cleaning equipment allows trained teams to clean efficiently while protecting people, property and the building fabric.
According to the Health and Safety Executive, work at height must be planned and carried out using suitable equipment and competent staff. This is why reputable providers invest heavily in specialist tools and training.
Equipment used for high level window cleaning
High level window cleaning covers work carried out above ground level where specialist access systems are required. These environments demand advanced equipment, detailed risk assessment and highly trained operatives.
Building maintenance units
A building maintenance unit, often referred to as a BMU, is a permanent access system installed on many commercial towers. BMUs allow cleaners to reach high façades safely using suspended cradles or platforms.
BMU cleaning requires WAH specialists who understand the building’s design, load limits and movement patterns. At DOC Cleaning this work is delivered in house by teams trained to the highest level, supported by detailed planning and digital proof of delivery.
Rope access systems
Rope access is used where BMUs or platforms cannot reach. It is particularly effective on complex façades, curved glazing or recessed areas.
According to IRATA International, rope access provides a safe and efficient method when carried out by trained technicians following strict procedures. Rope access cleaning requires specialist skillsets, anchor inspections and continuous supervision.#
Mobile elevating work platforms
MEWPs are commonly used where temporary access is required or where façades are set back from the building line. They allow controlled access for high level window cleaning while maintaining visibility and safety.
MEWP operations require certified operators and clear exclusion zones to protect building users. This method is often used for targeted cleaning or planned maintenance cycles.
Water fed pole systems
Water fed pole systems use purified water delivered through telescopic poles to clean windows from ground level. This method is effective for high level glazing up to several storeys and is widely used on commercial façades.
Water fed pole cleaning reduces the need for access equipment while still delivering streak free results. It is particularly useful on buildings with open perimeters or landscaped surroundings.
Low level and internal window cleaning equipment
Not all commercial window cleaning takes place at height. Low level and internal glazing still require careful equipment selection, especially in occupied spaces.
Low level window cleaning often takes place in corporate offices, tenant occupied areas and front of house spaces. In these environments discretion, safety and cleanliness are essential.
Teams use professional squeegees, microfibre systems and specialist solutions designed for internal use. Equipment is selected to minimise noise, avoid overspray and protect furnishings.
Traditional window cleaning methods still play a role in certain settings, particularly on heritage properties or smaller façades where modern systems are not appropriate.
Understanding client needs is critical. Cleaning schedules, team size and access times are all planned to suit each location and minimise disruption.
Specialist cleaning equipment used alongside window cleaning
Commercial window cleaning often forms part of a wider specialist cleaning programme. Façades, entrances and external surfaces all influence how clean a building appears.
Façade cleaning and pressure washing
Façade cleaning equipment includes low pressure washing systems, soft wash technology and controlled pressure washers. These tools remove built up dirt, pollution and organic growth without damaging surfaces.
Pressure washing is used carefully and only where suitable, supported by trained operatives and surface assessments.
Graffiti removal systems
Graffiti removal requires specialist products and equipment to lift paint without harming the underlying surface. Steam based systems, low pressure washers and chemical free solutions are often used on sensitive façades.
These services support building presentation and asset protection, particularly in high visibility urban locations.
High end retail window and façade cleaning equipment
Retail environments demand exceptional presentation. High end retail cleaning relies on precise equipment, proof of delivery and teams trained to work around customers and premium displays.
Independent boutiques and department stores require careful handling of glazing, signage and shopfronts. Cleaning equipment is selected to deliver flawless results while protecting finishes.
Electric vehicles are often used to support sustainability goals and reduce disruption in city centres. Digital reporting tools provide proof of delivery and visibility for facilities teams.
Common equipment and where it is used
The table below outlines key equipment types and their typical applications in commercial window cleaning:
| Equipment type | Typical use | Key benefit |
|---|---|---|
| BMU systems | High rise façades | Safe access for complex elevations |
| Rope access | Irregular or recessed glazing | Precision cleaning in hard to reach areas |
| MEWPs | Targeted high level work | Flexible access with clear control |
| Water fed poles | Multi storey exteriors | Efficient cleaning from ground level |
| Internal glazing tools | Offices and retail | Discreet cleaning in occupied spaces |
This variety allows cleaning providers to tailor their approach to each building.
Training and planning behind the equipment
Equipment alone does not deliver quality. Professional window cleaning depends on training, planning and operational control.
WAH specialists must understand access systems, weather conditions and emergency procedures. Detailed risk assessments and method statements support every clean.
At DOC Cleaning all high level window cleaning is delivered by in house teams trained to the highest standard. We use 3D mapping and site specific planning to understand building geometry and access routes before work begins.
Why equipment choice supports ESG goals
Modern commercial window cleaning also supports sustainability objectives. Electric vehicles reduce emissions. Water fed pole systems minimise chemical use. Planned access reduces repeat visits and energy consumption.
Digital reporting improves accountability and reduces waste. According to the Institute of Workplace and Facilities Management, sustainable building services depend on efficient systems and accurate data.
