A visibly dirty car park, warehouse floor, or hard-standing yard does not just create a poor impression. It creates slip hazards, accelerates surface deterioration, and in some environments raises compliance issues around dust control and contamination. KMG provides mechanical sweeping and scrubbing services for commercial and industrial sites across New Zealand, using purpose-built ride-on and walk-behind equipment to clean large hard-surface areas efficiently, thoroughly, and with minimal disruption to site operations.

Mechanical sweeping removes loose debris, dust, grit, and organic matter from hard surfaces using rotating brush systems and vacuum collection. Mechanical scrubbing goes a step further, applying water and cleaning solution to the surface under pressure from rotating scrub heads, then recovering the soiled water immediately. Together they address both the visible soiling and the ingrained grime that sweeping alone cannot lift.

Mechanical sweeping and scrubbing is one of the services that many exterior cleaning companies have to subcontract because they do not own the equipment. KMG has this capability in-house. We operate purpose-built ride-on sweepers and scrubbers suited to large commercial and industrial floor areas, as well as walk-behind equipment for tighter spaces, internal areas, and sites where a larger machine cannot manoeuvre. This means faster mobilisation, consistent equipment standards, and no third-party contractor arriving on your site under a different company's systems.

A single clean addresses the immediate problem. A scheduled maintenance programme prevents build-up, protects the surface over time, and removes the task entirely from the Facility Manager's to-do list. KMG works with clients to establish a sweeping and scrubbing cycle that fits the site's operational calendar and traffic levels, whether that is weekly, monthly, or on a seasonal basis.
Because our staff are directly employed, the same crews return to your site on each visit. They know the layout, the access points, the areas that accumulate soiling fastest, and any site-specific requirements your operations team has communicated. There is no re-briefing and no starting from scratch each time.

Mechanical cleaning on an operational site requires planning. KMG coordinates scheduling to minimise conflict with vehicle and pedestrian movement, manages water recovery carefully to avoid creating slip hazards during the clean, and ensures the site is left in a safe and accessible condition on completion. Our job management system handles scheduling, communication, and reporting so that coordinating the work places no additional burden on your team.
Multi-level and ground-level car parks accumulate tyre rubber, oil, grit, and organic debris that becomes a slip hazard when wet. Regular mechanical cleaning keeps surfaces safe, presentable, and protected from surface degradation.
Large-format concrete and sealed floors in warehouses, distribution centres, and manufacturing facilities require regular sweeping and periodic scrubbing to manage dust, contamination, and safety compliance requirements.
External hardstand areas, loading docks, service yards, and pedestrian plazas around retail and commercial buildings benefit from scheduled mechanical cleaning to maintain presentation standards and manage slip risk.
Unsealed and sealed yard surfaces at industrial and logistics sites accumulate heavy soiling that standard cleaning cannot address. KMG's equipment is suited to large-area, heavy-duty cleaning in these environments.
Schools, universities, and institutional campuses with large paved areas, covered walkways, and multi-level car parks require regular mechanical cleaning to maintain safe and presentable surfaces across the entire site.
Hospitals, medical centres, and rest homes need entranceways, walkways, and car parks kept clean and free of slip hazards for residents and visitors with limited mobility. We schedule around visiting hours and keep noise down in occupied areas.

Every KMG staff member who arrives at your building is directly employed by us, not sourced through a subcontractor or labour hire agency. We operate with 50+ staff nationwide, all trained to our internal standards and managed through our job management system. For Facility Managers, this means the same people return visit after visit, retaining your site knowledge and protocols without you having to re-brief anyone. Our compliance documentation, SWMS, toolbox meetings, and incident reporting are all managed in real time through our cloud-based HSE app, so you have full visibility whenever you need it.
KMG holds ISO 45001:2018 certification for occupational health and safety, a standard that many exterior cleaning companies in New Zealand cannot demonstrate. We are Site Wise Gold certified, the highest certification level available through Site Safe, and pre-qualified through both Impac Prequal and CM3. For Facility Managers who manage contractor approval processes, KMG arrives already vetted. No chasing documents. No compliance gaps.




"Auckland Museum is thrilled and said it was the best job in years. A big thanks to you and the team. It's awesome that we have such an amazing partnership with you, one of high standards and trust. You are very appreciated."
"It's been a few months since we kicked off the building cleans with KMG and I wanted to take a moment to acknowledge the outstanding work you've delivered. The results have been stellar."
"This round of window cleaning has yielded the most positive feedback from residents to date. The team gave great service, were super friendly and went the extra mile. Communication has been outstanding. Their work ethic is excellent and a thorough job is always done without exception."
Mechanical sweeping uses rotating brushes and vacuum collection to remove loose debris, dust, and grit from hard surfaces. Mechanical scrubbing applies water and cleaning solution under pressure from rotating scrub heads and immediately recovers the soiled liquid. Sweeping addresses surface debris while scrubbing lifts ingrained soiling and staining. Many sites benefit from a combination of both, depending on the surface condition and cleaning frequency required.
Most commercial car parks benefit from mechanical sweeping at least monthly, with a deeper scrub on a quarterly or bi-annual basis depending on traffic levels and surface condition. High-traffic car parks, particularly those in retail or hospitality settings, may require more frequent sweeping to manage safety and presentation standards. KMG can assess your site and recommend an appropriate schedule.
Yes. KMG schedules mechanical cleaning around your operational requirements and coordinates work to minimise conflict with vehicles and pedestrians. For sites that cannot tolerate any operational disruption, work can be scheduled outside business hours, overnight, or in staged sections across the site.
KMG's mechanical equipment is suited to concrete, sealed concrete, asphalt, paving, tiled surfaces, and industrial flooring. If you are unsure whether your surface is appropriate for mechanical cleaning, our team can advise during a site assessment.
KMG owns its mechanical sweeping and scrubbing equipment and operates it with directly employed staff. We do not subcontract this service. This means consistent equipment standards, faster mobilisation, and a single contractor responsible for the work and its outcomes.
Yes. Many Facility Managers combine mechanical sweeping and scrubbing with water blasting of surrounding surfaces and building washing into a single scheduled maintenance programme managed by KMG. Having one contractor handle the full scope reduces coordination, simplifies invoicing, and ensures all work is completed under a single compliance framework.
