THE FLIGHT LOG

Four Colorado buildings, as we flew them.

Three finished, one in progress. Every number here is one we published ourselves: the height we flew, the years of buildup we took off, the days it took.

The stadium had not had a detailed exterior cleaning in more than a decade. Exhaust soot sat on glass curtain walls and angled metal facades that rise over 90 feet.

We cleaned the sooted metal sills and the glass in the same passes, reclaimed the dirty runoff to Denver's city requirements, and finished two days ahead of schedule.

The complex sits under a skylight beside busy roads, so decades of exhaust soot had settled on the glass and the white decorative beams, and the birds had added their share.

The ground was the real problem: delicate stone walkways with a snow-melt system just beneath the surface. A boom lift or a crane could crush the heating elements and crack the stone, so heavy machinery had to stay off the walkways.

Key sections of the exterior had gone more than five years without a cleaning. Those sections had no roof anchors, so rope drops were impossible there, and a safety net about eight feet around the roofline kept any crew away from the edge. The most demanding glass sat directly beneath the LifeLine helicopter team's active helipad.

We kept constant radio contact with the LifeLine team, monitored live air traffic through the whole operation, and worked to a formal safety plan for any inbound helicopter.

Case study in progress

The old airport tower at Stapleton, now FlyteCo Tower, was our job in March 2024, and the one the press came out to watch. Denverite watched the aircraft work at 164 feet. Our own case study is still in progress.

BusinessDen, Denverite, DroneXL, FOX31 Denver and DroneLife reported on this job in 2024.

WHAT WE CLEAN

What we clean, and how.

The METHOD line under each service is how we do it: water, heat, pressure and, where the stain calls for it, FoamStream.

Seen from inside through tall white-framed windows, a drone outside sprays the glass against a blue sky.

THE PRE-FLIGHT

Planned like a mission.

Every site gets its own plan.

How a mission runs

  1. PRE-FLIGHT

    Assess the site

    Before the first flight we assess the site, set a safety perimeter and stage the water filtration.

  2. LIFT-OFF

    Water from the ground

    A tethered hose carries water and cleaning solution from our rig on the ground up to the drone, which sprays the glass from about ten feet away.

  3. THE RINSE

    Work the glass

    The aircraft works the glass in precise patterns and finishes with a rinse of purified water that dries spot-free.

Where a lift cannot go

The stone walkways

At the arts complex, delicate stone walkways hide a snow-melt system just beneath the surface. A boom lift or a crane risked crushing the heating elements and cracking the stone, so we worked from the air and kept heavy machinery off the walkways.

Denver Performing Arts Complex

No roof anchors, a helipad above

At the hospital, key sections had no roof anchors, so rope drops were impossible there, and a safety net about eight feet around the roofline kept any crew away from the edge. The hardest glass sat beneath an active medevac helipad.

The pilot

The FAA certificates the remote pilot, not the company, and we treat that certificate as the floor, not the ceiling.

The FAA Part 107 certificate is the bare minimum to fly a drone. It's like saying someone has a driver's license and assuming they can operate a semi-truck.

Jay Hanna, Co-Founder and CEO

No drone-specific OSHA standard, yet

OSHA has not written a standard specific to drone cleaning yet. Its General Duty Clause still binds us: a place of employment free from recognized hazards. OSHA covers the ground; the FAA covers the air.

THE RIG

Heated water, purified water, and FoamStream.

Our tools are water pressure, chemistry, filtration and heat, and the technique that puts them together. Here is what is in the tank and what comes out of the nozzle.

A yellow cleaning drone sprays a concrete pier beside windows reflecting mountains, with wet streaks across the facade.
Washing in progress: a jet on the concrete beside the glass.

FoamStream™

Clings longer.Cleans deeper.Rinses spotless.

FoamStream™ is our own cleaning system, "a fully engineered application system, inspired by industrial automatic car wash technology." Like a car wash it works on chemistry, dwell time, pressure and rinse: the foam sprays beneath the surface contamination and clings while it works, so the rinse carries the grime off.

A yellow drone sprays a broad sheet of white foam down a vertical band of exterior windows.

Heated water, 100°F to 220°F

Our industrial heaters deliver water between 100°F and 220°F, with steam-assisted applications for large and complex structures. On the hottest settings you can see the steam.

Purified water

We rinse with ultra-purified RO/DI water, deionized or reverse-osmosis, so nothing is left on the glass to dry into spots or mineral buildup.

Pressure, in our figures

900-1500 PSI

Window systems run around 900-1500 PSI at the nozzle, sprayed from approximately ten feet away; the pressure that reaches the glass is significantly lower, comparable to an automatic car wash.

4,000 psi

High-pressure washing, up to 4,000 psi, for masonry, concrete and industrial surfaces.

We choose the aircraft for the building, the height and the site conditions.

QUESTIONS

Straight answers, before you call.

How does drone window cleaning work?

A tethered hose carries water and cleaning solution from our rig on the ground up to the drone, which sprays the glass from about ten feet away. Before the first flight we assess the site, set a safety perimeter and stage the water filtration; then the aircraft lifts off, works the glass in precise patterns and finishes with a rinse of purified water that dries spot-free.

How high can you clean?

We like to stay below 150 feet. Over 150 feet, wind shear and stability at altitude call for additional planning, and the hose setup limits how high a drone can clean efficiently. The highest job we have published is 90 feet. A taller building is a conversation with a project manager.

Is drone window cleaning safe for the glass and for the people below?

Our window systems run around 900 to 1,500 PSI at the nozzle, sprayed from approximately ten feet away; the pressure that actually reaches the glass is significantly lower and comparable to an automatic car wash. Below the aircraft we mark a safety zone perimeter with caution tape, cones and barricades, put MUTCD standard signage on any sidewalk or street we work near, and station visual observers with the pilot.

Do you need roof access, and will you disrupt my tenants?

In most cases roof access is not required. We fly from the ground, which keeps disruption to tenants and building operations to a minimum, and we review the site in advance to settle staging and access.

What happens in wind, cold or sun?

Wind decides the day. Sustained wind of 0 to 10 mph is ideal; 10 to 15 mph is case by case with a limited scope; 15 mph or more, or gusty, is a no-fly, and we build at least one buffer day into the schedule. We never work in direct sunlight, because chemistry drying on glass must be avoided. In winter we work above about 42 degrees Fahrenheit with heated purified water, and we postpone when freezing makes cleaning unsafe or ineffective.

Do you use chemicals, and where does the runoff go?

When a surface needs it, yes: surface-appropriate chemistry with purified water, chosen for the dirt, the material and the conditions. Whenever possible we clean with purified water only, which is how we keep the environmental impact down. On tough stains our FoamStream system clings longer and rinses spotless. Where city or state rules require it, we reclaim and dispose of the wastewater.

What if the windows have not been cleaned in years?

Heavy mineral staining or long-term neglect is beyond a maintenance wash: drone cleaning alone will not fully restore that glass. We recommend restoration first, by rope access or traditional methods, and once the glass is restored the drone comes back to keep it clean. At the hospital in Colorado Springs, five years of sun-baked scale took a slower restoration clean with hot water and more pressure, and the glass came out spotless.
