Make the Most of ISSA 2024: A Guide For Facilities Managers

If you're evaluating commercial drones for building cleaning, you're not shopping for a hobby quadcopter. You're making a capital equipment decision, one that affects your crew's safety, your job capacity, and how you bid work going forward.

This comparison covers the drones actually being used for commercial exterior cleaning today, what they cost, what they do well, and where they fall short. No filler, no speculation.

Quick Comparison

1. Lucid Bots Sherpa: Best for Commercial Facade and Window Cleaning

The Sherpa is the only purpose-built aerial pressure washing drone with commercial contractor-grade specs. It's designed for the same operators who currently budget scaffolding, swing stages, or rope access to clean mid-rise facades, curtain walls, and large commercial windows.

Key specs:

• Cleaning rate: 300+ sq ft per minute
• Pressure: 4,500 PSI
• Flight time: ~19 minutes per battery cycle
• Vertical reach: up to 150 ft
• Water supply: ground-based, fed through a lightweight hose

What it replaces: A scaffolding setup for a 10-story facade can run $15,000 to $40,000 in equipment rental and labor before a single gallon of water hits the building. The Sherpa lets a two-person crew do the same job from the ground: one operator flies the drone, one manages the ground rig. No swing stage permits. No OSHA fall protection coordination. No half-day setup.

ROI: Most operators recover the equipment cost within two jobs when they're replacing scaffolding or lift rentals. On a $2,950/month Lucid Refresh subscription, the monthly payment typically runs well under the cost of a single aerial lift rental, which means the subscription pays for itself before the month is out on an active schedule.

Best use cases:

• Mid-rise and high-rise facade washing
• Commercial window cleaning (exterior)
• Curtain wall and glass panel cleaning
• Concrete and brick pressure washing at height
• Solar panel cleaning on commercial arrays
• Coating and sealant application on tall structures

Pricing: The Sherpa is available outright at $45,750, or through the Lucid Refresh subscription at $2,950/month. The subscription includes maintenance, software updates, and technical support.

Honest limitations: The Sherpa runs on battery cycles, so large jobs require either multiple batteries or scheduled charging windows. It's not a continuous-operation system the way a tethered unit is. For very high-volume, all-day industrial coating work on massive structures, that cycle management is a real operational consideration.

2. Apellix W1: Best for Continuous Industrial Application

Apellix makes a tethered aerial system designed primarily for industrial painting and coating on large structures like oil tanks, marine vessels, and infrastructure assets. It's a different tool for a different buyer.

What makes it different: Because it's tethered, the Apellix W1 isn't limited by battery life. It can operate continuously as long as the ground power source runs. That's a meaningful advantage for all-day industrial coating projects where crew downtime between battery swaps would compound across a long job.

Where it fits: If your work is primarily large-scale industrial coating on refineries, port infrastructure, or storage tanks, Apellix is worth evaluating. It's built for that environment.

Where it doesn't fit: For commercial building cleaning, facade washing, or window cleaning, Apellix is not the right tool. The tethered design limits maneuverability around complex building geometry. It's also priced and configured for industrial buyers, not commercial cleaning contractors. The two systems serve different markets.

What to Know Before You Buy

A drone is only part of the system. Operators consistently flag three things that determine whether aerial cleaning actually works in their business:

1. Ground crew requirements. The Sherpa needs a two-person crew at minimum. One flies, one manages the water supply and ground equipment. If your current jobs already run two-person crews, this is a direct substitution. If you're trying to run solo, aerial cleaning adds a headcount requirement.

2. Water source logistics. The Sherpa pulls water from a ground-based supply. On most commercial jobs, that means a water tank truck or a building-side hookup. Contractors who already operate pressure washing trucks have the infrastructure.

3. FAA Part 107. Flying commercially requires a Part 107 Remote Pilot Certificate. It's a written exam, and most operators pass within a few weeks of study. Lucid Bots' onboarding process walks new customers through it.

The Case for Autonomous Ground Cleaning

Not every cleaning challenge is at height. For ground-level pressure washing on parking garages, warehouse floors, and large hardscape surfaces, the Lavo Bot is worth knowing about. It's an autonomous ground pressure washing unit that runs independently while your crew handles other tasks. Contractors who run both aerial and ground work are increasingly pairing the Sherpa and Lavo Bot to cover a full site without dedicating a human to every surface.

Frequently Asked Questions

How much does a commercial cleaning drone cost? The Lucid Bots Sherpa is priced at $45,750 purchased outright, or available through the Lucid Refresh subscription at $2,950 per month. The subscription includes maintenance and support. Apellix does not publish pricing publicly. Their systems are priced for industrial buyers rather than commercial cleaning contractors.

Do I need a license to fly a commercial cleaning drone? Yes. Any commercial drone operation in the U.S. requires a Part 107 Remote Pilot Certificate from the FAA. This is a written knowledge test. The process typically takes two to four weeks of preparation. It's a one-time certification, not a per-job permit.

Can a drone actually clean a building effectively? At 4,500 PSI and 300+ sq ft per minute, the Sherpa cleans at commercial pressure washing standards. The limiting factor is usually water supply logistics and job planning, not the drone's cleaning capacity.

How does drone cleaning compare to scaffolding or swing stage costs? Scaffolding and swing stage rentals for a 10-story building typically run $15,000 to $40,000 or more, depending on building complexity and duration. On jobs where the Sherpa replaces a lift rental, operators often recover the monthly subscription cost within a single project.

What buildings is the Sherpa suited for? The Sherpa's 150-foot vertical reach covers most mid-rise commercial buildings like office towers, hotels, mixed-use buildings, and institutional facilities in the four- to twelve-story range.

The Bottom Line

For commercial building cleaning in 2026, the Lucid Bots Sherpa is the only purpose-built aerial pressure washing system designed for the commercial contractor market. The specs are real, the pricing is transparent, and the use case is specific: it's for operators who are currently spending significant money on scaffolding, lifts, or rope access to get water to the side of a building.

Apellix fills a different niche in industrial coating on large infrastructure assets, and is worth knowing about if that's your work.

If your business runs facade washing, exterior window cleaning, or high-rise pressure washing, the Sherpa is the closest thing to a direct answer.

This is for drone cleaning operators new or prospective who are worried that their market might not have enough demand to support a real business. If you've been hesitating to commit to a territory because you're not sure the opportunity is there, this post reframes the question entirely. The demand already exists in every market with commercial buildings. Your job isn't to create it it's to prove you can capture it faster, safer, and with less disruption than what property managers are already paying for.

The biggest fear most new drone cleaning operators have is that they'll need to convince an entire market that their service is worth paying for. They won't. Exterior cleaning demand is built into the physical world around us. Buildings get dirty. Property managers budget for cleaning. Facilities teams need reliable maintenance partners. Drone cleaning isn't introducing a new need, it's delivering a better solution to one that already exists and is already being paid for. That shift in mindset changes everything about how you approach territory validation. You're not looking for customers who might want exterior cleaning. You're finding ones who already buy it.

You're Not Creating Demand You're Capturing It

"The best way to find out if you can trust somebody is to trust them." Ernest Hemingway

The biggest fear new operators bring into drone cleaning is the belief that they need to create a market from scratch. They don't. Exterior cleaning demand is already baked into the world around you. Buildings get dirty. Property managers budget for cleaning every year. Facilities teams need maintenance partners they can rely on. The demand exists in every city, in every territory, in every market with commercial real estate above three stories.

Drone cleaning isn't a new need. It's a better answer to an old one. And that distinction changes everything about how you validate your territory and win your first revenue.

The Mindset Shift That Changes Your Approach

When operators think they need to create demand, they spend their energy on education explaining what drone cleaning is, why it exists, and why someone should care. That's a slow, expensive path. When operators understand they're capturing existing demand, the conversation shifts entirely. You're not convincing anyone to buy something new. You're proving that you can solve a problem they already pay someone else to solve faster, safer, and with less disruption to their tenants, guests, and operations.

That shift turns territory validation into a visible exercise. You don't need a research report. You need to drive around and look at buildings.

Where the Real Market Is The Mid-Rise Opportunity

Most people picture drone cleaning and think of skyscrapers. That instinct leads operators toward the wrong targets. Over 99% of commercial buildings in the United States are below 10 stories and the sweet spot for drone cleaning profitability sits squarely in the 4 to 10 story mid-rise range.

Mid-rise buildings offer maximum efficiency advantages from drone technology. They show dramatic before-and-after contrast that is visible from the ground. They tend to have predictable maintenance budgets and recurring cleaning schedules. And they include the highest-volume commercial property categories: hotels and extended-stay properties, office parks and corporate campuses, hospitals and medical office buildings, and industrial and warehouse facilities.

If you spend your early territory validation energy chasing the tallest buildings in your market, you'll miss the real opportunity. The money is in the middle of the skyline, not the top of it.

A Simple Market Sizing Formula

You don't need a research firm or an industry database to estimate the size of your territory. Spend two to three hours driving your market and counting commercial buildings over four stories. Then run the math. Take the number of buildings in your radius, multiply by cleaning frequency most commercial exteriors are cleaned two times per year and multiply again by average job size, which typically falls between $5,000 and $15,000 depending on your market and property types. That calculation gives you a working estimate of your annual addressable market.

As a concrete example: 200 buildings cleaned twice a year at an average of $8,000 per job equals $3.2 million in annual market value in a single territory, before you've knocked on a single door. The market is visible. You just have to look for it.

The Highest-Value Property Categories

Not all commercial properties are equally attractive as drone cleaning targets. The categories that consistently produce the best combination of deal size, cleaning frequency, and decision-maker accessibility are hotels and hospitality properties, which have strong aesthetic incentives and visible exteriors that directly affect guest perception; medical facilities and hospitals, which have large exterior footprints, strict maintenance standards, and facility management teams with real cleaning budgets; office parks and corporate campuses, which often manage multiple buildings under a single property management relationship; and universities, which have large, high-visibility building inventories and facilities departments that plan maintenance on annual budget cycles.

Prioritize these categories in your early outreach and you'll spend your prospecting time where the conversion rates and job sizes are highest.

An Underrated Growth Channel: Interior Cleaning Companies

One of the most overlooked partnership opportunities in drone cleaning territory development is the large interior cleaning company. Commercial janitorial and facilities services firms often get asked by their existing clients to handle exterior work but most of them subcontract it out because of the complexity involved: lift rentals, workers' compensation risk for elevated work, specialized equipment, and operational overhead they're not built to manage.

Drone cleaning changes that equation for them. By partnering with a drone cleaning operator, an interior cleaning company can bring exterior services in-house, capture revenue they're currently passing to subcontractors, and offer a more complete maintenance package to the client relationships they've already built. For the drone operator, it's a warm introduction channel into accounts that have already said yes to regular commercial cleaning. In many markets, this partnership model can accelerate territory penetration faster than cold outreach alone.

The Big Takeaway

Your territory has demand. It has always had demand. Every commercial building that gets dirty and they all do represents a maintenance budget that someone is already spending. Your job as a drone cleaning operator is to prove, quickly and visibly, that you can solve the same problem with better outcomes.

Stop asking whether the demand is there. Start driving around and counting dirty buildings. Then go show what you can do.

This is for drone cleaning operators who want to make confident, professional method selections on every job — and for property managers and facility directors who want to understand why their cleaning vendor is recommending one approach over another. Method selection is one of the most important decisions in exterior cleaning. Using the wrong technique can damage surfaces, void warranties, and cost you client relationships. This post gives you a clear framework for getting it right every time.

One of the most common mistakes in exterior cleaning — drone or traditional — is using the wrong method for the surface in front of you. Drone cleaning changes how cleaning solutions are delivered, but it doesn't change the fundamental principles that determine what actually gets a building clean. Every exterior job falls into one of three categories: window cleaning, soft washing, or pressure washing. Each one has different chemistry, different pressure requirements, and a different set of surfaces it works on. Knowing the difference isn't just technical knowledge. It's what separates operators who build lasting client relationships from those who cause damage and lose accounts.

Drone cleaning changes how cleaning solutions reach a surface. It doesn't change what cleans the surface once they get there. The same three fundamental methods still apply to every exterior cleaning job — and using the wrong one is one of the most expensive mistakes an operator can make.

Here's what each method does, how it works, and when to use it.

Window Cleaning

Window cleaning is designed for glass and glazed surfaces where streak-free results are non-negotiable. The process applies a specialized cleaning solution that breaks down contamination, then rinses with DI-filtered water to prevent spotting. The critical variable isn't pressure — its water purity. Water that isn't filtered to near-zero parts per million will leave mineral deposits on glass regardless of how well the chemical step works. Pressure for window cleaning typically runs between 800 and 1,200 PSI — enough to rinse effectively without risking seal damage or glass stress. The short version: streak-free glass comes from chemistry and water quality, not force.

Soft Washing

Soft washing is the method of choice for mold, mildew, algae, and organic growth on surfaces that can't handle high pressure — stucco, EIFS, painted wood, certain brick types, and many roofing materials. The process applies a chemical solution, typically sodium hypochlorite combined with a surfactant, at low pressure and allows it to dwell on the surface for 10 to 15 minutes. During that dwell time, the chemistry kills growth at the root level rather than just removing it from the surface. A light rinse then removes the dead material. Because soft washing addresses the source of the contamination rather than just the visible symptoms, surfaces stay cleaner longer after a soft wash than after a pressure wash. Operating pressure stays under 300 PSI, with flow rates around 10 to 12 GPM. The risk of surface damage at those parameters is minimal when dilution is correct.

Pressure Washing

Pressure washing uses mechanical force — high-pressure water — to remove surface contamination from hard, durable materials. It produces immediate visual results and works well on concrete, pavers, and certain metal surfaces where the structure can tolerate the force involved. Operating pressure can reach up to 4,400 PSI with flow rates under 8 GPM. The limitation of pressure washing is that it works at the surface level only. It removes what's visible without addressing the underlying biology, which means regrowth happens faster than it would after a soft wash treatment. Pressure washing is the right tool in the right context — it's not the right tool for every surface, and applying it incorrectly causes real damage.

Matching the Method to the Surface

Glass calls for window cleaning — filtered water, chemistry, and moderate pressure in the 800 to 1,200 PSI range. The only thing that matters more than pressure on glass is water purity. Stucco and EIFS are among the most damage-prone surfaces in commercial exterior cleaning. They require soft washing at under 200 PSI — high pressure on these materials strips finish coats, forces water behind cladding, and voids manufacturer warranties. Brick sits in the middle. It can often tolerate soft washing or light pressure in the 200 to 800 PSI range, but it always deserves a test patch first since older mortar can be fragile. Metal panels are variable depending on finish and coating — low to moderate pressure generally applies, and reactive chemicals should be avoided entirely. Concrete is the most forgiving surface in exterior cleaning and can handle pressure washing up to around 3,000 PSI, with soft washing as an effective option when organic growth is the primary issue. Always check for sealer compatibility before applying chemistry to concrete.

Why Method Selection Is a Professional Differentiator

Property managers who have had a building damaged by the wrong cleaning method don't forget it. High pressure on stucco strips finishes. Incorrect chemistry on metal panels causes oxidation. Pressure washing on roofing materials forces water under shingles. Each of these mistakes is preventable with basic method knowledge — and each one costs an operator a client relationship that could have been worth years of recurring revenue.

Professional cleaning is about method selection, not brute force. Drone cleaning doesn't replace that judgment. It rewards it — because operators who combine the access advantage of drone technology with the right method knowledge can take on jobs that traditional competitors can't safely execute.

The Big Takeaway

Knowing which method to use, and why, is what separates professionals from operators who cause damage and lose accounts. Soft washing, pressure washing, and window cleaning each have a purpose. Learn them well, apply them correctly, and your clients will notice the difference — and keep calling you back.
