Before the Washington Commanders raised their new inflatable practice dome in Ashburn, the fabric picked up dirt and grime that was only visible after the dome was inflated. A traditional cleaning crew could not touch it. Ladders lean against nothing and walking the surface risks a tear that costs six figures. The team called in a cleaning drone and the finished job went viral.

How Much Does Sports Dome Cleaning Cost, and How Often Is It Needed? Sports dome cleaning cost depends on square footage, membrane condition, and site access, and most facilities benefit from professional cleaning once or twice per year to control algae, mildew, and airborne pollutants.
Is Drone Cleaning Better Than Traditional Methods for Air Domes? Drone cleaning is faster, safer, and often 40 to 60 percent cheaper per square foot than traditional lift-based methods on structures above three stories, according to Lucid Bots' operational data.
How Do Drones Clean Sports Domes and Practice Bubbles?
Specialized cleaning drones safely soft-wash the delicate fabric of inflatable sports domes directly from the air.
An air-supported structure, as Wikipedia's technical overview explains, derives its structural integrity from internal pressurized air holding up a pliable fabric envelope. The fabric is usually a PVC- or Teflon-coated polyester or fiberglass, engineered to shed weather but not designed to support a boom lift bracing against it or a crew walking with pressure washers. The moment a lift makes contact, the membrane can dent, tear, or lose pressure. The moment a worker steps onto the surface, they risk a fall through the fabric or a puncture that requires a full deflation to repair.
Cleaning drones solve this by delivering the cleaning solution and rinse from above at a controlled standoff distance. The drone hovers off the surface, sprays a membrane-safe detergent, agitates dirt with either a low-pressure rinse or a brushing accessory, and rinses clean. No lift. No scaffolding. No foot traffic on the fabric. The result is a full exterior wash on a structure that most cleaning contractors cannot touch. VSI Aerial's drone cleaning services cover this application specifically, alongside window, facade, and solar panel washing.
Why the category is growing
Air-supported domes went from a niche solution to a mainstream way for schools, universities, and pro teams to add year-round practice space without building a permanent structure. As more of them go up, more of them need cleaning, and the industry is realizing that the cleaning problem needed a new tool.
How Do You Clean an Air-Supported Structure Without Damaging It?
To clean an air-supported structure safely, you must keep all personnel and heavy machinery off its delicate fabric. The thin, flexible membrane of a sports dome relies entirely on heat-sealed seams and internal air pressure to maintain its shape, meaning any puncture or tear can compromise the entire building. Traditional cleaning methods pose serious risks: foot traffic can rip seams, high-pressure washing can damage the protective PVC coating, and heavy lifts parked at the base can distort the dome's anchoring.
Drone soft-washing eliminates these risks entirely by avoiding physical contact with the structure. A certified operator flies the drone at a safe standoff distance, spraying a specialized detergent designed specifically for coated fabrics. Once the chemical solution lifts the dirt, the drone performs a gentle rinse, with the water naturally rolling off the dome's curved surface. For tougher grime like algae or mildew - which frequently grows on shaded, north-facing areas - the drone can simply apply a second pass. The entire cleaning process is completely touch-free.
Who Cleaned the Washington Commanders' Practice Bubble?
VSI Aerial cleaned the Washington Commanders' Ashburn practice bubble in spring 2026, operating a Sherpa cleaning drone manufactured by Lucid Bots. Coverage of the job has often blurred the distinction between the drone's manufacturer and the service provider who actually performed the cleaning, so the record is worth setting straight.
Local reporting from The Burn's original story accurately described the cleaning method: drones sprayed a gentle detergent on the dome, brushed and agitated the surface, then rinsed everything away, leaving the newly installed bubble looking new. What the coverage missed is that Lucid Bots builds the Sherpa drone. VSI Aerial is the FAA Part 107 certified commercial drone service that flew the mission on-site. The job required a licensed pilot, a ground crew, water and detergent supply, and airspace and safety planning around an active NFL practice facility. All of that came from VSI Aerial's team.
This distinction matters for facility managers evaluating whether to hire a drone cleaning service. Buying a Sherpa drone starts at $75,000, and operating one commercially requires a Part 107 pilot, insurance, and cleaning solution logistics. Most facility owners are not going to buy the hardware and stand up their own drone program. They are going to hire a service. That service, on the Commanders job and on other large-format cleaning work across the DC, Virginia, and Maryland region, is what VSI Aerial's drone cleaning services team provides.
How Much Does Sports Dome Cleaning Cost, and How Often Is It Needed?
Sports dome cleaning cost depends on the square footage of the membrane, its current condition, the site's accessibility, and how much algae or mildew has built up, but most large-format professional cleaning jobs land in a four- to five-figure range per visit. Cadence for most facilities is one to two full exterior cleanings per year, with spot cleaning for algae as needed.
Cost drivers on a sports dome are different from a typical commercial building wash. The total membrane surface area on a full-size practice bubble can exceed 100,000 square feet, so square-foot pricing scales fast. Site access matters too. A dome that sits behind fencing, next to active fields, or under airspace restrictions takes more planning. Detergent volume and rinse water logistics for a large dome are non-trivial. According to the Sports Venue Calculator's cost overview, general dome maintenance across all categories typically runs $3 to $6 per square foot per year, which includes blower power, HVAC, and membrane care combined.
On cadence, most dome operators can get away with an annual professional cleaning if the structure is in a low-pollution area and gets normal rainfall. Domes in humid climates, near heavy tree cover, or in industrial areas need more frequent attention because algae, mildew, and airborne particulates build up faster on shaded, north-facing sections of the curve. A twice-a-year cleaning schedule, timed around the start and end of the peak-use season, is a reasonable default for most commercial and athletic facilities.

Is Drone Cleaning Better Than Traditional Methods for Air Domes?
For sports domes and any air-supported structure above roughly three stories, drone cleaning is meaningfully better than traditional lift- or scaffolding-based methods on cost, safety, and speed. On short walls or fully rigid buildings a ground crew still competes, but on a curved pressurized membrane there is not really a contest.
The cost delta is documented. Lucid Bots' own operational comparison of drone versus traditional pressure washing puts drone cleaning at 40 to 60 percent lower cost per square foot for buildings above three stories, and 50 to 80 percent lower overall once equipment amortization is factored in. On a typical multi-story commercial wash, a four- to eight-person traditional crew takes three to five days for a job a single drone operator plus one ground crew member can finish in one to two days. The reason is the fixed overhead of scaffolding and lifts. Boom lifts alone run $500 to $2,000 per day. Full scaffolding setup can be $15,000 to $50,000. On a sports dome, those tools are not just expensive, they cannot be used safely against the membrane in the first place.
The safety math is even more one-sided. Traditional exterior cleaning on structures above three stories is responsible for a meaningful share of fall injuries and workers' compensation claims in the exterior services industry. A drone operator stays on the ground. Insurance premiums fall. The membrane risk goes to zero because nothing ever touches it. For the specific case of an air-supported dome, drone cleaning is not just the cheaper option, it is the only option that does not put the structure itself at risk. VSI Aerial's drone cleaning services team serves this application across the DC, Virginia, Maryland, and Mid-Atlantic region.
Frequently Asked Questions
Can you pressure wash a sports dome or practice bubble?
Standard high-pressure washing at close range can damage the PVC or Teflon coating on a sports dome membrane. Cleaning drones use a controlled, low-pressure soft wash with membrane-safe detergent applied from a standoff distance, which is why professional dome cleaning almost always uses the soft-wash method rather than traditional high-pressure equipment.
Do you have to deflate an air dome to clean it outside?
No. A properly executed drone cleaning is performed while the dome remains fully pressurized and in use. The whole point of drone soft washing is that nothing touches the membrane, so internal pressure, blower operation, and interior activities can continue during the exterior cleaning.
How long does it take to clean a full-size sports dome or practice bubble?
Most full-size dome cleanings can be completed in one to two working days by a two-person drone team, depending on the square footage of the membrane, weather conditions during the flight window, and how much algae or mildew treatment is required. A traditional multi-crew scaffold-based approach on the same structure would take significantly longer, if it were even possible on the fabric.
Are cleaning drones legal to operate on commercial properties?
Yes, commercial drone cleaning operations in the United States are legal when flown by an FAA Part 107 certified remote pilot in accordance with the applicable Part 107 rules for commercial small unmanned aircraft. VSI Aerial's team is Part 107 certified and carries appropriate commercial drone insurance for facility work.
What kinds of structures beyond sports domes can drone cleaning handle?
The same drone soft-washing method used on air-supported sports domes works on high-rise building facades, stadium canopies, solar arrays, warehouse roofs, industrial silos, and any exterior surface above three stories where lifts and scaffolding are expensive, slow, or dangerous. VSI Aerial's drone cleaning services cover all of these applications.
