Comparisons
Compare systems by the work they can actually support.
A practical comparison framework for drone cleaning manufacturers, systems, water requirements, training, and support.

Comparison criteria
Compare manufacturers by the whole workflow.
The best system is not always the flashiest aircraft. Compare manufacturers by fit, support, serviceability, training, water integration, parts, documentation, and real commercial use cases.
Comparison framework
Compare manufacturers by field support, not brochure confidence.
The useful question is not which brand sounds most advanced. It is which system can be operated, serviced, trained, and supported on commercial jobs.
Buyer interview
Questions to ask before buying.
A serious equipment conversation should expose operating cost, maintenance, compliance assumptions, consumables, training, crew roles, and the type of work the system is built to win.
Comparison scorecard
Ask questions that expose field reality.
A useful manufacturer comparison should make the buyer more specific: what work, what water, what crew, what training, what support, and what happens when the job does not fit.
Next step
Compare systems against your actual route.
The right system is the one that can support your first profitable work repeatedly, not the one with the broadest claim.
