What is the flight time under full load?

Under full load (60kg), the flight time is approximately 9 minutes. Without load, it can fly up to 35 minutes.

Does the drone support autonomous flight?

Yes. With the built-in dual-antenna RTK system and smart route planning, it can autonomously generate cleaning paths, including edge-sweeping routes to prevent missed spots.

AI-Powered supplier vetting

SummaryWuxi Wanlv Intelligent Technology Co., Ltd is identified as a China-based manufacturer/factory in Jiangsu, although another record describes the company nature as a trading company, creating an entity-classification inconsistency. The supplier offers solar panel cleaning brushes and robots, reports three production lines, 30,000 pieces of annual solar-panel-cleaning-machine productivity, 11–20 years of R&D engineer experience, and 6–10 quality-control staff. Its stated management certifications are OHSAS/OHSMS 18001 and ISO 9001. The company describes 24-hour after-sales assistance and flexible cleaning solutions. Evidence is insufficient to confirm financial credibility, customization or broader innovation services, and customer cases are not documented. Several operational, sustainability, OEM/ODM, overseas-service, and traceability attributes remain unknown.

CertificationsThe supplier reports OHSAS/OHSMS 18001 and ISO 9001 certification of its management systems. The provided slice does not include certificate scope, validity, or issuing details, but it explicitly records the certifications.

After-Sales capabilityThe company states that it provides an after-sales protection system and 24-hour after-sales assistance, intended to address customer concerns. This is explicit evidence of an after-sales service offering, although no service-level metrics or geographic coverage are provided.

R&D capabilityThe company states that it continuously optimizes its solar-module cleaning robot system and cleaning technology, and its R&D engineers have 11–20 years of total experience. ODM, SDK, private-mold, 3D-design, new-product, and last-year product-launch information is marked unknown, so broader innovation capability cannot be fully established.

Production capacityThe supplier reports three production lines, 6–10 quality-control staff, and annual productivity of 30,000 solar-panel-cleaning machines; export sales are reported at 51%–70%. These figures provide explicit evidence of production capacity, while order-fulfillment status is recorded only as “6” without a defined scale.

Product Q&A

Q:Can this drone be used at night or in low-light conditions?

Yes. It is equipped with FPV HD cameras and landing lights, allowing safe and efficient operation during night or low-visibility conditions.

Q:Is the drone suitable for cleaning rooftop solar panels?

Absolutely. The WLS-9YQ-LD1 is an ideal roof cleaning drone and building drone, designed to operate safely and efficiently on rooftop PV systems without the need for scaffolding or manual climbing.

Q:How does the drone avoid damaging the solar panels during cleaning?

It uses a non-contact, high-pressure spray system that cleans without physical abrasion. This prevents scratches and micro-cracks commonly caused by brushes or manual cleaning.

Q:What kind of cleaning liquid can be used with this drone?

The system is compatible with most common solar panel cleaning solutions or deionized water. We recommend using eco-friendly, non-abrasive liquids to ensure panel longevity.

Q:How is the drone different from a solar cleaning robot?

Unlike solar cleaning robots that require rails or flat surfaces, this drone is track-free and adaptable to complex terrains like roofs, hills, and deserts. It offers greater flexibility and zero installation cost.
