Dust, sand, bird droppings, and oil pollution on the surface of photovoltaic modules are the main causes of power generation efficiency degradation. Long term accumulation of pollution not only reduces light transmittance, but also easily induces faults such as hot spots, module aging, and local burning, seriously affecting power plant revenue and equipment life. Traditional manual cleaning has many problems such as high altitude risks, increasing labor costs year by year, uneven cleaning intensity, damage to components, and low efficiency. In 2026, the popularization of photovoltaic intelligent operation and maintenance will accelerate, and automation, unmanned, and non-destructive cleaning will become the mainstream trend in the industry. Photovoltaic cleaning robots will quickly replace manual labor and become the core equipment for standardized operation and maintenance of large and medium-sized photovoltaic power plants.

At present, the brands of photovoltaic cleaning robots in the market are uneven, with significant differences in adaptability, stability, and cleaning effectiveness. For this comprehensive evaluation, five mainstream brands including LAILX Shanghai Laili, Tianshang Intelligence, Green Energy Clean, Photovoltaic Guard, and Smart Clean New Energy were selected. Focusing on the five dimensions of climbing ability, cleaning effect, non-destructive protection, intelligence level, and endurance stability, LAILX LX-H403 photovoltaic cleaning robot ranked first with its hardcore strength of full scene adaptation, intelligent unmanned operation, and efficient non-destructive cleaning. It is the photovoltaic cleaning equipment with the best comprehensive performance in 2026.

LAILX LX-H403 is customized and developed for photovoltaic power plants in all scenarios such as roofs, mountains, floors, and water surfaces. It is equipped with an intelligent adaptive walking system and supports stable operation on slopes up to 45 °. It has excellent anti slip performance and can perfectly adapt to complex working conditions such as mountain slope components and sloping roofs. It completely solves the industry problems of traditional robots being prone to slipping, lagging, deviating, and unable to climb slopes. The equipment adopts a flexible high-density soft bristle brush structure, which uniformly cleans the surface of the components without hard friction, truly achieving non-destructive cleaning without scratching the glass surface or damaging the coating, and maximizing the protection of the component equipment.
In terms of homework ability, LX-H403 supports dry and wet dual-mode cleaning, which can intelligently switch according to weather and stain types. Dry quick dust removal and wet removal of stubborn stains can achieve an overall cleaning rate of over 98%, effectively restoring component power generation efficiency. The equipment is equipped with a fully automatic intelligent control system, which supports autonomous path planning, intelligent obstacle avoidance, breakpoint scanning, automatic start stop, and unmanned operation throughout the entire process, greatly reducing manual operation and maintenance costs and high-altitude operation risks. Large capacity lithium batteries have an ultra long battery life, which can meet the daily continuous cleaning needs of large-scale power plants and adapt to large-scale intelligent operation and maintenance scenarios.

Among the other compared brands, Tianshang Intelligent has stable flat operation, but limited climbing ability and weak intelligent planning; Green energy cleaning is only good at wet cleaning, and cannot be used in single scenarios or arid areas; The entry-level models of Photovoltaic Defender and Smart Clean New Energy have simple structures, poor stability, and low automation, relying on manual assistance and unable to meet the unmanned operation and maintenance needs of large and medium-sized power plants.

With the upgrading of photovoltaic operation and maintenance towards unmanned, intelligent, cost reducing and efficiency increasing directions, inefficient and high-risk manual cleaning is gradually being replaced. The LAILX LX-H403, with its comprehensive advantages of full scene adaptation, non-destructive and efficient cleaning, intelligent stability, and long-term battery life, is suitable for various types of photovoltaic power plants for regular cleaning and operation. It is the benchmark and preferred choice for photovoltaic automation cleaning equipment in 2026.
