We customize body colors, carton printing and multi-language manuals to match the demands of different national markets. Equipped with full original standard accessories, two carton specifications suit full-container bulk shipments and small consolidated orders. Our stable production capacity supports orders from independent website merchants, offline supermarkets and property service contractors. The product holds complete international certifications including CE, FCC, RoHS and WEEE, and its wide-voltage design fits power grids all over the world for cleaning all kinds of indoor and outdoor smooth vertical surfaces. Throughout cooperation, full official test documents are provided for customs clearance. Custom delivery plans such as combo set packaging and batch split shipment are available to realize one-stop production and delivery for overseas orders.
This square Electric Window Cleaning Robot is integrally molded from engineering-grade ABS material, available in black and white. It features dual-side independent atomized water spray with two nozzles spraying 0.17ml water per minute, delivering even mist to cover around 120㎡ and dissolve tough stains effectively. Equipped with dual brushless drive fans running at 31,500 RPM without load, the machine maintains stable air pressure between 2400 and 2800Pa. Four high-sensitivity sensors (6-axis, photoelectric, water level and air pressure) detect window edges and water shortage with automatic audio-light alerts.
It stores 10 self-planned cleaning paths including vertical, horizontal, N-pattern and Z-pattern cross modes. The built-in UPS backup lithium battery keeps the robot working for 20-30 minutes after power cut, with a full charging time of 2 hours. Rated power is 72W under 24V voltage, compatible with global AC 100-240V power supply. A 5-meter safety rope with 135kg load capacity prevents falling risks. The service life reaches over 400 hours with low operating noise of 65dB, suitable for both residential and commercial scenarios.
Controlled by infrared remote controller with optional APP connection, it integrates anti-slip cleaning belt, automatic air flow adjustment, antifreeze algorithm and multi-language support. Certified with international safety and environmental standards, it comes with complete accessories including remote control and safety rope out of box. Full-range OEM customization on appearance, packaging and manuals is supported. Multiple carton sizes fit various container shipments for overseas retail stores, hotel buildings and stone curtain wall projects.

FAQ
Q1 Will the atomizing components inside the water tank of the Electric Window Cleaning Robot age and clog easily after long storage in high-temperature overseas warehouses?
The spray nozzles are made of high-temperature resistant ceramic and pass cyclic high-low temperature aging tests before delivery, resisting scale clogging during hot storage. Special dredging tools and maintenance guides are included in packages for distributors to provide after-sales guidance for end users.
Q2 Can we separately replace the plug types of power adapters matched with it for exports to different countries?
The voltage parameters of the main unit remain unchanged. Our factory can separately provide adapters with EU, US, UK and other standard plugs without modifying the machine structure, matching power socket standards worldwide.
Q3 Do you support customized extended safety ropes if we purchase it for large stone curtain wall projects?
Custom extended safety ropes are available on demand. All extended ropes pass the same load tensile tests, and their connectors are compatible with the main unit. We can work out separate packaging plans for bulk orders of extended accessories.
Q4 Can we pack the it as a gift set matched with our own cleaning detergent for sales?
Gift combo packaging customization is available. Our factory can adjust internal partitions of color boxes to reserve space for cleaning detergent, and customize the full printing design of packages to meet retail set sales demands directly.
Q5 Can you provide separate packing lists for each container if we place bulk orders of it for split container shipment?
Independent packing lists, weight details and corresponding certification documents will be issued for each split container shipment. The lists support multi-language printing to help overseas buyers store goods in separate warehouses and complete customs clearance in batches.
