Ecovacs, the leader of the home robot working group of the National Household Appliance Standardization Technical Committee, has been focusing on the R&D and manufacturing of home service robots for many years, and now has the world's only and most complete product line of home service robots. In 2011, Ecovacs was the first to develop window cleaning robot products, which is a well-deserved leader in the field of window cleaning robots. Ecovacs has strong strength, and in the field of household cleaning robots, 2 out of every 3 cleaning robots sold come from Ecovacs. In 2011, Ecovacs announced the birth of the world's first window cleaning robot. In 2013, Window Pwatch W730 won the "Science and Technology Innovation Award" of China Home Appliance Epplan, in 2015, Window Pwatch 9 series won the world's highest award for process design in Germany "Red Dot Award", and the following year W950 won the German iF Design Award and Red Dot Award, which can be described as a frequent winner in the field of window cleaning robots.
 
Ecovacs has a wide variety of products, including 7 series, 8 series and 9 series. Window treasure 8 series W830 is the highest selling window cleaning robot of Ecovacs, with rave reviews on the whole network, and the official website price is 1999 yuan. So far, more than 18,000 families have chosen this product. Different from other vacuum suction cup adsorption, W830 adopts the adsorption method of supersonic centrifugal fan, so that the high-speed rotating vacuum centrifugal fan is firmly attached to the glass, and it can produce a pressure of 2.5kpa by relying on this adsorption mode, which is equivalent to the power of ordinary people lifting 25 kg of heavy objects. If you hang a heavy object under the window treasure, it can bear a maximum weight of 9 catties, although the suction power is not as good as similar products of HOBOT, but it is enough. It has two built-in cleaning paths, "N" and "Z", which can measure, plan, and clean in one step, and can remove various stains such as powder dust, rain stains, and watercolor pen prints.
 
The W830 is also equipped with a control striker induction wheel, which can accurately calculate the area of the window by calculating the number of rolling revolutions, ensuring that no area is missed. At the same time, the window treasure remembers the position you placed on the window when it starts, and automatically returns to the starting position when it is cleaned, so that you can easily remove the machine from the window. The W830 is equipped with anti-drop sensors in all four corners, and when any corner moves to the edge, the sensor senses that there is no obstacle below and automatically adjusts the walking route, so that the fan will not fall over the glass surface, and can be used with confidence on frameless glass. In addition, Ecovacs Window Treasure is also equipped with two auxiliary tools, safety buckle, safety rope and spare lithium battery to avoid accidents, in the event of a sudden power failure, its own lithium-ion battery can last for 15 minutes, during which an alarm will be issued to facilitate users to deal with it in time.
 
The price of 2599 yuan of the window treasure W850 is a new upgrade of W830 products, from the original brush motor to upgrade to brushless motor, so that the internal structure of the main air duct is optimized, the service life is extended, not only that, its suction power is increased by 300pa compared with 830, and the adsorption is more stable. At the same time, W850 upgrades the rag to a floating rag that can be automatically lifted, even if the working interface is not a smooth medium, the rag can be tightly adhered to, compared with the previous W830, its rag area has been expanded by 1.3 times, more than 330 square centimeters. Cover a larger area and be more efficient in the same amount of time. In addition, the air outlet of the W850 has also been upgraded to a "U" shaped air outlet, which will produce less noise during operation.
 
  The biggest difference between the 9 series and the 8 series is that the 9 series adopts Ecovacs' patented smartdrive split drive system, which operates independently and cooperates with each other, simply put, the outer disc (square part) and the inner disc (round part) can rotate in any direction of 360°, so that the machine has four different forward directions in the process of traveling, reducing the number of times the machine adjusts the direction, thereby improving the efficiency of window cleaning. Its square cleaning unit is equipped with a dense fiber rag that can clean up the dead corners to the greatest extent,9 series can also be used for grid planning for the shape and size of the window,Use"Bow"Shaped cleaning path,The official claim is that its cleaning coverage rate is as high as 99.3%,If it is accidentally interrupted in the process of window cleaning,After starting again, it will continue to clean up the remaining area according to the original plan,Very intelligent,Such an excellent window treasure9 series,The price is naturally higher,W950The official price is 3399 yuan,And W930There is no sale for the time being。
