There is often an opinion that cheap robotic car washes are not much different from expensive ones. Is it true? If you are a handy man and have repaired everything at home, everything in the garage - feel free to buy a cheap robotic car wash, you will have something to do. And now let's move on from jokes to a comparison of popular models of Chinese robotic car washes and Russian-made car washes. I will tell you what is worth overpaying for and what is their fundamental difference. Electromagnetic valves On the Russian-made Epi Carwash robot, the valves are installed horizontally so that they work for a long time and do not leak liquids. In the Chinese robot, they are installed vertically, which means that when the car is waxed, an emulsion gets into it, which leaves a white coating after drying. And the owner of the Chinese robot does not understand why these stains are and blames the suppliers of chemicals or water purification. The most unpleasant thing is that during the loss of quality, you lose customers! Chemical mixing station and electrical box In the Russian robot, it is located at the top and moisture ingress is excluded. In the Chinese, it is located at the bottom, where there is a risk of water and chemicals ingress. Pump power and what does it have to do with rotary couplings? Opinions on the market differ: which pump to install? 15 kW, 18 kW or 22 kW for better soap. What's the catch? Pay attention to the video between the Chinese and Russian rotary coupling. The Russian coupling has an input diameter equal to the output diameter, while the Chinese pump has a thin sleeve with small holes installed inside and no matter how powerful the pump is, you will not be able to achieve the required water pressure at the output. In fact, 30 or 40 bar reaches the nozzle in the Chinese robot. The Russian robot has a different device: whatever diameter came out of the pump, it reached the nozzle without narrowing, which means the power and quality of washing is higher. High-pressure electromagnetic valves They are installed on the shuttle, are responsible for distributing high pressure either to the horizontal arm or to the vertical one. The Chinese have valves with a capacity of 50 bar installed there. The Russian robot has a capacity of up to 90 bar. Chemical supply system The Russian robot uses high-quality fittings and valves in the chemical supply system, and the warranty on the chemical supply system is much higher - 5 years.
