A good self-service car wash. The device accepts 100, 200, 500 AMD coins. There is water, foam, wax, vacuum cleaner. The employee makes sure that no one on duty is standing in the box and is in a bit of a hurry) On Sunday afternoon, the queue is quite small, one car in each box
One of the advantages is that the car wash worker helps with the promotion of the queue. There is water, foam, separately a large number of vacuum cleaners (6-8 like) boxes like 4-5. But the foam quality is very poor. She doesn't take dirt at all. If the car is clean, you only need to wash off the dust, then OK. But since the mud settles and eats into Yerevan after any rain, this foam will not cope with it.
A normal car wash, there was a free car wash on Saturday afternoon, there is a vacuum cleaner, a compressor. It took me 30 minutes and 900 drams to wash it. Of course, it is much more profitable than conventional sinks.
