A sink where you can get money to wash properly. Switching from program to program takes a very long time, and it is much faster at other car washes. And the most annoying thing is when you have one ruble in your pocket and you just need to knock down the dust, and there was a client in front of you and his last program was with foam, then you will leave in foam.
There is no Foam or Active foam in the program selection menu at the post, only foam with water or heavy dirt with a brush (there is just active foam here, but the brush is heavy and the pleasure is money-consuming). I had to spend 20 rubles and use all possible options to be able to more or less launder. Another disadvantage is the top program or number 1, just which Foam with water is NOT EFFECTIVE!
