Positive:
1 They can knock down dirt, which is not bad. True, not everywhere, but that's it. They probably know about the fenders. But they do not know that it has an arched shape. That is, it has a back and an upper part.
Minuses:
1. They have vague ideas about HOW cars are washed. Example. The body is doused with water from the AVD, then chemicals are applied, then, WITHOUT WASHING it OFF!!!!, they begin to rub along the body with dirt.
2 The fact that the body is dried with auto towels was not even suspected. I think it's unnecessary to talk about the fact that 1 car is 1 towel.
3. Purging of cavities with compressed air? ... Well, they can blow into locks and door handles. I don't even think they know about the niche of the fuel tank neck, mirrors, gaps between the headlights and the body, moldings, license plates, etc.
4. Rims and wheels. Just water from the AVD. They probably don't know that they need to be dried.
5. The chrome and glossy surface are wiped with a STIFF paper napkin. They are also trying to wipe the monitor of the head unit with it.
Conclusion: they can wash the car.
If you have a car, after washing it you will have to bring it to mind yourself because it will be all in divorces, and it's good if they don't scratch it. Do you need it? The choice is yours.
** for knocking down the dirt a la washed and vacuumed . As they say, without ...., but hardworking
