Everything is fine, but it would be possible to clean up the dirt there because it is not only on the floor but also on the walls. And it's dark inside the sink, then you drive out the car and there you also wash it badly in some places because you can't see it.
The car wash is cool! The foam is thick and effectively cleans the car from dirt. The machine does not cheat. There is enough time to wash the car quite even twice as cheap
