I personally do not like the way the D&S 5000 travels over the vehicle.
I think the good ol inverted L sizes nicely, works nicely, has no spinners to foul up, cannot crush the cars by accident and makes the bay feel more open and inviting.
Let the criticism begin.
After 50,000+ washes, my D&S 5000 has never crushed a car. No damage of any kind, except for 1 drunk lady who got on the wrong side of the rails, and 2 who tried to drive duallys through.
As for the inverted L's, I'll jump in on that
Before I built my wash I had no
loyalty to my dist or D&S. At that point I had no idea how important it would be to use a strong local dist and to be loyal to one. So, my decision to go with a D&S 5000 was based 100% on my personal experience with them washing my own vehicles, and with other manufacturers. I was never impressed with any inverted L I used because they seemed to lack the punch/impingement that the D&S 5000 has. The D&S 5000 will rock your truck back and forth with its pressure, and while that may not mean much in terms of cleaning ability to us, in the customer's eyes, it means it's doing a good job.
I've been in roofing sales for 28 years, the car wash business for just 11 years. In those 17 years of knowing nothing about car washes, I would have never considered using a friction wash. My thinking was, hey, if a touchfree doesn't get my vehicle clean, at least I get another chance to get it right. But I only get 1 chance to not get scratches. I know I know, brush technology is better now, but until the industry makes that widely known to the customer, a high percentage of them will still not want a brush touching their car.
