“What are your ideas to improve in at automatic in this way?”
It depends on the circumstances – competition, market strength, owner personality, available resources, etc. In other words, it takes more than a pre-engineered, one-size fits all, “plug-and-play” equipment solution to achieve or exceed these results.
For example, “the issue of long wash times can be easily solved.”
Yes, it is relatively easy to increase hourly capacity through capital investment. However, it takes a bit more lifting to increase sales from $175K to $400K or so.
“Wash times are a subjective issue”
This holds true for self-serve and driveway washing. Otherwise, not true. For example, while total guest time on site may vary for various conveyor carwash formats, it generally takes 3 to 4 minutes to wash the exterior.
Once an in-bay is calibrated, for example, basic 4-minutes, good 5-minutes and best 6-minutes, the service times do not change. What can change is total volume which is dictated by what customers buy and how long they are willing to wait.
It also helps to know what you are doing.
For example, I recently got to observe conversion from self-serve to express format. Site went from wands plus two in-bays and
coin-op vacuums to wands plus one in-bay plus in-bay to conveyor conversion and
token-op vacuums, building extension, signage, etc.
First, the conversion took about three times longer than it should have and the wash was closed over the entire peak carwash season.
Second, this is a Grade B site at best due to characteristics like accessibility, ingress/egress, travel speed, visibility, signage, etc.
Third, so far, it mostly appears to be operated unmanned and no
marketing initiative (i.e. website, virtual
marketing,
loyalty program, etc.).
Again, it takes more than just equipment solution to get results.
