Hello Sooner. First let me say that I sell the Istobal line, so I am biased towards them. I do however work on most of the other machines out there so am familiar with them. Liked Ireland's answers, but again, I'm biased because I like their whisky. A lot. Anyway:
1. Ireland's answer is good. Just to clarify on the overlapping part. If it a 5 brush machine like the Rykos they really don't overlap, just come in together. On an Istobal the two side brushes come together, and then go side to side as a pair, on both the front and back. This totally eliminates the classic skunk stripe.
2. Nice feature to have if you have a lot of them in your market. They will though be the vehicles that cause the most trouble.
3. I've stopped selling them with machines. We just epoxy blue reflectors to the floor. Istobal makes a small yellow guide rail, and it's a joke. Because the eyes that detect the wheels are so close to the floor, a regular 4" pipe will mess them up. With the smaller rails you can't feel when the tire hits it. And I have switched from tire brushes that extend from the gantry to fixed
nozzle assembly that rotates and is recessed inside the gantry. The brushes will clean better but they are an easy target and require more maintenance, and if you use a kick butt tire chemical, it will do a decent job.
4. Again, I like most of what Ireland says. Let me give you a quick sales pitch on the Istobal foam material. They are the only company to my knowledge that makes their own foam material. And they don't sell it to anyone else. To give you an idea of its quality, do a search of Istobal and Lamborghini, and you will see the Istobal friction cleaning brand new $500,000 cars coming off the assembly line. Ferrari tested the material for three years to insure it would not scratch or dull the finish, and they have a machine also, but won't allow pictures. This material is also great to buff in a carnauba wax. We do a double wash pass, and then a double buff and shine with the carnauba. Finish with a quality wax and RO and the car will look hand buffed.
5. This is always an interesting area of auto washing. We can do a great job of washing a car and using an off board dryer, do it in around 3-1/2 minutes. However that is not always what the customer wants. Think of getting a haircut. No one likes to wait very long. BUT, when it's your turn in the chair, it's like take your time, do that talc powder afterwards. Really make me feel like I'm getting the best one ever.Yes it will take more time to do a car with a lot of features. You can however double your throughput very easily. Buy two machines.
6. Most all of the manufacturers can dress up a machine. You however can usually do it yourself cheaper by getting the frame wrapped. Istobal offers a choice of 14 colors to choose from for the brushes. And you can get them as one color, two, of alternate them. No extra charge for that.
7. I agree with most of Ireland's points. The only difference, and he wouldn't know this, if that the Istobal machine sold in the states is an Americanized version. They had some pretty good teething issues when the first machines were sold in the US. So the US guys in Bristol decided to do something about it. The machines today are simply a different animal than the older or foreign ones are. Different enough that they put a two year warranty on all parts. When any of our customers machines goes down (remember, Jesus did not build these machines, so they will go down) we know about it in 10 to 15 seconds, as it emails us and tells us what the issue is. If it's minor, we reset it from our phone and continue the wash. If any of you are down in FL on its west coast this winter, stop by and I'll give you a tour. And maybe even introduce you to that wonderful Irish whisky.
