Earl,
When you say,"complicated" is is because they are electrical instead of hydraulic? Also, I have been looking a AVW and I like what I see. I am still doing my due diligence.
I had the previous incarnation. Worked great so long as you pay a lot of attention to them. The last set I saw at a show may or may not have been refined by now but they had air controls and adjustments, perhaps air over oil controls that governed retraction and extension. These required adjustments based on wear and temperature. Before I answered this I looked at the Belanger sight and video. See how the wraps bang into the end as they travel forward. Multiply that by a few hundred thousand. But they need to move fast to follow at speed. To lessen the impact and to get it to initially walk back quicker I used bungee cords. These took the shock as they reached max length before impact. They also helped the initial retraction. I had since at other locations gone to AVW and Sonny's and had at that location installed a second Set of AVWs. I now have replaced the belanger's with AVWs. IMO the pendulum style are just so much simpler. I do not have retracts so there are no air controls or cylinders. Just shocks and the angle / weight of the unit make it follow.
I sooke with AVW and the sales guy said that if I get the free standing wraparounds then I should also include an air cylinder and stabilizer kit too.
Why?
I have two sets of quick fires in two different locations for about 5 years now. There is nothing that cleans the fronts, sides and backs of the cars better in my opinion. That being said they do require a lot of attention. I would not say that they are complicated, there are a few key adjustments that have to be monitored regularly. If your not the hands on type or are looking for a set it and forget it type of machine than these definitaley are not for you. But then again I don't know of any wrap that is like that and cleans well. Comparativaly I've had the Belanger Gyro wraps in two other locations years ago and these are basically just glorified van high side washers. Maybe at a very slow chain speed in a small tunnel they would suffice but not if you are doing any kind of volume. The quick fires will follow the backs of the cars for about 8-10 feet as cleaning the back of the car over and over until the brush reaches the end of the boom. As you speed the chain up you turn the air pressure up slightly on the main cylinder so it keeps up with the car. They do break some rear wipers from time to time on certain cars like Ford Explorers but as long as you are using enough soap to lubricate the foam this really shouldn't happen.
Thank you for your valuable feedback. I have decided to get the quickfires.
Out of curiousity, do they help eliminate the prepping front grill as well as backs for your wash?
These will be in addtional to my current wraparounds. They leave a skunk stripe and the grills are always dirty. I'm Trying to eliminate prepping.
