Sparkleclean,
I do appreciate you taking time to take & post the 2 pics. A video showing how the booms avoid each other would have been better but ... hey .... the pics do help some. Just like I suspected ... your climate & most others' is mild enough so you can get by without overhead
doors on both ends of each inside bay.
One thing about going over innovations etc with others on this forum ... is that many really don't have a good enough sense of what it is like to run a car wash where the winter time temperatures average as low as we have here in North Dakota. Not to mention the frequent winds that go along with the cold weather. I think Swampdonkey, some in Canada, & a few others can relate but they tend to be the exception.
We stored some perfectly good & even brand new nevery used 360° booms that hopefully we will find time to mount .... but not in the center of the bay but still not too close to the wall .... on the
coin box side. There is no law that says that a ceiling mount 360° boom can't be used on a side wall several feet from that specific wall with a strong enough wall bracket creating the flat mounting surface to add to greater ease of use. We are pretty sure we can make it work ... maybe even without having the selection on the
coin box. That would save a ton of money if we can avoid the
coin box & Hydrospray's automatic 3 way valve. It might be wishful thinking but I am thinking that we will get enough regular customers (with word of mouth) to just use a manual valve right next to the
coin box. The trick might be to have clear ALERT blinking leds with "plain as day signage" if the valve was ever in the position of even partially routing the high pressure into the undercarriage wand. The undercarriage wand gun must be able to release water ... weep etc ... blow out etc ... & in our case we (& I believe our customers) prefer the variable pressure releasing ... on non trigger pull dump guns (albeit more expensive to buy initially).
Our stored booms look very similar to your center mount boom ... more straight than the Z booms ... the straightness we think will work in the customers' favor. Time will tell ... we will have to hold off somewhat until we get further along on our major laundromat 32 washing machine renovation. Ideally, we would be able to take advantage of some late winter & early spring usage. Some of our self service competition seems to have gone all in on fragrance - upholstery .... tri foam dis & dat ... so hopefully myself & my 2 or three employees will have a unique & a bit of a humble niche in other ways.
Sparkleclean .... have you found any significant usage of the undercarriage wand-rollers during the late spring, summer, & early fall??? Is it pretty much just a wintertime thing???
