It will be few days more before it arrives. I got a 33,000 gallon ig plaster pool, that is sort of between the shape of somewhat widening rectangle, and a Lazy L with harldy any "L". Should be good test. I was using an old Aquabot Mark V, with a taped together power box. Sometimes, it did a quite decent job, just took forever and I was sick of using taped together item.
As said in prior posts, I had lost a new pool rover plus in Katrina, which had problems with prior oval pool of old destroyed house.
I was leaning at first to a bottom only type cleaner, that would work fast. However, no one had any reports on the Orion (and the problems with its manufacturer have been detailed here), and I couldn't trust whether a pool rover plus or aquajet might also have problems with shape of my new pool.
I wanted something with good coverage, clean fast and not cost arm and leg. I do believe that the less time the cleaners are in the water, the less opportunity to break. I looked at various refurbished models, but the price of brand new Blue Pearl was of interest. It was still 200$ less than refurbished or used Turbo T's and T2's.
I really hate cleaning filter bags and had interest in Tiger Shark for that reason. However, it is clear that the Tigershark was pretty slow moving and might take along time to clean my pool. I never could find out to what extent the filter cartridge would be much easier to clean from anybody who had done it.
I strongly suspect from my questions on phone and answer to emails, that the Blue Pearl from poolclick.com for $75 less would likely have been a 2007 because I believe they just forward the order to the manufacturer and do not independently stock it. However, I had no redress if they sent me a 2006 because they never claimed it woudl be a 2007. Not willing to take that chance, after months of toying, I went with pooldoctor to make sure of 2007 model.
The 900$ Blue Diamond on ebay seemed like good deal but wasn't that comfortable buying it in that manner.
I debated alot about the issue of getting a cleaner with a remote. I decided against that because of both price, and hating to clean bags. I figuered I wouldn't want to do a quick spot cleaning because you still have to clean filter bag. So, I'm hoping to wait until needs a full cleaning and that it will clean the whole pool sufficiently. We shall see.
I still wonder about whether rubber brushes might have some advantage over pva for plaster, especailly if also with jets cleaning like Turbo T. However, I wasn't convinced Turbo T had any sophisticated steering computerization, and probaby works like other aquabots. The T2 might, but costs much more.
I'll report back. I just went through all my thought process in case it might be any use to others.
