Cathy, My pool is fiberglass. 20'X40' and my dolphin cleans great. I do have a problem with leaves and normally use a leaf vacuum first. Large amounts of heavy debris does seem to cause problems. I added a link below for the leaf vacuum,it will work fine on your acorns. My dolphin climbs the walls and goes up the steps. Do you have the remote control? Thats how I set the peramiters for how it cleans. The only problem I have with my dolphin is when I lift it out of the water it drops a small amount of debris. Good Luck, Mark P.S I live in Louisiana and have used it in all weather and water temps without any differance in cleaning. I also use a salt generator Here is a link that might be useful: leaf vacuum

I bought a T2 when it first came out in 2005. I have a free form 40x38 pool with water features and rocks in the pool. The T2 did an incredible job cleaning the pool and was extremely fast. It could clean the entire pool in about 4hrs. Unfortunately it was also a maintenance nightmare. I think that thing never went more then 6months without having to be sent in for a repair. The Aqua-bot company always repaired it at no cost, but the whole process meant going without a cleaner for about 3weeks. The T2 made it to August 2008 before it finally burned out its motor after just 3months out of the shop to have the pump replaced. It was at this point that they owned up to the fact that the original T2's had some serious design defects in them. After going back and forth with them over the amount of services issues I had, I ended up getting upgraded to the T4 at a nominal cost. I have to say the T4 is light years ahead of my old T2 and can clean my pool in about 2hrs. I love having the remote and actually do use it for spot cleaning and cleaning under my waterfall on the sun-shelf. Here are what I see as the big + and - of the T2/T4: Upside: + It cleans the pool very fast (I would assume faster then any of the non-robotic cleaners) + The company stands behind their product (so long as you buy from an authorized dealer) + The cleaning job is incredible and you will probably never see a cleaner pool then one cleaned by a robot. + The hose rewinds very easily and never gets twisted up since it floats on top of the water. + It stows away very easily. + It has no problem with a large free form pool with obstacles. + Remote for spot cleaning (T4) + Climbs walls to tile + Filters water + Great wanrranty. Downside: - The power supply is water resistant not water proof which means you have to make sure its protected in case it rains. -Set up and tear down can be taxing. If you are the type of person that leaves the garden hose unwound after using it, don't buy a T2. - When it breaks you most likely will have to package it up and send it back. You need to manually clean the pool while its gone, so don't throw away your vacuum. - You need some basic mechanical skills to change the belts and tracks once every year and a half. - They are very expensive compared to non-robotic cleaners. - If the pump seals blow, you will have a small oil slick in your pool for about a day. - When the warranty runs out, the parts are very expensive

Thanks for the input. Kurt-Thank you. After I read that article about San Juan pools making coloured pools, I contacted our PB. He said that San Juan has stopped making the coloured pools due to fading from salt systems. He said that Leisure's warrantee on the gel coat says it does not fade, but since he has not personally seen a Leisure pool after 10 years, he can only go by what the manufacturer tells him. So we will probably be sticking with the light blue like you. Sharla-Your pool build pics look great. I will have to look into that pool cleaner. We currently have a Kreepy Krawly in our old pool and we find it does the trick with that, but maybe we should look into an upgade for the new pool. love2weed-I love the colour of your pool. It is so pretty. The water colour is so peaceful. We are hoping to achieve the same look with our concrete decking too. I wish our PBer did Viking. Thanks for sharing. Here is a link to the pool model we have chosen from mypoolspace.com It is the Manatee the size is 32'10'x14' with a deep end of 5'10' and a shallow of 3'6'. We are not putting in a fountain or waterline tile on ours. This model is white too. http://www.mypoolspace.net:80/?module=photo&action=zoom&ID=4047

I hate to say this but this happened to us last year and the issue was answered extensively. The subject was "Grossed out & Disgusted" and this is the link - http://ths.gardenweb.com/forums/load/pools/msg071419062694.html I went overboard and shocked the pool, keeping the free CL at 12 for 72 hours. I then backwashed the DE filter shocked it again to achieve free CL of 12. I waited until the CL dropped to 4, backwashed again, and finally opened the pool. This happened to us in early August and was not how we had planned on spending the hottest part of summer. Good Luck and PS, I had managed to forget this incident until you reminded me.
