I give the zodiac T3 a one out of five. The slightest debris stops the diaphragm. I can easily fix it but if I am not there to stop the pump and clear the diaphragm then the machine is useless. I bought what I understood to be a superior product only to find it to be basically worthless. The diaphragm design is terrible.
I really am very dissatisfied and disappointed in this product.

The worst product i have ever bought i would never recommend this product i have had to replace diaphrams on my third one now in matter of months its an indoor pool clean and pressure set correct i would say design fault and manufactures probably make more money on spares than selling the cleaners one work to describe these units "JUNK"

Have just bought a new Zodiac T3 cleaner in April 2017. It was easy to set up and is working very well, would not do without it. This T3 replaced my last Zodiac cleaner which worked well for 12 years with only a few repairs and parts. Would recommend the Zodiac T3.

T3 works well enough when its working, would get a good star rating except for the diaphragms. Even though the suction has been adjusted using the pool pulse the diaphragms tear very easy and hard to get replaced on the warrantee.I should have read the reviews before purchasing .

T3 does work well. We have had ours 8 months and today we are fitting our 5th diaphragm!!! The recommended suction pressure was set by a paid pool expert & we have tested it ourselves since. At $50 a pop (at our local pool shop) we are exasperated by the expense. We have previously owned two different Zodiac models and never had such problems. Have contacted Zodiac and was told to check the pressure as that is the probable cause. We think perhaps re-enginering of this part is required. Definitely wouldn't recommend this to other people.

T3 works well enough and would get a 4 star rating except for the diaphragms. Even though the suction has been adjusted using the pool pulse and there are only occasional leaves the diaphragms tear after a month or two. At $40 a diaphragm it is very expensive to maintain. It makes you wonder if that was Zodiacs intention all along.

Always gets stuck...Even Leslie Pools says its a horrible product!!! I would give it 0 stars if I could. For what they charge for this product is ridiculous!!! don't purchase this product. Every pool place I have gone to says the same thing this Zodiac product SUCKS!!!! Don't buy this!!!!

I purchased the T3 in October 2016 As far as I'm concerned it is performing better than expected. I was worried initially after reading some reviews, but it has not faulted. My previous cleaner ( not a Zodiac ) was constantly stopping That's why I purchased this unit . No complaints here. RAY

Done the job, but gets clogged very easily & needs constant attention. With regular use I've found that a diaphragm lasts about 12 months & is ~$45 to replace.
However if you have to contact Zodiac for any reason, I've found that they take 2-3 weeks to reply to each email. In the end I got so annoyed with the company to deal with I threw this in the bin & brought another brand.

My T3 diaphragm lasts one month. It always splits at the yellow part. The suction pressure is set at two way below the recommended pressure. There is a design flaw in these cheap pieces. At $25 a hit at pool supply store, it's time to find a new cleaner. Pool supply store will only warranty the part one time. What are your R&D people doing to remedy this design flaw Zodiac?

I bought our T3 online for a great price. But the cost of replacing the diaphragm is crazy. Splits all the time. You say it's meant for small debris. So how do I keep the leaves from going in our pool? You should put 10 extra in with a new T3 to make up for a bad design.

I purchased a T3 about a year ago. It cleans the pool fantastically and never gets trapped that it doesn’t free itself in a short time. However after about 9 months the diaphragm split so I bought another. After 4 months the new diaphragm split, so I bought another. After a little over a month that diaphragm split. At about $35 for each diaphragm this is getting expensive.

Gets clogged up on the smallest of things. Hoses have started to rot out replacement cost of is $19 for 1 39" section off hose. I think it may be time to buy a new one but different brand. This is the third Barracuda product I have purchased in 10 years.

It constantly gets stuck in corners and tends to land in one place and not move again. Would not recommend it in anyway. Also the diaphragm does not lock in so it tends to break easily. Additionally, once a small piece of debris gets trapped, it will not function properly.

Constantly stuck on the tiniest of seeds. My previous model, the aqua sphere brand, picked these up no trouble and deposited them in the basket. Very disappointed in the T3 which was recommended by the pool shop as a good replacement for my old pool cleaner. Currently back to hand cleaning .

Have had pools and cleaners for 35 years. Built a new pool, needed a vac. Have never had a diaphram cleaner before, liked the look of the T3 so ordered one. I spent many frustrating hours trying to get the thing to keep going but would alway get caught in the corner of the pool, just not worth spending more time trying to get going. I have sold it and bought a much more expensive other brand. Cost more but at least I don't have to waste time trying to make it work. My recommendation on the T3? Keep well clear.
