We purchased the Zodiac T3 pool cleaner in May 2018. Now, we have only used it for less than a year and the diaphragm has broken. Since we got it, we have started to take its nightmare every day. It doesn't surround the pool, it's very low power, and it stops so often doesn't matter how you change the power choice anyway. Now our swimming pool has grown up a lot of green algae. It has brought us so much trouble. We do not recommend anyone to purchase this item at any price.

Cleaner works well until the diaphragm splits...just below the yellow reinforced section. If sounds like a common problem, costs
Almost $40 to replace each time. My recommendation is to go with a different cleaner as we have spent over $150 in the past 18 months replacing this poorly designed product. I would love it if zodiac could replace my cleaner with a different model of provide me with an alternative diaphragm that will rectify this reoccurring issue.

The twist and lock hoses that come with Zodiac T3 cleaner appear to be of very poor quality and do not meet Australian conditions as the hoses have only lasted 2 years and now are all disintegrating and need replacement.. They are very expensive to replace with prices for 10 x 1 metre ~ $150 +/-.
If I had found previous reviews of these hoses I would not have bought the Zodiac T3 pool cleaner.
These hoses are proprietary and you are stuck with using them unless you cut your costs and get a no name cleaner that uses standard hoses.
Beware of these hoses unless you want to pay through the nose to replace them every 2 years.

diaphragm splits every couple of months, even with the spring on the head at the lowest suction setting would be good if the diaphragm lasted, it gets stuck in the corners too but when new the suction is good probably cheaper to just buy a generic one from bunnings instead of always replacing parts

Cleans leaves from the pool no issues, overall happy, but needs better diaphragm, given this is where the cleaner has to work the hardest, does not get in the way when swimming, leaves pool lovely and clean when in use, shouldn’t have to replace the diaphragm on a regular basis though

This cleaner is fine in our concrete pool, goes everywhere, up walls, along stairs etc. The only issue is with the diaphragm design. The yellow T section is fuse moulded into different material leaving a much too thin join. Being that this is the hardest working part,it fatigues at the bottom of the T and ruptures. This is the weakest link and severely lowers the working life.
12months in and I’m on to my second diaphragm. The old design lasted a lot longer.

I have had this unit for about 15 months, it gets stuck in corners regularly I have replaced the diaphragm 4 times I've just ordered 2 more. At this rate its costing more than a complete set up!. There is no branches or leaves going in the pool, surely there must be something Zodiac can do to improve the unit?

I agree with all the other poor reviews of this product.
We've had our for about 2 years now but this cleaner has driven me crazy from day one.
I have to clean it out every day as the smallest leaf stops it working.
The hoses also tangle continuously and need to need to be straightened everyday as well.
We are on about our sixth diaphragm too.

This product is rubbish. I've had to replace the diaphragm so many times since I bought it, I've lost count. Surely Zodiac can see this as a major design fault, with so many complaints. If it was a vehicle there'd be a recall to replace the part. Myself and others will be taking their business away from Zodiac as I believe the newer models also contain the same diaphragm.

Good cleaner when it is working but you only have to look at it the wrong way and the diaphragm busts open.... considering a single diaphragm is about one fifth (1/5) the price of an ebay cleaner kit (which includes hoses and spare diaphragms) why would you buy this heap of crap?

i actually won an R3 from a poolwerx competition today, i had been eyeing one of these off for a year or two when going in to get my water tested and was over the moon when i got the call saying i won one, took it home, set it all up had the suction set at the 21/2 as stated in the brochure, and it works for a while and then stops, then gets stuck in the same position in a corner of the pool and found myself today constantly going out to see if it was still working or stuck in a corner, i ended up just dismantling it and tomorrow i will put it back in the box and sell it on buy swap sell, lucky i didn't spend the money on it because i would have been really disappointed.
would not recommend at all

Having used the G3 previously I was very disappointed because the T3 keeps getting stuck with gum nuts n any small debris. I belief it’s the design of the diaphragm because it’s got ridget sides and it makes it difficult to let debris through. With the cost of replacement I have no choice but to cover my pool with the blanket. Hope zodiac can help me solve my problem.

I have found this product to really have a mind of its own, there are days when it just purrs away and does it’s job quite well, the next I have to shake and bump the cleaner every few minutes to get it to start pulsing again, The suction is always around the recommended 2.5 to 3. There are times when it will just sit there doing nothing then the next moment I look up it’s working fine. It has used about 3 diaphragms in the last 4 years, not cheap at around $35 although it is a relatively easy job to replace. The cleaner when it works does a good job even climbing the walls although it can be stuck in corners occasionally. Would I recommend it to family, not sure. It works more than it doesn’t but can be a frustrating tool at times.

I am a 2 pool owner and own 2 barracudas, one for each pool. Yes the diaphragm does not last for 2 years, so order one online for less than $10 and get over it. Yes you can spend 45 or more at a pool store......I order 3 online so I have a few spares. 2 pools and 2 barracudas. I couldn't be happier. I have had one of my 'Cudas since 20o1 and the other I got for the second pool in 2012.

Replaced my old cleaner of 6 years with T3 and was initially happy with its performance but then like everyone else,the diaphragm failed. I was told to check the suction and it was correct at 2.5. Since then I've had to replace the diaphragm two more times and to top it off two of the hose segments have split-a very expensive exercise.I don't think this is good enough for a product that is only 18 months old.

The system itself works fine but the diaphragms split/tear often. Anywhere between 3-6 months the unit stops and it is ALWAYS the diaphragm. It always splits in the same place too. Weak walls I think. Should improve the quality of the diaphragm. I can see having to replace periodically but not on a routine basis. We have also had to replace the wheel deflector, washers, etc but in 4 years I estimate we have replaced the diaphragm at least 10 times. About to look at a different cleaner. It starts to add up

Bought it in July and have had to replace the diaphram twice. The first time it took 4 weeks to get a replacement finally Club Piscine Joliette took one out of the floor model now it it is cracked again. Must be a defect in the diaphrams as there are so many reviews about it.

I replaced an old model with the T3 and was very happy for a while, but it has cost hundreds in parts replacement each year. While the unit looks like only a couple of parts, there are many and all have to be periodically replaced. It is constantly falling to pieces in the deep end of my pool, no matter how hard I (or my pool shop) try to screw it together. It cleans well when it is working, but the bits do not stay together. Sorry but this model is a lemon. Other family members have different cleaners without having to constantly replace bits.
