The cleaner only ever gets stuck if the diaphragm or hose gets a split. These are easily replaced. The one thing I would change is where the two pieces of the head cleaner attach to each other. You line up two plastic tabs and twist - think of a bayonet light globe fitting.

It really should be a screw thread because over time the tabs wear so that the two pieces keep separating.

Only 3 years old and already broken. Not as robust as the original Zodiac Baracuda. Things are less and less built to last! 4 to 5 years life seemed a reasonable life expectancy from my point of view considering the price! Spare parts are also very expensive when available. My last disc has lasted only about a year!

I have owned at least 6 of these over many years. Simple design and very unforgiving. If it stops working the reason is easily rectified. Usually the diaphragm or your basket is full or your pressure has dropped, split hose etc...Of the course the parts wear out but consider the work it does. Remember it sits in salt water 24/7 and does hundreds of thousands of cycles around your pool in its lifetime.
Everything requires maintenance and they are very easy to understand and work on.
Nothing last for ever, and if they did, they would be incredibly expensive. Don’t be too harsh on this cleaner at this price point.

We have only had the cleaner a few years and have had to replace the diaphragm many times. The flow has been adjusted to stop it wearing out so much but this hasn't helped. We now have to replace the hoses as they have all perished. We previously had a Zodiac robot type cleaner for our last pool and even though it was more expensive it did a much better job of getting around the pool and cleaning it. And we only had to replace one of the rubber tyre treds in the five years we had it. I am thinking I will ditch the Aquasphere and invest in a robot style - after spending at least $20 for each diaphragm and now $20 per each hose I have well and truly spent more on parts than the original price of the item.

Purchased 17/06/2015, and in that time it has had three faulty diaphragms, with the problem being a
design/manufacture fault . Replaced under the 2 year warranty but what happens after that time? when it will still
happen. Not happy with this cleaner! As have to travel 85 km to get it replaced.

I am about to order my second one. The first has lasted years(So long I cant remember but more than 5 years, could be 10 +) It eventually wore out where the head connects. Had to replace numerous diaphramns with gum nuts splitting them. Having owned other pool cleaners Kreepy & Barracuda, this is the best.
Its simple and it works!
It does not last forever

Just refuses to circulate and clean checked pump, basket, diaphragm etc'its never run properly 2 months old pool shop refuses to help all he ask what had done and he said adjust the weight on tube but didn't help I give up its set up properly filter, basket pipes pump all correct "who knows ?
Nothing yet
Won't move, suck ect

This design has been around since the 80s (originally as Baracuda, then Zodiac, now Aquasphere) and there's a reason it's still sold, it works.
Very simple design, and i've seen dozens that are 12-15yrs old and still going strong. The only 'issue' is that the cassette chamber and locking ring will eventually wear. I've never seen that happen in less than 8 years though.

They don't like to work in pools with strange shapes etc, no diaphragm cleaner does.
There is a problem with the diaphragms at the moment (a Zodiac problem), make sure you keep your receipt as they have a 12 month warranty.

Otherwise these are great.
reliable, very durable, cheaper than genuine Zodiac
The cassette chamber eventually wears.

Aquasphere Pool Chlorinator purchased it about 3 weeks ago. It worked fine for a week or so and then the control unit died Tried to contact Aquasphere via their website as they DO NOT provide a phone number . Their on line site will not let you in it keeps saying that Australia is not a valid country . Next stop lawyers and or consumer affairs . How can they believe that they do not need to be contactable
