Bought my CX20 Jan2017, stopped working just after 1 year (vacuum worked but stopped moving) sent it back to Zodiac for repair under warranty, their cost) all good. 2 and a bit years after purchase the thing stops again, runs for a minute then the fault light comes on and starts to flash, robot dead in the water. Of course it is now out of warranty. Email Zodiac 4 times, no reply, tried to call them no return call. So I get on their website and find out that they have a repairer listed close to me. I call them and they tell me that they cannot get through to Zodiac most of the time. Anyway, drop off the robot at the repairer today 30/10/19, lets see what comes out of this.
I repeat, DO NOT BUY A ZODIAC ROBOT!

Machine never really cleaned well - even with the higher grade micro filter leaves fine dust.
Then stops repeatedly. Needs to have electrical plugs cleaned constantly else will stop and flash.
Finally pins in plugs corroded. Can't get any satisfaction from pool shop or zodiac to fix.
Looking to have electrician mod with a marine grade plug.
Zodiac woman said they don't speak to the public on their customer service line- seriously.
Never ever ever buy zodiac

Bought on 31st March 2016 and developed a fault well outside the warranty period. After discussion with the NZ Zodiac Manager the problem was resolved to our total satisfaction. Couldn't have asked for a better solution. Highly recommended

Was great through its first summer use. Now doing a winter clean it's going 1 direction only. Won't go up the wall and won't change direction. Just sits in the corner running in the same spot. It's clean and tracks are working. Still under warranty so hopefully it's fixed. I'm extremely disappointed in this product playing up so soon especially when I read others reviews but continued with my purchase stupidly. My advice is stay clear of this product and listen to others advice like I should have. So Zodiac I look fwd to hear how you will rectify my situation

The cx20 was great initially, however we had to send it for warranty repairs when it stopped working entirely. At that time we also advised the tracks kept coming off during use. The machine was returned and worked, however the tracks weren't replaced and kept coming off. The unit broke again on the weekend - no power to the control box at all. It is now out of warranty so now we will be up for buying a new control box and hoping that is the issue, but if it isn't, we will be stuck with the cost of a new machine. I bought it in November 2016 and hoped it would last longer than it has, considering the high cost of the unit. I won't buy another zodiac.

Was a good machine but then It died just after warranty. I spent $400+ dollars and a $99 fee to a “supplier” to have it fixed only to die 6 months later and be told their repairs are only guaranteed to last 3 months. This machine was not used excessively I would have expected more from something for this price.

We brought this cleaner back in January 2016 and it worked perfectly for fourteen months and then the info light came on and it wouldn't do anything. We returned it to Zodiac and they fixed it under warranty. The light came on again last week and when I phoned Zodiac they said that the repair was Over a year ago and so was was not covered by them. I would expect a product that costs $1000 plus, and is used only twice a week in the Sydney swimming season to last a bit longer than just over three years. If only Dyson made pool cleaners!!

Only early days but the Zodiac CX20 is working as intended. Cleans pool thoroughly in about 2 hours. Climbs walls and steps comfortably. The unit is easy to clean, maintain and operate. Would recommend at this stage.

I have the zodiac CX20 - bought in September 2016
Broke down and needed to be repaired in Jan 2018.
Now needs to be repaired again as has the same fault.

The fault is that I start the pool cleaner and it will start for a couple of seconds then stop with the error light flashing.

Seems to only last just over 12 months and needs repair - I have emailed apac.technicalsupport for assistance again.

UPDATE
Called Zodiac - they repaired it for me.. Service was quite good. Anyone with issues i recommend call the 1300 number ...

Tracks come off on sharp step edged. Does not clean rounded corners. It also has trouble covering a thorough clean pattern.

Purchased the CX20 Oct 2016 and it worked perfectly well. Very pleased with it but not until yesterday we tried to use it and it goes for a bit then suddenly stop, then it seems it is trying to move until after a few minutes it goes again for a few seconds then stops again. I hope zodiac can help us out with this as it is just outside the warranty period and we can't afford another 1k at the moment.

Had this unit for 3 years, the first two seasons it worked well and now when it's turned on it runs for 10 seconds and stops!! Of course it is now out of warranty!! Considering it was nearly $1k you would think it would last a lot longer than it has.. Very disappointed, I hope Zodiac can help!

We have had our CX20 for nearly three years now. First two years fantastic, best cleaner we have had. We had an issue with flashing control box 1 month prior to 2 yr warranty end. Returned the unit to Zodiac and they repaired and returned within a week. Just one year later (last week) we had a second issue with the flashing controller box. The unit was just 12 months since its last repair. Rang Zodiac support (all be it the wait was long) the team organised a repair agent to visit our house. He came, repaired the unit and now back to working like a charm. Cant speak highly enough of the level of service and the no issues approach to just in or just out of warranty these guys take.

I’ve only been using this cleaner for a few weeks but very impressed to date. I purchased the optional 100 micron filter basket as our pool is more prone to fine dust rather than larger twigs and leaf litter. Does a great job and very easy to empty and clean.

Worked well but only just out of warranty and stopped working ( as live in Tasmania it prob has only been used 6-9months in total). Contacted company by phone found the team member quite dismissive and rude. Took to local pool shop as advised and has been told by zodiac it is discontinued and no parts available to fix motor. Very disappointed
