So I bought a MX8 over the past weekend, however it doesn't climb the walls. I found a few issues and had the pool repair people here today. The guy cannot confirm if the unit should climb the walls. On the Zodiac website it says it does... I then phoned the support and was told it might not be able to climb a tiled pool...

Anyone have one of these and confirm it can or cannot climb? I'm getting close to returning it to builders and getting something for R900 instead of R2500.....
 
MX8 needs good suction to operate ..

I gave up on mine eventually and bought an El Cheapo Voyager --- works well.
 
My MX8 nearly climbs out the pool. But it's marblite, not tiled.

Check your suction, as mentioned. There's something in the mx8 manual about it, something about checking the speed of the wheels...

I purchased the baby MX6 model - works very well and yes it climbs the walls. It all depends on suction I assume. You may wish to contact Zodiac directly for assistance before returning it.
 
I'm very close to doing exactly as you have done. The pool guys just need to come back tomorrow and connect a few things, then I will return it. Lost the silly slip, so now I need to get bank statements for builders.

I did and they told me they have problems with tiled pools... but the product info says its good for tiled pools.

Well ours can't climb the walls of our smooth fibreglass lined pool despite having good suction, so I doubt it. And it gets jammed regularly by just a few leaves. The only good thing about it is that it covers the pool bottom very thoroughly without missed spots due to it's mechanical direction switching.
 
Mine gets to the side and then it keeps slipping - I can see the wheels turning.

I have now spoken to two customer support people from Zodiac, and both confirm that if the pool is tiled there is little chance of the unit climbing walls. I assume if I had a beast of a pump it will do it, but my pump is rated 750W.

I'm taking the MX8 back tomorrow, what should I get in its place?

Hi, have you considered one of these? Dolphin - quite pricey though!

Probably too late for you, webdev, but ... one thing to bear in mind is that a new MX-8 is usually a bit "tight" and takes a little while to loosen up. I had the same experience when mine was new (didn't quite climb walls), but it reached peak performance within a week or two, after which it moved more quickly and climbed walls well.
I have a fibreglass-lined pool with a Quality 0.75kW (output) pump and my unit practically climbs out the water. Occasionally it will lose traction on the smooth fibreglass when it nears the surface.

The same is true when the unit has been recently serviced - it takes a while to loosen up.

less than 24 hours with my MX8 and my 15 year old genius is back in the pool. Even busted to where the parts required to repair it justified buying a new cleaner its working better than the MX8.

After a short conversation with Zodiac to get if I'm missing something. They recommended I take it back and get a refund. (probably a new genius or whatever its called now)

It got stuck on diabolical things like small twigs and grass dropped from a weavers nest that would wind around the paddles. My primary reason for buying was to be better at clearing debris. leaves / dates from a palm tree / grass from a weaver that might be the worst nest builder in history.

Customer service recommended I take it back asap for a full refund.

Now aside from getting stuck on the things I had hoped it would be better at, its a nice machine, the random way it moves meant that it got to places my other pool cleaner never even saw. It is to be noted that my pool runs on a small motor and a consideration for me was to put a bigger motor of to see if would do better. With my 750w motor it moved rather leisurely. It coped fine with leaves and smaller things like nuts about the size of a pea filling the basket quickly when hitting the patches the genius didn't.
 
The MX6 would have been better on a small pump. But yes, it will get stuck on palm leaves and long pieces of grass like from a weavers nest.
 
Thought about the MX6 and less moving parts to need power.

But like you said it wont cope with the other bits, they did talk about the dominator.
But my last experience with Kreepy Krawly was when your choices where a hose connected to a brush on a pole or a Kreepry krawly you had to push around whit the pole.

The Barracuda has honestly been very good and I probably spend about the same time on it per year than on the new one in the last day.

Are the new no name ones as good or nearly as good as? something you could recommend for my biggest problem the tree fruit. they're a Little smaller than a ferrero rocher. so just small enough to fit into the throat of it and big enough to block it. A 20% larger diaphragm would not get stuck.

My experience with the geared pool cleaner was not great but still I see the appeal of it and why its popular.

Yes, long strip leaves (like palm fronds) are its Kryptonite, tending (as you rightly say) to get wrapped around the shafts.
As (bad) luck would have it, I only have palm trees around my pool, although fortunately not that many.
Fortunately I find it to be fairly tolerant of them, in the sense that it keeps on running for quite a while even with a few in place. When I open it up to clear it (or for a full service), I'm often amazed that it's still been able to keep running with so much crud tangled up inside it!
That said, the MX-8 is very dependent on good suction and decent flow rate.

Yes, in terms of coverage and the short time in which it effects a good clean-up, it is unmatched, IMHO. It also never, ever gets stuck in one place.
My previous Zodiac X7 Quattro tended to clean a perfect "figure 8" and always used to get hung up at one particular corner of the pool where the steps met the walls. But it was far lower maintenance.

Yes, that it does.
On this point, it's worth noting that the yellow plastic insert in the throat on the underside of the MX-8 can be removed to give a significantly bigger opening. This is not made all that clear in the manual.

Talk of the devil... I looked outside and my MX6 had stopped working. Opened the lid and pulled a long leaf out but it still wouldn't work.

Had to take the engine part, which I have to do every few weeks. I thought I would share some images in case anybody wonders what is involved.

Notice the leaves wrapped around the shaft:

Another view:

This is what I removed:

Took the thing back to the pool and it still would not work. Then I noticed a leaf under the bottom part of it, and had to take it apart again to remove the bottom turbine, which I have never had to do before:

So... at the end of the day this thing is not magic and does require maintenance, but it's the ONLY pool cleaner that works in my pool. I've tried 6 different brands over the years, and this is the first one that does not just clean in a figure of eight and/or get stuck. The MX6 cleans everywhere, and works great as long as I get to any long leaves before it does.
 
Hehe, well done mister !

Just for interest, here are some pics of the (virtually identical) MX-8 situations.

A few palm fronds always get wrapped around the turbine blades, and some will find their way to the outer shafts. Most can just be pulled out by hand, but occasionally you'll need to undo 8 screws to remove the turbine casing, lift out the main drive shaft and clear everything fully:

Taking out the two "sweeper disc" assemblies (just one screw each) will usually reveal a few fronds wrapped around the outer sleeves and at the bottom of the inner shafts :

... but stripping the shafts and bearings out of the sleeves will reveal some more "internal entanglement" :
IMG-20151024-01717 (Large).jpg

Apart from clearing leaves from the turbine as and when needed (ie if/when the unit stops), I find it helps to do it about once every 2 weeks anyway.

I find the further step of clearing the sweeper disc assemblies is necessary about once every 6 months; pulling the sweeper shafts out of the sleeves about once a year. I avoid doing the latter more frequently as it puts a bit of stress on the Polaris plastic bearings.

So... at the end of the day this thing is not magic and does require maintenance, but it's the ONLY pool cleaner that works in my pool. I've tried 6 different brands over the years, and this is the first one that does not just clean in a figure of eight and/or get stuck.

^This!
