Onga Hammerhead

I have had an Onga Hammerhead pool cleaner for a while now and it is useless. It never sits flat and continually gets stuck at various points around the pool. I have a kidney shaped pool. I have tried altering hose lengths, moving the weight around and still nothing. Would not recommend.

I have a half kidney half rectangle concrete tiled pool it is surrounded by a large amount of palm trees also trees .I purchased the onga with deflector to stop it getting stuck after reading reveiws 10 saying great 10 saying junk .I have to say I am happy it picks up everything without fuss .previous cleaner was $99 ebay special heap of junk that I didn't purchase.purchased the onga from pool and spa warehouse with in line leaf catcher and hose for $329 bought deflector separately. Very happy for the price.

Bought it to replace my Polaris, which needs its own pump and controller regularly got stuck or just didn't move at all and needed its expensive mesh net cleaned and periodically replaced.
So far in terms of cleaning the Hammerhead been absolutely great and the the 'dust tracks' that left by the Polaris have essentially disappeared. The cons are it sometimes gets stuck in one right hand corner and momentarily sucks air, and also it seems to produce very loud 'hammering' on our pool surface (quartz). Any advice in this regard?

This can't sit flat on the pool. Change number of hoses, weight distribution etc. Piece of junk and no help from my previous review. So frustrated. Should pick up leaves and dirt but doesn't. I would also like to thank the makers of this for not taking time to answer what should be a concern to your product. This has been on this website for 2 weeks + and no reply. Pure class.

Purchased this to replace my Aldi one that died after 4 years. Garbage. Doesnt pick up dirt nor leaves. Doesnt sit flat on pool floor, despite trying every option with weights and house length. Connections to Skinner box all poor, just vibrates off. Gets stuck on stairs and in corner. 4 times price of Aldi Force but useless. Will bin it and try buy the aldi one when it comes on sale.

Seems to stay in the same corner of the pool no matter what. And the back is heavier than the front so the round pad isn’t flat to the ground. All the parts seem sturdy and strong. Just wish it would move around the pool. Not sure how to fix it.

Replaced my old Zodiac Genie 2 with this a few weeks back and very impressed so far. Has run for 8 hours a day faultless so far and has cleaned the pool very well. I like that it does not have the diaphram that most suction cleaners have which is one less piece to replace and should hopefully allow small gum nuts etc to pass through without affecting the suction. For the price so far with a 3 year warranty I am very glad I stuck to this simple design rather than spending big $ on the fancy new types of cleaners.

The hammer head worked really well for 6 months or so and now ends up on its side every time and does very little cleaning. Have done all the problem solving perhaps I should return it to the supplier?
Has anyone really solved this problem / yes the head is free / weights and pressure make no difference

Without doubt the best pool cleaner I've had - Just goes about the job of doing was it was purchased for. Despite leaves, seeds etc it goes about the task with no issues at all - So simple its hard to believe and really makes the old Zodiac G4 totally antiquated ( and super expensive in parts as well )

Read the reviews and agree with others its the best cleaner out there

Best Pool Cleaner I every had. Love the fact that it is almost silent the most about this cleaner and it has lasted many years. I couldn't find the receipt to verify how long I had it but I am guessing at least 5 years. It is now time for another one and I get the same again. The hose is starting to develop holes at the joints and elsewhere and the base is also worn quite a bit from years of crawling on the pool surface.

Returned to pool shop and updated to the Rebal model.
They told me that the Hammerhead is a cheap cleaner for the online shops. Rebal is the best cleaner I have had. Doesn't get stuck and covers the entire pool. The hammerhead kept getting stuck and jammed. Looked cheap and Chinese.

Have owned the hammerhead for a couple of years now and it has been by far the best pool cleaner to date. Unlike some other more expensive cleaners we have previously owned, there are minimal moving parts, which means there is very little that can break. We have a slightly curved fiberglass pool and the hammerhead gets around it without problem ( the only exception being the set of steps). It was one of the more budget cleaners when I bought it, but it does exactly what it's meant to, so is very good value. Our pool is approx 8.5m by 3.5m.

After owning a full robotic cleaner with not great results we bought a hammerhead
It cleans all the walls and most the stairs
It’s able to pick up gum leaves and nuts
We have loads of very large trees around our pool and nothing has stopped it yet.
It hasn’t got stuck or stopped.
I was a little bit sceptical buy a lower cost cleaner and I am so glad we did.
I can’t recommend this cleaner enough it’s fantastic in all ways and the best price @ $295

I bought this product in late June 2017 and it has worked really well. I used to have a Zodiac but it stopped with any size nut. That has not been the case with this and I have waited a few months since buying to see how it has handled lots of leaves. It's done really well and only occasionally have had to clear the head because a branch has fallen in but it still goes. I'm really happy with this product.
