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.

Replaced our old Kreepy Krauly with a Hammerhead (concrete pool) 3 weeks ago. Works perfectly straight out of the box. Just had to set the suction pressure with the supplied device. Didn't need to add hose weights or make any other adjustments. The first thing I noticed is no more jack hammer noice, just silence. This alone was worth changing from the Kreepy. But also the Kreepy used to get stuck in the corner at the steps several times a day and choke on long leaves and nuts from the palm trees. Not had either of those problems with the Hammerhead, not even once.
Very happy!

I live in a treed area nd used to own a krawly one. After dozens of diaghrams and continually having to remove stick and large leaves the got stiuck i bought this one. In 7 years it has not missed a beat. About to replace the skirt for the first time It eats leaves sticks and anything else that falls into the pool. Great low maint cleaner

We have used our Hammerhead for 3 years and it has been reliable and done a great job of cleaning the pool. We will be replacing it shortly because after three years of constantly being in the pool the plastic has started to break down. We replaced the skirt twice in three years with genuine parts and the replacement skirts didn't last very long. That would be my only complaint.

All of these pool cleaners that have an opening that opens and closes are the same. Leaves get halfway through the opening then the cleaner stops & you have to unclog it. If you have to buy one of this type, buy the cheapest cause you get nothing more for spending more.

So far, so good - swapped from my Barracuda G2 (which was admittedly falling apart, and had worked well enough in its earlier life) to the Hammerhead based on reviews - and sure enough it is a effective and doesn't get stuck. There are plenty of more expensive cleaners, not sure why you would need one

After trying various brands and models I can safely say that the Hammerhead is hands down the best unit I have owned. After correcting the suction flow to suit the hammerhead i.e. maximum my pump can handle by removing any losses, I have a spotlessly clean pool. The hammerhead climbs the walls and all of the stairs in my 10M lap pool. I could not be happier. I have read that some owners have had problems with theirs, to which I can only say that I have not! I have had it now for 8 months without issue. It even manages to remove the palm leaves!!

My Kreepy Krauly had given me grief for years and it was time for a change. The Onga Hammerhead was cheap so I took a punt and have been really happy with the results. Had an issue fitting the unit to my existing skimmer plate but after buying a new plate has been working beautifully. The sound of my Kreepy was keeping the neighbours awake so that was the biggest surprise. The Hammerhead is silent! Cleans better than the Kreepy and has not yet stopped working.

wow this thing is great the mako shark is called the Kreepy Krauly Kruiser in the USA, made in europe and not china so is a good bit of kit for $395 the hammerhead is a great pool cleaner But i think the Mako is better bought online from Dads pool shop, time will tell but so far so good with my Mako shark from pentair.......

Having lived with the frustrations of Zodiac cleaners (thesight of a banksia leaf and the Zodiac would stop), I am absolutely delighted with the Hammerhead. It will do pretty big leaves and small sticks. I was away for a month and for the first time EVER the pool was fine.

When you look at the function of the Cleaner it should be perfect, it is not. The smallest leaf stops it. The smallest nut stops it. Returned it three times to where i purchased it at Blacktown and told that it was in good working order, must be pressure, must be air .
Quite simply the hammer mechanism binds up on leaf matter and the unit stops working. Most frustrating pool cleaner i have ever owned.
Back to the maple matic again, working like a charm. My advice don't buy the hammer head. to much to little can stop it.

I replaced my Quattro7 with this cleaner and I love it. It has been very reliable.
Never gets stuck anywhere.
I do have an odd shaped pool and there are a few spots it does not clean, but this is the only drawback.
Price was also much cheaper than previous pool cleaner.

Had one in last house, pebble finish surface, worked brilliant, so purchased one; new house and tiled pool with large radius corners, cleaner gets stuck everywhere, driving us just mad. Can't get traction, on tiles, added weights, to suction head, helps a little, tried every thing, had a couple of pool guys round but couldn't improve it.

Bought 2 months ago, and it got stuck the first few of times, always in the same place, but since then it has chugged away nicely without fuss. Why it got stuck initially, I don't know - I didn't make any adjustments. I might get another hose length; it's at full stretch in my 8m pool.

Just does the job properly, the walls the floor, never gets stuck, doesn't miss anywhere, It's always clean with no algae growth thanks to the Onga
I have had 3 other pool cleaners over 20 yrs, always disappointed and had started to clean the pool manually, I think the onga saves me at least 2 hours per week, that's 100 hours per year = 2.5 working weeks.
My pool is a rectangle 12.5m x 4.8m with slightly curved corners. It has a pebble crete finish.
I've never felt compelled to write a review before, The Onga just far exceeded my expectations!
