I'm going to tell you my experiences.
When we had our pool renovated, I added a suction side line, well the renovator suggested it, me being pool stupid went with it. They also sold us a Hayward navigator.
The Navigator worked really well, except for large leaves and twigs and acorns.
Every year I had to replace the "wings" $15.00 and about every other year the "feet" about $12.00.
It would clean the entire pool in about 3 hours, give or take.
After 5 years of staying in the pool 24x7 (we don't close here in the winter) it finally was so worn out it cost more to fix it than to buy a new one online.
So I bought "thepoolcleaner" 4 wheel two years ago. Got a close out deal for $200.00.
It does a better job on large leaves, acorns and small twigs. But it takes about 8 hours to cover the whole pool.
I had to replace all 4 tires this year for $60.00. It also stays in 24x7, and other than the tires, have had no problems with it so far.
My neighbor has owned two of those big rubber disk suction side cleaners, both different make, he seems to like them, but they do not cover his pool that well, there are spots they just don't seem to get into for what ever reason.
I liked/like both that I owned, but the cost of the tires on "thepoolcleaner" seems a little too much. But I like how it works better on the leaves, acorns and twigs, so I spend less time this time of the year (fall/winter) unplugging it's suction hole than I did the navigator.
If large leaves, acorns or twigs are not an issue, I would go for the navigator again myself. But that is just my opinion.
