Hayward AquaNaut 450

Rolls on its side – Needs to include an instruction booklet with the unit with a troubleshooting guide so that any initial problems can be worked through. The unit needs to be tweaked and balanced before it works

Keep your money – Device needs constant intervention. Always sits at the base of the wall while my pool floor requires manual vacuuming. I have replaced all 4 wheels and that seamed to remedy the issue but looks like after 3 months I would need to change the wheels again as I am again manually vacuuming the pool. Stay away from the brand

Useless, over-priced lump of plastic junk! – We purchased a new Aquanaut 450 from our pool builder 7 months ago. It has been almost completely ineffective. As I right this review, the Aquanaut is jammed up against a wall in the deep of our pool where it has been for the last 30 minutes. It either gravitates to this position or falls on its side and stays there. It cannot be left running on its own without my intervention every 20 or 30 minutes minutes to right it, or relocate it. It never cleans the shallow half of the pool. I have wasted too many hours of my life trying to tune the Aquanaut. I've communicated with Hayward Australia directly and through our pool builder. I have repeatedly checked the RPM, tried all 3 inlet throat sizes, ensured that the floats are in the correct position, and changed the tyres. It is now fitted with the white tyres recommended for pool surfaces with a high glass content. Nothing works. If I want to vacuum our pool properly I have to drag out the old manual vacuum head. Hayward should really be ashamed of selling this piece of rubbish when they know full well it doesn't operate properly on many modern pool surfaces.
