Hi Farm Boy!
When I lived in South Africa, I had a pool in a Sandton house; basically the plan view of the pool was of two circles, one about 6m, and the other about 4m in diameter - with the smaller of the two intersecting the larger one at around one third of its radius.
Anyway, I had a Kreepy Krauly, and it worked really very well - in the larger 'circle', but would rarely venture into the smaller one; if it did, it would remain stuck there until given a helping hand.:o
This wasn't an issue as the gardener would look after things:)
The house that I later had in Durban was another matter.
Overhanging the pool was a very old and very large avacado tree. When the fruit ripened, there would be the occasional huge 'plop' as an avacado fell ('bombed' would be a better term) into the pool. Poor old KK really got his skirt in a flap over that :eek: :D :D
By and large, though, these beasts, though horribly expensive for a cheap-as-chips set of injection-moulded pieces plus a couple of flexible items, are well worth it, unless you enjoy daily pool scooping, plus weekly pool scrubbing. And if you can get HI to do it, you're a better man than I, gunga-din!
Cheers!
