Is there something unique about floor cleaners that reduces the need for brushing?
Do you like the choices you made for depth (sport style with the deep center)? Also, you have just a little bit of decking around the pool has that been a problem?
Brushing is still a good idea as it helps dislodge any algae that could be trying to get started.There is nothing unique. Their purpose is to clean the bottom & remove the debris via the drain. This generation does it so well that brushing the bottom is redundant. Still brush the sides.
Regarding the decking - are you happy with the amount of decking you have? Since I see you have decking on 2 sides only - with the larger decking area at the end of the pool where your loungers are in the pictures.
The Baja step entry acts as a wet deck area. The decking amount is perfect for us. You can sit on the one side & exit the pool easily plus we have 2 sitting ledges at two corners. We additionally have two sitting areas: one is a covered patio & the second a raised patio with a sail shade. We feel we don't need decking on the other 2 sides.
