It took me a few years here to realize that raking can be futile as it tends to stir things up more than clean things up. So I purchased a regular pool ‘rake’ - but just the net part. See below link for what I bought.
Soon as the water hits 65 and I have a calm day, I’m in our swimming area with mask and snorkel using this to skim along the bottom. Unlike a normal rake, this captures almost everything and doesn’t stir things up much. So, except for occasional touch-ups, I’m good to go for the season. While we’re fortunate that the currents don’t feed us a constant batch of new debris, I found this to be much quicker and more efficient than raking.
The net I bought is quite durable and I think it comes with a lifetime replacement guarantee.
