Hello! I've owned my pool for about 1.5 years now and am still learning all the time. Someone recently recommended I get a pool vac (already have a Polaris 280; they meant a manual vacuum). I see most of the threads in this section are for automatic pool vacs. Can anyone recommend how I should go about choosing a manual vacuum that will do a good job for the lowest possible cost? What other equipment will I need (already have a telescoping pole).
