MEDIUM MESH NET :
Fine mesh pool leaf bags grab tiny debris from the swimming pool bottom and surface, but the tight weave "pushes" a lot of water, meaning more muscle strain for you and more difficulty catching large debris like leaves. It can grab everything except silt ,sand and does NOT "push" the water. So less physical strain for you , larger, lighter debris is NOT pushed away from the net.
DURABLE NYLON NET:
A tough nylon skimmer net is less likely to develop holes and easily collects large volumes of debris. It won't pass back "through" the rake frame, allowing the contents to spill out.
ALUMINUM FRAME :
Aluminum frame leaf catchers are slightly heavier than plastic, but handle is more weight. You can empty the net less frequently, resulting in less time pool cleaning. They cost more, but you get what you pay for.
Its Curved sides won't scrape debris from the pool-side very well. Straight sides ride flush against the pool-side to remove stuck on leaves.
FOR ALL POOLS:
This Professional Grade aluminum leaf rake can be used on all pool types to collect dirt, leaves, debris, and more from walls, floors and surface of the pool. This one piece aluminum body has curved edges, no sharp edges. Fine mesh netting collects the smallest debris. Also, features soft touch, quick disconnect, fits most telescopic vacuum poles.
POLE NOT INCLUDED :You'll need a telescoping pool pole with 1.12" inner diameter and holes for butterfly or v-clip attachment.
