Dolphin Active 40: the upper-mid Active

The Active 40 sits between the volume-selling Active 30 and the premium Active 60 in Maytronics' US pool-store range. It keeps the 30's full floor-wall-waterline coverage and adds stronger filtration and features for bigger or dirtier pools without the flagship price.

What you get

30, 40 or 60?

Average pool, normal debris: the Active 30 is enough. Larger pool or heavy fine-dust load: the Active 40 earns its step. Big pool, heavy debris, want the top spec in this channel: Active 60. Cross-shop Amazon's Nautilus CC Pro/Supreme at these tiers if online purchase suits you better — the comparison chart lines them all up.

Where is the best place to buy the Dolphin Active 40?

For most buyers, Amazon offers the best combination of price, delivery and returns for the Dolphin Active 40. In the Middle East, Dolphin cleaners are also sold through local Maytronics dealers — see our worldwide availability guide.
