Want more robot for your money? A certified refurbished Dolphin or open-box unit often gives you a step (or two) up in features for the same price — with authorized-dealer warranty support, a 30-day trial, and $0 restocking. It's the smartest way to shop by budget.
Shopping by budget is smart — but the cheapest robot isn't always the best value. The trick is knowing what features you actually get at each price, and where a certified refurbished or open-box unit lets you buy far more robot for the same money. Below, we match real Dolphin value to your budget honestly.
A certified refurbished or open-box Dolphin often delivers a step (or two) up in features for the same price as a new entry model — with the same warranty support when bought from an authorized dealer.
Fine (Nano) filtration is worth stretching for if you have pollen, dust, or silt. Below a certain price it's an upgrade, not standard.
A durable robot with a real warranty beats a cheap one you replace in two seasons. Factor warranty length and build quality, not just sticker price.
Only authorized dealers offer the full warranty, 30-day trial, and $0 restocking. Ultra-cheap grey-market units often void the warranty.

Match the robot to the job
Under $500 buys a genuine entry Dolphin new — or a refurbished mid-tier model that punches above its price. Prioritize suction, coverage, and warranty.
The Dolphin Nautilus Pool Up is the standout value new — powerful suction and real robotic cleaning. For an even bigger step up, look at a certified refurbished Cayman near this budget.
Usually as an upgrade rather than standard. The Nautilus Pool Up and Cayman accept finer filters; if fine debris (pollen, dust) is your issue, budget for the upgrade or a refurbished ProLine model.
If you want maximum features for the money, a certified refurbished mid-tier Dolphin often beats a new entry unit — same warranty support when bought authorized.
