TigerShark vs Dolphin Pool Cleaner: Which Should You Buy?
Hayward's TigerShark and Maytronics' Dolphin are the two names pool owners compare most when buying a robotic cleaner. Both are proper robotic cleaners — self-contained, pump-independent, with onboard filtration — but they take different approaches, and for most buyers in 2026 the choice is clearer than it looks.
The short verdict
For most pools, a Dolphin is the better buy. Maytronics is the robotic-cleaner specialist — it pioneered the category in 1983 and iterates fastest on navigation, filtration and app control — and the Dolphin range simply offers more choice at every price, from the Nautilus CC to the M700. The TigerShark remains a solid, tank-like machine with a loyal following, and can make sense where a Hayward dealer relationship or an existing parts supply matters.
Where the TigerShark is strong
- Simplicity and toughness. The TigerShark's cartridge system is easy to service and the unit has a reputation for shrugging off years of use.
- Quick-clean cycle. Its shorter cycle option suits quick touch-ups.
- Hayward ecosystem. If your pool equipment is Hayward and your local dealer services it, keeping one brand can simplify support.
Where Dolphin pulls ahead
- Range depth. Dolphin offers cleaners for every pool and budget — above-ground (E10), value Wi-Fi (Nautilus CC Plus), premium (M700), cordless (Liberty 400) and full commercial lines.
- Navigation and coverage. CleverClean™ scanning maps the pool rather than bouncing randomly, which shows in fewer missed patches on odd-shaped pools.
- App control. MyDolphin™ Plus scheduling, cycle choice and remote steering on connected models — the TigerShark line has no equivalent.
- Filtration options. Interchangeable fine/ultra-fine media and top-load baskets on current models beat bottom-access servicing.
- Parts and service network. Dolphin's global service network (including the Middle East — see our worldwide guide) is broader for robotic cleaners specifically.
Energy and running costs
Both sip power compared with pressure or suction cleaners that need the main pump — see robotic vs pressure vs suction. Between the two, current Dolphins' shorter smart cycles generally finish the job in less runtime.
Bottom line
Buy the TigerShark if you're committed to Hayward and your dealer supports it. Otherwise, pick the Dolphin that matches your pool from our model list — start with the comparison guides if you're unsure which. Whichever brand you choose, the same maintenance habits decide how long it lasts.
