OWNERSHIP

Living with it.

Stable pressure-side mechanism with minimal electronics; cable swivel is the primary wear point.

Owner reports describe consistent performance across 5+ years. No major firmware issues (no smart controls). Cable swivel replacement documented every 3–5 years; brush cartridge every 2–3 seasons. Corrosion risk in salt systems.

Common questions

What people actually ask.

5 answered
OperationDoes the Dolphin S200 work with above-ground pools?
No. Pressure-side cleaners require a pool pump with a dedicated return line; above-ground pools typically use simpler circulation systems. A different cleaner type (suction or cordless) would be required.
OwnershipHow often do I need to replace the brush cartridge?
Owner reports indicate brush replacement every 2–3 seasons (roughly 2–3 years) depending on pool chemistry and debris load. Individual brushes cost approximately $40–60 per replacement.
OperationCan the S200 handle heavy leaf load in fall?
Moderate leaf load yes; heavy fall debris benefits from pre-skimming. Large leaves can jam the intake; a pool skimmer should be run before the robot to avoid weekly clogs.
OwnershipWhat is the cable swivel, and does it need maintenance?
The cable swivel prevents the hose from twisting as the robot moves. Owner reports recommend rinsing it weekly and replacing it every 3–5 years as the mechanism wears (~$80 replacement part).
OperationDoes the S200 work in chlorine pools and salt-water systems?
Chlorine pools yes; salt-water systems are not recommended. Corrosion reports are documented on salt-water units, even with material upgrades. Manufacturer guidance specifies freshwater chlorine pools.
