Cleaning time varies by model and settings, but there is a clear normal range — and you never have to babysit it.
Typical Cycle Times
Most robots offer cycles in this range:
- Quick / floor-only: roughly 1 to 1.5 hours
- Standard floor and wall: about 2 hours
- Full clean with waterline: 2.5 to 3 hours
Premium models let you choose the mode to match the job, and a weekly timer can run these automatically.
What Changes the Time
Cycle length is driven by pool size, the selected mode, and how dirty the pool is — heavier debris and larger pools take longer. Smart, gyroscopic robots often clean more thoroughly in less time because they map an efficient route instead of bouncing randomly and repeating areas, which is also why they avoid missing spots.
You Can Leave It Running
There is no need to watch the robot; just do not swim while it runs, and remove it when the cycle ends. For efficient, well-timed cleaning, a model like the Dolphin Sigma is hard to beat — compare cycle features in our best robotic pool cleaners guide.
