Identify the exact finish
Generic advice for a new pool is not enough. Traditional plaster, exposed aggregate, fiberglass, vinyl, and applied coatings cure or settle differently. Ask the builder to name the product and provide its startup guide, not only a verbal waiting period.
Protect the warranty trail
Finish warranties may depend on startup chemistry, brushing, and equipment restrictions. Save the builder's instructions and any manufacturer response about robot use. If advice conflicts, pause and have the responsible parties resolve it in writing before placing the cleaner in the pool.
Expect startup dust
Some finishes release substantial dust during startup. A robot filter can load quickly, reduce flow, and drag concentrated grit if used prematurely. Manual brushing toward the main drain and attention to the primary filter may be part of the prescribed process.
Inspect fittings and transitions
New drains, returns, lights, steps, and wall-floor transitions should be complete, secure, and free of construction debris. Nails, grout fragments, sharp plastic, or loose material can damage both the finish and robot. Remove hazardous items manually.
Introduce the robot gradually
When approved, begin with a normal supervised cycle using the correct brush and mode. Inspect the finish, tracks, brushes, and filter afterward. Stop if you see marking, unusual residue, embedded grit, or repeated rubbing at a construction detail.

Frequently asked questions
How soon can a robot enter new plaster?
There is no universal date; follow the finish installer's startup plan and the robot manufacturer's instructions.
Can a robot replace startup brushing?
Not unless the finish provider explicitly says so. Manual brushing is often a defined part of startup.
What records should I keep?
Keep the finish name, startup guide, chemistry log, approval messages, and date of the first robot cycle.
Final decision
Match the answer above to the exact model manual, pool measurements and maintenance routine. Amazon listings can change by seller, bundle and generation, so verify the product name and ASIN before relying on a feature.
