Corded Robots That Scrub the Waterline for Under $1,500

The waterline is where oils, sunscreen and pollen collect into the grey ring every pool gets, and it is the one surface the pump and skimmer never touch. Corded robots still have one real advantage over battery ones for this job: they never run out halfway through a waterline pass. Under $1,000 only one corded robot in this catalog scrubs the waterline at all, so this list stops at $1,500, where the choice widens to both of the big pool-trade brands.

How this list is ordered: Corded robots whose maker lists waterline scrubbing, priced under $1,500, ordered by price. 7 of the catalog’s robots qualify.
