Robot pool cleaners that clean the waterline
The waterline is where oils and sunscreen build up a scum ring that floor-only robots leave behind. Every robot here lists waterline cleaning in its coverage or use cases. Coverage claims come from each maker, so confirm it on the listing for your pool shape and tile type before you buy.
