The WaterGuru SENSE does is not compatible with swim spas, endless pools or infinity pools.
The WaterGuru SENSE is designed to fit in a pool's water skimmer. Swim spas, Endless pools and Infinity pools do not have skimmers.
The WaterGuru SENSE must be inserted in a water skimmer of either an above ground or in-ground pool. This protects the SENSE electronics that are underneath the WaterGuru cover from coming in contact with splashing water.
Note: Use of a WaterGuru SENSE is not supported for swim spas, endless pools or infinity pools. Such use would void the 1-year Warranty.
