## Verdict

The Quantum is a plain corded Dolphin for in-ground pools up to 50 ft that want strong waterline scrubbing and a big basket without an app. The Pool Nerd rated it 5/5 against the Beatbot AquaSense 2. Skip it if you want app control, or if $1,999 is too much for a robot with a 2 year warranty.

## Cons
