The Dolphin Quantum is one of Maytronics’ most advanced residential robotic pool cleaners, positioned between their mid-range and ultra-premium lines. It’s known for its massive filter capacity, advanced navigation, and extra scrubbing power—making it a favorite among pool owners who want a serious cleaning machine without going to the top price tier.
We tested the Dolphin Quantum extensively in a medium-to-large in-ground pool to evaluate its cleaning performance, ease of use, and value compared to other models in the Dolphin lineup.
First Impressions
Right away, the Quantum looks built for business. Its bold white-and-blue design, wide cleaning path, and thick rubber tracks give it a rugged, professional feel. The unit comes with a 60-foot tangle-free swivel cable, a massive top-loading filter basket, and a lightweight power supply. There’s no app control here—everything is managed from the power unit, which keeps things simple and reliable.
Key Features
- Coverage: Cleans floors, walls, and waterline.
- Navigation: SmartNav 2.0 pool scanning for efficient coverage.
- Filtration: Extra-large top-loading basket with fine and ultra-fine filters.
- Brushes: Dual HyperBrush™ active scrubbing brushes.
- Cable: 60-foot swivel cable for tangle prevention.
- Cycle Time: 2 hours for a standard clean.
- Energy Use: Low-voltage operation for high efficiency.
Performance Testing
We ran the Quantum in a 20’ x 40’ in-ground pool for multiple weeks under different debris conditions, from normal daily dirt to heavy post-storm cleanup.
Floor Cleaning
The Quantum’s strong suction and HyperBrush system worked wonders on fine dirt, sand, and leaves. The dual brushes loosened stubborn debris before the vacuum intake pulled it into the basket. Even with large debris loads, suction remained strong thanks to the huge filter capacity.
Wall and Waterline Cleaning
Wall climbing was smooth and consistent, and the Quantum’s scrubbing at the waterline was notably aggressive compared to many competitors. This helped remove built-up oils and dirt without manual brushing.
Navigation
SmartNav 2.0 guided the Quantum in an organized pattern, minimizing wasted passes. It easily navigated around ladders, steps, and benches without getting stuck, and coverage was near-complete on every cycle.
Debris Handling
The oversized filter basket is one of the Quantum’s biggest advantages. It holds significantly more debris than standard baskets, meaning less frequent emptying. The dual-layer system allows you to use fine or ultra-fine filters depending on the cleaning needs.
Ease of Maintenance
Maintenance is straightforward—pop the basket out from the top, dump debris, rinse, and reinstall. The rigid design makes handling easy, and the top-loading system means no flipping the robot upside down.
Energy Efficiency
Like all Dolphin robots, the Quantum operates on low voltage and uses a fraction of the energy of suction or pressure-side cleaners. The standard 2-hour cycle is usually all that’s needed, further saving power.
Durability Over Time
During testing, the Quantum held up extremely well. The tracks maintained strong traction, the brushes showed minimal wear, and the cable swivel prevented major tangles. Proper storage should keep it running for many seasons.
