01 Classification

What each one does on its own.

The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.

Any task, any setting

02 Assessment

Where they actually differ.

The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

03 Measured against the class

How far apart is a long way?

A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

Maytronics Dolphin Oasis Z5i

Dual tracks climb walls and deliver full waterline reach, but the system costs $1,500+ when a floor-only corded model runs $300-500.

Maytronics Dolphin Quantum

Scheduling is real but blind. The power supply’s built-in weekly timer will start a cycle every day, every other day or every third day without anyone present, but there is no app, no status and no way to know the filter is loaded until the next time the unit comes out of the pool.

Who each one is wrong for

Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.

Maytronics Dolphin Oasis Z5i
Pools longer than 50 ft or beyond the cord's reach
Maytronics rates the Z5i by pool shape and length, up to 50 ft, and the 60 ft cable has to reach an outlet serving the pool area. Surface material is not a constraint: Maytronics sells Dolphin cleaners across pool surfaces, vinyl included.
Renters or short-term pool owners
Purchase price and dealer setup make ownership economical only for 5+ year tenures. No major resale market for commercial-grade dealer units.
Owners who want cordless operation
The 60 ft cord ties the unit to a poolside outlet, and it is placed in the water and lifted back out by hand at each cycle. There is no cordless version of this model.
Maytronics Dolphin Quantum
Pools longer than 50 ft
Maytronics rates this SKU by pool length, up to 50 ft, and by shape (rectangular, round, free shape, kidney). It lists both in-ground and above-ground installation, so the installation type is not the constraint. Length and the 60 ft cable run are.
Small pools where the capability goes unused
Wall and waterline coverage and two filter kits are sized for mid-to-large residential pools. On a compact pool most of that capacity sits idle for the same purchase price.
Remote or cable-constrained pool locations without cable storage
Corded operation requires running cable from equipment room or storage location to pool. Cable management difficult in remote or open-design pools.
Owners who want app control or remote status
Maytronics lists no Wi-Fi, mobile app or remote control for this SKU. Scheduling is set on the power supply's built-in weekly timer, and there is no way to see or change a cycle from a phone.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

Maytronics Dolphin Oasis Z5i
  • After every cycle: Lift the filter out of the top-load housing, unsnap the bottom and rinse it with fresh water.
  • Monthly: Check the brushes and tracks for wrapped debris; inspect the cable for kinks.
  • Annually: Check the brushes and filter panels for wear and replace them when worn. Maytronics publishes no replacement interval or price for either.
  • Seasonally: For freezing climates, remove the unit from the pool and store it and the cable indoors, out of direct sun.
  • As needed: Swap between the fine and ultra-fine filter kits to match the debris the pool is carrying.
Maytronics Dolphin Quantum
  • After every cycle: Lift the filter kit out of the top-load housing and rinse it with a hose. A loaded filter costs suction directly.
  • Monthly: Inspect the cable and swivel for damage and check the brushes for wear.
  • Annually: Clean the motor intake and check the filter panels for tears. Both filter kits ship with the unit and are washable; Maytronics publishes no replacement interval or price for them.
  • Seasonally: Drain residual water from the unit, then store it and the cable indoors, out of direct sun.

Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
