Dolphin Active 20 robotic pool cleaner for inground pools
Maytronics Inground Pool Robot

Dolphin Active 20 Robotic Pool Cleaner

The Dolphin Active 20 is a corded robotic pool cleaner designed for inground pools up to 50 feet. It scrubs the floor, climbs the walls, works along the waterline and filters common leaves, dirt and fine particles during an approximately two-hour cycle. Active brushing, CleverClean™ navigation, a top-load basket, interchangeable fine and ultra-fine filters, a weekly timer and an anti-tangle swivel cable make it a practical choice for homeowners who want broad pool coverage without connecting a cleaner to the pump, skimmer or plumbing.

Is This the Right Robotic Cleaner for Your Pool?

A cleaner can have strong specifications and still be the wrong match for a particular pool. Use this Dolphin Active 20 fit guide to decide whether the model covers the surfaces, debris and convenience features that matter most to you.

Best Suited For

  • Inground residential pools measuring up to approximately 50 feet in length.
  • Owners who want automatic floor, wall and waterline cleaning in one standard cycle.
  • Pools that collect a combination of leaves, insects, grit, pollen and fine sediment.
  • Buyers who value a top-access basket that can be removed and rinsed without turning the robot over.
  • Households that want scheduled cleaning every day, every other day or every third day.
  • People who prefer dependable corded performance instead of charging and storing a battery-powered unit.

Important Considerations

  • It does not include Wi-Fi, Bluetooth, app control or a handheld remote.
  • The standard cleaning duration is fixed at about two hours; enhanced selectable cycles are not included.
  • A caddy is generally an optional accessory rather than standard equipment with this model.
  • Steps, benches, tanning ledges and unusually tight corners may not receive the same coverage as open floors and walls.
  • Very heavy leaf loads may require emptying the basket more often or removing large debris manually first.
  • Wall-climbing performance can be reduced by slippery biofilm, poor water balance, a full filter or insufficient cable released into the pool.
Cleaning Performance

Key Features That Match Searcher Buying Intent

The most valuable Dolphin Active 20 features are not isolated specifications. They work together to determine coverage, debris pickup, handling and how much manual cleaning remains after the robot finishes.

Active scrubbing brush icon

Powerful Active Scrubbing

A fast-spinning active brush agitates stuck-on dirt and algae film rather than relying only on suction. This improves cleaning on the floor and supports better traction as the robot moves onto vertical surfaces.

CleverClean smart navigation icon

CleverClean™ Navigation

Built-in scanning technology calculates an efficient route through the pool. The objective is more systematic coverage than a cleaner that depends entirely on uncontrolled random movement.

Top-load filter basket icon

Top-Load Filter Basket

The basket lifts out from the top, opens for debris disposal and rinses with a garden hose. This design makes routine maintenance faster and reduces contact with collected material.

Lightweight robotic cleaner icon

Quick Water Release

Water drains as the unit is raised, helping reduce the effective lifting load. Always retrieve it with the handle rather than pulling the floating cable.

Energy-saving pool cleaner icon

Independent Filtration

The robot uses its own motor and filtration basket. It does not need a booster pump or suction line, and captured debris does not have to travel through the pool’s primary filter.

Plug and play operation icon

Plug-and-Play Setup

Place the power supply in a protected position, connect the cable, lower the cleaner into the water and start the cycle. No permanent plumbing modification is required.

Realistic Expectations

Floor, Wall and Waterline Cleaning Explained

The Dolphin Active 20 is officially specified for floor, wall and waterline coverage. Understanding what those terms mean helps prevent unrealistic expectations about stairs, shelves and unusual pool geometry.

1

Pool Floor

The tracked drive system moves across flat areas, slopes and the cove while the brush loosens debris and the internal pump draws material into the basket. Main drains, raised fittings and very sharp transitions can temporarily interrupt the route.

2

Walls

Suction flow, track grip and brush contact help the robot climb. Clean filters, balanced water and walls free of slippery biofilm support better vertical performance. The robot may not climb every wall on every pass.

3

Waterline

When the unit reaches the top, it scrubs the area where oils, sunscreen and residue commonly collect. Coverage can vary around curves, fittings and irregular edges, so occasional spot brushing may still be useful.

Debris Management

Fine and Ultra-Fine Filtration for Different Pool Conditions

Searchers frequently compare robotic cleaners by filtration because a robot can move well and still leave cloudy residue behind. The Dolphin Active 20 includes interchangeable filtration options so the basket can be adapted to the debris in the pool.

Use the Fine Filter For

  • Leaves, insects and larger visible debris
  • Routine maintenance after normal pool use
  • Faster water flow when the pool contains mixed debris
  • Initial cleanup before switching to a finer filtration pass

Use the Ultra-Fine Filter For

  • Fine dust, pollen and smaller suspended particles
  • Residual material after brushing or chemical treatment
  • Cleaner finishing passes after large debris is removed
  • Situations where standard mesh filtration leaves visible sediment
Setup and Scheduling

How to Start a Cleaning Cycle and Use the Weekly Timer

The power supply provides straightforward operation without an app. Correct Dolphin Active 20 cable placement and post-cycle care are important for reliable coverage and longer component life.

1

Position and Connect

Place the power supply on a dry, protected surface at the manufacturer-recommended distance from the water. Connect the floating cable securely and use a properly protected electrical outlet.

2

Release Enough Cable

Lower the robot into the pool, rotate it gently until trapped air escapes and allow it to settle. Uncoil enough cable for the unit to reach the farthest wall without leaving excessive cable in the water.

3

Run or Schedule

Start a standard two-hour cycle or select the weekly timer option on the power supply. Scheduling can repeat the cycle daily, every second day or every third day during the active timer period.

Helpful Ownership Guide

Common Performance Checks Before Requesting Service

Basic maintenance resolves many coverage and climbing complaints. Disconnect power before inspecting or cleaning the unit, and follow the manufacturer’s safety instructions.

Not Climbing Walls

Clean the basket, check the brush and tracks, remove slippery wall buildup, verify water chemistry and make sure enough cable is available. If performance remains weak, inspect the impeller area or request professional support.

Leaving Fine Dirt

Switch to the ultra-fine filter panels, confirm that all panels are seated correctly and rinse them thoroughly. Remove heavy leaves first so the finer media can focus on small particles.

Cable Twisting

Use the swivel, release only the cable needed for the pool and periodically stretch the cord in sunlight for a short period to relax stored twists. Never drag or retrieve the robot by the cable.

Stops or Moves Slowly

Turn off and disconnect the power supply, then check for hair, string, leaves or small objects around the intake, impeller, brushes and tracks. A packed filter can also reduce movement and climbing.

Misses Steps or Ledges

Robotic cleaners are optimized for primary floors and walls. Narrow steps, shallow shelves, sharp transitions and complex ledges may require occasional manual brushing or vacuuming.

Timer Does Not Repeat

Confirm that the desired interval was selected on the power supply and that power remains connected. Weekly scheduling is temporary and may need to be reactivated after the programmed period or a power interruption.

Buyer Questions

Dolphin Active 20 FAQs

What size pool is this cleaner designed for?

It is currently specified for inground residential pools up to approximately 50 feet long. Pool shape, wall transitions and obstacles can still affect coverage.

Does it clean the waterline?

Yes. Current Maytronics specifications list floor, wall and waterline coverage. Irregular edges, ledges and some curved areas may still need occasional manual attention.

How long does one cleaning cycle take?

The default cycle is approximately two hours. It does not provide the multiple enhanced cycle-duration choices found on some higher models.

Does it have Wi-Fi or mobile app control?

No. Scheduling and start controls are handled through the power supply. Buyers who require smartphone operation should compare compatible higher-specification models.

What filters are included?

The current product specification lists a fine filter kit and an additional ultra-fine filter kit, allowing the filtration setup to be adjusted for larger debris or smaller particles.

Does it have an anti-tangle swivel?

Yes. The floating cable includes a swivel intended to reduce tangling. Properly releasing and periodically straightening the cable remains important.

Can it clean steps and tanning ledges?

Coverage of narrow steps, benches and shallow ledges is not guaranteed. These areas can be difficult for many robotic cleaners because of depth, geometry and limited room to maneuver.

Does it connect to the pool pump or skimmer?

No. It is a self-contained electric robot with its own motor, pump and filter basket. It does not require a booster pump or suction-side connection.

Is a caddy included?

A caddy is generally treated as an optional accessory for this model. Confirm the exact package contents and any current promotion with Pool Place Easton.

What warranty is provided?

The manufacturer currently lists a two-year warranty. Coverage terms, exclusions, registration and service procedures should be confirmed at the time of purchase.
