The Dolphin Liberty 200 scrubs an inground pool's floor, walls and waterline without a power cable in the water, and Dolphin gives its cleaning cycle as 2.5 hours. An active brush and top-access filter handle the cleaning work as it travels on tracks and follows patterned paths through the pool. The Amazon listing says it uses magnetic charging.
Who It's For
You have an inground or above-ground pool up to 33 feet long and want a cleaner that reaches the walls as well as the bottom. Rectangular, round and freeform layouts are compatible, including pools with curved outlines. It suits an owner who prefers a battery-powered cleaner and wants to avoid laying out and collecting a floating power cable for each session. If dirt collects along the waterline, the Liberty 200 includes that area in its cleaning coverage as well.
Look Elsewhere If
You may want a different robot if your pool is longer than its 33-foot rating. It also has no app connectivity for managing cleaning from your phone. A steeply sloping pool floor is another reason to choose differently. Its working incline is 15 degrees, so a sharper transition into the deep end falls outside its range. The manual also says not to run it after adding liquid flocculant or another clarifier, because these damage its filters.
Where To Buy
Key Features
Active Brushing And Coverage. Dolphin describes active scrubbing across the pool surface, with cleaning coverage extending from the bottom to the walls and waterline. The powered brush is useful when you want the cleaner to scrub surfaces as it collects debris. If your usual cleaning involves brushing the walls separately from vacuuming the floor, its coverage could reduce some of that manual work. Dolphin identifies the brush as a Standard Brush in its specifications and confirms that it scrubs the waterline.
Navigation And Tracks. Dolphin calls its navigation CleverClean, and the Liberty 200 follows patterned paths through the pool. It travels on tracks during floor cleaning and wall climbing. Its compatibility also covers freeform layouts, so the route does not require a rectangular pool outline. The manual describes using the supplied grab hook on a pool pole to bring the robot to the waterline. You then lift it out by hand.
Filtration And Access. The filter is reached through the top of the body, so access does not require turning the cleaner over. Suction is rated at 4,000 gph, with compatibility covering fine, medium and large debris.
Battery And Charging. The cleaning cycle lasts 2.5 hours, according to Dolphin. Charging is a separate part of using the cleaner because the manual says to charge it out of the water in a shaded spot. The Amazon listing describes magnetic charging. For an owner replacing a corded cleaner, the practical change is handling the robot for recharging instead of laying out and collecting a power cable around the pool.
Surfaces And Finishes. Compatibility includes vinyl, gunite, fiberglass and tile, along with pebble and exotic finishes. Hard and soft walls are also covered. Water treatment compatibility includes saltwater, chlorine and mineral water. You can also use it in a pool treated with ozone or ultraviolet systems.

How It Compares
Dolphin Explorer E50 Check Price on Amazon
Dolphin Explorer E50 adds app scheduling and a corded power supply for an owner who wants recurring cleans in a pool up to 50 feet long, with more length capacity than the Liberty 200. Choose it if you want to avoid battery charging between sessions and are comfortable handling a power cable when you put the cleaner in and take it out.
Dolphin Proteus DX4 Check Price on Amazon
Dolphin Proteus DX4 offers onboard scheduling for an owner who wants repeat cleaning times set on the equipment and needs coverage for a pool up to 50 feet long. Its corded setup uses a 60-foot cable and runs a cleaning cycle of 2 hours, so it suits someone who accepts cable handling in exchange for scheduled starts without charging a battery between sessions.
Aiper Scuba S1 Pro Check Renewed Price on Amazon
Aiper Scuba S1 Pro keeps cordless operation while adding app scheduling and support for pools up to 66 feet long, so it suits an owner who needs more reach and control over cleaning times. Its runtime reaches 3 hours, although its 20.9-pound body is heavier to carry than the Liberty 200 when you lift it out after a clean.
Worth Knowing
Dolphin's product page also includes sun ledges in the cleaning coverage. That could be useful if debris regularly settles on a shallow shelf as well as on the main floor, particularly where you otherwise need to clean that shelf separately.
The warranty lasts 2 years. The robot weighs 17.9 pounds. Dolphin calls the filter arrangement a Combine Filter Kit and describes the top-load basket as fine filtration. Its product page also offers replacement fine-debris baskets as add-on accessories. A user manual is linked from the support section of Dolphin's product page for this cleaner.
Care And Maintenance
From the Dolphin manual:
- Quick-rinse the filter immediately after lifting the robot out, so debris does not harden.
- Open the filter cover, lift out the basket and release its bottom lid to empty debris. Hose the filters clean inside and out.
- Recharge the robot in a shaded, protected spot until the battery indicator shows a full charge.
- Wash the filter panels about once a month, following the manual. To clean the impeller, connect the charger to switch the robot off, then insert the impeller safety tool.
- Charge the battery to about half before off-season storage. Store the robot away from heat and charge it fully before using it again.
Frequently Asked Questions
How large a pool can it clean?
Up to 33 feet long. Rectangular, round and freeform layouts are included, so a curved outline is compatible too.

Yes, within the manual's water limits. Saltwater is within its compatibility, alongside chlorine and mineral water, and it also supports pools using ozone or ultraviolet treatment.
How heavy is it to carry?
17.9 pounds. You will handle that weight when you remove the cleaner from the water and carry it to its storage location.
How do I reach the filter?
Through the top of the cleaner. Dolphin describes the top-load basket as fine filtration.
Can it collect fine debris?
