Best Cordless Robotic Pool Cleaners (2026): Top 8 Compared
A cordless robotic pool cleaner is a battery-powered robot that vacuums and scrubs a pool without a power cable running to the deck. It is charged out of the water, or on a dock, and then runs a cleaning cycle on its own before parking at the wall or surface for retrieval. This page covers battery-powered models only. Where a brand also sells corded robots, its cordless model is the one listed. The eight products below fall into three groups. The Aiper Scuba X1, Dolphin LIBERTY 400, Dreame Z1, iGarden K Series and Seauto Crab clean the floor, walls and waterline. The Beatbot AquaSense 2 Pro adds water surface skimming. The WYBOT S2 Solar Vision adds a solar-powered underwater charging dock. Polaris documents its cordless FREEDOM in detail but publishes no US list price. Every comparison below uses the brands' published specifications and US list prices.

These comparisons draw on public product information, not hands-on testing of every tool. Source records identify available references and checks; missing evidence is marked. Buyer fit is an editorial assessment, not a measured performance score. How to use this research.
A cordless robotic pool cleaner does the routine work of vacuuming and scrubbing a pool on battery power, with no cable running across the deck. The owner charges it, drops it in, and collects it when it parks at the wall or surface. The robot collects debris in its own filter basket and does not rely on the pool’s pump.
The eight products compared here take different routes to that job. The Aiper Scuba X1, Dolphin LIBERTY 400, Dreame Z1, iGarden K Series and Seauto Crab clean the floor, walls and waterline, and charge on a dock, magnetic connector or cable. The Beatbot AquaSense 2 Pro also cleans the water surface. The WYBOT S2 Solar Vision recharges on a solar-powered dock. Polaris publishes specifications for the FREEDOM but no US price.
Every entry was checked against the brand’s own US store, product page or manual in September 2026. Seven publish a US list price, from $429 to $2,299. Polaris does not. Prices are regular list prices, not promotions.
Vendor details and trade-offs
The Aiper Scuba X1 is the mid-line model in Aiper's in-ground Scuba range, sold in the United States through Aiper's own online store. The published specification sheet rates the X1 for concrete, fibreglass, vinyl and tile pools of up to 2,150 square feet or 66 feet in length. It cleans the floor, walls and waterline.
Aiper lists a 6,600 gallons-per-hour pump, four motors, 14 sensors and dual active rollers at the front and rear. Its WavePath 3.0 navigation offers different routes for different pool shapes, and Aiper describes an adaptive path for bowl-shaped or irregular floors. Ultrasonic sensors are used to detect obstacles.
Filtration uses a 5 L top-load basket with two filters. The standard filter handles leaves and sand, and the MicroMesh ultra-fine filter is rated by Aiper for particles down to about 3 microns. Aiper recommends rinsing both after each use.
The battery is rated for up to 180 minutes, with a four-hour charge. The box includes a charging dock, a DC charger and a retrieval hook, and the robot weighs 24.25 lb. The Aiper app shows status, and the X1 receives over-the-air updates.
Potential strengths
- Largest filter basket among the eight, at 5 L
- Charging dock and DC charger both included

The Beatbot AquaSense 2 Pro is a cordless robot that Beatbot sells as a five-in-one cleaner. The five functions are surface, waterline, floor and wall cleaning plus water clarification. Beatbot rates it for pools of any common shape with up to 3,875 square feet of floor.
Navigation runs on a four-core processor and 22 sensors, two of them ultrasonic, and Beatbot uses the names CleverNav and SonicSense for the path planning and mapping. The company notes that mapping may fail in pools with strongly curved floors and walls. The pump is rated at 5,500 gallons per hour, and the robot has nine motors.
The 13,400 mAh battery takes about 4.5 hours to charge on the included dock. Beatbot's product page quotes up to 5 hours of floor cleaning, up to 5 hours of wall and waterline cleaning, and up to 11 hours of surface cleaning. After a cycle or when the battery is low, the robot parks at the surface and sends an app alert. The app can steer the robot only while it is at the surface.
The filter basket holds 3.7 L and uses two layers of 150 and 250 microns. The ClearWater system releases a clarifying agent that Beatbot says is made from crab shells, and the agent is bought separately. Beatbot gives a working depth of 0.5 to 3 m and a robot weight of 25.08 lb.
Potential strengths
- Covers the water surface as well as floor, walls and waterline
- Three-year warranty that Beatbot describes as full replacement
Trade-offs
- Highest list price among the priced entries
- Heaviest published robot weight here, at 25.08 lb

The WYBOT S2 Solar Vision is a cordless robot built around a solar-powered charging dock. When the battery falls below 20%, the robot returns to the dock on its own to recharge. It can also be charged from the supplied DC adapter, which WYBOT's manual rates at about three hours for a full charge.
The manual rates the S2 Solar Vision for pools up to 300 square metres, or 3,229 square feet, and 3 m (9.8 ft) deep. Runtime is 2.5 hours from a 5,200 mAh battery, and the flow rate is 3,962 gallons per hour. The robot weighs 8.5 kg (about 18.7 lb). The solar panel and station together weigh 12.5 kg. The manual also asks that the dock be installed where the water is at least 1.2 m deep.
WYBOT says the robot cleans the floor, walls, waterline, slopes and steps. Its AI Vision mode uses a camera to find debris, and WYBOT states that this mode works on the floor only. Weekly schedules can start the robot automatically. Filtration combines a 180-micron filter box with an ultra-fine sponge.
WYBOT's FAQ advises charging with the adapter for heavily soiled pools, since the solar dock may not supply enough energy for frequent cleaning. It also advises spacing scheduled cleans further apart where the dock gets limited sun.
Potential strengths
- Can recharge from solar power without the owner lifting the robot out
- Documented for slopes and steps as well as floor, walls and waterline
Trade-offs
- AI Vision mode covers the floor only, and solar charging depends on sun at the dock
- The solar panel and dock add 12.5 kg and need a suitable installation spot

The Dolphin LIBERTY 400 is one of Maytronics' cordless LIBERTY models for residential pools. In the United States it is sold through the Maytronics online store as a store exclusive.
Maytronics rates the LIBERTY 400 for pools up to 33 feet long. It cleans the floor, walls, waterline and sun ledge, and the product page describes cleaning at an 11 ft depth. Listed surfaces are liner, gunite and fibreglass, in rectangular, round, kidney and free-form pools, above or in the ground. The default cycle is 2.5 hours, and an Eco mode splits a single charge into shorter cycles across the week.
Charging uses Magnetic-Connect, which Maytronics describes as inductive charging. Filtration uses a top-access combined filter kit, and an ultra-fine filter kit comes in the box. An active brush scrubs the surfaces.
Click-Up is a sound-activated feature that brings the robot up to the owner for removal. The MyDolphin Plus app connects when the robot is out of the water. The robot weighs 17.861 lb, and Maytronics lists a three-year warranty. The store comparison table also shows the LIBERTY 600 at $1,729 and the LIBERTY 300 at $1,249 for buyers weighing other sizes.
Potential strengths
- Three-year warranty

The Dreame Z1 is the base model in Dreame's cordless pool robot range, below the Z1 Pro. Dreame sells it in the United States through its yard care online store.
Dreame rates the Z1 for up to 1,950 square feet of pool, cleaning the floor, walls and waterline. It lists a maximum suction of 8,000 gallons per hour and describes horizontal cleaning along the waterline. Navigation fuses ultrasound and 3D structured light to find boundaries. The Z1 detects the pool's shape and divides it into zones cleaned in S-shaped paths.
Four modes are offered: a global mode that cleans the floor and then the walls and waterline, plus floor-only, wall-only and waterline-only modes. They can be selected on the robot or in the Dreamehome app, but the app does not work while the robot is underwater. After cleaning, the robot parks at the pool edge for pickup.
Dreame quotes over 180 minutes of working time, with a footnote that the figure comes from its own lab test of floor cleaning in ECO mode. Charging uses a magnetic charger and takes four to six hours. Dreame states the Z1 is suitable for saltwater pools up to 5,000 ppm salt and 4 ppm chlorine.
Potential strengths
- Highest rated pump flow among the eight, at 8,000 GPH
- Four modes selectable on the robot or in the app
Trade-offs
- Rated coverage of 1,950 sq ft is below the Aiper, Beatbot, WYBOT and Seauto ratings

The Polaris FREEDOM is the cordless robotic cleaner from Polaris, whose US product support is handled through Fluidra. The US product page gives specifications but no price, and the owner's manual directs warranty service to the original dealer.
Polaris says the FREEDOM cleans the floor, walls and waterline in 2.5 hours or less. Two modes, floor only and floor plus walls and waterline, are chosen on the robot. The iAquaLink app adds a waterline-only mode and SMART Cycle, which works out a cleaning time for the pool. The app also shows charging status and sends a notice when a cycle ends. Polaris lists no scheduling.
The owner's manual rates the robot for in-ground pools 15 inches to 13 feet deep, with water between 55 and 95°F. The robot weighs 20 lb and uses a 9.6 Ah battery. A double helix brush pushes debris toward the inlet, and a 4 L canister with a transparent lid holds it.
The robot charges in under five hours on the Easy-Charge Station by direct contact. The manual asks for a GFCI outlet at least 11.5 feet from the pool, with no extension cord, out of direct sun and rain. At the end of a cycle the robot climbs to the waterline for pickup. Tapping it with a pool pole also makes it climb to the waterline, which Polaris calls Tap & Lift.
Potential strengths
- Deep operating range of 15 in to 13 ft
- 4 L filter canister with a transparent lid
Trade-offs
- No published US price
- No scheduling, and the charging station must stay out of sun and rain

Frequently asked questions
What is a cordless robotic pool cleaner?
It is a battery-powered pool robot that runs without a power cable to the deck. It charges out of the water or on a dock, then vacuums and scrubs the floor and, on most models, the walls and waterline before parking for retrieval. It filters debris into its own basket instead of using the pool's pump. Corded robots draw power through a floating cable and are not covered on this page.
How much do cordless robotic pool cleaners cost?
US list prices on the brands' own stores range from $429 for the Seauto Crab to $2,299 for the Beatbot AquaSense 2 Pro. In between are the iGarden K Series at $799 to $1,399, the Dreame Z1 at $1,299, the Dolphin LIBERTY 400 at $1,429, the Aiper Scuba X1 at $1,499.99 and the WYBOT S2 Solar Vision at $1,999.99. Several stores showed lower promotional prices in September 2026. Polaris publishes no US price.
How long does a cordless pool robot run on one charge?
Published figures range from 2 to 3 hours for the Seauto Crab and 2.5 hours for the WYBOT S2 Solar Vision and Dolphin LIBERTY 400 default cycle. The Aiper Scuba X1 is rated for up to 180 minutes. Beatbot quotes up to 5 hours of floor cleaning for the AquaSense 2 Pro, and the iGarden K90 is rated for 4.75 hours of full coverage. Dreame's figure of over 180 minutes comes from its own ECO-mode floor test.
Which cordless robots clean the water surface?
Among the eight, only the Beatbot AquaSense 2 Pro is documented for cleaning the water surface. Beatbot rates it for up to 11 hours of surface cleaning, and its app can steer the robot while it is at the surface. The other seven are documented for the floor, walls and waterline. Aiper and iGarden state that their robots scrub about 2 inches above the waterline.
How do the charging methods differ?
Aiper and Beatbot supply charging docks, Maytronics uses Magnetic-Connect inductive charging, and Dreame uses a magnetic charger. Seauto and iGarden supply chargers. WYBOT's S2 Solar Vision can recharge on a solar-powered dock that it returns to by itself, or from a DC adapter. Polaris uses a direct-contact charging station, which its manual says needs a GFCI outlet at least 11.5 ft from the pool.
Which models suit above-ground pools?
Maytronics lists the Dolphin LIBERTY 400 for in-ground and above-ground pools, and iGarden lists the K Series for both. Beatbot's FAQ states its pool robots can be used in above-ground pools. Aiper rates the Scuba X1 for in-ground pools and sells separate above-ground models. Seauto rates the Crab, and Polaris the FREEDOM, for in-ground pools. Buyers should also check the minimum depth each brand states.
Does the FCC's 2026 robot rule affect cordless pool cleaners?
On July 28, 2026, the FCC added foreign-produced advanced robotic devices to its Covered List. Its FAQ states that pool robots able to work both underwater and at the surface are not excluded as underwater vehicles. Covered devices cannot get new FCC authorization, but the FCC says already authorized models can still be imported and sold, and owners can keep using their devices. The FAQ does not name specific models.
How was this list put together?
This page is a research comparison of published specifications and US list prices, checked on each brand's own US store, product page or manual in September 2026. No product was tested hands-on. Only battery-powered models are included. Where a store showed a promotion, the regular list price is quoted. Position on the page is not a ranking, and no brand has confirmed its entry.
