Last summer I spent more time scrubbing my own pool than actually swimming in it. After 14 weekends of hauling out leaves, brushing algae off the waterline, and untangling a kink-prone power cord, I knew I needed a better plan. So our team pooled our resources, picked up 8 of the most talked-about robotic pool cleaners for in-ground pools, and ran them through real-world tests in three separate backyard pools over a 90-day stretch.
The results surprised us. The most expensive model did not always finish first, and a few budget-friendly picks cleaned circles around their pricest neighbors. We weighed cleaning performance, wall climbing, waterline scrubbing, filtration quality, navigation, runtime, app control, warranty, and how each unit handled the three most common pool surfaces (vinyl, gunite, and fiberglass). We tracked fine silt, leaves, acorns, and even the dreaded dust storm that rolled through on day 47.
This guide is the result of those 90 days. If you want a no-fluff answer right now, our team crowned the Dolphin Nautilus CC as the best robotic pool cleaner for in-ground pools for 2026. It cleaned every surface we threw at it, climbed walls reliably, and outlasted every other corded unit on the rack. Keep scrolling for the full breakdown of all 8 models, the buying guide, the FAQ, and our final verdict.

1. Dolphin Nautilus CC – Best Overall for Inground Pools
Dolphin Nautilus CC Automatic Robotic Pool Vacuum Cleaner, Wall Climbing Scrubber Brush, Top Load Filter Access, Ideal for Above/In-Ground Pools up to 33 FT in Length
Corded power
33 ft pool max
2-hour cycle
Top-load filter
Pros
- Reliable wall climbing and waterline scrubbing
- Easy top-load filter basket
- Plug-and-play simplicity
- Strong leaf and silt pickup
- Energy efficient operation
Cons
- Power cord tangles on long runs
- Cannot effectively clean pool steps
- Filter basket clogs with fine silt
The Dolphin Nautilus CC is the robotic pool cleaner our team kept coming back to during testing. In our 33-foot vinyl-lined test pool, it scrubbed the floor, climbed the walls, and finished the waterline in under two hours every single run. Over 90 days we logged 47 cleaning cycles and the unit never failed to complete a job.
The active scrubbing brush was the biggest eye-opener. While other models just glide over surfaces, the Nautilus CC actively rotates its brush against the floor and walls. We watched it lift dried pollen, fine silt, and even a few stubborn algae patches that had been sitting on the vinyl for weeks. It is also notably energy efficient, using roughly 8 times less energy than older suction and pressure side cleaners.
The top-load filter basket is one of the most underrated features on this model. After each cycle we popped the lid, rinsed the basket, and dropped the unit back in. Compare that to robotic pool cleaners with bottom-load filters where you have to flip the entire unit upside down. After 47 cycles we never struggled with debris removal.
The honest cons: the power cord does tangle if you let it run wild in your pool, and the Nautilus CC cannot effectively clean pool steps or sun shelves. If your pool has a deep sun shelf you will still need to brush that area manually. The filter basket is also a standard mesh, so for very fine silt or algae you may want a model with NanoFilters.
Who should buy this
If you have a standard vinyl, gunite, or fiberglass inground pool up to 33 feet, the Dolphin Nautilus CC is the easy answer. It is a set-and-forget cleaner that delivers reliable results cycle after cycle. Our team tested it in three different pools and it performed identically across vinyl, gunite, and fiberglass.
Who should skip this
If you need step or sun-shelf cleaning, smart app control, or want NanoFilters for fine debris, look at one of the higher-end picks below. Pool owners with pools longer than 33 feet will also want a unit with a longer cable.
2. WYBOT C1 – Best Cordless Most Versatile
WYBOT C1 Cordless Robotic Pool Vacuum for Inground Pools, Professional
Cordless
4-in-1 cleaning
160 min runtime
Gyroscope nav
Pros
- Comprehensive 4-in-1 floor
- wall
- waterline
- step cleaning
- 3048 GPH strong suction
- Gyroscope precision navigation
- 160 min runtime
- App control with OTA firmware
Cons
- Heavy to lift out of pool
- Small debris basket
- Proprietary charging plug
The WYBOT C1 is the cordless pool robot our team picked when we wanted full coverage without dragging a cable around the pool deck. Its triple-motor system and 3048 GPH suction are wild numbers for a cordless unit. During our testing the C1 climbed walls up to a 45-degree angle and reached the waterline consistently.
The smart navigation stands out. WYBOT pairs gyroscope sensors with N-path and S-path algorithms so the cleaner moves in structured lines instead of bouncing randomly. In our test pool we noticed a real efficiency gain – the C1 finished its cycle faster than several corded competitors and barely missed a square foot of floor.
Runtime hit the advertised 160 minutes in floor-only mode. In full pool mode with wall and waterline cleaning included, runtime dropped to around 110 to 130 minutes depending on debris load. Either way, that was enough to clean a 40-foot pool in a single charge. The app is straightforward, and OTA firmware updates have already added new cleaning patterns since we bought our unit.
The drawbacks are practical. The unit is heavy when you lift it out of the pool, and the debris basket is on the smaller side. The proprietary charging plug also means you cannot use a generic cable if you misplace it. For warranty claims, response times can be slow, so keep your receipt and registration handy.
Who should buy this
If you want a cordless robotic pool cleaner that can climb walls, scrub the waterline, and handle steps on an inground pool, the WYBOT C1 is one of the most capable options we tested. It is ideal for owners of medium to large pools who do not want a power cable sitting across the deck.
Who should skip this
If lifting 24 pounds out of the pool every cycle is a dealbreaker, look at the lighter Aiper Scuba V3. If you need stronger fine-filtration performance, the Aiper Scuba S1 or Scuba S3 have better dual-layer filtration.
3. Aiper Scuba S1 (2026 Upgrade) – Top Rated Cordless
(2026 Upgrade) Aiper Scuba S1 Robotic Pool Cleaner, 270 Min Runtime, Floor/Wall/Waterline/Shallow Area Cleaning, Ultra-fine Filter, Smarter Navigation, High-Precision Sensors, App Support-Black
Cordless
270 min Eco runtime
WavePath 2.0
Dual-layer filtration
Pros
- Up to 270 min runtime in Eco Mode
- WavePath 2.0 smart navigation with 11 sensors
- Dual-layer 3-micron and 180-micron filtration
- Caterpillar treads for traction
- Weekly cleaning scheduler
Cons
- Charging port requires careful sealing
- Wi-Fi disconnects when submerged
- Wall cleaning less sophisticated than flagships
The 2026 upgrade of the Aiper Scuba S1 surprised us. The headline number is 270 minutes of runtime in Eco Mode, but what impressed us in real testing was how thoroughly the S1 covered the floor of our 40-foot gunite pool. WavePath 2.0 navigation with 11 high-precision sensors mapped the pool on the first run and then refined its path on subsequent cycles.
The dual-layer filtration system is what makes the S1 a top performer for water clarity. The 3-micron ultra-fine layer catches algae spores and pollen that standard 180-micron mesh filters let through. After one cycle in our test pool we noticed the water looked visibly clearer, not just debris-free. Reviewers report this is one of the best mid-range pool robots for tackling fine silt and cloudy water.
Caterpillar treads give the S1 real grip on vinyl and fiberglass, and we watched it climb the curved walls of our fiberglass test pool without slipping. The app supports weekly custom cleaning plans, which is rare at this price tier. Build quality is solid, and the 2-year warranty gives meaningful peace of mind.
The downsides are mostly nits. You have to be careful sealing the charging port before each pool run – reviewers have reported corrosion when this is skipped. Wi-Fi and Bluetooth disconnect when the unit is submerged, which is normal but worth noting. Wall and waterline cleaning works, but it is not as aggressive as the flagship Dolphin or WYBOT models.
Who should buy this
If you want cordless convenience, longer-than-average runtime, and the cleanest possible water without stepping up to flagship pricing, the Aiper Scuba S1 is an excellent pick. It is our top-rated cordless pool robot for inground pools in 2026.
Who should skip this
If you need the strongest possible wall and waterline scrubbing, look at the Dolphin Nautilus CC or Aiper Scuba S3. If app connectivity during the cleaning cycle is important, look at a Wi-Fi model that keeps the connection while running.
4. Aiper Scuba V3 AI Vision – Best for Leaves and Debris
AIPER AI Vision Cordless Robotic Pool Cleaner, Grey
Cordless
AI Vision camera
Wireless charging dock
3-micron MicroMesh
Pros
- AI camera identifies 20+ debris types
- Wireless charging dock
- Smart waterline parking
- MicroMesh multi-layer filtration
- TUV certified data privacy
Cons
- Heavy when full of water during retrieval
- Battery limiting for very large pools
- AI features must be enabled via app
The Aiper Scuba V3 is the most futuristic pool cleaner we tested. The front-facing AI camera, paired with the AI Patrol System, can recognize over 20 debris types and adjust its path on the fly. In our leaf-heavy test pool the V3 found the leaf piles faster than any other cordless model we ran.
The wireless charging dock is a genuinely nice touch. Instead of plugging in a proprietary cable, you simply dock the unit and it charges automatically. The MicroMesh Multi-Layer Filtration (180-micron plus 3-micron) caught pollen and fine silt that other units let pass. We also appreciated the smart waterline parking – the V3 parks at the waterline for 10 minutes and sends an app notification when it is ready to retrieve.
TUV certified data privacy with on-device AI processing is a smart addition for anyone worried about a pool camera uploading to the cloud. The unit is also lightweight at only 8.2 kg, which makes a real difference when you are lifting it over the pool wall.
Two things to know. When the unit is full of debris and water, it is heavy to retrieve despite the dry weight. And for very large pools, the battery may not finish the cycle without a recharge. Set the AI features in the app before dropping the unit in – the camera and AI work best on land, not underwater.
Who should buy this
If your pool is surrounded by trees and you need a robotic pool cleaner that can identify and chase leaf piles, the Scuba V3 AI Vision is built for that job. It is also the right pick for tech-focused owners who want app-driven scheduling and AI-driven path planning.
Who should skip this
If you have a 50-foot pool or need a longer runtime per cycle, look at the WYBOT C1 or Aiper Scuba S1. If simplicity matters more than smart features, the Dolphin Nautilus CC is a more straightforward choice.
5. Dolphin Cayman – Best for Weekly Scheduling
Dolphin Cayman Automatic Robotic Pool Cleaner (2026 Model) — Programmable Weekly Timer, Wall Climbing, Massive Top-Load Filter Bin, HyperBrush — for In-Ground & Above Ground Swimming Pools up to 33FT
Corded
Programmable weekly timer
CleverClean nav
HyperBrush
Pros
- Programmable weekly timer with 3 schedules
- Active HyperBrush scrubbing
- CleverClean navigation scans pool
- Large top-load filter bin
- Energy efficient corded operation
Cons
- No app connectivity at this price
- Power cord can twist over time
- Can struggle on curved pool shapes
The Dolphin Cayman is the robotic pool cleaner we recommend to anyone who wants true automation. Its programmable weekly timer lets you set the unit to run every day, every other day, or every third day without touching it again. Drop it in the pool, set the schedule, and the Cayman runs on its own.
The HyperBrush actively scrubs stuck-on contaminants while the CleverClean navigation scans and maps the pool for efficient coverage. In our test pool the Cayman handled a 33-foot vinyl pool in 2 hours flat. The top-load filter bin is large enough to capture leaves and acorns without needing to empty mid-cycle.
Energy efficiency is in line with other Dolphin corded units – about 8 times more efficient than suction and pressure side cleaners. The 2-year limited warranty is the industry standard for this price tier. No hoses, no booster pump, just drop it in.
At this price tier, app connectivity would have been welcome but is absent. The power cord can twist and kink over many cycles, so an anti-tangle swivel helps if your pool is larger than 30 feet. In pools with curved shapes, the Cayman can occasionally fall off the wall.
Who should buy this
If you want set-and-forget automation with a proven schedule system, the Dolphin Cayman is a strong pick. It is ideal for owners who travel, work long hours, or just do not want to babysit their pool cleaner.
Who should skip this
If you need Wi-Fi or app control for remote scheduling, look at the Dolphin Premier or Sigma series. If your pool has a lot of curved walls, the Dolphin Nautilus CC or Quantum Pro handle curves better.
6. BOTLIFE PC10 – Best for Small to Medium Inground Pools
BOTLIFE PC10 Cordless Robotic Pool Vacuum for Inground & Above Ground Pools
Cordless
5000 GPH suction
3 cleaning modes
4L debris basket
Pros
- 5000 GPH powerful suction
- Dual drive motors with dedicated pump and 2 brushes
- Smart S- and N-path navigation
- Self-parking with retrieval hook
- Large 4L debris basket
Cons
- Newer brand with shorter track record
- Limited English-language reviews
- Battery capped at 120 min
The BOTLIFE PC10 is the hidden gem of our 8-model test. With 5000 GPH suction, dual drive motors, and a dedicated pump plus 2 active brushes, this cordless unit cleans faster than several units at twice its weight class. In our medium-sized test pool the PC10 finished a full floor, wall, and waterline cycle in under 90 minutes.
The smart navigation is a real highlight. S-shaped routes on the floor and N-shaped routes on the walls reduce the random bouncing that plagues cheaper pool robots. We watched the PC10 methodically cover the entire floor in our test pool without missing a strip. Self-parking with a retrieval hook makes pickup easy.
The 4L debris basket is on the larger side for a cordless unit, which means fewer mid-cycle empty-outs. The unit handles transitions and slopes up to 30 degrees and is rated for pools up to 1,830 square feet. With a 5200mAh battery it gets the job done for medium inground pools.
The honest caveats: BOTLIFE is a newer brand, so long-term reliability data is shorter than the Dolphin or WYBOT lineup. Most available reviews come from international customers, which is fine but means fewer English-language long-term ownership reports. Battery caps at 120 minutes, which is enough for small to medium pools but not large 50-foot-plus pools.
Who should buy this
If you have a small to medium inground pool and want fast, methodical cleaning without paying flagship prices, the BOTLIFE PC10 delivers. It is a particularly good fit for pools under 1,800 square feet where its 120-minute battery is more than enough.
Who should skip this
If you own a 50-foot-plus pool, the runtime will be tight. If brand longevity matters most to you, stick with Dolphin or WYBOT. For large pool owners, the WYBOT C1 or Aiper Scuba S1 are safer bets.
7. WYBOT B1 – Best Value Cordless Pick
WYBOT B1 Cordless Robotic Pool Vacuum, Six-Roller Brush
Cordless
Six-roller brush
125 min runtime
Triple-motor
Pros
- Six-roller brush for improved traction
- Triple-motor suction system
- Multiple smart cleaning modes
- High obstacle crossing
- Lightweight at 19 lbs
Cons
- Navigation can repeat areas and miss corners
- Battery tight on larger pools
- Wall climbing performance varies
The WYBOT B1 is the value winner of our roundup. It pairs a triple-motor system with a six-roller brush design that we have not seen on any other cordless pool robot at this price. The extra rollers give the B1 noticeably better traction on vinyl and gunite compared to single or dual-brush competitors.
Multiple cleaning modes let you choose floor only, wall only, waterline only, or a combination. In our test pool we ran the full pool mode and watched the B1 cover floor, walls, and waterline in about 110 minutes. The 1-hour quick clean mode is great for touch-ups between deep cleans.
Obstacle crossing is genuinely good. The B1 rolled over main drain covers and uneven floor transitions without getting stuck. The WYBOT App supports OTA firmware updates and scheduling. At 19 pounds, it is one of the lighter cordless units we lifted, which is a real plus on day 30 of testing.
Navigation is the weak spot. The B1 sometimes repeats areas and misses corners, especially on the first few cycles before it learns the pool. Wall climbing performance varies depending on pool surface – it climbed gunite reliably but slipped occasionally on smooth fiberglass. The 1-hour quick mode drains the battery fast, so use it sparingly.
Who should buy this
If you want a cordless pool robot with serious brush power at a friendly price, the WYBOT B1 is our best value pick. It is a strong choice for small to medium inground pools and for owners who want app control without the flagship price.
Who should skip this
If your pool is large or you need flawless navigation on every cycle, spend a little more on the WYBOT C1 or Aiper Scuba S1. If you do not need app control at all, the Dolphin Nautilus CC is a simpler option.
8. Aiper Scuba S3 – Best for Waterline Scrubbing
Aiper Scuba S3 Robotic Pool Cleaner for Inground Pools, 5 Modes, Pale Blue
Cordless
240 min ECO runtime
Waterline scrubbing 2 inches above
3-micron fine filter
Pros
- Waterline scrubbing 2 inches above surface
- Smart sensor path planning
- Dual ultra-fine 180-micron plus 3-micron filtration
- Auto-parking at waterline with app alert
- Up to 240 min runtime in ECO mode
Cons
- App disconnects when submerged
- Cannot clean steps fully
- Heavy when retrieved with water
The Aiper Scuba S3 is the highest-rated cordless robotic pool cleaner we tested, and after 90 days it is easy to see why. Its aggressive waterline scrubbing reaches 2 inches above the waterline – further than any other cordless unit we ran. If algae at the waterline is your pet peeve, the S3 attacks it head-on.
Smart sensor path planning maps the pool and runs structured coverage patterns. In our test pool the S3 finished the floor in a methodical pattern rather than the random bouncing we saw on cheaper units. Auto-parking at the waterline with app alerts made retrieval painless.
ECO Mode delivers up to 240 minutes of runtime per charge. For a 30 to 40-foot pool, that is more than enough to complete a full floor, wall, and waterline cycle. The dual ultra-fine filtration (180-micron plus 3-micron) captured everything from leaves to algae spores. At 18 pounds, the S3 is also one of the lighter cordless options in its class.
App connectivity drops when the unit is submerged – that is normal for any pool robot, but worth noting. The S3 cannot fully clean pool steps, so you will still need a quick manual brush on the steps. When the basket is full of water, the unit is heavier than its dry weight suggests.
Who should buy this
If waterline algae is your main cleaning headache, the Aiper Scuba S3 is the cordless robotic pool cleaner we recommend. It is also a strong all-around pick for medium inground pools where a long runtime and fine filtration matter.
Who should skip this
If you need step or sun-shelf cleaning, none of the current generation of cordless pool robots handle those well – you will need manual brushing regardless. If you want a simpler cordless pick, the WYBOT B1 is easier to operate.
How to Choose the Right Robotic Pool Cleaner
Buying a robotic pool cleaner for an inground pool is a longer-term decision than most pool accessories. A good unit lasts 5 to 7 years. A bad one fails in 18 months. Here is what our team learned after 90 days of testing 8 models in three pools.
Corded vs Cordless: The Real Trade-Off
Corded robotic pool cleaners like the Dolphin Nautilus CC and Dolphin Cayman deliver consistent power, longer cycles, and proven long-term durability. Most corded Dolphin owners on Reddit report 3 to 5 years of daily use with only minor part replacements. The trade-off is the cable – it can tangle, it limits where you store the power supply, and it crosses the pool deck.
Cordless robotic pool cleaners like the WYBOT C1, Aiper Scuba S1, and Beatbot-style units free you from the cable. They dock and recharge, run on lithium-ion batteries, and connect to apps. The trade-off is battery life – cordless units typically run 90 to 270 minutes per charge versus unlimited runtime for corded models. Real-world battery life also degrades after 2 to 3 seasons, while corded motors last 5 to 7 years.
Safety note: the CPSC has issued recalls for certain cordless pool robots with lithium-ion batteries. Check current recall lists before purchasing any cordless unit, and never charge a cordless pool robot unattended or overnight.
Filtration: Standard Mesh vs NanoFilters vs MicroMesh
Standard mesh filters (around 180 microns) catch leaves, acorns, hair, and large debris but let fine silt, pollen, and algae spores pass through. NanoFilters (around 3 to 5 microns) and MicroMesh filters catch what standard mesh misses, which is why pool water looks visibly clearer after one cycle on a NanoFilter-equipped unit. For inground pools with visible algae or cloudy water, NanoFilters or MicroMesh are worth the upgrade.
Waterline Cleaning: Why It Matters
The waterline is the band where water meets tile, and it is where roughly 90 percent of pool algae starts. A robotic pool cleaner that climbs walls and scrubs the waterline will keep your pool looking cleaner with less manual brushing. In our testing, the Aiper Scuba S3 reached 2 inches above the waterline, the Dolphin Nautilus CC consistently cleaned the full waterline, and the Aiper Scuba S1 performed well in standard waterline cleaning. If algae at the waterline is your pet peeve, prioritize this feature.
Pool Size and Cable Length
Most inground pools in the U.S. are 30 to 40 feet long. For those pools, a 50-foot cable is enough to reach every corner with some slack to spare. For pools longer than 40 feet, look for a 60-foot cable or a cordless unit with at least 180 minutes of runtime. Anti-tangle swivels are a must-have on any corded unit – without one, the cable will twist and shorten over time.
Pool Surface Compatibility: Vinyl, Gunite, and Fiberglass
Most modern robotic pool cleaners handle all three common inground pool surfaces. Vinyl liners are the most forgiving – any rubber or PVC brush works. Gunite and concrete are abrasive and need sturdy active brushes, which Dolphin HyperBrush and Aiper dual-brush designs handle well. Fiberglass is smooth, so wall climbing performance varies – in our testing the WYBOT C1 and Aiper Scuba S1 climbed fiberglass more reliably than the WYBOT B1.
Weekly Smart Timer and Automation
Weekly smart timers let you program the cleaner to run every day, every other day, or every third day without touching it. This is the single biggest time-saver feature for busy pool owners. The Dolphin Cayman has one of the simplest weekly timers in the industry. App-controlled models add remote scheduling, cleaning history, and sometimes notifications.
Saltwater vs Chlorine Compatibility
All 8 robotic pool cleaners in this guide handle both saltwater and chlorine pools. Saltwater is slightly more corrosive over time, so rinse the power supply, cables, and the unit itself with fresh water after each cycle. Check the warranty for saltwater-specific language if your pool runs above 3,500 ppm salinity.
Long-Term Durability and Parts
Dolphin corded models are the durability benchmark. The Nautilus CC, Cayman, and Premier all use commercial-grade motor platforms with replaceable brushes, tracks, and filter baskets. Expect 5 to 7 years from a corded Dolphin with reasonable care. Cordless units typically last 2 to 4 seasons before battery degradation becomes noticeable, though firmware updates can extend useful life. Look for manufacturers that stock replacement parts – tracks, brushes, impellers, and filter baskets – so you can repair instead of replace.

Frequently Asked Questions
What is the best robotic pool cleaner for a concrete pool?
For a concrete (gunite) inground pool, our team recommends the Dolphin Nautilus CC. Its active scrubbing brush handles abrasive concrete surfaces well, it climbs walls reliably, and it scrubs the waterline where algae tends to start. The Aiper Scuba S1 is a strong cordless alternative if you want a battery-powered unit instead.
What are common problems with robot pool cleaners?
The most common problems are tangled power cords on corded models, batteries that lose runtime on cordless units, standard mesh filters that clog with fine silt, units getting stuck on main drain covers, and the inability to clean pool steps or sun shelves fully. Anti-tangle swivels, NanoFilters, and weekly smart timers solve most of these issues.
Are robotic pool cleaners worth it?
Yes, robotic pool cleaners are worth it for most inground pool owners. They cut weekly cleaning time by several hours, lower chemical use, reduce wear on your pool main filter, and produce visibly clearer water. Most owners recoup the cost within two seasons by reducing professional cleaning visits.
Do robotic pool cleaners pick up leaves?
Yes, every robotic pool cleaner in this roundup picks up leaves. For light leaf loads, any model works. For heavy leaf loads (acorns, large leaves after a storm), choose a model with a large top-load filter bin like the Dolphin Nautilus CC or BOTLIFE PC10, or a model with a dedicated leaf bag option.
Can you leave a robotic pool cleaner in a swimming pool?
Yes, you can leave a robotic pool cleaner in the pool between cycles, especially corded models designed for set-and-forget operation. For cordless units, remove after each cycle and store on the charging dock. In hot sun, prolonged submersion can degrade plastic components over time, so most manufacturers recommend removing the unit when not in use for extended periods.
How often should I use my robotic pool cleaner?
Most pool owners run their robotic pool cleaner 2 to 3 times per week during swim season. Heavy debris pools (under trees, in windy areas) may need daily cycles. Pools with low debris can run every 3 days. Weekly smart timers automate this so you can set it once and forget it.
How long do robotic pool cleaners last?
Corded robotic pool cleaners like the Dolphin Nautilus CC and Dolphin Cayman typically last 5 to 7 years with reasonable care. Cordless robotic pool cleaners last 2 to 4 seasons before battery degradation becomes noticeable. Replaceable brushes, tracks, and filter baskets extend the useful life of either type.
Final Verdict
After 90 days of testing across vinyl, gunite, and fiberglass pools, our team crowned the Dolphin Nautilus CC as the best robotic pool cleaner for in-ground pools for 2026. It is reliable, energy efficient, and consistently delivers a clean pool with zero babysitting. If you want a cordless alternative, the WYBOT C1 is our premium cordless pick and the WYBOT B1 is our best value. For waterline-focused cleaning, the Aiper Scuba S3 is hard to beat.
