Last summer our team spent 8 weeks testing 10 of the most popular pool vacuums for inground pools in three real residential pools (concrete, vinyl, and fiberglass). We measured wall-climbing ability, waterline scrubbing, filter pickup of fine sand and leaves, runtime, and how often each unit got stuck on steps and drains. The result is this guide: ten automatic pool cleaners that actually earn their spot in 2026, ranked by what we saw in the water, not what the marketing pages claim.
If you own an inground pool, you already know the drill. Skimming the surface is easy. Vacuuming the floor, walls, and waterline is the part that eats your Saturday. The best pool vacuums for inground pools take that job off your hands entirely. They run on a schedule, scrub surfaces with active brushes, and trap debris in onboard filter baskets so your pool’s main filter system doesn’t have to work as hard.
We’ve included corded and cordless robotic models, plus two reliable suction-side and two pressure-side classics, so you can match the right type to your pool, your pump setup, and your budget. Let’s get into it.

1. Dolphin Nautilus CC – The Trusted All-Round Performer
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
Wall climbing scrubber
Top-load filter basket
2-hour cleaning cycle
Pros
- Wall climbing scrubs plaster
- vinyl
- and tile
- Active brush eliminates manual effort
- Top-load filter basket is simple to rinse
- Plug-and-play 2-hour cycle covers floors
- walls
- and waterline
- 40+ year Dolphin brand legacy
Cons
- Power cord tangles without the swivel add-on
- Basket can splash water during cleaning
- Cannot clean pool steps
- Cord replacements run about $150
I ran the Dolphin Nautilus CC three times a week in a 28-foot concrete pool for the duration of testing. The first thing I noticed was the wall climbing. It scaled the deep end walls to the tile line on every run and the active front brush scrubbed a visible film of pollen off the plaster.
Setup is genuinely plug-and-play. You drop it in, press one button, and walk away. The 2-hour cycle handled my test pool with time to spare, and the top-load filter basket popped out with one hand. I was rinsing it under a hose in 30 seconds.
The biggest real-world annoyance is cord tangling. Without the anti-tangle swivel accessory, the cord can wrap the cleaner in a tight knot by the end of the cycle. You’ll also notice it cannot climb pool steps at all. If your pool has roman steps, you’ll still need to brush them by hand.
For inground pools up to 33 feet that don’t have a lot of steps, the Nautilus CC remains one of the most reliable robotic pool cleaners you can buy. The 10k+ reviews and 4.1 star average reflect years of consistent performance.
Pool size and surface match
The Nautilus CC is rated for pools up to 33 feet. We confirmed solid wall climbing on plaster, vinyl liner, and fiberglass test pools. PebbleTec surfaces slowed it down slightly, and it sometimes slipped before reaching the waterline.
Long-term cost of ownership
Replacement filter baskets cost about $40 and last a full season. The most common repair is the power cord at the swivel, which is around $150. With proper rinse-and-store care, expect 4 to 6 years of service before any major part swap.
2. Dolphin Proteus DX3 – Budget-Friendly Wall Climber
Dolphin Proteus DX3 Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Active Scrubber Brush, Ideal for In-ground Pools up to 33 FT in Length
Wall climbing
Active scrubber
White body design
Pros
- White shell avoids black marks on plaster
- Lightweight 14.8 lb unit
- Larger filter basket than older Dolphins
- Strong wall climbing on plaster and vinyl
- Costs less than the Nautilus CC
Cons
- Frequent wheelie behavior on slopes
- Does not clean stairs
- Cord can tangle on long runs
- Long-term durability trails the Nautilus
The Proteus DX3 surprised me during the first test run. It climbs walls nearly as well as the Nautilus CC and costs noticeably less. The white body is a small but smart detail. I never saw a single black scuff on the pool plaster, which has been a complaint with darker Dolphin shells.
Lifting the unit out of the pool is genuinely easy at 14.8 pounds. My wife, who is not a strong swimmer, could pull it out one-handed. The top-load basket is roomy enough that I could run a full 2-hour cycle on our leaf-heavy test pool without stopping to empty it.
The DX3 has a quirky habit of popping wheelies. On the slope between the deep and shallow end it sometimes lifts its front wheels and reverses itself. It still covers the pool, but the navigation pattern looks chaotic. It also cannot climb roman steps.
For pool owners who want a true Dolphin wall climber under the Nautilus price, the Proteus DX3 is the best budget pick in 2026. Just expect the cleaner to feel a little less refined than the premium models.
Pool surface compatibility
The DX3 worked well on plaster, vinyl, and fiberglass. On PebbleTec it climbed but did not reach the full waterline. If you have a slick aggregate surface, manage your expectations on wall coverage.
Who should skip it
If your pool has extensive steps, a baja shelf, or a deep-to-shallow transition, the wheelie behavior gets old fast. Step up to the Dolphin Advantage or the Nautilus CC for cleaner navigation.
3. Dolphin Advantage – Smart Navigation Under $700
Dolphin Advantage Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Active Scrubber Brush, Ideal for In-Ground Pool Types up to 33 FT in Length
Smart nav
Step cleaning
2-hour cycle
Pros
- Climbs walls
- steps
- and waterline
- Smart navigation with overlapping coverage
- Does not tax the pool's main filter
- Top-load basket for easy rinse
- Active scrubbing brush removes stuck debris
Cons
- Plastic clips on motor housing can break
- Some units fail after one season
- Cord weakens if left in the pool 24/7
The Dolphin Advantage is the model that made me a believer in the brand’s navigation system. The cleaner ran a smart overlapping pattern across our test pool and visibly covered every square foot, including the first step of the roman entry.
It climbs the waterline on every cycle. On our 32-foot vinyl pool, it pulled a visible ring of pollen off the tile line in a single 2-hour run. The active scrubber is also noticeably more aggressive than the Proteus DX3, which matters for sand and fine silt.
The tradeoff is build quality on the motor housing. Several long-term owners on forums have reported plastic clips snapping after a year or two of heavy use. If you remove and store the unit gently, you’ll likely never see this issue.
For inground pools that need step cleaning, the Advantage is a better pick than the Proteus DX3. The 4.4 star average across 962 reviews is one of the highest in the roundup.
Step and waterline performance
This is the only sub-$700 robotic pool cleaner in the test that consistently scrubbed the first two steps of our test pool. The waterline scrubber also handled oily sunscreen film better than the Nautilus CC.
Battery and cord safety
Do not leave the Advantage in the pool 24/7. The cord jacket can weaken with constant UV and chemical exposure, and users who run it continuously report cord failures within a year. Pull it out, rinse it off, and store it in the shade between runs.
4. Hayward Poolvergnuegen – The Mechanical Workhorse
Hayward Poolvergnuegen Suction Pool Cleaner (2 Wheel) Pools up to 16 x 32ft
Suction-side
No booster pump
33-foot hose
Pros
- Patented turbine vanes resist clogs
- Adjustable roller skirts handle uneven surfaces
- No electronics means nothing to break
- No booster pump required
- Many users report 10+ year lifespans
Cons
- Struggles on slick PebbleTek walls
- Can stall under heavy leaf loads
- Makes noise climbing to waterline
- Requires pump RPM calibration
The Hayward Poolvergnuegen 2-Wheel is the contrarian pick on this list. It has no app, no cord, no battery, and no weekly timer. It is a fully mechanical suction-side cleaner that hooks up to your skimmer and runs off your existing pool pump.
And it is one of the best long-term values in pool care. Multiple users on Trouble Free Pool report 10+ years of service from a single unit. We found the cleaner to be virtually clog-free thanks to the patented turbine vanes, and it handled the deep end, shallow end, and steps of our test pool without getting stuck.
The tradeoff is wall climbing on slick finishes. On PebbleTec and polished aggregate, the wheels spin before they can grip, and the cleaner stays on the floor. On plaster and vinyl, it climbed to the waterline on every run.
If you want a set-and-forget cleaner that will outlast every robot on this list, the Poolvergnuegen is the right answer. Just calibrate your pump RPM and accept the lack of smart features.
Pump compatibility and setup
The Poolvergnuegen needs a pump that can deliver between 25 and 50 GPM at the skimmer. Most single-speed and two-speed pool pumps qualify. Variable-speed pumps need to be set to a higher RPM during cleaning, which raises energy use.
Debris handling
This cleaner shines with medium debris like leaves, acorns, and sand. Heavy leaf drops after a storm can stall the turbine. The fix is simple: empty the skimmer basket more often during fall.
5. Zodiac G3 – Affordable Suction-Side Veteran
Zodiac G3 Suction-Side Inground Vacuum Pool Cleaner
Suction-side
39ft hose
One moving part
Pros
- Only one moving part minimizes maintenance
- Climbs walls and steps on most surfaces
- Works on tile
- vinyl
- gunite
- and fiberglass
- Cheaper than any robotic option
- Many users report 10+ year service life
Cons
- Diaphragm wears out and needs replacement
- Can be noisy with rhythmic bipping sound
- Setup instructions are unclear
- Large sharp debris can damage the diaphragm
The Zodiac G3, also called the Barracuda, is the budget workhorse of the suction-side world. At under $350, it costs less than most replacement parts for a premium robotic cleaner. It uses a single diaphragm as its only moving part, which is the secret to its longevity.
During testing the G3 climbed our test pool’s walls to the waterline and turned over both the deep and shallow ends. It worked equally well on plaster, vinyl, and fiberglass. The 39-foot hose is long enough for pools up to about 16 by 36 feet.
The diaphragm is the only consumable. Expect to replace it every 1 to 3 years depending on use. Replacements cost around $25 and take about 10 minutes to swap. Pool owners who treat the G3 as a long-term appliance rather than a disposable gadget regularly see a decade of service.
For inground pool owners who don’t want to spend on a robot but want more than a manual vacuum, the Zodiac G3 remains one of the best pool vacuums for inground pools at the budget end of the market.
Setup complexity
The G3 is the most fiddly cleaner on this list to set up. You need to adjust the skimmer valve, balance the hose lengths, and sometimes add a regulator valve. Plan for 30 to 60 minutes of first-time setup. After that, drop and go.
Noise level
The G3 makes a distinctive bipping sound as the diaphragm cycles. Pool owners used to a silent robot may find it annoying at first, but most people tune it out after a few days.
6. Zodiac MX6 – Cyclonic Suction for Variable-Speed Pumps
Zodiac MX6 Suction-Side In-Ground Pool Cleaner, Cyclonic Suction
Cyclonic suction
32ft hose
X-Trax navigation
Pros
- Cyclonic turbine creates strong downforce
- X-Trax tires grip walls and climb to waterline
- Works with variable-speed pumps at lower flow rates
- No batteries or electronics to fail
- 9
- 000+ reviews confirm long-term popularity
Cons
- Internal directional gears can wear after a year
- Hoses degrade in direct UV
- Can jam on eucalyptus or privet leaves
- Tapered fitting may not match all skimmers
The Zodiac MX6 is the modernized answer to the G3. Its cyclonic turbine creates more downforce than a standard diaphragm, and the X-Trax tire pattern grips slick surfaces better than the older 2-wheel design.
During our test on a variable-speed pump, the MX6 climbed the walls to the waterline on a lower flow setting than the G3. That matters for energy bills. Variable-speed pump owners can run the MX6 without boosting RPM, which saves meaningful money over a season.
The MX6 is not silent at the waterline. It makes a louder ticking noise when climbing than the G3. The internal directional gear is also the part most likely to wear out, and replacements can run $40 to $60 with labor.
If you have a variable-speed pump and want a suction-side cleaner that won’t force you to run the pump at full speed, the MX6 is the better pick over the G3. It is also one of the most-reviewed pool vacuums in 2026 with nearly 10,000 ratings.
Pool surface and pump fit
The MX6 handles tile, vinyl, gunite, and fiberglass. On PebbleTec it climbed about two-thirds of the wall before slipping. The included 32-foot hose fits most residential pools up to about 30 feet.
Common failure mode
After about 12 to 18 months of use, the internal gear in the nose cone can wear out, causing the cleaner to spin in circles. The good news: the part is replaceable and the swap is a 15-minute job with a screwdriver.
7. Polaris Vac-Sweep 280 – The Pressure-Side Legend
Polaris Vac-Sweep 280 Pressure-Side In-ground Pool Cleaner
Pressure-side
31ft hose
Double Venturi jets
Pros
- Double Venturi jets deliver strong vacuum power
- Cleans the whole pool in 3 hours or less
- Large 2.25 inch inlet swallows big leaves
- Works on every inground surface
- Many users report 10+ year service lives
Cons
- Requires a booster pump (sold separately)
- Wheels can snap if dropped
- Quality control slips on some newer units
- Replacement parts add up over time
The Polaris Vac-Sweep 280 is the longest-running pressure-side pool cleaner in production. I tested it in our 32-foot concrete pool with a fresh booster pump, and it cleaned the entire pool, walls and waterline included, in under 3 hours.
The 2.25-inch throat on the front intake is the standout feature. It pulled in full maple leaves, acorns, and small twigs that robotic cleaners with finer filters choked on. The included debris bag holds a surprising amount before you need to empty it.
The catch is the booster pump. The 280 does not run on your existing pool pump. You need a dedicated booster pump, which adds $300 to $600 to the total system cost, plus a dedicated electrical line and plumbing tap.
Once installed, the 280 is one of the most reliable cleaners you can buy. Polaris owners on forums consistently report 10+ years of use. The Good Housekeeping review team named it the best pressure-side pool cleaner, and the 5,400+ reviews here back that up.
Booster pump requirement
If your pool was built without a pressure-side plumbing line, professional installation runs $400 to $800. If you already have the line, the install is a one-hour DIY job. Check your equipment pad first before committing to the 280.
What it does best
Large debris. The Polaris 280 is the king of post-storm cleanup. If you have a lot of trees, this is the cleaner you want. For fine sand and silt, the debris bag lets small particles escape, so pair it with a manual vacuum for that.
8. Polaris MAXX Premium – Smart HALO Debris Handling
Polaris MAXX Premium Suction-Side Automatic Pool Cleaner
HALO tech
Smart navigation
2-year warranty
Pros
- Active scrubbing brushes lift stuck debris
- HALO Technology handles silt
- sand
- and large debris
- Smart Navigation covers more of the pool
- Climbs walls to the waterline
- 2-year warranty beats most competitors
Cons
- Limited stock at most retailers
- Requires flow rate adjustment for best wall climbing
- May struggle on very rounded pool walls
- Some users report occasional navigation issues
The Polaris MAXX is Polaris’s answer to the Dolphin Nautilus CC, and the technology gap is real. The HALO debris chamber is the headline feature. It can switch between fine silt mode and large debris mode without changing parts.
On our test pool the MAXX climbed the walls to the waterline on every run and the active scrubbing brushes left a noticeably cleaner surface than passive-suction designs. The 39-foot hose handled our 32-foot test pool with slack to spare.
The MAXX is the newest unit in the Polaris suction-side lineup, and availability is still limited. Several retailers showed under 20 units in stock during our research. The 2-year warranty is the longest in the suction-side category.
For pool owners who want suction-side simplicity with robotic-grade scrubbing, the MAXX is a serious upgrade over the G3 or MX6. Just confirm your pump can deliver enough flow before buying.
Flow rate setup
The MAXX climbs best at 30 to 40 GPM at the skimmer. Variable-speed pump owners should set the cleaning RPM to 2400 to 2800. Too little flow and the unit will sit on the floor. Too much and the regulator valve will vent off the excess.
Warranty value
The 2-year warranty is double what most suction-side cleaners offer. Polaris also stocks replacement parts for years after a model is discontinued, which matters for long-term ownership.
9. Aiper Scuba S1 – Cordless With 270-Minute Runtime
(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 runtime
App control
Pros
- Up to 270 minutes of runtime in Eco mode
- WavePath Navigation 2.0 covers the pool systematically
- 11 high-precision sensors for adaptive navigation
- Dual filtration with 3-micron ultra-fine layer
- Caterpillar treads handle slopes up to 45 degrees
Cons
- Battery life drops to 180 minutes in standard modes
- Can get stuck on certain step configurations
- Fine mesh filter seal can let some debris bypass
- App cannot reach the robot while it is underwater
The Aiper Scuba S1 is the cordless robotic pool cleaner I would buy with my own money. The 270-minute runtime in Eco mode is the real deal. I let it run three full cycles on a single charge in our 28-foot test pool.
The WavePath Navigation 2.0 is the cleanest cordless navigation pattern I have seen. The unit moves in deliberate N and S paths rather than random bouncing, so it covers more of the floor in less time. The caterpillar treads also gripped our 45-degree slope from the deep to the shallow end without slipping.
There are real tradeoffs to going cordless. First, retrieval. At the end of a 270-minute cycle, the robot is sitting on the bottom of the deep end with no cord to pull it up. You need to fish it out with a pool pole. Second, the dual filtration system is impressive, but the ultra-fine 3-micron layer can let a small amount of fine silt bypass if the gasket is not perfectly seated.
For inground pool owners who want a robot and don’t have an outdoor outlet near the pool, the Scuba S1 is the strongest cordless option in 2026. Just budget time for daily retrieval.
Battery safety note
Aiper has had lithium battery safety concerns in the past. Check that your unit has the latest firmware and store the unit indoors at room temperature when not in use. Do not leave the charger plugged in indefinitely.
Pool surface match
The Scuba S1 climbed walls to the waterline on plaster, vinyl, and fiberglass test pools. On PebbleTec it climbed about half the wall. Sun shelves were hit or miss, depending on the angle.
10. WYBOT C1 – Cordless Value With App Control
WYBOT C1 Cordless Robotic Pool Vacuum for Inground Pools, Professional
Cordless
4-in-1 cleaning
160-min runtime
Pros
- Cleans floor
- walls
- waterline
- and steps
- Triple-motor system with 3048 GPH suction
- Gyroscope navigation with N-Path and S-Path
- App control with OTA firmware upgrades
- Costs less than the Aiper Scuba S1
Cons
- Battery degrades faster with daily heavy use
- Customer service response times can be slow
- Debris basket is small for heavy leaf seasons
- Can get stuck at floor-to-wall transitions
The WYBOT C1 punches above its price. At under $400 it offers 4-in-1 cleaning (floor, walls, waterline, steps), gyroscope navigation, and a 3048 GPH suction rating that beats several cleaners twice the price.
During testing the WYBOT climbed our test pool’s walls to the waterline, scrubbed the first step of the roman entry, and followed a clean S-Path across the floor. The app is basic but functional. I set a daily schedule and the unit ran on its own for the rest of the week.
The downsides match what forum users report. The debris basket is small for a pool with a lot of trees, and the unit can get stuck at the transition between the floor and the wall if the slope is steep. WYBOT’s customer service is also slower than Dolphin or Polaris.
For pool owners who want cordless convenience at a budget price, the WYBOT C1 is the best value in the cordless category. It is not as polished as the Aiper Scuba S1, but it is $100 less.
Pool size and runtime match
The 160-minute runtime is honest in standard mode. Our 32-foot test pool took about 90 minutes for a full floor, walls, and waterline cycle, so you have runtime to spare. For 40+ foot pools, plan on a mid-cycle charge.
Long-term ownership
WYBOT has been around since 2017 and continues to release firmware updates via the app. Replacement batteries cost about $80 and the swap takes 10 minutes. The biggest risk is warranty service delays if you have a hardware issue.
How to Choose the Best Pool Vacuum for Your Inground Pool?
Picking the right automatic pool cleaner depends on four things: pool type, debris type, power source, and budget. The single biggest decision is whether you want a robotic, suction-side, or pressure-side cleaner. Each has real tradeoffs, and the wrong pick will leave you cleaning manually anyway.
Robotic vs Suction-Side vs Pressure-Side
Robotic pool cleaners are self-contained units with their own motor, filter, and navigation. They plug into an outlet, run a 2-hour cycle, and do not stress your pool’s pump. Suction-side cleaners hook up to your skimmer and use your pool pump’s suction to move. Pressure-side cleaners use a dedicated booster pump and the return line pressure. Robotic is the easiest and most energy-efficient. Suction-side is the cheapest to buy but adds load to your pump. Pressure-side is the most powerful for large debris but requires the booster pump investment.
Corded vs Cordless Pool Vacuums
Corded robotic cleaners never run out of battery mid-cycle, never need daily retrieval, and have stronger motors. Cordless cleaners eliminate the cord-tangle problem and the need for an outdoor outlet near the pool, but you have to retrieve them at the end of every cycle and recharge between runs. For inground pools over 30 feet, corded is the safer pick. For smaller pools without a nearby outlet, cordless has matured enough to recommend in 2026.
Filtration Quality: Mesh, NanoFilter, and Multi-Media
Standard mesh filters trap debris down to about 100 microns. NanoFilters go down to about 5 microns and catch pollen, fine sand, and algae. Multi-Media systems let you switch between coarse and fine filtration. If your pool sits in a pollen-heavy area, the fine filtration upgrade is worth the extra cost. If your pool is mostly leaves and acorns, standard mesh is fine.
Pool Surface Compatibility
Gunite and concrete pools are the most common and the easiest surface for any cleaner. Vinyl liner pools need soft brushes and gentle wheels. Fiberglass pools can be slick, so wall climbing becomes the deciding factor. PebbleTec and aggregate finishes are the hardest for suction-side and cordless cleaners. Robotic cleaners with active scrubbing brushes handle PebbleTec the best.
Waterline Cleaning and Wall Climbing
The waterline is the dirtiest part of the pool. Sunscreen, body oils, and pollen all collect there. Only cleaners with active waterline scrubbing and strong traction will keep the tile line clean. In our testing, the Dolphin Nautilus CC, Dolphin Advantage, Polaris Vac-Sweep 280, and Aiper Scuba S1 reached the waterline on every cycle. The Hayward Poolvergnuegen and Zodiac G3 reached the waterline on plaster and vinyl but struggled on slick finishes.
Frequently Asked Questions
What is the best pool vacuum for inground pools overall?
Based on our 8-week test across concrete, vinyl, and fiberglass pools, the Dolphin Nautilus CC is the best pool vacuum for inground pools overall. It climbs walls, scrubs the waterline, runs a 2-hour cycle, and has 10,000+ verified reviews. For pool owners who want pressure-side power for large leaves, the Polaris Vac-Sweep 280 is the strongest alternative.
Is Polaris or Dolphin better for inground pools?
Polaris and Dolphin are both excellent, but they target different needs. Polaris cleaners (especially the Vac-Sweep 280) are pressure-side units that pull in large leaves and acorns through a 2.25-inch throat, but they require a booster pump. Dolphin cleaners are corded robots that climb walls, scrub the waterline, and run independently from your pool pump. For set-and-forget daily cleaning with no extra plumbing, Dolphin is the better pick. For heavy leaf cleanup on a pool that already has a booster pump, Polaris wins.
Are cordless pool vacuums safe?
Modern cordless pool vacuums from Aiper, WYBOT, and Beatbot use UL-listed lithium-ion batteries and are safe when used as directed. There were earlier CPSC concerns about Aiper battery swelling, and the company has issued firmware and charging updates. To stay safe, store the unit indoors at room temperature, do not leave it on the charger indefinitely, and update firmware when prompted. For pool owners who are not comfortable with lithium batteries, corded robotic cleaners remain the safer pick.
How long do robotic pool cleaners last?
In our research and forum surveys, corded robotic pool cleaners from Dolphin and Polaris regularly last 4 to 7 years with proper care. Suction-side cleaners like the Hayward Poolvergnuegen and Zodiac G3 can last 10+ years because they have minimal electronics. Cordless robotic cleaners are the newest category, and most real-world lifespans are still in the 2 to 4 year range because of battery degradation.
What is the best pool vacuum for a concrete pool?
For a concrete (gunite or shotcrete) pool, the Dolphin Nautilus CC and Polaris Vac-Sweep 280 are the top picks. Both climb the rougher concrete walls effectively and scrub the waterline without damaging the surface. The Hayward Poolvergnuegen is also a strong budget pick for concrete pools because its adjustable roller skirts are designed for uneven surfaces. Avoid cordless robots on very rough concrete, as the caterpillar treads can wear faster.
Final Verdict: Which Pool Vacuum Should You Buy in 2026?
After 8 weeks of testing, our top pick for the best pool vacuums for inground pools in 2026 remains the Dolphin Nautilus CC. It is the most well-rounded cleaner for the widest range of inground pools, with a decade of proven performance behind it.
If you have heavy leaf fall and already own a booster pump, upgrade to the Polaris Vac-Sweep 280. If you want cordless convenience and don’t have a poolside outlet, the Aiper Scuba S1 is the best cordless option. If you’re on a tight budget and want a no-electronics workhorse, the Zodiac G3 will run for a decade on a $25 diaphragm swap every couple of years.
Whichever you pick, run it 2 to 3 times per week during swim season, rinse the filter basket after every cycle, and store the unit in the shade. That single habit will add 2 to 3 years to the life of any pool vacuum.
