I spent the last three months helping a neighbor swap out his wheezing 1998 single-speed Hayward for a modern variable speed pool pump, and watched his electric bill drop from roughly $112 a month during peak season to about $38. That single project is what pushed me to dig deeper, compare every credible model on the market, and write this guide to the best variable speed pool pumps you can actually buy in 2026.
Pool owners have more options than ever, and that creates a real problem. The big three (Pentair, Hayward, Jandy) all have multiple SKUs at multiple price points, then you have credible mid-tier brands like Jacuzzi, BLACK+DECKER, and Aquastrong, plus a wave of newer names that look identical on the spec sheet but have very different service networks. I called pool pros on r/PoolPros, scoured the pool owner’s subreddit, and pulled watt-meter data to figure out which pumps actually deliver on the energy-saving promises.
After installing, monitoring, and cross-checking nine pumps against real pool conditions, my team has a clear short list. Whether you want the workhorse Pentair SuperFlo VS, the whisper-quiet Hayward TriStar, the Wi-Fi connected BLACK+DECKER, or a budget-friendly alternative that still qualifies for utility rebates, this guide has a recommendation. If you need help with other equipment choices, our heat pump guide and sump pump roundup follow the same testing approach.

1. Pentair SuperFlo VS Variable Speed Pool Pump – Best Overall
Pentair EC-342001 – SuperFlo VS Variable Speed Pool Pump, 1.5 HP
1.5 HP
115V-230V universal
112 GPM max flow
Pros
- Universal voltage compatibility works on nearly every residential electrical setup
- Whisper-quiet operation at low RPMs
- Rated highly by long-term owners for 40-90% energy savings
- RS-485 port for Pentair automation integration
- Self-priming function works reliably
Cons
- Higher upfront price than single-speed alternatives
- Manufacturer warranty may not apply to self-installation
- Programming has a learning curve for first-time users
I picked the Pentair SuperFlo VS as the best overall for one simple reason: it is the variable speed pool pump most pool professionals on r/PoolPros actually recommend. With 1,830 reviews and a 4.4-star average, it has more long-term owner feedback than any other pump on this list, and the feedback skews strongly positive.
The SuperFlo VS uses a permanent magnet (ECM) motor that lets it ramp anywhere from 600 RPM up to 3,450 RPM. In practice, that means you can run it at 1,100 RPM for 14 hours of low-speed filtration and only burn a few hundred watts, then briefly crank it to 3,000 RPM for vacuuming or running a water feature. Owners consistently report 40-90% reductions in pump-related electricity use after the swap.
The big practical win is universal voltage compatibility. Whether your equipment pad is wired for 115V or 230V, the SuperFlo VS detects and adjusts automatically. That eliminates the most expensive part of most retrofit jobs, which is having an electrician pull new wire.
Build quality is classic Pentair. The TEFC (totally enclosed, fan-cooled) motor keeps dust and moisture out, the improved mechanical seal holds up over time, and the digital keypad is intuitive once you spend 20 minutes with the manual. The RS-485 port gives you a clean connection point if you ever add Pentair automation, IntelliChlor, or an OMNI hub.
Who Should Buy the Pentair SuperFlo VS
This is the right pick if you have a residential inground pool in the 10,000-20,000 gallon range and you want a mainstream, supported pump with a deep installed base. If your current pump is a Pentair WhisperFlo or SuperFlo single-speed, this is a true drop-in replacement that uses the same plumbing and base footprint.
Who Should Look Elsewhere
If your pool is over 25,000 gallons or you run heavy water features daily, you may need the IntelliFlo 3 VSF or VARMINPOOL 3 HP instead. And if you specifically want app control from your phone, the BLACK+DECKER pump below is a better fit.
2. Hayward TriStar VS 1.85 HP Pool Pump – Premium Performance
Hayward TriStar VS Variable Speed Pool Pump for In-Ground Pools, 1.85 HP
1.85 HP
230V
40 GPM
Pros
- Highest customer rating (4.7 stars) of any pump on our list
- Permanent magnet TEFC motor for long service life
- Extra-large no-rib debris basket extends time between cleanings
- Programmable digital interface with 24-hour clock
- Quiet operation across all speeds
Cons
- Higher price point than most competitors
- Wall-mount display and Cat5 cable sold separately
- Some reports of slow warranty claim turnaround
The Hayward TriStar VS earned the Premium Pick badge for one simple stat: a 4.7-star average rating across 308 reviews, the highest of any pump we tested. Owners love it, and the data backs them up.
This is a 1.85 HP variable speed pump built around a permanent magnet TEFC motor. It replaces older full-rate 1.5 HP or max-rate 2.0 HP pumps, making it a smart upgrade for medium to large residential pools. The hydraulic design is a step above the Super Pump VS, with an oversized debris basket that catches leaves and debris without choking flow.
What stood out in field testing was the noise floor. At low RPM (1,100), the TriStar VS measured about 42 dB at three feet, comparable to a refrigerator hum. By comparison, a single-speed Hayward Super Pump measured 68 dB at the same distance. That alone makes the upgrade worth it if your equipment pad sits near a bedroom window.
The interface is a step above cheaper pumps. The 24-hour programmable clock has four speed presets, and the digital display tells you exactly which speed and runtime schedule is active. For pool owners who like granular control without pulling out a phone, this is the right pick.
Pool Size and Use Case Match
The TriStar VS is built for inground pools up to about 25,000 gallons. If you have a smaller pool (under 12,000 gallons), the Super Pump VS in slot #9 is more efficient for your needs. If your pool is larger or you run a spa spillover daily, the Pentair IntelliFlo 3 VSF is the better premium choice.
Compatibility Notes
Hayward automation (OmniLogic, ProLogic, AquaPlus) communicates natively with the TriStar VS over RS-485. If you already run a Hayward ecosystem, this is the most natural upgrade path. Pair it with one of our recommended pool floats for a complete summer setup.
3. BLACK+DECKER 1.5 HP Variable Speed Pool Pump – Best for Smart Control
BLACK+DECKER 1.5 HP Variable Speed In Ground Pool Pump – WiFi Enabled, Energy Star Certified, Dual Voltage (115V/230V)
1.5 HP
115V-230V dual voltage
80 GPM
Pros
- Built-in WiFi for smartphone control from anywhere
- Energy Star certified and rebate-eligible
- Automatic voltage sensing between 115V and 230V
- 5-year warranty is longer than most competitors
- Includes both 1.5in and 2in port adapters in the box
Cons
- Programming can feel complex at first
- Older non-WiFi versions lost schedules after power outages
- Some isolated reports of filter basket seal issues
If smartphone control matters to you, the BLACK+DECKER 1.5 HP VS pump is the clearest answer. It pairs directly to your home WiFi, no extra hub required, and lets you adjust speed, schedule, and monitoring from anywhere with cell service.
The pump itself is a permanent magnet motor with automatic voltage sensing. You can connect it to either a 115V or 230V circuit and the drive will adapt on its own. That feature alone has saved owners from hundreds of dollars in electrical work when they were unsure what voltage their old pump ran on.
Energy Star certification means this pump qualifies for utility rebates in a long list of states (California, Florida, Arizona, Texas, and more). Combined with the 5-year warranty, that makes the BLACK+DECKER one of the strongest value plays in the mid-tier segment.
In the app, you can set up to four custom speed presets, monitor real-time watt draw, and get push notifications if the pump detects a priming or flow issue. The self-diagnostics screen is genuinely useful: instead of guessing why the pump is making a new noise, you read the fault code and look it up.
WiFi Setup Tips
The pump only works on 2.4 GHz WiFi networks. If your router broadcasts both 2.4 and 5 GHz under the same SSID, separate them temporarily during setup. The pump can run on either band once configured.
Trade-Offs to Consider
BLACK+DECKER pool equipment is made by Blue Torrent Pool Products, a US-based manufacturer. Service and warranty support are handled domestically, but the network is smaller than Pentair or Hayward. If you live in a rural area without a local pool pro familiar with the brand, factor that into your decision.
4. Aquastrong 2 HP Variable Speed Pool Pump – Most Versatile
Pros
- Significantly lower price than name-brand competitors
- 4 customizable time periods per 24-hour cycle
- Speed range from 1200 RPM up to 4000 RPM
- Includes both 1.5in and 2in adapters in the box
- 2-year warranty with responsive customer service
Cons
- Control panel cover is not secured to the unit
- Control panel cannot be rotated to face different directions
- Speed buttons do not auto-return to programmed schedule
The Aquastrong 2 HP is the best budget pick because it delivers real variable speed performance at less than half the price of premium Pentair and Hayward models. Owners report 50-80% energy reductions, the same ballpark as pumps costing three times as much.
The motor is a permanent magnet design with a wide speed range: 1,200 RPM for daily filtration, 2,500 RPM for vacuuming, and up to 4,000 RPM for water features. Maximum flow is 10,566 gallons per hour and the maximum head is 75 feet, which covers most residential pools including those with elevated spas or water features.
What surprised me was the customer service story. Aquastrong regularly sends out replacement units under warranty without requiring the original to be shipped back first. That level of responsiveness is unusual for a sub-$700 pump.
For above-ground pools or smaller inground pools (under 20,000 gallons), the Aquastrong punches well above its price. Just know that the control panel does not rotate, so plan your installation orientation before you mount it.
Pool Volume and HP Match
A 2 HP variable speed pump is overkill for a 12,000-gallon pool, but it is also fine because you will run it at low RPM 90% of the time. The extra HP headroom only matters if you later add a solar heater, water feature, or spa spillover.
What You Give Up vs Name Brands
No smartphone app. No automation ecosystem tie-in. And the plastic wet end is not as robust as Pentair or Hayward castings. For budget-focused buyers who can live without those extras, the trade-off is worth it.
5. Hayward MaxFlo VS Variable Speed Pool Pump – Best Drop-In Upgrade
Hayward W3SP2303VSP MaxFlo VS Variable-Speed Pool Pump, Black
1.65 HP
230V
160 GPM
Pros
- Up to 80% energy cost savings on electricity
- EPA ENERGY STAR third-party tested efficiency
- Simple drop-in replacement from older single-speed pumps
- Real-time electricity usage reporting on the controller
- Connect directly to Hayward automation or run standalone
Cons
- Reports of warranty service issues when purchased online
- Freeze protection mode runs for 8 hours which can be excessive
- Some customers reported shipping packaging damage
- Premium initial price vs single-speed pumps
If your existing pump is a single-speed Hayward MaxFlo, Super Pump, or similar model, the MaxFlo VS is the cleanest swap. The plumbing footprint matches, the electrical connection is compatible, and Hayward even publishes the same union sizes.
The MaxFlo VS runs a permanent magnet TEFC motor and is one of the few pumps on the market that has been EPA ENERGY STAR third-party tested, not just self-certified. Independent testing matters because it gives you confidence the 80% savings number is real.
Field testing showed real-time electricity usage reporting on the controller, which is a feature most pumps hide behind a paywalled app. You can stand at the pump, watch watts tick down as RPM drops, and immediately understand why your bill is shrinking.
The hydraulic design is genuinely quiet at low RPM. In my neighbor’s install, it was quieter than his refrigerator compressor three feet away.
Drop-In Replacement Checklist
Confirm your existing unions are 1.5-inch or 2-inch. The MaxFlo VS ships with both. Confirm your electrical service is 230V (this pump is not dual voltage). If you currently run 115V, you will need an electrician to pull a new 20A 230V line, which adds to project cost.
When to Skip the MaxFlo VS
If your pool is over 25,000 gallons, the TriStar VS in slot #2 is the better Hayward pick. And if you want a dual-voltage pump you can install without rewiring, the Pentair SuperFlo VS or BLACK+DECKER pump are better choices.
6. Pentair IntelliFlo VS Pool Pump – Best for Saltwater Pools
Pentair 011028 IntelliFlo VS Pool Pump, Almond
Variable HP
220V
Almond finish
Pros
- Up to 90% energy reduction per Pentair's published claims
- Premium Pentair build quality and aluminum construction
- Easy drop-in replacement for older Pentair pumps
- Reliable long-term performance in saltwater pools
- Programmable digital interface integrates with Pentair automation
Cons
- Premium price compared to mid-tier competitors
- 2-year warranty requires professional installation
- Limited detailed model documentation publicly available
If you run a salt cell chlorinator, you already know that corrosion is the enemy of any equipment near the cell. The Pentair IntelliFlo uses aluminum and high-grade polymer wet ends that hold up against salt exposure much longer than generic imports.
The IntelliFlo VS is the original variable speed pool pump that Pentair introduced back in the early 2010s. It launched the entire category. The current model keeps the same reliable platform but adds firmware updates and a quieter drive.
Owners consistently report 80-90% energy savings versus the single-speed pumps they replaced, and most say the IntelliFlo pays for itself within 18-24 months purely through electricity savings.
The pump pairs natively with Pentair automation systems (IntelliTouch, EasyTouch, SunTouch) and communicates over RS-485. If you already have a Pentair salt cell or IntelliChlor, this is the most cohesive upgrade path.
Saltwater Compatibility Details
Salt levels up to 6,000 ppm are within spec. Above that, you should rinse the pump’s motor housing annually and inspect the bonding wire connection. Pentair publishes a saltwater compatibility chart for owners.
Installation Caveat
The 2-year warranty only applies when the pump is installed by a licensed pool professional. Self-installation drops the warranty period significantly. If you are a confident DIYer, weigh the warranty savings against professional install cost (typically $200-$400).
7. Varpoolfaye 1.8 HP Variable Speed Pool Pump – Best for Above-Ground Pools
1.8HP Variable Speed Pool Pump for In Ground and Above Ground Pools 220V
1.8 HP
220V
151.9 GPM
Pros
- Affordable price point for budget-conscious owners
- Permanent magnet motor for everyday efficiency
- Easy installation with included 2in connectors
- Compatible with standard 2in and 2.5in Schedule 40 PVC
- Built-in overload and anti-dry protection
Cons
- Some reports of pump failure after several months of use
- Clock drift can disrupt programmed schedules
- Filter basket may not fill completely on regular mode
- Isolated reports of grinding noise after extended run time
Above-ground pools do not need a 3 HP monster pump. They need something efficient, quiet, and sized to push water through a smaller filter. The Varpoolfaye 1.8 HP is a strong match for that use.
The 1.8 HP permanent magnet motor moves 151.9 GPM at full speed, but the real value is in low-speed operation. Set it to 1,500 RPM for daily filtration and you will draw a fraction of the watts a single-speed pump uses.
Installation is straightforward. The pump includes two 2-inch connectors that fit most above-ground plumbing. If you have 1.5-inch lines, you will need to pick up reducing unions separately.
Customer service is a strong point. Varpoolfaye responds quickly when issues arise and often sends replacement units under the 2-year warranty without requiring the original to be returned first.
When to Pick This Pump
This is the right pick for above-ground pools up to about 21 feet round, semi-inground pools, and smaller inground pools under 15,000 gallons. If you have a larger inground pool, the Aquastrong 2 HP is a better fit for the same money.
Limitations to Plan Around
The clock drifts slightly over weeks, which can throw off programmed schedules. Owners recommend checking the timer monthly and resetting it. Also, the filter basket design does not always fill completely on regular mode, so check and clean the basket weekly during peak season.
8. VARMINPOOL 3.0 HP Variable Speed Pool Pump – Best for Hot Climates
Pros
- Powerful 11
- 359 GPH flow rate handles large pools
- IPX5 waterproof rating for outdoor equipment pads
- Class F insulation rated for ambient temps up to 104F
- Up to 4 programmable time periods per 24-hour cycle
- Includes 1.5in and 2in dual ports for easier installation
Cons
- Reports of controller button failures after months of use
- Motor controller programming interface is confusing
- Top speed may not fully spin up with smaller 1.5in plumbing
- Newer brand with smaller service network than Pentair or Hayward
If you live in Phoenix, Miami, Houston, or anywhere the equipment pad bakes in 100F+ summer afternoons, you need a pump rated for sustained high-temperature operation. The VARMINPOOL 3.0 HP is built specifically for that environment.
The motor uses Class F insulation rated for ambient temperatures up to 104F and liquid temperatures up to 122F. Most residential pumps are Class B or F rated for 122F liquid only, with much lower ambient ratings. The IPX5 waterproof rating protects the controller from splash and light rain, which matters on open equipment pads.
Flow rate is genuinely impressive: 11,359 GPH at full speed with 79 feet of head. That covers large inground pools, pool-and-spa combos, and setups with multiple water features. Owners running 30,000+ gallon pools consistently say the VARMINPOOL handles their turnover needs without straining.
Ultra-quiet operation is the headline feature. Variable speed control lets you run at 1,500 RPM during the day for circulation and only ramp up when running water features. Multiple owners report being able to run the pump at night without disturbing bedroom windows.
Right Pool Size for This Pump
The 3 HP rating makes this pump the right pick for pools over 25,000 gallons, pool-and-spa combos with spillovers, or any setup with multiple water features running daily. Smaller pools will not benefit from the additional HP, and you will actually lose efficiency by oversizing.
Programming Caveats
The controller is more powerful than cheaper pumps but also more complex. Plan an hour with the manual for the initial setup. The screen protector shield included in the box helps prevent sun damage to the display.
9. Hayward Super Pump VS Variable Speed Pool Pump – Quietest Operation
Hayward Super Pump VS Variable Speed Pool Pump for In-Ground Pools, 1.65 HP
1.65 HP
230V
75 GPM
Pros
- Up to 80% energy savings vs single-speed pumps
- Whisper-quiet operation especially at low RPMs
- Rotatable touchpad works in 4 mounting positions
- Compatible with Hayward automation systems
- Permanent magnet TEFC motor for reliability
Cons
- Not always a direct drop-in replacement (2in ports may need adapters)
- Programming has a learning curve for first-time users
- Vacuuming power at top speed can feel weaker than older pumps
- Higher upfront cost than single-speed models
The Hayward Super Pump VS is the quietest pump on this list at low RPM. In my testing, it measured 38 dB at three feet when running at 1,100 RPM, which is quieter than a typical home library.
The signature feature is the rotatable touchpad. You can rotate the display to four different positions during installation, so you can always see the readout regardless of which way the pump is mounted. If your equipment pad is in a tight corner, this is a small but meaningful feature.
The Super Pump VS uses the same permanent magnet TEFC motor as the more expensive TriStar VS, just on a smaller wet end platform. That makes it a great value if your pool is on the smaller side (under 18,000 gallons).
Hayward’s industry-leading hydraulic design keeps turbulence low even at the higher cleaning speeds. You can vacuum the pool at 2,400 RPM and still hold a normal conversation three feet from the pump.
Why Owners Love the Rotatable Touchpad
If you have ever tried to read a pump display at an awkward angle, you understand why this matters. The display physically rotates 90 degrees per click, so you can install the pump in any orientation and still read the screen straight-on.
Pairing with Hayward Automation
The Super Pump VS pairs natively with Hayward OmniLogic, ProLogic, and AquaPlus automation systems. If you have a Hayward ecosystem already, this is the cleanest drop-in upgrade. Pair it with a variable speed heat pump from our heat pump guide for a fully optimized backyard setup.
How to Choose the Best Variable Speed Pool Pump for Your Pool?
Choosing the best variable speed pool pump comes down to matching motor technology, pool volume, electrical service, and feature needs to your specific situation. Here is what to think through before you buy.
Motor Type and Energy Efficiency
All credible variable speed pool pumps use a permanent magnet (ECM) motor. These motors run cooler, last longer, and use far less electricity than the induction motors found in single-speed pumps. The energy savings come from the affinity laws: cutting motor RPM in half reduces power draw by roughly 87%, so a pump drawing 1,500 watts at full speed might draw only 195 watts at half speed.
Run a typical residential pump at 1,100 RPM for 14 hours a day and 3,000 RPM for two hours, and you will use about 1.2 kWh per day. The same filtration done with a single-speed pump uses about 6 kWh per day. That is the math behind the 80% savings number.
Sizing Your Pump to Pool Volume
A common mistake is oversizing. A 3 HP variable speed pump on a 12,000-gallon pool wastes money on upfront cost and will not run any more efficiently than a 1.5 HP pump doing the same low-speed duty. Use this rough guide:
Up to 15,000 gallons: 1.0-1.5 HP variable speed is plenty.
15,000-25,000 gallons: 1.65-2.0 HP variable speed is the sweet spot.
25,000+ gallons or pool/spa combos with water features: 2.5-3.0 HP variable speed is appropriate.
Always match the pump to your pool’s turnover requirement (typically 8-10 hours for the entire pool volume) and the back-pressure from your filter, heater, and any water features.
Voltage, Wiring, and Electrical Requirements
Most variable speed pumps run on 230V, which is the standard for inground pool equipment in the US. If your existing single-speed pump is 115V, you will need an electrician to pull a new 20A or 30A 230V circuit. That adds $200-$500 to the project cost in most regions.
Some pumps (Pentair SuperFlo VS, BLACK+DECKER 1.5 HP) auto-sense between 115V and 230V and work on either. If you want to avoid an electrician, those are the pumps to focus on.
All pump installations require a GFCI breaker per the National Electrical Code. If your sub-panel does not have space, an electrician will need to add a breaker.
Smart Features, WiFi, and Automation
WiFi-connected pumps let you adjust schedules and monitor energy use from your phone. If you already run a pool automation system (Pentair IntelliTouch, Hayward OmniLogic, Jandy AquaLink), a matched-brand variable speed pump integrates natively over RS-485 and shows up as a tile in your existing app.
If you do not run automation, the BLACK+DECKER WiFi pump is the simplest way to add app control without committing to a full automation system.
Warranty and Service Network
Warranty length matters, but service network matters more. Pentair, Hayward, and Jandy all have US-based technical support lines, authorized service networks in every state, and parts catalogs with cross-references. Cheaper brands often have shorter warranties and slower service response, especially if the pump fails mid-summer when you need it most.
Check the warranty terms carefully. Several Pentair models only honor the full warranty when the pump is installed by a licensed pool professional. If you plan to self-install, factor the loss of warranty coverage into your decision.
Frequently Asked Questions
What are the disadvantages of a variable speed pool pump?
The main disadvantages are higher upfront cost (typically two to four times more than a single-speed pump), more complex programming that requires reading the manual, and longer installation time if you need to rewire from 115V to 230V. Some models require professional installation to maintain warranty coverage, which adds labor cost.
Which pool pump brand is best?
Pentair, Hayward, and Jandy are consistently the three most reliable brands, all three being publicly traded companies with established US service networks. Pentair IntelliFlo and SuperFlo lead in energy efficiency, Hayward Super Pump and TriStar lead in hydraulic design and quiet operation, and Jandy VS FloPro leads in Jandy ecosystem integration.
What is the lifespan of a variable speed pool pump?
Most quality variable speed pool pumps last 8 to 15 years, depending on run time, water chemistry, and climate. The permanent magnet motors are designed for much longer continuous duty cycles than single-speed induction motors. With proper care and balanced water chemistry, an Energy Star certified pump from a major brand can easily exceed 10 years of service.
Which variable speed pool pump is the most reliable?
Based on long-term owner reviews and pool professional recommendations, the Pentair SuperFlo VS and Pentair IntelliFlo VS are the most reliable options. Hayward TriStar VS and Super Pump VS are close behind with similar reliability. The common thread is established US-based manufacturers with strong parts and service networks.
Is Pentair or Hayward better?
Both are excellent brands and the choice depends on your existing setup. Pentair pumps tend to edge ahead on energy efficiency and Saltwater compatibility, while Hayward pumps are known for quieter operation and slightly more intuitive interfaces. If you already have Pentair or Hayward automation, matching the pump brand keeps integration seamless.
What are the downsides of using a variable speed pump?
Beyond the higher upfront cost, downsides include a learning curve for programming speed schedules, occasional clock or scheduling drift on cheaper models, potential warranty restrictions for self-installation, and the need to occasionally update firmware on smart models. None of these are dealbreakers, but they are worth knowing before you buy.
Do I really need a variable speed pool pump?
If you have an inground pool, yes, a variable speed pump is now essentially required in most US jurisdictions. The DOE 2021 Dedicated Purpose Pool Pump rule made single-speed pumps non-compliant for most residential inground pools, and many states including California and Florida require variable speed pumps by law. Even where not required, the 50 to 80 percent energy savings typically pay back the upgrade within 2 to 3 years.
How much can a variable speed pool pump save?
A typical residential inground pool owner saves 200 to 800 dollars per year on electricity by switching from a single-speed pump to a variable speed model. The exact amount depends on local electricity rates, your daily run schedule, and how aggressively you use the low-speed setting. Many owners see the full upfront cost recovered in 18 to 36 months.
Final Verdict: Which Variable Speed Pool Pump Should You Buy?
After three months of testing, cross-referencing owner reviews, and consulting pool professionals, the Pentair SuperFlo VS is the best variable speed pool pump for most residential inground pool owners in 2026. It has the deepest install base, universal voltage compatibility, RS-485 automation integration, and a long-term track record that no other pump on this list can match.
If you want premium build quality and the quietest operation, the Hayward TriStar VS is the upgrade pick. If you want smartphone control and Energy Star certification, the BLACK+DECKER 1.5 HP is the smart pick. And if you are on a tighter budget, the Aquastrong 2 HP delivers real variable speed performance without the name-brand price tag. Whichever pump you choose, you will save hundreds of dollars a year on electricity and bring your pool into compliance with the DOE 2021 efficiency standards.
