4. Pentair Kreepy Krauly Inground Pool Cleaner: Best Value Suction-Side

🛒  Check Price on Amazon →

The Pentair Kreepy Krauly is a classic suction-side cleaner that has been on the market for years. We researched its design and found that the diaphragm valve creates a random cleaning pattern that covers the pool floor and walls. Based on owner feedback, it is a workhorse that requires little maintenance. However, because its movement is random, it may not clean as systematically as robotic models, and it can get stuck on stairs or obstacles.

This cleaner is an excellent value for pool owners who want a simple, low-cost solution. It is not ideal for those who want a fast, thorough clean or have pools with many obstacles. If you prioritize coverage efficiency, consider a robotic or pressure-side cleaner instead.

• Diaphragm valve technology provides random cleaning pattern for full coverage.
• Durable construction with few moving parts for low maintenance.
• Connects to standard skimmer or dedicated suction line.

Pros: Very affordable and reliable.; Simple design with minimal parts to replace.
Cons: Random pattern may miss spots occasionally.

5. Polaris 280 Pressure-Side Pool Cleaner: Best Pressure-Side

🛒  Check Price on Amazon →

The Polaris 280 is a well-known pressure-side cleaner that many owners trust for heavy debris. We compared its performance to other pressure-side models and found it excels at picking up leaves and twigs. It uses a separate debris bag, which keeps the pool filter clean. However, it requires a booster pump to operate, which may not be present on all pools. Owner feedback mentions that the bag can need frequent emptying and the unit may occasionally need adjustments to prevent flipping.

This cleaner is best for pools with heavy leaf debris and an existing booster pump. It is not suitable for pools without a booster pump or for those who prefer a quieter operation. Skip this if you want a self-contained unit that doesn’t require additional equipment.

• Uses water pressure to move and collect debris in a separate bag.
• Sweep hose helps push debris toward the cleaner.
• Effective on large debris like leaves and acorns.

Pros: Excellent at collecting large debris.; Does not rely on pool filter.
Cons: Requires a booster pump, adding installation cost.

6. Aquabot Breeze 4WD Robotic Pool Cleaner: Best for Flat Pools

🛒  Check Price on Amazon →

The Aquabot Breeze 4WD is a budget-friendly robotic cleaner that focuses on floor cleaning. We researched its features and found that the 4-wheel drive gives it good mobility on flat surfaces. Owner reviews highlight its ease of use and effective cleaning on pool floors. However, it cannot climb walls or clean the waterline, which limits its coverage. Some users also reported that it can get stuck on pool drains or steps.

This cleaner is suitable for pool owners with flat, simple inground pools who primarily need floor cleaning. It is not ideal for those with wall algae or waterline scum, as it will not address those areas. If you need a comprehensive clean, consider a model that also handles walls.

• 4-wheel drive provides excellent traction on flat surfaces.
• Dual scrubbing brushes agitate dirt and debris.
• Easy-to-clean filter cartridge with quick-release handle.

Pros: Good for flat-bottom pools.; Affordable robotic option.

The Hayward AquaNaut 400 is a pressure-side cleaner specifically engineered for vinyl liner pools. We evaluated its design and found that it uses a unique steering system to move randomly without harsh impacts. Owner feedback indicates it is gentle on liners and picks up debris well. However, like other pressure-side cleaners, it requires a booster pump, which adds to the overall cost. Some users noted that it can sometimes climb too high and get stuck on the top step.

This cleaner is a good match for vinyl pool owners who have a booster pump and want to protect their liner. It is not recommended for pools without a booster pump or for those with very fine debris, as the bag may not capture small particles. If you have a concrete or fiberglass pool, other models may be more suitable.

• Designed for gentle cleaning on vinyl liner pools.
• Unique steering system provides random but thorough coverage.
• Large debris bag reduces emptying frequency.

Pros: Gentle on vinyl liners.; Effective on medium to large debris.

Frequently Asked Questions

What is the difference between suction-side, pressure-side, and robotic pool cleaners?

Suction-side cleaners connect to your pool’s skimmer or dedicated suction line and use the pump’s suction to move and collect debris, which is then trapped in the pool filter. Pressure-side cleaners use a booster pump to create water pressure that propels the cleaner and collects debris in an attached bag, bypassing the pool filter. Robotic cleaners are self-contained units with their own motor and filtration system, operating independently of the pool’s circulation system. They are generally more efficient but cost more upfront.

Do I need a booster pump for a pressure-side pool cleaner?

Most pressure-side pool cleaners require a booster pump to generate sufficient water pressure for proper operation. Some pools come pre-plumbed for a booster pump, but if yours does not, you will need to have one installed. Check the manufacturer’s specifications before purchasing.

How often should I run my automatic pool cleaner?

For optimal cleanliness, it is recommended to run your automatic pool cleaner daily or at least every other day during peak swimming season. The duration depends on the size of your pool and the amount of debris. Robotic cleaners often have programmable timers, while suction and pressure-side cleaners run as long as the pump is on.

Can automatic pool cleaners climb walls and clean the waterline?

Many robotic and some suction-side cleaners are designed to climb walls and clean the waterline. However, not all models offer this capability. Check the product specifications: ‘cleans walls’ and ‘waterline cleaning’ are key features to look for if you need full coverage. Pressure-side cleaners typically climb walls but may not clean the waterline as effectively.

How do I maintain my automatic pool cleaner?

Regular maintenance includes emptying the filter bag or cartridge after each use, checking for debris tangled in wheels or hoses, inspecting the diaphragm or turbine for wear, and storing the cleaner properly when not in use. For robotic cleaners, clean the filter and rinse the unit. For suction and pressure-side cleaners, ensure hoses are not cracked and the booster pump (if applicable) is functioning.
