Automatic Pool Cleaner Buying Guide: Robotic vs Suction vs Pressure

Types of Automatic Pool Cleaners

1. Robotic Pool Cleaners (Premium Choice)

Self-contained units with their own filtration system and power source. They operate independently from your pool's circulation system.

How They Work:

• Plug into standard electrical outlet (low voltage)
• Navigate pool using sensors and programming
• Have built-in filtration bags or cartridges
• Scrub surfaces with rotating brushes

Pros:

• Best cleaning performance - Scrub and vacuum simultaneously
• Energy efficient - Use 80-90% less energy than suction cleaners
• No impact on filtration - Don't use pool pump or filter
• Advanced features - Smart navigation, remote control, programmable
• Climb walls - Clean waterline and some can clean steps

Cons:

• Higher upfront cost - $800-$3,000+
• Requires removal - Take out after each cleaning cycle
• Electronics can fail - More complex than mechanical cleaners
• Cord management - Need to handle power cord

2. Suction Pool Cleaners (Most Popular)

Connect to your skimmer or dedicated suction line and use your pool pump's suction power to move and collect debris.

How They Work:

• Connect to skimmer or suction port
• Use pool pump suction for movement and pickup
• Debris goes into pump basket or pool filter
• Move in random patterns following suction force

Pros:

• Affordable - $150-$500 range
• Simple operation - Plug and play, few moving parts
• Reliable - Mechanical operation is very dependable
• No electricity needed - Powered by existing pool pump
• Good for light debris - Excellent for leaves and small particles

Cons:

• Uses pool circulation - Reduces skimmer effectiveness
• Increases filter load - More frequent filter cleaning needed
• Pool-only cleaning - Most don't climb walls effectively
• Random cleaning - May miss spots or over-clean others
• Pump dependency - Only works when pump is running

3. Pressure Pool Cleaners

Use water pressure from your pool's return line to move around and collect debris in an attached bag.

How They Work:

• Connect to return jet or dedicated pressure line
• Use pressurized water for propulsion
• Collect debris in attached collection bag
• Some models include booster pump for extra power

Pros:

• Don't load filter - Debris collected in separate bag
• Good for large debris - Excellent for leaves and acorns
• Wall climbing - Most models clean walls and waterline
• Reliable operation - Simple mechanical design
• Don't reduce skimming - Leave skimmer free for surface cleaning

Cons:

• May need booster pump - Additional equipment and energy cost
• Bag maintenance - Regular emptying and cleaning required
• Installation complexity - May require plumbing modifications
• Higher operating cost - Especially with booster pump
• Limited fine filtration - Better for larger debris
