Keeping a commercial pool clean isn’t just about aesthetics—it’s about safety, compliance, and guest satisfaction. At M&M Pool & Spa Services, we specialize in pool cleaning and maintenance across Miami-Dade and South Florida, and we’ve created this comprehensive resource to give you the step-by-step knowledge to maintain your commercial pool like a pro.

Why Regular Commercial Pool Cleaning Is Essential

Unlike residential pools, commercial pools receive higher usage, which introduces more contaminants, body oils, sunscreens, and debris. Regular pool maintenance ensures:

• Water safety and sanitation
• Compliance with local health codes
• Preventing costly equipment damage
• Improved guest experience and satisfaction

Step-by-Step: How to Clean a Commercial Pool

1. Pool Debris Removal

The first step in maintaining a commercial pool is removing surface and submerged debris. High foot traffic in public pools brings in leaves, plastics, and other floating items, especially in outdoor pools.

Debris removal tips:

• Use a heavy-duty leaf skimmer to remove floating leaves and debris daily
• Check the skimmer baskets and pump strainer daily for blockage or buildup
• Consider installing an automated pool surface skimmer for high-traffic pools

2. Brushing Steps and Walls

Next, tackle algae, grime, and calcium build-up by brushing down the pool shell, steps, and walls thoroughly.

Brushing steps include:

• Use a commercial-grade pool brush compatible with your pool’s surface (plaster, fiberglass, or vinyl)
• Focus on corners, steps, tile lines, and shaded areas where algae thrive
• Brush multiple times per week, depending on usage

3. Vacuuming Procedure

Once brushing has loosened dirt and algae, the next phase is vacuuming. Vacuuming keeps the pool floor clean and prevents the spread of contaminants.

Vacuuming procedure for commercial pools:

• Manual vacuuming: Attach a vacuum head to a telescopic pole and hose attached to the pool’s filtration system
• Automatic vacuums: Robotic vacuums can be programmed to clean overnight and reduce maintenance labor
• Vacuum the pool slowly in overlapping lines to ensure no dirt is left behind

4. Water Balancing and Chemical Testing

Testing and adjusting the pool’s chemical levels are just as important as physical cleaning. This ensures water is safe, and equipment remains corrosion-free.

Commercial pools should maintain these levels:

• Chlorine: 1.0 – 3.0 ppm (public pools may require higher minimums)
• pH: 7.2 – 7.6
• Calcium Hardness: 200 – 400 ppm
• Total Alkalinity: 80 – 120 ppm

Test the water at least once daily, or more frequently in high-use areas or during heat waves common in South Florida.

5. Filter System Maintenance

Your filter system is the heart of your pool sanitation. Depending on whether you have a sand, cartridge, or DE (diatomaceous earth) filter, maintenance frequency will vary.

General filter maintenance includes:

• Backwashing sand and DE filters weekly or as needed
• Cleaning cartridge filters every 2–4 weeks
• Inspecting for clogs or restricted flow regularly

South Florida Focus: Commercial Pool Cleaning in the Miami-Dade Climate

Miami-Dade and the greater South Florida region present unique challenges when maintaining commercial pools. The subtropical climate, high seasonal rainfall, and year-round usage mean more consistent care is needed.

Why cleaning commercial pools in South Florida requires special attention:

• Frequent storms introduce debris and shift water chemistry
• Humidity and warmth accelerate algae growth and bacterial contamination
• Tourist attractions, resorts, and HOAs experience high bather loads year-round

This is why many commercial facilities in Miami and South Florida partner with professionals like M&M Pool & Spa Services for regular maintenance tailored to local climate demands.

Hiring a Professional Pool Maintenance Service

While daily maintenance can be handled in-house with the right training, commercial pools often require professional oversight for compliance and advanced equipment care.
