Owning an above-ground pool is a great source of enjoyment and allows for quality time with loved ones. But they are durable as long as they are maintained.
Above-ground pools often get dirty when a big storm arrives or after heavy use. The debris buildup, if not removed promptly, can impact the overall health of the pool.
Finding no time for consistent maintenance? Let the era of robots take the plunge and use an automatic pool cleaner. This guide answers the question of how to keep an above-ground pool clean for safe swimming.

Why Above-Ground Pool Maintenance is Important
Above-ground pools with vinyl liners require much of the same effort as in-ground pools. They are, in fact, more prone to the settled debris and strains from the harmful contaminants. A single change in the pool’s chemistry can disturb the water’s health.

Following the maintenance checklist will prevent algae from breeding, damage to equipment, and cloudiness or discoloration of the water. These are the common nightmares of every pool owner.
A safe and inviting pool is achievable by cleaning the above-ground pool regularly. Keep its smaller filtration system clog-free. Improve the circulation, skim the surface debris, and check for any leaks or damage.
One reason why owners fret about the above-ground maintenance is the time-consuming cleaning. Self-propelled above-ground pool cleaners will help you reduce the time and effort since they can clean the pool in your absence.
A Step-by-Step Guide for Above-Ground Pool Maintenance
Even if the above-ground pool takes less time than in-ground ones, they still need a consistent routine and a little attention to stay durable. Here are the steps to follow:
Step 1. Test and Balance Water Chemistry
The first line of defense is to balance the water chemistry within the normal ranges. You can do this by testing the water through kits or strips. Test these:
- pH between 7.2 and 7.6
- alkalinity between 80-120 ppm
- Chlorine levels (Free Available Chlorine) between 1-3 ppm
- calcium levels between 200-400 ppm
Testing two times a week would alert you to any potential risks before they become noticeable. Hence, adjust the levels accordingly. You can add baking soda for alkalinity or chlorine tablets for sanitation when needed.
Step 2. Skim and Remove Debris Regularly
Mind these hazards that could damage the pool surfaces: nearby trees with falling leaves, activity around the pool, nesting insects under the rail, and mowing too close to the wall. Unfortunately, the surface debris can clog the filters and increase the chances of algae growth.
Skimming is the solution. You can do it manually with a net, but it would be a slow burn. If so, look for a robotic skimmer for stress-free surface cleaning. The Dreame J1 Skimmer uses solar power and smart path planning to clean the debris from every corner on its own.
Step 3. Clean the Pool Floor and Walls

More than the pool water, keep the floors, walls, and edges clean. The dirt and algae settle easily there, especially in vinyl-lined pools. Skim, vacuum, and brush all the surfaces. Protect the walls from cracks and rails from rusting.
Using a leaf net removes the debris, but vacuuming cleans the sunken dirt. You can either manually brush the pools or go for automated cleaners. A good robotic cleaner with 8,000 GPH suction power like that of the Dreame Z1 Pro, has an edge over other cleaners. It operates on preset cycles and features climbing wall elements.
Step 4. Run and Maintain the Filter System
Let the larger pump run for 12-16 hours/day or the smaller pump run 24 hours during peak seasons. You should still run the filter 8-12 hours daily, even if you don’t plan to use the pool for a day.
Both the pump and the filter work together to circulate the water so the entire pool volume is filtered. The water is pumped into the filter through impulsion, where it gets cleaned of any dirt or debris. The pump also catches the escaped debris from the skimmer.
To clean the filters, turn off the pump and remove the cartridge. Dip and clean the cartridge in the solution to remove oils and scales. Or, Backwash if sand or DE filters. Replace the filter media if worn out.
Keeping the pump and filter clean is essential to avoid an algae bloom. The better idea is to use the robotic cleaners to keep the debris out of the filtration system. Otherwise, the filers would have dirt stains over time.
Step 5. Shock the Pool Periodically

Shocking treatment refers to adding a high dose of chlorine to kill off harmful contaminants (such as bacteria, algae, combined chlorine, or chloramines).
There are two types of shock: Chlorine-based (sanitizers) and Non-chlorine shocks (oxidizers). Which one is best for you depends on your pool size, usage, and dosage requirements. The aim is to increase the levels of free available chlorine (FAC) so that it can perform sanitization effectively.
Shocking every week or after heavy use is also important to have an odour-free, hygienic pool. Most people would typically be shocked when the pool turns green or cloudy. It really gets rid of the stubborn algae or hidden germs.
Be sure to read the instructions, wear the safety gear, and shock at night. Leave the pump running and abstain from swimming till the chemistry is balanced out.
Common Above-Ground Pool Maintenance Mistakes to Avoid

By avoiding the following mistakes, you can keep your above-ground pool in good working condition.
- Neglecting water tests: Not doing monthly water tests will only lead to more troubles. Either buy a reliable kit or bring a water sample to a professional pool service for thorough checking.
- Not cleaning the Impeller: Many times, the impeller (part of the pump) goes unnoticed, leading to clogging issues or even stopping water flow.
- Draining completely: Another common mistake to avoid is draining the pool completely. Always leave the water in the pool (at least 6 inches) to protect the liner and structure.
- Overdosing: The more chemical impact creates a harsher swimming environment. It can also damage the pool surface and equipment.
- Ignoring hidden buildup: The microscopic particles can hide anywhere and wouldn’t show up until the damage has been done. Use clarifiers, algaecides, and sanitizers to remove the buildup.
Consistent cleaning can save you from liner damage or debris buildup. If you forget the maintenance schedule, use robotic pool cleaners for above-ground pools. Let the Dreame Z1 and J1 clean the pool for everyone to enjoy.
Seasonal and Long-Term Care Tips
So, how to keep the water clean off-season? Adapt these simple care tips for year-round protection.
In the summer, when the temperature rises, increase the filter run time. Use skimmers and cleaners frequently to remove debris.
When the summer ends, winterize the pool carefully. Store the chemicals, shut down the motor and pump, and store them properly. But don’t drain the above-ground pool fully, otherwise it will collapse inward. Cover the pool with a closing kit, an air pillow, or a cover pump.
Clean the pool each time you open or close it. Balance the water out and run the automatic cleaner to remove the winter debris. If possible, ask for the professional cleaning service.
Conclusion
Taking proper care of the pool on a monthly basis will save the pool from expensive damage. The above tips will ensure you are doing the maintenance tasks correctly. For pool owners with busy schedules, buy yourself a hassle-free Dreame robotic cleaner and skimmer. Store the supplies in a dry place during the off-season.
Keep the above-ground pool crystal-clear and ready to swim in all seasons!
