Introduction
An efficient filtration system is essential to keep your swimming pool water free of any organic contamination. However, there are different types of pool filters: sand, cartridge, and diatomaceous earth (DE); which one is a better answer? Selecting the appropriate pool filter removes dirt, debris, and algae from the pool, ensuring its cleanliness and safety. But when used with a robot pool cleaner, you can decrease maintenance time & ensure better cleaning. In this article, we will cover the best types of pool filters, as well as why the combination of a robot pool cleaner and the right filter is the ultimate secret to owning a sparkling clean pool.
Types of Pool Filters
The three basic types of pool filters each have their unique advantages and disadvantages:
Sand Filters
Sand filters are the most common type of pool filter used because they are easy to set up and cheap. These filters send pool water through a bed of silica sand and trap debris. The sand particles trap dirt and debris so that only clean water is returned to the pool.
✅ Pros:
Low Maintenance (need to backwash)
Cost-effective
Suitable for bigger pools with heavy debris loads
❌ Cons:
Filters only down to 20–40 microns (less effective for the fine particles)
We need to backwash where water is wasted . Each of the filters above has multiple disadvantages that can lead to health-related issues.
Every 5–7 years, and has to be replaced
👉 Ideal for: Large pools with substantial debris and low maintenance needs
Cartridge Filters
Cartridge filters employ a pleated-type polyester cartridge to trap dirt and debris. They filter more finely than sand filters and use less water when being cleaned.
✅ Pros:
10–15 micron filter (captures smaller particles)
Energy efficient due to lesser pump pressure required
Easier to clean — remove the cartridge and hose it down
❌ Cons:
Requiring cartridge replacement every 2–3 years
Usually, don’t get clogged with more considerable debris than sand filters
It is not so efficient for huge debris loads
👉 Best for: Residential pools with moderate debris and finer filtration requirements
Diatomaceous Earth (DE) filters
DE filters have a powder that is fossilized diatoms that form an excellent filtration layer. The filtration level is the highest compared to all other types of filters.
✅ Pros:
Filters as low as 2–5 microns (grabs even the tiniest particulates)
Yields the purest water quality
Best for picking up fine dirt, algae, and debris
❌ Cons:
Costlier Than Sand and Cartridge Filters
DE filters require to be backwashed regularly and recharged with DE powder.
DE powder is problematic if inhaled
👉 Ideal for: Pools with algae issues and high water clarity standards
This is why a robot pool cleaner improves the filtration
Although a quality pool filter is typically the primary means of removing minute particles and pollutants, a robot pool cleaner puts the finishing touch on your pool cleaning efforts. In contrast to suction and pressure-side cleaners, robotic pool cleaners work independently from the pool’s filtration system, lightening the load on the filter and increasing its longevity.
Top Advantages of a Robot Pool Cleaner:
✅ Independent Operation – A robot pool cleaner is an independent machine since it has its own motor and filtration system so that it does not depend on the pool’s pump or filter.
✅ Smart Navigation – Most swimming pool robot cleaners use innovative mapping technology that covers every inch of the swimming pool (walls and steps).
✅ Debris Removal – Some are designed to capture delicate, large, and fine debris, like the Maytronics pool cleaner or the Beatbot AquaSense 2 Pro.
✅ Energy Efficiency– Robotic cleaners consume less energy than pressure-side cleanerashing equipment with a booster pump.
✅ Algae & Dirt Removal – Robotic cleaners scrub surfaces of your pool, assisting in both removal and prevention of algae buildup
Best Robot Pool Cleaners: Beatbot models
For more intensive cleaning, you can consider a high-quality robot pool cleaner from Beatbot:
✅ iSkim Ultra – Best for surface clean up and skimming debris before reaching the pool’s bottom.
✅ Beatbot AquaSense 2 Pro – For deep cleaning, wall climbing, fine or large debris
✅ Beatbot AquaSense 2 – A cost-effective, multifunctional solution for thorough pool cleaning with powerful suction and intelligent navigation.
They are compatible with all kinds of pool filters and will help increase the overall cleaning efficiency while reducing maintenance time.
The Best Filter for Your Pool – How to Choose the Right One
The best kind of pool filter will vary depending on the size of your pool, how much you use it, and your maintenance/preference people:
✅ For big pools with high debris volume:
For heavy debris, a sand filter with a robot pool cleaner, such as the Beatbot AquaSense 2 Pro, is perfect.
✅ For residential-type pools with moderate debris:
Filter cartridges and the pool vacuum robot provide finer filtration and easier Maintenance.
✅ If you have a pool with persistent algae or excellent debris:
A Diatomaceous Earth (DE) filter and a wall climbing pool cleaner like a Beatbot AquaSense 2 Pro provide the best filtration and maximum depth cleaning.
1 Common Pool Filter and Cleaner Maintenance Tips
Now that you have what you need to keep your pool filter and robot pool cleaner operating correctly, here are some maintenance tips:
Clean Your Filter Regularly
Sand filters – Backwash every 2–4 weeks.
Cartridge filters — Hoses them out every 2–4 weeks and replace cartridges as necessary.
DE filters – Backwash and add fresh DE powder every 4-6 weeks.
Make sure to clean the internal filter basket after every use.
Monitor the cleaner’s brush heads and tracks regularly and replace them if they’ve become worn.
Balance Pool Water Chemistry
Maintain pH, chlorine, and alkalinity levels to avoid scale buildup and algae formation.
Use a Skimmer and Pool Vacuum
A skimmer takes floating debris before it can settle.
।। A vacuum cleaner for pool handles of heavy debris and fast spot cleaning.
So the pool is fantastic, but now what do we do?
You can drain an inground pool without a pump. Use a siphon hose or a submersible pump to drain the pool manually.
How to acid wash a pool: Acid washing removes stains and scales but should be used sparingly to avoid damaging the surface.
Poole robot to pick up algae? Yes, features like those on the Maytronics pool cleaner and the Beatbot AquaSense 2 Pro are built to aid in algae from the pool surfaces.
The Reasons Why You Need Beatbot
Robot pool cleaners take the load off your pool’s filtration system, enhance overall cleaning efficiency, and prolong the life of your filter.
