Note: Never use a stainless steel brush on vinyl or fiberglass surfaces, as it can cause deep scratches and damage.
2. Automatic Pool Cleaners – Hands-Free Efficiency
For those looking to reduce manual labor, automatic pool cleaners are a top-tier solution. These devices come in various models, each with unique advantages.
Types of Automatic Pool Bottom Cleaners
- Suction-Side Cleaners: These attach to the pool’s skimmer and use the pump’s suction to move around and collect debris. Ideal for lighter cleaning tasks.
- Pressure-Side Cleaners: Powered by a separate booster pump, these are great at picking up larger debris and are excellent for frequent use.
- Robotic Pool Cleaners: These are self-contained units with their own motors, filters, and brushes. They are energy-efficient and capable of scrubbing even the most stubborn surfaces with precision.
Robotic models like the Dolphin Nautilus, Hayward TigerShark, or the Zodiac MX8 are highly acclaimed for their effectiveness on pool bottoms and walls.
3. Pool Vacuums – Complementing Brushing Efforts
While some vacuums are manual and attach to the pool’s filtration system, others are robotic and can be used for both vacuuming and scrubbing. While not as effective as brushes for algae removal, they help to suck up debris after you’ve scrubbed the bottom of the pool.
Key Tip: Always brush the floor before vacuuming to loosen dirt and debris—this makes the vacuuming process much more effective.
Picking the Right Tool Based on Pool Type
The type of pool surface you have will influence the appropriate cleaning tool you should use. Using the wrong brush or cleaner can lead to surface damage, which is costly and unnecessary.
Concrete (Plaster) Pools
Concrete or plaster pools are durable and can handle abrasive brushes. For effective cleaning:
- Use a stiff-bristled brush or stainless steel brush to tackle algae and calcium deposits.
- Robotic or pressure-side cleaners can also be safely used on this surface type.
Vinyl Liner Pools
Vinyl pools are more delicate and susceptible to tears or scratches:
- Opt for a soft-bristled brush to avoid damaging the liner.
- Most robotic cleaners are suitable, but ensure the unit comes with soft crawling tracks to prevent liner abrasion.

Best Practices for Scrubbing Your Pool Bottom
Getting the best results requires more than just having the right tools—it also depends on your cleaning strategy.
Brushing Techniques for Maximum Effectiveness
Whether you choose to brush manually or opt for a robotic cleaner, technique matters:
- Start with pool chemistry balanced: Before scrubbing, test your water’s pH, alkalinity, and chlorine levels. Balanced water helps loosen algae and makes scrubbing easier.
- Use the correct brush head and pole length: Ensure that the brush is the appropriate type for your pool and the pole can comfortably reach the deepest part of the pool.
- Scrub in overlapping strokes: Move the brush in a sweeping or figure-eight motion to ensure full coverage and dislodge any stubborn buildup.
- Focus on high-debris areas: Pay attention to corners, under ladders, and near return jets where debris tends to accumulate.
Vacuuming After Scrubbing
As previously mentioned, vacuuming should always follow brushing. Here’s how to optimize your vacuuming:
- Set the filter to the “waste” setting if your vacuum is connected to the filter system; this prevents dirty water from cycling back.
- Move the vacuum slowly across the bottom to allow it to pick up loosened dirt.
- Empty the pump basket and filter after vacuuming to maintain efficiency.
How Often to Scrub the Pool Bottom
The frequency depends on several factors, including:
- How often the pool is used
- Surrounding environment (trees, dirt, etc.)
- Water chemistry balance
As a general rule:
- Daily: Skim debris and check water levels.
- Weekly: Brush the entire pool, including the bottom and walls.
- Monthly: Perform a deep clean using stain remover or acid washing if necessary.
Chemicals That Aid in Bottom Cleaning
While physical tools do most of the work, certain chemicals enhance the effectiveness of your cleaning routine.
Pool Shocking
Regular pool shocking—even before scrubbing—can weaken algae and bacteria, making them easier to remove. Calcium hypochlorite or granular shock is especially effective.
Algaecides
Algaecides act as a preventive measure, especially after scrubbing. They reduce the risk of algae regrowth and are particularly useful in green or black algae-prone pools.
Stain Removers
For stubborn stains or mineral deposits on the bottom, use a targeted stain remover. Products like Jack’s Magic The Pink Stuff (for metals) or The Blue Stuff (for organics) work wonders.
Acid Washing
Only for severe cases and best done by professionals, acid washing involves draining the pool and using diluted muriatic acid to remove deep-set stains and scale. While effective, it’s harsh and should be used sparingly.
Choosing the Right Cleaning Tool for Your Situation
With so many cleaning options on the market, making the right choice can feel overwhelming. Consider the following factors when deciding:
Pool Size and Shape
Larger or irregularly shaped pools benefit from robotic cleaners that cover more ground efficiently. Smaller or geometric pools may be adequately cleaned manually.

Can I use a regular household brush to scrub my pool bottom?
While a regular household brush may appear suitable at first glance, it is not recommended for scrubbing the bottom of your pool. Household brushes are often too abrasive or not suited to underwater use, which can lead to damage on pool surfaces such as vinyl, fiberglass, or tiled finishes. Pool brushes are specially designed with bristles that are both firm enough to dislodge algae and gentle enough to protect your pool lining. They also feature built-in connectors to attach to standard pool poles for easy use.
Additionally, pool brushes are made with materials that can withstand chlorinated water and other pool chemicals over time, whereas regular brushes may degrade quickly when exposed to these substances. Using the proper tools ensures your cleaning effort is effective without compromising the integrity of your pool structure. If purchasing a dedicated brush is not an option, it’s best to invest in one tailored to your specific pool type rather than risk damage from inappropriate alternatives.
How often should I scrub the bottom of my pool?
The frequency with which you should scrub the bottom of your pool depends on various factors, including how often the pool is used, your local climate, and the presence of nearby trees or vegetation. For most residential pools, scrubbing the bottom once a week is sufficient to maintain cleanliness and prevent algae buildup. In areas with high temperatures or during peak swimming season, you might need to do this twice a week to manage faster accumulation of algae and debris.
Consistent brushing is also important if you’re shocked your pool or treating it for algae, as scrubbing helps dislodge spores and allows the chemicals to work more effectively. If your pool is not used frequently and is well-maintained mechanically, you could reduce the scrubbing frequency. However, never skip brushing entirely. It’s an essential part of proper pool maintenance that enhances water circulation and helps your filter and chemicals perform better over time.
Is it necessary to use chemicals when scrubbing the bottom of the pool?
Yes, using pool chemicals, especially algaecides or chlorine, in combination with scrubbing is essential for effective cleaning and sanitation. Algae and bacteria can adhere to pool surfaces, forming a layer that brushing alone may not completely remove. Applying a suitable algaecide or using a chlorine-based shock treatment before scrubbing helps break down these organisms, making the scrubbing process more efficient and reducing the chance of regrowth.
After brushing, it’s also a good idea to run your filter and check the chemical balance of the water to make sure contaminants are removed. Some pool owners prefer using brushes that are designed to dispense cleaning chemicals while scrubbing for an added cleaning boost. This method is especially useful for pools prone to stubborn stains or algae. Always follow the manufacturer’s guidelines when applying chemicals and ensure the water pH and chlorine levels remain within the recommended range.
What’s the best way to scrub a vinyl-lined pool bottom?
Scrubbing a vinyl-lined pool requires special care due to the delicate nature of the material. The best method involves using a brush with soft nylon bristles to avoid tearing or scratching the vinyl surface. Begin by balancing the pool water chemistry to prevent any added stress to the liner and reduce the likelihood of staining. Light brushing in circular motions helps dislodge dirt and algae without damaging the material. Pay close attention around shadows and under ladders where algae can commonly collect.
In addition to manual brushing, consider using a suction-side automatic pool vacuum designed for vinyl-lined pools. These units gently clean the bottom without causing undue friction or wear. If algae buildup is significant, it’s wise to follow up with a shock treatment to eliminate spores and prevent future growth. After scrubbing, vacuum the loosened debris and run your filter to help clear the water. Regular maintenance and the use of the proper tools will extend the life of your vinyl liner and maintain a clean, clear pool.
How can I prevent algae from coming back after scrubbing?
After scrubbing, the best way to prevent algae regrowth is to maintain proper water chemistry, including balanced chlorine levels, pH, alkalinity, and calcium hardness. Ensuring that your chlorine level stays between 1–3 ppm inhibits algae growth, while a stable pH (7.4–7.6) allows chlorine to work more efficiently. Additionally, using a preventive algaecide on a weekly basis, especially during warm weather or heavy pool usage, can significantly reduce the chance of algae returning.
It’s also important to run your pool filter for several hours a day to circulate the water and remove any suspended algae particles dislodged during scrubbing. Cleaning or backwashing your filter regularly ensures it continues to operate at peak performance. Keeping your pool covered when not in use helps reduce leaves, dirt, and spores from entering the water. Combined with consistent brushing and proper chemical use, these strategies help you maintain a sparkling clean pool and reduce long-term maintenance challenges associated with algae and bacterial growth.
Can I use a pressure washer to scrub the bottom of my pool?
Using a pressure washer on your pool’s bottom is generally not recommended unless specifically designed for pool cleaning, as the high pressure can damage certain pool surfaces. Vinyl and fiberglass pools, for instance, are especially vulnerable to scratches and tears from excessive water pressure. However, if you have a concrete pool and use a pressure washer that’s intended for pool cleaning or in its lowest-pressure setting, you might consider it for removing stubborn stains or heavy buildup.
If you decide to use a pressure washer, always perform a test in a small, inconspicuous area first to ensure it does not harm the surface. It’s also important to keep the nozzle at a safe distance during use and move it in a consistent motion to avoid concentrated pressure on one spot. For regular maintenance, it’s safer to stick with a soft brush and chemical treatment, which are less likely to cause harm and are sufficient for keeping your pool clean. Always consult your pool manufacturer or a pool professional before using any high-pressure cleaning tool on your pool.
