- Crystal clear water without excessive filtration or extra pump time
- Saves money on chemicals and electricity by improving system efficiency
- Works around the clock for continuous water treatment
- Great value with 20x concentration for many treatments per bottle

The ADIOS! 20X Pool Cleaner and Liquid Enzyme Clarifier is a specialized treatment designed to tackle cloudy water caused by organic contaminants such as body oils, sunscreen, soap scum, and other bio-matter. Unlike traditional clarifiers, this enzyme-based formula works continuously to break down these particles, making it an excellent choice for above-ground pool owners who often struggle with smaller filtration systems.
One of the standout features is its bioactive formula that targets stubborn organic waste that chlorine and other sanitizers struggle to remove. By doing so, it not only clarifies the water but also improves the efficiency of your existing chemical system, potentially reducing the amount of chlorine or bromine needed. Users appreciate that it works 24/7 in the background without requiring additional filtration cycles.
The product's design is straightforward: a 32 oz bottle with a concentrated 20x formula. Just 1 oz treats 5,000 gallons, offering up to 20 treatments for typical above-ground pools. This concentration translates to great value and minimal storage space. The liquid is easy to pour and mixes quickly with pool water.
Potential drawbacks include the lack of verified customer reviews, as this product is new to the market. Additionally, while it is effective against organic cloudiness, it may not address issues caused by algae blooms or high mineral content. Regular application is recommended for best results, and users should ensure proper pH and sanitizer levels for optimal performance.
Overall, the ADIOS! 20X Pool Cleaner is a promising solution for pool owners seeking a natural, enzyme-based approach to water clarity. Its ability to save on chemicals and extend filter life makes it a cost-effective addition to pool maintenance routines. If you have an above-ground pool or a small filtration system, this product is worth considering.
Pros

- High suction (5000 GPH) and fine filtration effectively remove both large and small debris.
- Smart navigation with zigzag pattern ensures efficient coverage of all pool surfaces.
- Long runtime (120 minutes) covers large pools in a single charge.
- Easy retrieval with auto-park feature and user-friendly app control.
Cons

The BOTLUXE Pool Robot Vacuum is a cordless robotic cleaner designed for both inground and above ground pools, aiming to simplify pool maintenance. With a 5000 GPH suction power and a 4-liter filter basket, it targets leaves, sand, dirt, and fine debris, making it suitable for pool owners who want an automated cleaning solution without the hassle of hoses or manual scrubbing.
Standout features include its smart zigzag navigation, which systematically covers floors, walls, and waterline to minimize missed spots. The 120-minute runtime can handle pools up to 1,830 square feet on a single charge, and the 2.5-hour fast charging ensures it is ready for the next cycle quickly. The auto-park function is convenient, bringing the vacuum to the pool edge when the cycle ends or battery is low.
Design-wise, the BOTLUXE is built with durable tracks that can climb slopes up to 30 degrees, providing access to most pool surfaces. The cordless design eliminates tangled hoses, and the app allows you to preset cleaning modes, suction levels, and run times from land, then simply drop the vacuum in. The 150-micron fine filter basket captures both large and small particles, reducing the frequency of emptying.
Potential drawbacks include the lack of user reviews, making it difficult to gauge long-term reliability and real-world performance. The app control may not appeal to those who prefer simple physical buttons, and the 30-degree slope limit might not handle steeper pool walls or complex shapes. Additionally, the vacuum is currently only available in blue, which may not match all pool aesthetics.
Overall, the BOTLUXE Pool Robot Vacuum offers a compelling set of features for its price point, especially for pool owners seeking a cordless, app-controlled cleaner with strong suction and good coverage. However, given the absence of customer feedback, it is advisable to consider the 1-year warranty as a safety net. If you value convenience and automation, this could be a solid choice, but waiting for more reviews might provide extra confidence.
Pros
- Fast and easy application with minimal scrubbing
- Works on a wide variety of pool surfaces
- Acid-free formula is gentle on delicate materials
- Effectively removes oily residues and sunscreen
- Comes with a Magic Sponge for convenience
Cons
- Does not remove calcium or hard water buildup

The STAR BRITE Home Pool Waterline Cleaner Scum Remover is a fast-acting, acid-free spray designed to tackle dirt, scum, and oily residues along pool waterlines, steps, and shelves. It is ideal for pool owners who want a non-abrasive cleaner that works on multiple surfaces such as tile, vinyl, plaster, fiberglass, and plastic.
Its standout feature is the quick 30-second soak time: simply spray the affected area, let it sit, then wipe clean with a scrub pad or the included Magic Sponge. This makes pool maintenance less labor-intensive, especially for removing sunscreen buildup and oily scum that standard cleaners struggle with.
The formula is acid-free, which means it is safe for delicate surfaces but will not remove calcium deposits or hard water stains. For those issues, an acid-based cleaner is recommended. The product is also not intended for painted or ink printed surfaces, such as printed vinyl liners or decals, so always test in an inconspicuous area first.
Build quality is solid with a 32 oz spray bottle that delivers adequate coverage for most residential pools. The instructions are clear, and the included sponge adds value. However, the limitation on printed surfaces and the inability to handle hard water buildup are honest drawbacks to consider.
Overall, the STAR BRITE Waterline Cleaner is a reliable choice for routine scum removal on compatible surfaces. It offers convenience and effective results for pool owners who need a gentle yet powerful cleaner, as long as they are aware of its restrictions.

It is best suited for owners of above-ground or in-ground pools up to 33 feet in length who want a set-it-and-forget-it solution. With its wall-climbing ability and active scrubbing brush, this unit promises a thorough clean without manual effort.
Standout features include the top-load filter basket, which makes emptying debris quick and mess-free.

Real-world performance is strong on walls and floors, though heavy debris may require more frequent filter cleaning.
Design-wise, the Nautilus CC is compact and lightweight at under 15 pounds, making it easy to lift in and out of the pool. The blue/black color scheme is standard, and the build quality feels durable. Dolphin has a legacy of reliability, and this model continues that tradition with robust materials and a simple interface.
One potential drawback is that the filter basket, while convenient, can fill up quickly in pools with lots of leaves or sand, requiring attention mid-cycle. Also, the price is higher than entry-level cleaners, but the added wall scrubbing and filter ease justify the cost for many users.
Overall, the Dolphin Nautilus CC is an excellent choice for pool owners who value convenience and effective cleaning. It delivers on its promises with minimal fuss, making it a worthwhile investment for maintaining a sparkling pool. If your pool fits within the size limit and you want to reduce manual work, this cleaner is highly recommended.
Buying Guide: What to Look for in a Plaster Pool Cleaner
Surface Compatibility
Plaster is softer than concrete or gunite. A cleaner that uses stiff bristles or metal parts can scrape the surface over time. Look for robotic vacuums with soft rubber brushes or gentle scrubbers. For manual cleaning, natural pumice stones are safe on plaster when used with light pressure. Avoid abrasive pads or acid-based cleaners unless they are specifically labeled for plaster.
Type of Cleaner: Robotic, Manual, or Chemical
Robotic pool cleaners like the Dolphin Nautilus CC or the BOTLUXE model handle floors, walls, and waterline in one cycle. They are ideal for busy owners who want set-and-forget cleaning. Manual tools like pumice stones and scrapers let you target specific stains, such as calcium rings at the waterline. Chemical clarifiers and enzyme treatments break down oils and fine particles that filters miss. A combination of robotic cleaning and weekly enzyme dosing often works best for plaster pools.
Ease of Use and Maintenance
You want a cleaner that is simple to set up and empty. Top-load filter baskets and cordless designs save time. For robotic models, look for long runtime and auto-park features so you do not have to fish for the unit. Manual tools should attach to standard pool poles and float for easy retrieval. Consider how often you will need to empty the filter or replace pumice stones.
Targeted Stain and Scum Removal
Plaster pools often develop calcium deposits and waterline scum from sunscreen and body oils. A dedicated waterline cleaner like the STAR BRITE formula can remove oily residues without damaging plaster. For calcium buildup, a pumice stone such as the Pool Blok PB-12 works well. Enzyme clarifiers like ADIOS! 20X break down organic matter that leads to cloudy water and filter clogs. If your pool has a deep end, see our best robotic cleaner for deep inground pool recommendations for models that handle depth well.
Final Thoughts
For most plaster pool owners, a smart robotic vacuum like the Dolphin Nautilus CC Automatic Robotic Pool Vacuum delivers thorough, gentle cleaning with minimal effort, while a targeted manual tool such as the Pumie 1-Pack Pumice Stone for Pool Tile Cleaning handles stubborn calcium spots without harsh chemicals. Pair these with an enzyme clarifier like ADIOS! 20X for weekly maintenance, and your plaster pool will stay clear and smooth all season. For larger pools, also consider the best inground pool cleaner for 3000 sq ft pool to ensure full coverage.

Frequently Asked Questions
Can I use a robotic pool cleaner on a plaster pool?
Yes, as long as the robot has soft brushes or rubber scrubbers. Models like the Dolphin Nautilus CC and BOTLUXE are designed for all pool surfaces, including plaster. Avoid robots with stiff nylon bristles that can wear down the finish over time.
What is the best way to remove calcium deposits from plaster?
A natural pumice stone like the Pool Blok PB-12 is safe for plaster when used with light pressure. It floats, so you can scrub underwater without draining. For thick deposits, scrape first with a pool scraper, then finish with the pumice stone. Avoid acid-based cleaners that can etch plaster.
How often should I use an enzyme clarifier in my plaster pool?
For best results in 2026, add a weekly dose of enzyme clarifier like ADIOS! 20X or Bio Ouster 4-in-1. This keeps water clear by breaking down body oils, sunscreen, and other organics that cause cloudiness and scum. It also helps your filter run more efficiently.
Will a waterline cleaner damage my plaster pool?
Most waterline cleaners are safe on plaster if they are acid-free. The STAR BRITE Home Pool Waterline Cleaner is designed for tile, vinyl, plaster, and fiberglass. Always test a small hidden area first and avoid using on printed or painted surfaces. For persistent scum, combine with a pumice stone scrub.
