The RoboPure Cordless Robotic Pool Cleaner is a practical choice for pool owners seeking an affordable, automated way to keep flat pool floors clean. It targets above ground and inground pools with flat bottoms, offering a simple one-button start that eliminates manual vacuuming and tangled cords.
Standout features include a 120-minute runtime, which is sufficient for most typical pool sizes on a single charge. Its powerful suction handles everyday debris like dust, sand, small leaves, and hair, maintaining a tidy pool floor between deeper cleanings. The cordless design adds flexibility, letting you drop it in and walk away.
Design-wise, the cleaner is lightweight and easy to lift, with a removable filter tray that simplifies emptying. The self-parking function is a thoughtful touch, automatically moving toward the pool wall when the battery runs low or the cycle ends, making retrieval convenient. Build quality feels adequate for its price point, though materials are basic.
However, this model has clear limitations. It works only on flat floors, ignoring walls, steps, and sloped sections. Battery life may degrade over time, and the device can struggle with larger leaves or heavy accumulations. It also lacks advanced navigation, meaning it cleans randomly rather than systematically, which may leave some areas untouched.
Verdict: The RoboPure Cordless Robotic Pool Cleaner is a solid entry-level option for those with straightforward flat pools who prioritize convenience and low cost. It delivers reliable daily maintenance, but for complex pool shapes or heavy debris, consider a more advanced model with wall-climbing and stronger suction.
Pros
- Energy-efficient suction-side operation, no additional electricity or booster pump required
- Advanced cyclonic suction and X-Drive navigation deliver comprehensive floor and wall cleaning
- Compatible with variable-speed pumps and lower flow rates, ideal for modern pool systems
- Easy to install and calibrate with the included hose and connection accessories
Cons
- Requires careful flow calibration to achieve optimal cleaning performance and wall climbing
- Depends on your pool pump being operational, so it cannot clean when the pump is off
- The 32-foot hose may need an extension for very large pools
The Zodiac MX6 is a suction-side in-ground pool cleaner designed for pool owners who want effective, energy-efficient cleaning without a separate booster pump or robotic system. It connects directly to your existing skimmer or a dedicated suction line, making it a practical choice for most in-ground pools.
At the heart of the MX6 is the cyclonic turbine, which generates strong downforce to lift dirt and debris from the pool floor and walls.

The cleaner features X-Trax treads for excellent grip and maneuverability, while its compact and lightweight build makes it easy to remove, store, and handle. The included 32-foot Twist Lock Hose and connection accessories ensure a straightforward setup process.
One consideration is that the MX6 relies on your pool pump for operation, so it will not clean when the pump is off. It also requires careful flow calibration to achieve optimal wall-climbing and coverage, especially with variable-speed pumps. Very large pools may need additional hose length.
Overall, the Zodiac MX6 offers strong suction-side performance in a durable, efficient package. It is an excellent choice for pool owners with variable-speed pumps who want reliable floor and wall cleaning without extra energy costs or complex installation.

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.

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. The plug-and-play system means you can start cleaning in minutes: just plug it in, drop it in the water, and let it run for about two hours. 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
Wall Climbing Ability
For inground pools with sloped walls or deep ends, a cleaner that can climb is essential. Look for models with dedicated climbing turbines or tracked drive systems. The Zodiac MX6 uses a cyclonic turbine to create downforce and X-Trax for grip, while robotic options like the Dolphin Nautilus CC actively scrub walls with a rotating brush. Without this feature, debris on walls will remain untouched.
Navigation and Anti-Stuck Design
Pools with steps, lights, and drains require a cleaner that maneuvers around obstacles. Suction-side models with wheel deflectors (like the VINGLI) glide over drains, while robotic cleaners with smart navigation (like the Pondee X5) follow systematic patterns to avoid dead spots. Anti-stuck features prevent downtime and ensure thorough coverage. For more on smart navigation, see our Best Above Ground Pool Cleaners with App Control article.
Power Source and Setup
Suction-side cleaners connect to your pool’s skimmer or suction line, requiring no extra electricity but depending on your pump’s flow rate. Robotic models are self-contained with rechargeable batteries—cordless options like the RoboPure offer freedom from tangles, while corded robots like the Dolphin provide constant power. Consider your pool’s proximity to outlets and your willingness to manage hoses. Cordless models are ideal for quick daily maintenance, while suction-side units run continuously with your pump.
Filtration System
Non-flat pools often accumulate debris in corners and on steps. A fine-mesh filter or large-capacity basket reduces the frequency of emptying. Robotic cleaners with top-load filter baskets (like the Dolphin Nautilus CC) make cleaning easy. Suction-side models send debris to your pool’s main filter, which may require more frequent backwashing. If you have fine silt or leaves, a dual-stage filtration system (as seen in the AQUVII K2) captures both large and small particles effectively.
Final Thoughts
Choosing the right pool cleaner for your inground pool with uneven surfaces comes down to your priorities: if you want a reliable, energy-efficient suction-side unit that leverages your existing pump, the Zodiac MX6 Suction-Side In-Ground Pool Cleaner delivers proven wall-climbing performance. For a fully autonomous robotic solution that scrubs walls and filters debris into an easy-access basket, the Dolphin Nautilus CC Automatic Robotic Pool Vacuum is a premium choice that minimizes manual effort. Both models are built to handle the challenges of non-flat pool surfaces, so you can spend more time swimming and less time cleaning.
