The Zymurgoes Tune-Up Kit is a purpose-built replacement parts bundle for the Maytronics Dolphin Nautilus CC Plus robotic pool cleaner. This kit targets owners who want to restore their cleaner's peak performance without the hassle of sourcing individual parts. It is an excellent choice for maintaining a clean pool without professional help.
Standout features include both fine and ultra-fine filter cartridges, allowing the cleaner to trap everything from leaves and twigs to fine sand and dust. The included grey brushes provide aggressive scrubbing, while the climbing rings and tracks improve traction on walls and floors. Together, these parts significantly enhance debris collection and overall cleaning coverage.
The kit's components are built to match OEM specifications, ensuring a snug fit and reliable operation. The white color is standard and unobtrusive.

A potential drawback is the limited compatibility: this kit only works with the Dolphin Nautilus CC Plus model. Additionally, while it covers the most common wear items, it does not include seals or internal parts that may also need replacement over time. Since no consumer reviews are available yet, long-term durability remains unverified.
Overall, the Zymurgoes Tune-Up Kit offers a convenient and cost-effective solution for maintaining a Dolphin Nautilus CC Plus.

- Easy top-load filter access simplifies debris removal and maintenance.
- Quick plug-and-play setup with no complex installation required.
- Suitable for a wide range of pool shapes and sizes up to 33 ft.

The Dolphin Nautilus CC is a robotic pool cleaner designed to take the hassle out of pool maintenance. 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. 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.
Pros
- High-efficiency microfiltration captures fine dirt, sand, and leaves for pristine pool water.
- Works with a wide range of popular Dolphin robot models, reducing the need for multiple filter types.
- Easy to clean and maintain with no special tools required.
- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons
- Not compatible with Dolphin Nautilus CC Pro or CC Supreme models, limiting its use for newer variants.
- Older versions of Active 10 or S50 may require removal of a plastic piece for proper fit, which could be inconvenient for some users.
- As an aftermarket part, it may not perfectly match OEM quality or warranty coverage.
The Ulticor Ultra Fine Filter Basket is an aftermarket replacement designed specifically for a wide array of Dolphin robotic pool cleaners. It is an ideal choice for pool owners who already own compatible models such as the Dolphin S50, S100, Active 10/15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, and others. This basket is not intended for the Nautilus CC Pro or Supreme versions, so buyers should verify compatibility before purchasing.
What sets this filter apart is its microfiltration technology, which captures even the tiniest debris particles. In real-world use, this translates to a noticeably cleaner pool with clearer water, as fine dirt, sand, and pollen are effectively trapped. The basket is easy to rinse and clean every four to six weeks, maintaining peak performance without hassle. Users report that it fits snugly and works reliably cycle after cycle.
The design is straightforward: a white, lightweight plastic basket measuring roughly 9x5x7 inches. Build quality feels solid for an aftermarket part, though it may not have the exact finish of an OEM component. The inclusion of installation tips for older Active 10 or S50 units (which may need a small internal plastic piece removed) shows attention to compatibility details. A video guide is available upon request to assist with that adjustment.
Potential drawbacks are mostly centered on fitment limitations. Owners of Nautilus CC Pro or Supreme will need to look elsewhere. Also, the need to modify older robots could be a minor inconvenience for those not comfortable with simple DIY tasks. However, for the vast majority of compatible users, installation is plug-and-play.
Overall, the Ulticor Ultra Fine Filter Basket offers excellent value for money. It delivers superior filtration at a lower price than official replacements, while covering a wide range of popular Dolphin models. If you own one of the listed robots and want to keep your pool sparkling clean without breaking the bank, this filter is a smart buy.

Build quality reflects Dolphin's legacy of over 40 years in pool care. The caddy is built to protect each component of your robot, helping to extend its lifespan. It is compatible with all residential robotic pool cleaners, so you can use it with a Dolphin or another brand.
One possible drawback is the price, which may feel steep for a storage accessory. Additionally, its 24 by 18 by 12 inch frame takes up some space, so measure your storage area before purchasing.
Overall, the Dolphin Universal Caddy is a smart investment for any robotic pool owner who values tidiness and durability. It delivers on its promises and keeps your robot ready for action all year round.
Brand: Dolphin
Model: Universal Caddy
Color: Multicolor
Dimensions: 24 x 18 x 12 inches
Weight: 13.23 pounds
Compatibility: All residential robotic pool cleaners
Assembly Time: 15 minutes or less
Pros
- Cordless operation eliminates tangled cords and manual hose setup
- Wall and waterline scrubbing reduces hand-scrubbing effort
- Long 150-minute runtime covers large inground pools in one cycle
- Top-load filter basket simplifies debris removal and cleaning
- Auto-docking and quick-drain make retrieval convenient
Cons
- No remote control or app scheduling, so operation is limited to one-button mode selection
- At 26 pounds, the unit is still fairly heavy to lift out of the pool despite the quick-drain design
- Customer feedback is limited at this time, so long-term reliability is not yet independently verified
The EZIOOV U8 is a cordless robotic pool cleaner built for owners of medium to large inground pools up to 2,600 square feet. It is designed for anyone who wants automated cleaning of the floor, walls, and waterline without dragging hoses or spending weekends brushing. With a 150-minute runtime, the U8 can handle weekly maintenance in a single charging cycle.
The standout feature is wall and waterline scrubbing. Triple brushless motors and strong traction allow the robot to climb surfaces and remove grime, oil, and stuck-on debris that usually requires hand work. Gyroscope and ultrasonic sensors help it follow efficient paths and avoid obstacles while covering deep ends, corners, and ladder areas.
The 26-pound body feels solid in the pool, and the quick-drain design makes lifting easier after the cycle ends. Its 4-liter top-load filter catches fine dirt, sand, leaves, and larger debris, and you can empty the basket without turning the unit over. The carbon black finish looks clean, and a simple one-button control keeps the experience straightforward.
The main limitations are the lack of remote control or app scheduling and the unit's weight when removed from a deep pool. You choose a mode by pressing the button and let the robot do its work, but there is no way to steer it manually. Since this model has limited customer feedback available, long-term durability is not yet verified by extensive real-world use.
For pool owners who prioritize cordless freedom, wall scrubbing, and a long runtime, the EZIOOV U8 is a strong option. It simplifies routine maintenance and eliminates the tangles and setup of corded units. If you have a larger inground pool and prefer one-button automation, the U8 is worth serious consideration.
