Product Comparison Shortcode
Pros
- Captures fine particles, including hair, sand, oils, and lotions, for noticeably clearer water.
- Large 3.5L capacity reduces the need to empty mid-session.
- Easy to clean with a hose, thanks to separable dual filters and top access.
- Genuine Beatbot construction ensures durability and exact compatibility.
- Built-in Hall sensor delivers automatic basket recognition for added convenience.
Cons
- Priced at a premium level for a replacement basket, so it may seem expensive compared to generic alternatives.
- Only fits Beatbot AquaSense Pro, AquaSense 2 Pro, and AquaSense 2 Ultra, so it will not work with other pool cleaner brands or older models.
The Beatbot Genuine Dual Filter Basket is a replacement component built for AquaSense Pro, AquaSense 2 Pro, and AquaSense 2 Ultra cordless robotic pool cleaners. It is an ideal purchase for current owners who want a reliable, OEM-quality filter that keeps pool water clean without constant maintenance.
The twin-layer setup combines an inner coarse filter with an outer fine 150μm mesh, so it handles large leaves and stones as easily as hair, sand, and even oils and lotions. The 3.5L capacity is a standout feature, allowing the robot to finish a full cleaning run before the basket needs attention.
Maintenance is clearly a priority. The basket can be pulled out through the top, split into two sections, emptied, and rinsed with a garden hose. The built-in Hall sensor adds convenience by automatically detecting the basket when it is installed, so the robot knows it is ready to operate.
Build quality is in line with Beatbot's OEM standards, using high-toughness polyester that resists stress cracking. The main drawback is the premium price and the fact that the basket only fits a specific family of Beatbot cordless cleaners, so it is not a universal part.
For owners of the compatible AquaSense models, this genuine filter basket is a dependable choice that restores performance and simplifies pool care. Given its fine filtration, generous capacity, and easy cleaning process, it is a worthwhile investment for maintaining crystal-clear water all season.

This filter basket is ideal for pool owners who want to maintain peak filtration performance in their Beatbot cleaner without resorting to third-party parts.
Its standout feature is the dual-layer filtration system with a 150μm mesh that captures debris of all sizes, from leaves and stones to fine particles like sand and hair.

One potential drawback is its limited compatibility; it only works with a few Beatbot models, so owners of other robotic cleaners cannot use it. Additionally, if you already own an AquaSense 2 Ultra or compatible model, note that this filter basket is included in the original packaging, making this purchase only necessary as a replacement or spare.
Overall, the Beatbot Genuine Dual Filter Basket delivers excellent filtration performance and easy upkeep for compatible pool cleaners. Its robust build and thoughtful design make it a worthwhile investment for maintaining crystal-clear water, despite the higher price point and limited compatibility.

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.

- 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.
Buying Guide: Choosing the Best Beatbot Ultra Fine Filter
1. Compatibility with Your Robot Model
Before purchasing, confirm the filter fits your specific Beatbot AquaSense model. The (2025 NEW) Beatbot Genuine Dual Filter Basket is designed for the AquaSense 2 Pro and AquaSense Pro (and also fits the AquaSense 2 Ultra), while the (2025 New) Beatbot Genuine Dual Filter Basket is exclusively for the AquaSense 2 Ultra. Using the wrong version may cause poor fitment and reduced filtration. If you are using a Dolphin robotic cleaner, the Fiitzn ultra fine filter offers broad compatibility with many models. Check our Beatbot AquaSense Pro filter basket guide for a detailed fitment list.
2. Filtration Efficiency and Mesh Size
The core of any filter is its ability to capture particles. Both genuine Beatbot baskets feature a dual-layer design with a 150μm mesh that traps ultra tiny debris like sand, hair, and even oils and lotions. The Fiitzn ultra fine filter uses a thick pleated fabric that grabs sand and leaves effectively, though it lacks the dual-layer system. For the finest filtration, the Beatbot baskets are superior. Learn more about filter types in our Beatbot AquSense replacement filter basket article.
3. Capacity and Maintenance Ease
A larger filter capacity means less frequent emptying. Both Beatbot baskets offer a generous 3.5L capacity, allowing thorough cleaning sessions. The top access design makes removal and rinsing straightforward: just separate the coarse and fine filters, pour out debris, and hose them clean. The Fiitzn filter also cleans easily with a garden hose and should be rinsed every four to six weeks. For tips on maintenance, see our Beatbot AquSense replacement filter pick.
4. Build Quality and Durability
Both Beatbot filters are crafted from high-quality polyester with stress cracking resistance, ensuring long life even in harsh pool conditions. They also feature a built in Hall sensor for automatic recognition upon installation. The Fiitzn filter uses an ABS plastic frame and sturdy pleated fabric that holds its shape under water flow. While not as premium as the OEM options, it provides solid performance for Dolphin users. For further insights, browse our replacement filters category.

Frequently Asked Questionsh2>
How often should I replace the Beatbot ultra fine filter?
With regular use, the filter should be replaced every three to six months depending on debris load. Rinse it after each cleaning cycle and check for wear; replace sooner if the fabric tears or the basket no longer seals properly. For more details, see our beatbot AquaSense filter basket.
Can I use a third party filter in my Beatbot AquaSense robot?
While third party filters like the Fiitzn are available, they are designed for Dolphin cleaners and do not fit Beatbot models. We recommend sticking with genuine Beatbot filters to ensure proper fitment and optimal filtration. Using an incompatible filter may cause debris to bypass the basket or damage the robot.
What is the difference between the two Beatbot genuine dual filter baskets?
Both baskets share the same 3.5L capacity and 150μm dual layer mesh, but one is specifically marked for AquaSense 2 Pro and AquaSense Pro models (ASIN B0FD9VTX9K), while the other is for AquaSense 2 Ultra only (ASIN B0FD9T491D). The Ultra version may have slight internal differences to accommodate that robot’s design.
Does the Beatbot ultra fine filter capture oils and lotions?
Yes, the genuine Beatbot dual filter baskets are effective at capturing oils and lotions from swimmers, thanks to the fine 150μm mesh. Regular cleaning will prevent these substances from building up and clogging the filter.
