The Dolphin MaxBin is a larger and innovative Gen-2 filter from Maytronics' Dolphin brand. Apart of the Dolphin Max-Series, this filter bin is super easy to clean and a gamechanger in pool robot filtration. So the Dolphin MaxBin – will this massive gen-2 filter disrupt the market?
The Best Filter Yet?
This massively sized and easy to clean bin is a part of the Dolphin MaxSeries, and is one of my favorite robot filters I have tested, thanks to its ease of use and cleaning performance. So let’s dive in to the problem and how it was solved.

Gen-2 MaxBin vs. Gen-1 Filters
First Generation Dolphin robots have 2 separate filters that when disassembled will create 6 separate parts. To clean the robot, you’re disassemblign and then reassembling those 6 parts. There’s no way around it. It’s not particularly hard to do, but it does take some time. The Dolphin filtration system was dramatically improved on Gen 2 robots with MaxBin.
If you’re looking for MaxBin, they are included with the following robots, each with a different price point:
- The Dolphin Quantum
- The Dolphin Cayman
- The Dolphin Escape
If you’re thinking MaxBin is just slightly larger than gen 1 filters, you’re in for a suprirse. Dolphin Engineers made MaxBin a whopping 50-225% larger than the gen 1 standard cartridge filters. There are two major advantage.

One, the cleaning process is now a breeze. There is now 0 disassembly required to clean the filters. With a clever dropdown on the basket, it’s one click design reduces cleaning to just rinse and repeat Everyone that goes from Gen 1 to Gen 2 raves about how easy it is to clean.
Easy to Clean
But just how easy is this filter to clean? Super easy. Unlike the cartridges, you don’t have to disassemble the filter to clean it. Simply, unlatch the robot and the handle pops right up on the maxBin. Simply grab the handle, take it out, rinse it, and slide it back in.

Compare that to fiddling with all the parts of the Dolphin gen 1 cartridges, We have moved to a single filter that can be cleaned with 0 disaassembly. MaxBin’s grab and go design simplifies the process to open and rinse. It’s that easy.
Dolphin Quantum's MaxBin with NanoFilters
The Dolphin Quantum has the XXL MaxBin, which is the largest capacity of the bunch with over 400 square inches of storage capacity, it is Dolphin’s largest filtration system ever.
NanoFilters are a must-have for any pool after testing all of the best robotic pool cleaners of 2025.
With included Nanofilters, Quantum cleans deeper than the standard filters found on gen 1 robots. Nanofiltration captures what the standard filters miss and makes a huge difference iwhen it comes to clearing cloudy pool water. It delivers a level of water clarity and polish you won’t find with standard filters.
Dolphin Cayman and Dolphin Escape
The last two robots with included MaxBins are the Dolphin Cayman and Dolphin Escape. With a MaxBin of 260in2, the filter is over 50% larger than the standard cartridge filters. Super easy-to-clean, these baskets deliver a new cleaning performance - especially at this price range.
NanoFilter Add-On
This NanoFilters is an optional add on for the Cayman and Escape, and I would recommend adding one to your cart If you’re going this direction. a I personally would not have a pool robot without these Nanofilters. The Dolphin Cayman and Dolphin Escape with Nanofiltration upgrade is one of the hiddens secrets in the Dolphin lineup. You get all the benefits of MaxBin and Nanofiltration, at a significant savings.
Final Verdict
Overall, the gen 2 MaxBin is a big step up and improves user experience by a wide margin. AIf you’re looking for the easiest pool robot to clean, The Dolphin Max-Series that includes the MaxBin is definitely the way to go. – Finally, don’t forget to make sure your robot package includes the Nanofilters.
