Emptying the filter is the one chore a robot can't do for you — so Maytronics made it a five-second job. The MaxBin™ is a single top-loading basket, 50-100% larger than the twin cartridges it replaced. Lift the lid, pull the handle, tip it out. There's nothing to disassemble and, on most days, nothing to rinse.
Every robot below is built around a MaxBin™: the Max-Series™ Cayman and Escape, and the ProLine™ Quantum with its XXL basket and included NanoFilters™. If you hate cleaning filters, or your pool takes on heavy leaves, start here.

One basket, one handle, one motion. Here's why it changed the way a Dolphin is cleaned.
The Max-Series™ is defined by the MaxBin™, a second-generation update to the standard Dolphin filter. The twin smaller cartridges have been replaced by one massive top-loading debris bin.
According to the engineers who designed it, the MaxBin™ came straight from owner feedback. Earlier models like the Nautilus CC Plus used two small filters and six parts, each of which had to be pulled apart to clean. Now there is nothing to disassemble: the new design cuts cleaning time by about 80% and reduces the touch points from six to one.
Cleaning a Max-Series™ robot takes seconds and one hand. Lift the top panel and a handle pops up; turn the bin over and the debris falls out. If there's fine silt, a quick spray with the hose clears it.
Compare that with the previous generation, where you opened two cartridges and handled six parts, each of which usually needed hosing off. A single trap door and a grab handle replaced all of it.
The MaxBin™ is the result of years of refinement to the Dolphin line, and it anchors the Dolphin Max-Series™. It carries forward everything that worked in earlier robots and fixes the part owners liked least.
More capacity means more leaves, grit and debris per cycle before the bin needs emptying — and a full-flow design that keeps suction strong as it fills. With its state-of-the-art filtration, the Dolphin Max-Series™ delivers crystal-clear water while capturing even fine debris.
The Dolphin Max-Series™ is the product of continuous improvement, and the MaxBin™ is the clearest example: bigger where it counts, simpler where it matters, and built to make the least-loved part of pool robot ownership disappear.
For the first time, MaxBin™ capacity meets NanoFilter™ precision. The pleated NanoFilter™ panels stop fine particles from recirculating, and they're the only filter that traps oils: as oil is captured it forms a clear coating around the trapped debris, which rinses away when you clean the bin. The result is exceptionally clear, refined water.

The difference is clear. With the Dolphin Max-Series™, Maytronics raised the bar for its 2026 robotic pool cleaners. The easy-to-clean, high-capacity MaxBin™ with NanoFilters™ leaves the old cartridge design behind — built for leaves and debris, and the reason so many owners now insist on MaxBin™ technology.
Learn More About Max-Series™
MaxBin is an oversized debris collection system featured on select Dolphin robotic pool cleaners. The MaxBin offers a larger filtration capacity compared to standard filter cartridges, allowing the robot to collect more debris before needing to be emptied.
MaxBin is available on select Dolphin Max-Series robots. These models are specifically designed to take advantage of the larger bin capacity for pools with heavier debris loads. Browse the Max-Series lineup to see which models include MaxBin.
MaxBin holds significantly more debris than a standard filter cartridge, meaning fewer interruptions during cleaning cycles. While standard cartridges work well for lighter debris, MaxBin is ideal for pools that accumulate leaves, dirt, and other larger debris on a regular basis.
Cleaning the MaxBin is simple. After each cleaning cycle, remove the bin from the robot, empty the collected debris, and rinse it with a garden hose. For best performance, allow the MaxBin to dry completely before reinstalling. Regular cleaning helps maintain optimal suction and filtration.
If your pool regularly collects leaves, dirt, or other heavy debris, MaxBin is absolutely worth it. The larger capacity means less frequent emptying and more thorough cleaning cycles. For pools surrounded by trees or in windy areas, a Max-Series robot with MaxBin can save you significant time and effort.
