RollBot - Smart Automatic Roller Rod for Aquarium Filters
The RollBot is a plug-and-play automatic roller rod designed to seamlessly upgrade any aquarium roller filter. Unlike traditional systems that rely on float switches, the RollBot uses time-based intervals to roll up filter paper, ensuring consistent water filtration.
With a simple button interface, users can set their preferred daily roll distance (100mm to 2000mm) and manually advance the filter with quick clicks. The RollBot also features a continuous mode and reversible rolling direction for ultimate flexibility.
Upgrade your aquarium’s filtration system with the RollBot – effortless, reliable, and customizable.
