The RoboSnail is an automated glass cleaner that prevents algae build up on the aquariums surface. This is accomplished by the RoboSnail"s unique ability to clean the aquarium"s surface once a day without user intervention. The constant preventative cleaning performed by the RoboSnail stops algae from taking hold on the aquarium surface. At first, it is almost invisible. But as it builds up on the aquarium surface over time, it progressively becomes more difficult to remove. Long periods of neglect result in stubborn coralline algae, as found in marine tanks, or a hazy, unsightly build up that can be found in all aquariums. Since more effort is needed to remove it, the result can be a scratching of the aquarium surface and longer, more difficult maintenance sessions. AquaGenesis International has been founded on the premise that we are here to revolutionize the tedious and time consuming task of maintaining and keeping aquariums.
