I travel a lot and was getting fed up of coming home to an algae covered glass that I could not see through. so I recently went and splurged on a RoboSnail (http://robosnail.com">http://robosnail.com</a>) for my tank.
This thing is awesome and the customer service is great
My first unit did not work as expected, they were on the phone with me and then sent me a new unit that they tested before sending and it works great
My front glass panel is clean every day. It could be better but compared to the alternative automatic units that cost close to a thousand $, this is way better
For those considering - it only does the front panel and I would only have it on a larger tank (mine is 150g display)
