Does anyone have an automatic aquarium glass cleaner?

Hi everyone… I'm new to the forum, and although I've kept freshwater aquariums for about 30 years, I consider myself quite a novice and would like to know your opinion on algae on the glass. For about 15 years, I've had a 30-gallon aquarium in a section of my living room where three of its four glass panels are visible, which I love. My house is quite bright, which makes algae grow quickly on the glass. Apparently, the presence of algae isn't a bad sign; it even indicates that the aquarium is healthy, and the truth is, my fish live for many years.

I don't know how often you clean your aquarium glass, but I've seen that they supposedly sell automatic cleaners for this purpose ("Robosnail" or "MOAI") and I was thinking of buying one, even if only for the area most affected by algae. However, I haven't found any real reviews from people who have bought them, nor any unboxing videos, and that doesn't reassure me because it doesn't even guarantee that you'll actually receive the product after paying for it. Does anyone here own one of these cleaners? What was your experience?
