Dunno what brand ours is but it does climb walls and gets a lot of acorns. We have to replace the wheels occasionally cuz they wear smooth and can't climb. I think a new one would be about $400 to maybe six tops. We have a salt system and tank filter with some kinda multi ply cloth we have to hose down once each season. Our pool is small...only 13K gallons. I'll check the brand of the 'crawler' and post later. It does a good job.
