I don't have a pool (well, not a personal one, anyway; I live in an apartment complex), but I do have a robot vacuum, and I know the joy of watching a little machine clean my floors while I do other things. If you apply that same logic to pool maintenance (which I imagine is a lot more annoying than keeping your floors clean), then investing in a robo pool cleaner makes a lot of sense.

And, right now, you can get one of Amazon's top-rated models for a fraction of the price. As of May 6, you can get the Beatbot AquaSense 2 for $849 at Amazon, down from $1,298. That's a 35% discount or $449 savings. It's also the lowest price we've seen this model go for. The only problem? Amazon marked this as a "limited-time deal," and the countdown clock shows it ends in about 16 hours.

This thing works just like an indoor robot vacuum; it maps out its cleaning path and then uses an onboard 4-core CPU and 16 sensors to navigate using an S-path for the pool floor and an N-path to scrub the walls and waterline. It also has a "Double-Pass Scrubbing" feature for the waterline, so it'll get the grimiest spots twice per pass. Bonus: When it's done cleaning (or when the battery runs low), it automatically parks itself at the surface of the water so you don't have to go diving to retrieve it.
