Beatbot AquaSense Cordless Robotic Pool Vacuum Cleaner – Intelligent Path Opimization, Cleans Floor, Walls, and Waterline – Suitable for Above & In-Ground Pools up to 2,260 sq.ft, Light Gray

I got this to replace an Aiper that had died two months after its warranty expired. This time, I used a credit card that doubles the manufacturer’s warranty. So – 4 years of warranty.The unit is physically larger and heavier than the Aiper. I’m glad I didn’t go for the “Pro” version which is clearly even larger and heavier. It seems to be well made, and although it’s heavier, it’s just as easy to carry as the Aiper, because the ergonomics are better. Nice big grab handle.It has Wifi connectivity when it’s out of the pool. But it does not accept Wifi passphrases with embedded spaces. I asked Beatbot’s tech support about it, and their suggestion was to change my wifi passphrase. Umm, not happening. I have WAY too many gadgets with that passphrase. Note that I say “passphrase” and not “password”. Wifi has supported passphrases since its very inception.Luckily, the cleaner works without wifi.Another issue – that I didn’t know before receiving it; The manual says to turn off your pool filters while the cleaner is cleaning. I’m betting that’s because the noise in the water confuses their ultrasonic sensor.I don’t think that was mentioned in the Quick Start pamphlet. Anyway, the cleaner does work with the pumps running, but I think it’s a little confused. My pool is a simple rectangular shape, and for some reason instead of going back & forth with the shape, the cleaner cuts steep diagonals across it, climbing the walls a bit at a severe tilt.The pool hadn’t been properly cleaned since the old cleaner gave up, and although we have a power cover on it, a quantity of leaves had wound up on the bottom. The instructions say to clean the pool by hand before using the cleaner for the first clean of the season. Heck with that! I bought this $1K cleaner to *clean*, not to watch me clean :).So I plopped the cleaner in. It did it’s thing and then parked at the edge of the pool. I fished it out, and the hopper was completely full. Recharged it and did it again the next day. It’s been 3 days of once-a-day cleaning, and now the pool is almost pristine.WRT charging: The unit comes with a charging dock with two big spring loaded terminals that contact connection spots on the side of the cleaner. This seems like a very effective system, and superior to the little rubber-tipped plug that the Aiper had. Much easier to keep clean.The cleaner started parking itself at the far side of the pool, that has a retaining wall. Sure would be nice if I could tell it to park over HERE instead. But not deadly – my pool pole reaches the other side, and the supplied hook is very good – very substantial.The last few cleans, the unit stopped parking itself on the wall. Rather, it just stops somewhere in the middle of the pool. Not deadly – it’s easy to fish it out with the pole.In conclusion, this seems to be a good cleaning machine, with some high-tech warts. But no deal killers.
