Aiper Scuba SE vs E1 vs S1 Cordless Pool Cleaner 

Thanks for this review. Being able to see these in action was fantastic. Makes decisions a bit easier.

It get stuck on the white devices for suction at the bottom of the pool. .

I've had two of these units so far - one of them failed after 3 uses and one after 2 uses. If they want to send me another one, I'll try it before I give up on them, but there's no way I would buy one today. They believe these were mainboard failures. I'm guessing they are either poor quality or they aren't leakproof and water is getting to the mainboard.

Do any of them clean the stairs?
