Are there any pool cleaners - preferably robotic - that you can leave in the pool 24 / 7 and only take it out occasionally to empty the bin / bag? I'd prefer something that you can schedule to run automatically once a day or so and that can hold enough debris that it only needs to be emptied every couple of days (preferably once a week). My in-ground pool constantly has debris being blown into it from various sources (trees, bushes, ground cover, dog hair), and I have times where I'll have to work a couple 80+ hour weeks in a row, and/or travel. While I like taking care of the pool, anything I can do to minimize the time required to do so could be very helpful.
