I'm slowly doing my research to determine which robot cleaner to purchase, when I make the jump and replace my Polaris 360. One thing I'm really looking for is a unit that has a filter basket system that is easy to empty. With the mesh bag on my Polaris 360 I found it difficult to get all the sand out of it, and usually let it completely dry first before attempting to empty.
With all the top of line robot cleaners I've seen, the ones that interest me the most for other features like swivel cord, custom cleaning programs, remote control, great waterline cleaning, included caddy, etc., seem to then fall short in that you have to flip the unit over to remove the debris filter/basket, and some of them seem to have either very small compartments with car air-filter like filters, or cloth bags. Whereas the units that may have other shortcomings like no swivel cords, not as impressive cleaning abilities, etc., seem to have better top-loading baskets that seem easy to remove, empty and clean.
For all you robot cleaner owners out there, I'm curious to hear your experiences and preferences on top vs. bottom filters. And throw in the discussion mesh baskets vs. cloth bags.
Thoughts? Pros/Cons?? Feel free to name specific makes/models.
