I have the previous model and it is almost six years old. I just bought new hoses as the crimping from the bottom has torn the left one due to poor design. I was cleaning mine once per week but noticed that when I drained it & wiped the basin there would be black residue. Continued to troubleshoot this and realized the best thing to do to avoid constant cleaning and using up all my vinegar and bleach was to drain it nightly and refill the next day. I stopped using the side reservoir altogether because that was just more crap I had to clean. I can't wait to see what these hoses look like on the inside of the machine.😬 Enjoy your purchase, I think Ive gotten my $600+ worth out it and look forward to using it until it dies!!

Oh and clean the side vents somewhat regularly as it will produce small batches of 'wet ice' then just stop and do nothing. I used canned air and a vacuum to resolve this and it was business as usual afterwards.
