The amount of work to clean a cannister vs an AC110 is night and day different.
The AC takes about 5min start to finish to do it's maintenance. Is super easy to boot. Vs a cannister.
Cannister: First have to disconnect the hoses. Move it out, get the top off. Clean it all, get it back together, and pray the seals hold. Move it back in place, reconnect the hoses.
AC110: get a bucket, put 5gal of tank water in it. Rinse bio-rings put in tank, rinse sponge put back in filter, put rings back, done
Both my 125s have 2 filters so each week a filter gets cleaned. Next week the other, following week back to the first etc. Over a couple years years all the work to clean a cann adds up.
