What each design costs to run
One bagged dock, one bagless dock
The bagless Deebot X12 OmniCyclone uses no bags. The Roomba Max 715 uses bags at $19.99 for three, about $27 a year at the maker's four bags a year. The bagless dock swaps that for filters and a bin you empty by hand.

Questions
What readers ask
Do bagless docks cost less than bagged docks?
On consumables, yes for bags. The Roomba Max 715 bags are $19.99 for three, about $27 a year. The Ecovacs dock needs none, but it needs filter care.
How often does a bagless dock need emptying?
The Ecovacs maker says up to 48 days before the bin needs emptying by hand.
Does emptying a bagless dock expose you to more dust?
You empty the Ecovacs bin yourself, and a scraper ring cleans the bin wall. The Roomba maker says its bag traps and seals dust. No exposure test was found for the Ecovacs.
