A:AnswerBin stores exactly .66 gallons, says so right in the Specs section for the eufy Clean-X8 with Self-Empty Station (as possibly they have added or corrected it over these last 6 months). 11 gallons would probably be a VERY large Empty Station!
A:AnswerYes it works well on hard surfaces, the majority of my downstairs level is ceramic tile as well as some carpeted areas and it switches between flooring types well and adjust to any variation of heights pretty seamlessly.
