Household vacuum cleaners question?

eufy RoboVac 11S MAX
I have two of these. One for the fist floor and one for the second. You can catch them on sale on Amazon for a decent price. Love it. With the cat and dog in the house there was always hair floating around. These things go off once a day and do there thing. I am amazed at how little dust there is in the house now. I empty the bin every morning and once a week clear the hair out of the roller and all is good.
