You should highlight this to EUFY’s advertising:
“Less dust, less allergies”.
Though we had and have a very clean house, after one year of Willy’s fantastic work, I feel better with my cough caused by a dust allergy.
Every time I take a look at his container I know why I am feeling better.
Strolling around in the house all this dust would be whirled up and inhaled.
GREAT IMPROVEMENT!
Totally agree after owning a RoboVac 30C for about 6 months 
I’ll test it out if anker sends me RoboVac 
my 11c is still going strong after 2 years of use. It works ok but I plan to replace the 11c with a 30c or something better once the 11c dies.
I’ve never had a Robot vacuum, had not thought about another layer of defense against allergens. I have two of those Honeywell air purifiers running 24/7 to help, they grab a lot from the air but they can’t obviously help with larger particles that are on the floor. Interesting.
There is one thing which many people dont think about.
The dust in the air will fall down to the floor and will be whirled up by walking around and you inhale this the whole day.
Another indication of this fact for me : There is really less dust on the furniture.
And last and least my cough is so much better after using that robot for more than a year.
We are a couple in the house, no pets.
I don’t know what these air purifiers grab. But I suppose their radius is limited.
