Does it work on hardwood floor?

What serie is good?

where did you buy it?

We got it from Costco as regular price $250. Can't wait for discount.

It works on hardwood floor fine. And the result is better then my vacuum cleaner.

It saves me a lot of time, and helps to relive the pain on my shoulders.

I wish I had it earlier. I think every house keeper should have one. Seriously.

Now, I am looking for robots that can do dust and make meals
