Robotic vacuum really work??

I concerned "Robotic vacuum really work?" for one year.
When I read someone's writing about robotic vacuum, I decide to buy, specially Orange color Pporo.

First few days, I expect too much Pporo works to cleaning. I think Pporo works well and save my time.
Also Pporo come with Jaaloo. This handy vacuum is wireless. So I can use anywhere.

Pporo has SSW mode, SSW stand for "Spider Spiing Web" So, Pporo vacuum like a spider on the floor.

Laundry and toys are all ove the floor. so I have to pick that up before Pporo vacuum. and I closed each room's door.
My Pporo can works 2-3 days without recharge. I exchanged Pporo filter after 3 times Pporo work.
But this is depends on how people using.

Pporo can pass doorsill under 2 cm. but my room doorsill's are double. so he stuck sometimes.
So, I put something on the doorsill, so Pporo can not pass.

Pporo also has wet mopping function, this is really works. all my family love this function.
Pporo moped lots of dust on the floor.

I definitly exchange when Mamirobot upgrade new version of Pporo.
I love robotic vacuum now.
