I was disappointed in this vacuum robot. It was easy to set up on my phone, with the Bluetooth, but that’s about it. It claims “will not get stuck,” it got stuck on multiple occasions. I kept having to get it; which defeats the purpose of it being hands free. It also doesn’t have enough suction in my opinion. It should be able to pick up a small piece of paper…it didn’t. It just kept going over it and not sucking it up, even made sure there was nothing blocking the mechanism, it was just weak.
