The Roomba 980 performs as stated. Excellent pick up and battery life. The WiFi connectivity is handy for as needed cleaning between scheduled times. We are very pleased with the unit.

positive

I like the color and material but that's about it. THIS WILL DO NOTHING TO PROTECT YOUR SCREEN OR CAMERA. My screen stuck out from the case, and my camera almost sticks outside the provided lip. It'd be worth spending a little bit more to protect your $1000 phone.

Ex Output:
negative
