Review on SereneLife Robot Vacuum Cleaner - Long-Lasting Lithium Battery, 90-Minute Runtime & Self-Navigation for Pet Hair Allergies. Effortless Cleaning on Carpet, Hardwood, and Tile Floors. by Jennifer Wilson

I'm really impressed with this guy. This is a budget robot vacuum that lacks many of the key features on the ticket, but where it lacks it makes up for in cleaning power. The attached pictures were my litmus test. I scattered tissue paper randomly all over the floor and let it sit overnight. Very surprised by the morning coverage. Overall I would say this is a good vacuum for a small space. Just charge it up and let the guy run all night. Pros: Easy to set up. Good suction power. Decent working hours. Cons: No smart features. A little noisy.
