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 Tyra Smith

There are some negative reviews about this vacuum cleaner, but reviewers wrongly compare it to the best robot vacuums Roomba, Neato or any other robot vacuum for a few hundred bucks. There are no frills with this vacuum, but it is a simple, basic vacuum that works as intended. Overall I'm happy with this vacuum for use on tiles in my kitchen, it cleans well and for $100 it's good for my use. Buy this for potential buyers if - you don't have a threshold or transition bar between rooms - you have a hardwood floor or just a short pile carpet - you don't mind turning the vacuum on and off - it doesn't have a base station - you don't have anything on the other hand, if that vacuum cleaner doesn't have a room map, area cleaning, or brush - the suction port of the vacuum cleaner is in the center of the vacuum cleaner (that's why it has those little white brushes)
