Review on SereneLife Pure Vacuum Cleaner - Upgraded Lithium Battery 90 Minute Run Time - Automatic Bot for Stairs, Pet Hair, Allergies - Friendly Robotic Home Cleaning for Carpet & Hardwood Floor - White by Chere Reiners

Product works great! It was just what we needed to help with the kids under the kitchen table after the meal! He surprised me with his ability to move well between chairs and table legs. His ledge protection function worked as described, knowing he could turn around and not fall off the stairs into another room. The noise is obvious when it's on, but I think that's an indication of its powerful suction. We don't have carpet so it's likely to be a bit noisy due to the tile and hardwood floors. But overall I'm very happy with this product, it cleans well - just what we need.
