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 Jessica Gibson

For the price the product is perfect and as described. Impressed with the amount collected in 5 minutes. The noise isn't as loud as a vacuum cleaner, but you can definitely hear it from the next room (not a problem for me). It's very smooth. It didn't snag on my carpets, but it did take a little more strength to get past the streak in my kitchen. Overall I am satisfied with the performance of this product.
