Robot Reviews

CNET has reviewed several brands of robotic vacuums Sept.2020, with the Roomba S9 most effective while also most expensive. A Neato robot is second for lower price, and Eufy for the cheapest. Several others are compared, but no review is made of Samsung -- which I happen to prefer and tested extensively in posts here.
