Ecovacs Deebot 901 review: an affordable floor-mapping robot vacuum

Robot vacuums equipped with mapping offer a host of advantages over sensor-driven models. Their high price tags, however, can be a deterrent, especially if you're not yet sold on automating this household chore. Enter the Ecovacs Deebot 901, which fills a needed niche. It's a robot vacuum with premium features like floor mapping and Google Home and Amazon Alexa voice control, yet it's priced for more modest budgets. It measures 13.9 x 13.9 x 3.3 inches, with about an inch or so of its overall height coming from the LDS (laser distance sensor) turret that sits atop the vacuum's rear.
