Ecovacs Deebot N79S robot vacuum review: Some advanced features at an affordable price

Robot vacuums typically fall into one of two categories: pricey premium models that come with cool features like app control, mapping navigation, and smart-home support, and budget-minded models that that, well, don't. The reasonably priced Deebot N79S bridges that chasm a bit by offering a simple but elegant app experience and Alexa-enabled voice control. The N79S sticks pretty close to the blueprint of other Deebot robot vacuums we've tested: a simple circular design--13.9 inches in diameter in this case--in a modest black color. The Auto button and Wi-Fi indicator sit on the brushed-metal top and there's a power switch on the side. Underneath are a single roller brush, two spin brushes, a pair of treads and a nose wheel.
