If you like the concept of Neato's WiFi-linked robot vacuum but feel that $699 is too rich for your blood, you're in luck. Neato is unveiling two more affordable Botvac models, the $399/£399 D3 Connected (above) and $599/£549 D5 Connected, that promise WiFi and the core cleaning features at better prices. The D3 still has mobile app access and laser-guided navigation, but trims costs through a lower-capacity battery, a basic filter and fewer features -- you won't get the high-end model's boundary markers, eco/turbo modes, manual drive, spiral and side brushes or on-robot scheduling. Move up to the D5 and you'll get the battery, brush and filter upgrades as well as boundary markers. Also, only the D5 has in-app cleaning stats and a Find Me locator right now. Those are coming to the Botvac Connected flagship later, but won't be available at all for the D3.
