Eufy 11S RoboVac is the highest rated robo vacuum on Amazon in this price point. It sells for $300 right now.. You can read the reviews here: https://www.amazon.ca/Eufy-BoostIQ-Super-Thin-Self-Charging-Medium-Pile/dp/B079QYYGF1/ref=sr_1_1?ie=UTF8&qid=1546728117&sr=8-1&keywords=eufy+robovac+11s Works great, very quiet, cleans well. Battery lasts for over an hour and then it automatically returns to its dock to charge. Comes with remote control to schedule daily cleanings, or type of clean (corners, single room, spot clean, etc.) Will not fall down stairs, and automatically senses walls, furniture etc to avoid running into them. I've been using this for a couple months and love it, but moving to a new house that has a built-in vac system. Comes with a new set of filters, rolling brush and side brush. If you want to see it in action before purchasing I'm happy to show it at my condo in Vic west.
