See our ethics statement.It’s another Prime Day — or a Prime Big Deal Day in Amazon parlance — which means another day to save a dollar or two on some great new gear for your smart home. Whether you’re looking for a robot helper to clean your floors, an extra set of eyes to watch over your property, or another smart speaker to bark commands at Amazon’s Alexa voice assistant through, there are some good bargains to be had during Amazon’s Fall Prime Day event.As usual, robot vacuums are seeing some decent sales, including on the top-of-the-line models that don’t see discounts as often as the rest of the bunch. (My advice is never buy a bot that’s not on sale because they're always on sale). Ecovac’s newest flagship robot vacuum, the X2 Omni, launched last week and is already $200 off. I’ve started testing it, and it’s an impressive machine; its square shape gives it the advantage of getting into corners better than most rounder ‘bots. The higher-end Ring smart security cameras are also getting deep discounts: the Ring Pro 2 Video Doorbell and Ring Floodlight Cam Pro add radar motion detection and better video quality over the base models. These are rarely on sale and are seeing up to $100 off.Here’s a roundup of some of the best deals on good products that I’ve spotted so far. I’ll update this throughout the sale’s event, so check back often. The Roomba i4 Evo robot vacuum (the Roomba i3 by another name and with a bigger battery) cleans just as well as the flagship Roomba j7 and can map your house for more accurate vacuuming. But there’s no AI-powered obstacle avoidance or virtual keep-out zones, so you do have to clean up your clutter before you run it.The Roborock Q5 Plus is a great robot vacuum that can empty itself and features mapping and virtual keep-out zones with lidar navigation for the bargain price of $399.99. This is one of the few Roborocks you can get without a mop, making it a good choice for homes with lots of carpet.The excellent Ring Pro 2 video doorbell is $100 off —a very good price for a very good doorbell with the best video quality, good connectivity, and superb motion detection. Read my review.The best Amazon Alexa smart speaker, thanks to its excellent sound, nice design, and built-in smart home hub, the Echo (fourth-gen) is a great way to get started with the smart home. Along with being a smart speaker it’s also a Matter controller, Thread border router, and Zigbee bridge, so can connect all your gadgets to your smart home. This versatile smart lock is seeing its lowest price. It supports Apple Home Key and has a built-in fingerprint reader plus a touchscreen keypad. It’s Matter-compatible and requires an Aqara Zigbee hub for Matter support (the Hub M2 is also on sale at $41.99, 30 percent off). Read my review.The Ecobee Smart Thermostat Premium does a lot. As well as adjusting your HVAC intelligently based on whether you’re home or away and/or where you are in your home, it’s also an indoor air quality monitor, smart speaker (Amazon’s Alexa or Apple’s Siri), and a hub for Ecobee’s smart security system.The excellent Apple Home-compatible Meross Smart Power Strip is down to $32.54 (with on-page coupon). You get four sockets and 4 USB ports, all controllable through Apple Home, Alexa, and Google Home. With the MyQ Chamberlain Smart Garage Control, you can open and close your garage door from any location using your smartphone.
