Best Smart Home Tech Deals for October Prime Day

Over the past year, I’ve tested tons of smart cameras, sensors, and robots of every kind, and I’ve found some favorites. What would be great about smart tech is if it were less expensive, so everyone could realize the accessibility and labor issues it can solve. That’s why Prime Day is a great time to consider one of these devices when the prices make them more affordable—here are my favorite smart tech devices from past year that I’d recommend buying while they’re on sale.

Best robot lawnmowers

Having now tested a number of lawn-mowing robots, the ease and reliability of the Luba 2 makes it my hands-down favorite. (Read my full review here.) Full of features from video monitoring to GPS location if removed from the yard, the Luba even has lawn-printing capabilities now. (I was underwhelmed by this but did print a bunch of stars on the lawn for the Fourth of July.) The only reason to choose a different mower is if your lawn is too small or has a lot of obstacles to mow around. The Luba 2 is rugged and will handle everything from a medium-sized yard to a field with ease. The Luba 2 comes in different capacities, each with their own discount for Prime Day. 

• Luba 2 AWD 10000: regularly $4,099, now $3,849

• Luba 2 AWD 10000H: regularly $4,099, now $3,849

• Luba 2 AWD 5000: regularly $2,899, now $650 off with coupon

• Luba 2 AWD 5000H: regularly $2,899, now $2,649

If your lawn is smaller, you might consider the Segway Navimow. (Read my full review here.) The distinction I make between the Luba 2 and the Navimow is that the Luba is really rugged, but lacks the gracefulness to turn on a dime or tightly navigate around obstacles. For smaller yards, the Navimow is a great option, and it’s incredibly reliable. It does not enjoy a dip in the yard or a hill, so you’ll want to ensure the landscape is decently flat, but it handles an incline without a problem.

Best outdoor security camera

There are lots of good outdoor security cameras, but whenever I’m done testing others, I put my Eufy Solocams back up. There’s lots to like, including the extraordinary range of vision that comes from the spherical pan-and-tilt that allows you to rotate the camera almost 360 degrees. There are actually two cameras in each—one for a macroview and one for a microview. The microview is spectacular for detail: I can actually get a detailed look at individual plants in my yard while I’m away. I love that you don’t need a monthly plan if you get a Eufy hub for storing clips locally, and that the live view comes up reliably each time with minimal wait time. The two cameras on sale are the hardwired floodlights—the S330 and E340. I have both up as we speak, but also be sure to look at the solar powered s340, which is not on sale but is still worth it for spots where you don’t have the ability to hardwire. 

Best indoor security camera

I firmly believe that all security cameras should be able to pan and tilt. The ability to move the focus around the room and find what you need is essential, particularly for an indoor camera. It is too frustrating to be away and have something just out of range. For this reason, I have really liked the Aqara 2K Indoor Security Camera E1. Its solid, low profile never gets knocked over, and allows you to sweep a room for exactly what you’re looking for.

Best robot vacuums

I wish I could say that all robot vacuums, particularly the expensive ones, were comparable and that you’d probably get a good one if you just spent enough. Unfortunately, that hasn’t been my experience. Even within a brand, the variance from one model to the next can be jarring. However, Roborock models have consistently been my favorites over the last year. If I was going to buy a robot vacuum tomorrow, it would be from the Roborock S8 line. The S8 Pro Ultra is somehow exceptional on both carpet and hard floors. It has the fewest hiccups in terms of getting lost, getting stuck, or having to clear the rollers. The mopping feature isn’t simply an add-on—it competently gets the floor clean.

If you’ve got a smaller house, an apartment, or just a dedicated space you want to add a robot vacuum to, my far and away favorite is the Switchbot k10+. The diminutive size allows it to get closer to walls and around chair legs than regular floorbots. While technically a vacuum and mop, the mopping function isn’t worth bothering with—if you just focus on it as a vacuum, it will impress you.

Best smart diffuser

This smart scent diffuser, which I thought would be fun but nothing more, turned out to be one of my favorite finds of the year. Two aspects I love: You can turn it on and off or schedule it from your phone, so it doesn’t get overwhelming, and you can load two different scents and it will show them in your phone app. The diffuser ($39.99) isn’t on sale for Prime Big Deal Days, but that’s no matter. Where you’ll get stung is the refills, and some of those are 20% off right now, so load up.
