These smart devices are among a million products on sale for Black Friday this year.

I love smart tech.

Between smart cameras, sensors, and robots and every kind, these machines can save time and effort.

Mammotion Luba 2 is hands down the most consistent mower I’ve tried

They’re often expensive though, which makes Black Friday the perfect time to invest in them.

(Read my full review.)

The Luba 2 is rugged and will handle everything from a medium-sized yard to a field with ease.

Segway Navimow

The bots come in different capacities, each with their own discount for Prime Day.

(Read my full review.)

For smaller yards, the Navimow is a great option, and it’s incredibly reliable.

Eufy Solocam

There are actually two cameras in eachone for a macroview and one for a microview.

The two cameras on sale are the hardwired floodlightstheS330andE340.

It is too frustrating to be away and have something just out of range.

Aqara E1

For this reason, I have really liked the Aqara 2K Indoor Security Camera E1.

Unfortunately, that hasnt been my experience.

Even within a brand, the variance from one model to the next can be jarring.

The S8 Pro Ultra

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 somehowexceptionalon both carpet and hard floors.

Switchbot k10+

The mopping feature isnt simply an add-onit competently gets the floor clean.
