If you’re not familiar with the iLife V3s Pro, don’t fret. It holds a spot in our list of the best robot vacuums. In our lab tests, the iLife V3s Pro picked up 99.5 percent of all pet hair, and scored a 97 percent overall — that’s cleaning up hair, Cheerios, and sand on both hardwood and carpet. It also did well in real-world tests, as you can read in our iLife V3s Pro review. Now, with a budget robot vacuum, there are a few tradeoffs. The V3s Pro cleans in a random pattern, which means that it will take longer to vacuum a room than a smarter robot vacuum that travels in a grid. And while the V3s Pro comes with a remote control, you can’t connect it to your Wi-Fi or control it with an app on your smartphone. But you can program it to run when you’re not at home. Normally, the V3s Pro is priced at about $159, which is pretty good already, but this deal knocks it down to $77, which is a price we don’t think we’ll see again this month. (or this year).
