Your Roomba Will Soon Be Able to Find Your Home's Wi-Fi Dead Zones

You may have noticed that your Wi-Fi doesn’t work equally across your whole home. Maybe your bedroom is across the house from your router, and you just can’t manage to get Netflix to work there. You may not know exactly where the dead spots are, though. Soon, your Roomba could help. According to The Verge, a forthcoming update to the iRobot app will map your home’s Wi-Fi strength as the Roomba moves throughout your house, allowing you to figure out where the signal cuts out.

Even if you already know that your Wi-Fi is spotty in certain parts of your house, the Wi-Fi map would show just where those dead spots are and the extent of the problem. Armed with more knowledge of your apartment’s signal issues, you could figure out a better place to put your router or know when you really need to buy a range extender.

Don’t expect to see the feature pop up on your app immediately, though. Though it should roll out in mid-January, it will only apply to a small subset of users of the company’s high-end vacuums, the Roomba 960 and the Roomba 980. Those vacuums, which have Wi-Fi, already create a map of where they’ve cleaned that you can access in the app, so it’s not a huge leap for them to show where they experience shoddy internet connectivity. The function will be in beta testing for a while, and only a few hundred users who request access will be enrolled in the program at first.

Should it be a success, though, you can expect to see Wi-Fi mapping on the company’s next generation of vacuums, and depending on its popularity, it could be a functionality other robot vacuum manufacturers begin incorporating, too.

This tiny air conditioner fan, which touts a 4.6-star rating, is unique because it plugs in with a USB cable, so you can hook it up to a laptop or a wall outlet converter to try out any of its three fan speeds. This won't chill a living room, but it does fit on a nightstand or desk to help cool you down in stuffy rooms or makeshift home offices that weren't designed with summer in mind.

New Virtual Tool Lets You Rickroll Your Next Zoom Meeting

Anyone who says the Rickroll is played out isn't thinking big enough. The classic internet prank—in which web users are tricked into watching the music video for "Never Gonna Give You Up" by Rick Astley—has been reimagined countless times in a variety of contexts. Now, Rickrolling has entered the Zoom era.

As Gizmodo reports, creative technologist Matt Reed has invented a genius tool that lets you Rickroll your coworkers. After receiving an invitation to a Zoom meeting you're not excited to attend, head to InviteRick.com and submit the invite link.

The tool is still in beta, and Reed has to initiate every Rickroll manually. That means Rick is only available to make surprise Zoom performances on weekdays between 10 a.m. and 4 p.m. EST. Once you've signed up for the service, you'll be added to a queue and updated on when to expect Rick to make his appearance. When the pop icon does eventually crash your Zoom, he'll stick around for approximately 15 seconds before making his exit. Hopefully that's enough time to completely derail the meeting.

InviteRick.com may only be around for a short while (Reed admits it likely violates Zoom's terms of service), so spread that '80s corniness while you still can. In the meantime, check out these epic Rickrolls from a simpler time in history.
