Amazon has the Samsung POWERbot SR2AJ040W WiFi Robot Vacuum on sale for just $390.06 right now, and that is good for a little more than $100 off of its regular price. That is actually a really good price for a robot vacuum of this caliber, and definitely worth picking up.
The Samsung POWERbot is a robot vacuum that connects to your WiFi. It needs WiFi connection so that you can control it with the POWERbot app on your smartphone, and so that Alexa can control it. That's right, this is an Alexa-enabled robot vacuum, so you can use Alexa to tell it to start vacuuming whenever you want. With the app, you'll be able to tell it where to go, as well creating a scheduled time for the POWERbot to start vacuuming each and every day. The POWERbot has CycloneForce technology which keeps it from getting clogged up, which is one of the biggest issues with robot vacuums these days. Additionally, Samsung is touting about 10x more suction power on this model, compared to its earlier models. This means that you are going to get more dirt up out of the carpet and more pet hair as well, than with other robot vacuums on the market. Making this a good option for those that do have pets.
