Robot vacuums have gone from novelty idea to must-have appliance in today’s homes. The tiny cleaners have become one of the most popular items on Amazon’s Electronic Gift Guides over the past few years and the EcoVacs DeeBot N79S Robot Vacuum Cleaner is more than 50% off today for a limited time.

The promotion is part of Amazon’s Gold Box Deal of the Day, and you can grab the N79S model at one of the lowest prices Amazon has ever offered. The EcoVacs DeeBot N79S earned the “Amazon’s Choice” sticker on the company’s website, with over 1,000 reviews and a 4-star rating.

As with any Gold Box Deal of the Day, this promotion is only scheduled to last for one-day, or while supplies last. You can grab one for $139, that’s a savings of 53% over the regular $299 price-tag. You can find the offer right here on Amazon.

This model offers max power mode, which allows you double the cleaning power when using the app or remote control for quick jobs or accidents. This device also works with Alexa or Google Home voice commands, so you can tell the N79S to get to work if you need a cleaning on the double. Robot vacuums work best when they clean everyday, and you can use the ECOVACS App to schedule daily cleanings at a time that’s best for your household. The N79S App can also give you alerts on your accessory status, and you can receive error alerts if something interrupts the cleaning cycle.

As for cleaning, there’s the standard auto-clean function that you use during scheduled cleaning or quick jobs, but the N97S also offers other specialized cleaning modes. You can set it for single room, spot mode for targeted cleaning, or set it to edge mode for hard-to-clean edges along the walls. Just like other vacuums this model includes anti-drop and anti-collision sensors to keep it and your furniture safe, and it has a hefty 120 minute battery life with auto-return charging. You can also benefit from automatic software updates, air filtration, an anti-scratch finish, and sturdy brushes to get your rooms clean.
