That doesn't mean you can't still enjoy this futuristic technology!

A great robot vacuum at an even greater low price

There are lots of affordable robot vacuums on the market, many of which did very well in our rigorous lab tests. One in particular, the ECOVACS DEEBOT N79, is currently on sale, and may be perfect for your budget and your cleaning needs.

The DEEBOT N79, one of the most popular robot vacuums on Amazon, typically costs $199.98. Right now, however, you can use our exclusive promo code (ZK4CJTKR) to knock $40 off the price and get it for $159.98. This code is good through Friday, Oct. 20, so don't miss your chance.

The good, the bad, and the cleanly

We just tested the DEEBOT N79 in our lab's robot vacuum obstacle course. We sought to see how the vacuum consumers are loving actually performed against things like thresholds, high-pile carpet, big messes, and more. Truth be told, it did pretty dang well, but it's not perfect. You can read the in-depth review here, but here's the basic rundown:

• Has a remote and its own smartphone app, but it's not compatible with Alexa or other smart home technology
• Doesn't get stuck as often as other vacuums (even high-end models)
• Suction is pretty good, but not amazing (read: average)
• Not the best at climbing onto high-pile area rugs
• Takes longer than average to complete a cleaning cycle...
• But you can set schedules so it does its thing while no one's home

All in all, the real value of this robot vacuum is its low price, and with the additional 20% savings, it's the perfect way to scratch the itch of having a pet robot that cleans for you without spending too much.
