'ZDNET Recommends': What exactly does it mean?

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

The Roomba with a robotic arm is still $300 off after October Prime Day

The Roomba Combo J7+ will make your floors shine with little work on your end -- and it's 27% off even after Amazon's Prime Big Deal Days sale ended.

If you're a Transformers fan, I present the Roomba Combo J7+. This robot vacuum and mop combination easily transitions from hard to soft floors by lifting the mop away from carpets with a retractable arm.

The Combo J4+ is a self-emptying robot vacuum that is also smart enough to avoid obstacles on the floor, from dirty socks to pet waste, and you can now buy it at $799 (down from $1,099).

Its dual multisurface rubber brushes are effective at picking up small debris, dust, and hair that other robot vacuums can miss. The rubber brushes have no bristles to prevent hair tangles and ensure more consistent suction, making it a great fit for homes with kids and pets. 

Review: Roomba Combo J7+: A 2-in-1 robot vacuum done (almost) right

The J4+'s small mopping pad and water tank make it more suitable for medium homes or mostly carpeted areas, as larger areas require refilling the water tank several times during a cleaning session. That being said, we can't knock its mopping performance: This Roomba features SmartScrub, a technology that mops back and forth with downward pressure to get rid of tough stains. 

Even if the Prime Big Deal Days sale ended, the Roomba Combo J7+ is $300 off, available for $799 for a limited time.
