Approximately no one had a robot vacuum with an arm on their CES 2025 bingo card. Roborock made one anyway, and the Roborock Saros Z70 is officially available to preorder (with shipping beginning in May). The Saros Z70 will cost $1,899 — slightly less than the $2,000 we originally expected. And if you buy your Saros Z70 during this initial release window, that $1,899 actually covers a bundle that includes a second Roborock vacuum of your choice.

The eligible bonus models span from robot vacuums to upright vacuums, including the popular Roborock Dyad Pro Combo 5-in-1 wet and dry vacuum (a $659.99 value) or the Roborock Qrevo S5V (a $799.99 value). No end date for the BOGO promo has been given, but quantities for the free vacuums are limited.

Though there's no question that a robotic arm for picking up obstacles is cool, it's the practicality that I was questioning. If you were on the fence about spending that much on a vacuum, the cost-effectiveness gets a serious boost when you get two nice vacuums for the same price.

What's so special about the Roborock Z70?

The Roborock Z70 goes past the small obstacle avoidance technology that has become a navigational staple in recent years and topples into obstacle removal technology. It performs such with a robotic OmniGrip arm that unfolds out of the top of the robot vacuum to grab the obstacle claw machine-style, and drops it in a nearby designated area. (The live demo at CES 2025 showcased the Z70 putting socks into a basket.) The arm's pickup capabilities cover four different types of obstacles and must weigh under 300 grams: socks, paper, small towels, and lightweight shoes. I'd personally benefit the most from the arm being able to grab pet toys.

People more swayed by practicality than a hit-or-miss high-tech feature might find the bigger grab here to be the Z70's incredible 22,000 Pa of suction power. That's 12,000 Pa more powerful than the Roborock Qrevo Master, my favorite overall robot vacuum of 2024 that cleans with 10,000 Pa, and 3,500 Pa more powerful than the Roborock Qrevo Curv that has sold out several times.

The Saros Z70 isn't the only new Roborock in 2025

The Saros line also includes two other new flagship models that don't feature the robotic arm: The $1,599.99 Saros 10 and Saros 10R. Both are the same super slim 3.14-inch height as the Saros S70, but both feature a mixed assortment of features from the Z70.

The Saros 10 cleans with the same 22,000 Pa as the Saros Z70, while the Saros 10R takes a negligible cut to 20,000 Pa. The Saros 10 uses the same Reactive AI technology to avoid small obstacles that most of the 2024 Qrevo models did, while the Saros Z70 and 10R have been upgraded to Roborock's StarSight 2.0 technology. StarSight, a combination of dual-light 3D Time-of-Flight technology and AI-powered RGB cameras, is said to lead to more precise mapping and obstacle avoidance, but I didn't find the Saros 10R's obstacle dodging to be particularly better than any obstacle avoidance I've tested out before.

Both the Saros Z70 and Saros 10R mop with dual spinning mopping pads (that's my preference) compared to the Saros 10's singular flat mopping pad.
