How well does the Roborock Saros Z70 clean floors?

The Saros Z70 offers powerful cleaning with 22,000 Pa of HyperForce suction, which is higher than most smart vacuums on the market. It also features extendable brush and mop heads to effectively clean corners, and the mop pads are washed with hot water at 80 degrees Celsius to prevent stains and sterilization.

What is the unique OmniGrip mechanical arm capable of?

The OmniGrip mechanical arm is a unique feature that allows the vacuum to pick up items that cannot be sucked up by the vacuum's main suction. It can grab things like napkins, tissues, socks, or even slippers, with a maximum weight capacity of about 300 grams (just over half a pound). The arm can be customized in the app to sort these items into a designated bin.

How does the Roborock Saros Z70 navigate and avoid obstacles?

The vacuum uses the Starite Autonomous System 2.0, which incorporates next-generation 3D sensing technology with dual Time of Flight sensors on both the front and back. This system allows it to not only track existing layouts but also adapt to new furniture or forgotten items on the floor, providing excellent obstacle avoidance and mapping. Its low 3.14-inch clearance also allows it to fit under most furniture.

Does the Roborock Saros Z70 handle pet and human hair well?

Yes, the Saros Z70 features a dual anti-tangle brush system designed to prevent hair issues. The reviewer, who lives with three cats and his wife, reported no tangling problems with cat or human hair during a month and a half of use. The strong suction power ensures hair is effectively collected into the bin.

Is the robotic arm feature fully developed or does it have limitations?

While the robotic arm is a highly unique and beneficial feature, the reviewer notes that it is still improving with time and is not yet "perfect." It's considered an "icing on the cake" feature that enhances the overall experience rather than being its primary flawless function. Users should expect it to get better with future updates.

About this source

This review covers the Roborock Saros Z70 smart vacuum, focusing on its unique features such as a robotic arm for debris pickup and powerful suction. The reviewer discusses its mapping system, obstacle avoidance, cleaning capabilities for various surfaces, and overall performance after a month and a half of use.

Review notes

This smart vacuum is a highly recommended choice for its exceptional cleaning power and advanced navigation capabilities. It boasts an impressive 22,000 Pa HyperForce suction system and its unique OmniGrip mechanical arm can pick up items like socks and slippers weighing up to 300 grams. While the robotic arm adds unique functionality, the reviewer notes it is still improving and not yet "perfect." If you prioritize powerful cleaning, intelligent obstacle avoidance, and are intrigued by the potential of a robotic arm to handle larger debris, this vacuum is an excellent fit. However, if you expect flawless performance from the robotic arm right out of the box, you might find it has room for improvement.
