CNET says the coupon promotion runs through September 20 and includes free delivery from Roborock’s store.

The Roborock Saros 20 Flow robot vacuum-and-mop is available for $1,500 with an on-page coupon, according to CNET. That is $200 below the listed original price of about $1,700.

The catch is that shoppers must clip the coupon before adding the robot to their cart. CNET says the promotion ends September 20. The same offer is available through Roborock’s store with free delivery, making the advertised purchase total $1,500 before any costs not covered by the promotion.

CNET describes several features aimed at homes with mixed flooring. Its SpiraFlow 2.0 system uses pressurized self-cleaning and warm water for mopping, while AdaptiLift Traverse 3.0 is designed to handle different surfaces. A HyperForce motor is advertised at 36,000 pascals of suction power, a measurement of air pressure used to describe vacuum strength.

The robot’s slim design may help it reach beneath sofas and tables. CNET also says reactive obstacle-recognition software is intended to help it avoid objects, and that the robot supports Matter, Siri, Google Home and Amazon Alexa for smart-home and voice controls.

These features could matter if you want one premium machine for carpets, hard floors, mopping and connected-home control. But CNET does not independently verify the advertised cleaning, navigation, obstacle-avoidance or suction performance.

At $1,500, this is a premium buy rather than a budget experiment. Check that the coupon applies and review warranty, return and ongoing-price details before ordering; shoppers who can wait may prefer independent testing or a cheaper model.
