Roborock Saros Z70 Robot Vacuum with OmniGrip™ Mechanical Arm

The foldable five-axis arm's gripper is rated for items up to 300 g (0.3 kg) and a built-in weight sensor stops it lifting anything heavier; do not use it on objects over that limit. Roborock lists socks, small towels, crumpled tissues, and slippers as the items it picks up automatically, moving them to drop-off spots you set in the app, such as socks toward the closet or sandals toward the entrance rug, and then cleaning the floor they were covering. You can also drive the arm by hand from the app to pick up and move an item, using the chassis camera and the gripper camera for two viewing angles, and Roborock says more arm features will arrive through OTA updates.

Roborock builds in several protections: an arm switch that stops it extending at all when you do not need it, an emergency stop button that halts the whole robot, a pressure switch and anti-pinch sensor for the arm and its electric hatch, collision sensing that avoids repeated bumps, and a limit on grip force; the gripper can also be forced open to free an item. Roborock's manual still says not to touch any part of the product, especially moving parts, while the arm is extending, gripping, carrying, resetting, or retracting. The arm stays folded inside the body when the robot is idle.

With the arm disabled and mop washing set to every 15 minutes, Roborock rates a charge at about 2 hours 15 minutes of vacuuming and mopping, enough for roughly 180 square meters (about 1,938 sq ft); with the arm enabled and about 10 items tidied during the run, coverage drops to about 150 square meters (about 1,615 sq ft). Each remote pickup without cleaning uses about 1 percent of the battery, and actual results vary with what is on the floor and your wash settings. The 6,400 mAh battery fast-charges in about 2.5 hours, and the robot recharges and resumes except during Do Not Disturb (22:00 to 08:00 by default) or after being placed on the dock by hand.

No plumbing is needed for this configuration. The dock empties the dustbin into a bag that lasts up to 60 days, washes the mops with up to 80 C (176 F) hot water that Roborock rates at 99.99 percent bacteria removal, cleans itself with 80 C hot water, dispenses detergent from a 590 ml reservoir, refills the robot with warm water, and dries the mops and dock base with 55 C (131 F) warm air. You fill the clean tank, empty the dirty tank, top up detergent, and change the bag; always install a bag before refitting the dust container cover.

StarSight Autonomous System 2.0 uses 3D sensing with 21 times the sampling frequency of a spinning LiDAR tower and recognizes 108 types of obstacles out of the box, with VertiBeam lateral sensing for unfolded cables and irregular walls and furniture. You can add up to 50 custom objects, from 10 x 10 cm up to 100 x 100 cm, so the robot recognizes your own items. The robot is 3.14 inches (7.98 cm) tall with no turret, pet recognition stops the main brush and moves it aside near animals, and the app offers pet snaps plus video call and cruise.

Yes. The dock removes the mops before vacuum-only tasks and carpet cleaning, and during mixed runs the mops lift up to 22 mm over carpet; the AdaptiLift chassis crosses double-layer thresholds up to 4 cm (1.57 in). Roborock states the Z70's main brush uses active cutting technology, so it cuts hair as it cleans rather than winding it, and the FlexiArm Riser side brush and mop extend into corners and along edges.

Yes. The built-in Hello Rocky assistant is enabled by default and handles start, pause, dock, and suction or water changes on the robot itself, even without a network, while room commands and arm settings need the Roborock app. Amazon Alexa, Apple Siri, and Google Home are supported, and the robot supports the Matter standard.

The Saros Z70 connects to 2.4 GHz Wi-Fi only; 5 GHz is not supported, so on a dual-band router join the 2.4 GHz network by name. Amazon Alexa, Apple Siri, and Google Home are supported once the robot is linked in the Roborock app; for Alexa, enable the Roborock Plus skill, sign in with your Roborock account, and run Discover Devices. If pairing fails, check the password, allow location and local network permissions for the app, turn off any VPN or cellular data, select your home network rather than the robot's own hotspot, and avoid WEP security or special characters in the network name.

Clean the main brush every 2 weeks and replace it every 6 to 12 months; clean the side brush monthly and replace it every 3 to 6 months; rinse the washable filter every 2 weeks and replace it every 6 to 12 months; wash the mop cloths as needed and replace them every 1 to 3 months, and change the dust bag and rinse the cleaning tray and dirty water tank as needed. The mops are only washed if they were used, and auto-emptying and auto-drying each have to be enabled in the app. Use only cold water in the tank and never disinfectant, and run the robot between 39 and 104 F (4 to 40 C).

Put the dock on a hard, level floor against a wall with at least 0.75 m (2.46 ft) of height, 0.4 m (1.31 ft) of width, and 1.2 m (3.94 ft) of depth kept clear. Roborock's manual lists too many obstacles near the dock as the reason the robot cannot return, so clear them or move the dock to an open area, and wipe the signal window on the dock and the robot's front sensor. If the robot was carried to another room, set it on the dock by hand so it can relocate itself; if it will not charge, check both ends of the power cord. The dock measures 15.0 x 18.7 x 19.21 inches.

Roborock covers new products such as the Saros Z70 with a one-year limited warranty from the purchase date against defects in materials and workmanship. Consumables such as filters, brushes, mop pads, and dust bags are not covered, and normal wear, cosmetic damage, misuse, unauthorized repairs, and commercial use are excluded; a unit repaired or replaced under warranty stays covered for 90 days or the rest of the original term, whichever is longer. Keep your receipt, because without proof of purchase the warranty period runs from three months after the factory ship date. Warranty and technical support run through Roborock US at support-us@roborock.com or 1-855-960-4321 (24/7); RoboticsSelect is an authorized dealer, ships free within the contiguous U.S., and accepts standard returns within 30 days.
