Robot Vacuums Are Growing Arms And They’re Starting to Move Things Around the Home

Robot vacuum cleaners have spent years getting better at one basic task: navigating around the home and cleaning the floor without human help.

But the newest generation is beginning to do something fundamentally different.

Instead of simply detecting an obstacle and driving around it, some robot vacuums are now being equipped with mechanical arms that can reach out, manipulate objects and clear parts of the floor.

One of the clearest examples is the Roborock Saros Z70, which uses a foldable five-axis mechanical arm called OmniGrip. Roborock says the arm can move selected objects out of the robot’s path and help the machine reach areas that would otherwise remain blocked.

This represents an important shift in the way robotic home appliances are being designed.

From avoiding obstacles to handling them

Traditional robot vacuums are built around a simple principle: see an obstacle, avoid it.

That works well for furniture, walls and larger objects. But everyday floors are rarely completely clear.

A sock, slipper, toy, cable or small household object can prevent a robot from reaching a particular section of the floor. Conventional machines usually have only two choices — go around the object or stop.

A robotic arm introduces a third option.

The robot can identify an object, position itself appropriately and use an articulated mechanism to move it before continuing its cleaning route.

Roborock’s Saros Z70 is designed around precisely this concept. Its five-axis arm folds into the robot when not required and can extend when the machine needs to manipulate an object.

That may sound like a small improvement, but it changes the underlying philosophy of autonomous cleaning.

The machine is no longer simply navigating through an environment.

It is beginning to interact with the environment.

How does the robotic arm work?

The arm is essentially a miniature robotic manipulation system integrated into a mobile vacuum platform.

Multiple joints allow the arm to change its position and orientation. A gripper at the end can interact with selected objects.

But an arm alone is not enough.

The robot also needs to determine what it is looking at, where the object is located, whether it can safely move it and where it should place it.

That requires a combination of cameras, sensors, mapping technology, motion planning and software.

Roborock describes the Z70’s system as an AI-powered mechanical arm capable of identifying and manipulating selected objects. The company combines it with its autonomous navigation and obstacle-recognition systems.

In other words, the arm is only the physical part of a much larger system.

The real technological challenge is coordinating perception, decision-making and movement.

Why this is different from a normal robot vacuum

A conventional robot vacuum operates primarily in two dimensions.

It moves across the floor, maps rooms and adjusts its route according to what it detects.

An arm adds another dimension.

The machine can now reach upward from its body and interact with objects located around it. That creates possibilities that were previously difficult for a low-profile floor-cleaning robot.

Dreame has also been developing arm-equipped robot vacuums. Its 2026-generation systems use extending bionic arms designed to reach into narrower spaces and extend cleaning coverage. Dreame says one of its newer designs can extend a mop pad by up to 18 centimetres into narrow areas.

The broader direction is clear: robot vacuums are increasingly being designed not just to move through rooms, but to perform physical actions inside them.

The robot still has limitations

The technology is impressive, but it does not mean a robot vacuum has suddenly become a fully autonomous household servant.

There are important limitations.

A mechanical arm has to operate within limits of weight, reach, grip and object shape. A robot may be able to move a lightweight slipper but struggle with a heavier or irregularly shaped object.

It also needs to understand whether moving an object is safe.

A cable, glass object, liquid container or fragile item presents a very different problem from a sock lying on a hard floor.

This is why current systems are better understood as specialized robotic manipulation tools rather than general-purpose household robots.

Independent testing of the Saros Z70 has also found that the arm adds significant capability, while its usefulness depends on the specific objects and situations encountered in a home.

The bigger breakthrough may be AI

The mechanical arm is the part people notice first.

But the more significant development could be the intelligence behind it.

For a robot to manipulate an object autonomously, it has to answer several questions almost instantly:

What is the object?

Where is it?

Can I reach it?

Can I safely grab it?

Where should I move it?

Will moving it allow me to clean the area underneath?

That is fundamentally different from simply recognizing an obstacle and steering around it.

It requires robotic perception and motion planning to work together.

As these systems improve, the same architecture could potentially be adapted for tasks beyond vacuuming.

From cleaning robot to household robot

This is where the technology becomes particularly interesting.

A vacuum cleaner with a small robotic arm is still primarily a cleaning appliance.

But the underlying technologies — mobile navigation, object recognition, manipulation and autonomous decision-making — are also fundamental components of more general-purpose robots.

The development of arm-equipped vacuum cleaners therefore provides a relatively controlled environment for testing these technologies in ordinary homes.

A floor is predictable.

The objects are relatively small.

The robot’s movements can be constrained.

And the task has a clear objective: clean the floor.

That makes robotic vacuum cleaners an interesting platform for introducing physical manipulation into consumer robotics.

Other companies are exploring the same direction

Roborock is not alone.

Dreame has demonstrated its Cyber10 Ultra concept with an extendable robotic arm and claw designed to handle objects and perform additional tasks. The company confirmed at CES 2026 that the arm-equipped system was moving toward commercial availability.

Dreame has also continued developing bionic-arm systems for robot vacuums, including designs intended to extend cleaning components into difficult-to-reach areas.

This suggests that robotic arms may become one of the next major areas of competition in the premium robot-vacuum market.

The competition is no longer only about suction power, battery life or mopping.

It is increasingly about what the robot can physically do.

What could come next?

Today’s robotic arms are relatively limited.

Future versions could become more capable as sensors, motors, batteries and AI systems improve.

A future home robot could potentially recognize different categories of objects, organize clutter, manipulate household items and use different tools for different cleaning tasks.

Instead of a robot that simply vacuums underneath a table, imagine one that recognizes objects blocking the area, moves them aside, cleans the floor and then returns the objects to an appropriate location.

That would require considerably more advanced perception and reasoning than today’s systems.

But the basic technological building blocks are already appearing in consumer products.

The real meaning of the robotic arm

The most important part of this development isn’t that a vacuum cleaner can pick up a slipper.

It is that consumer robots are beginning to cross a technological boundary.

For years, household robots were primarily mobile machines. They could move around an environment, map it and avoid obstacles.

Now, some are beginning to become manipulative machines — systems capable of physically changing their surroundings.

That distinction could prove important.

The robot vacuum may have started as a machine that replaced one simple household chore. With robotic arms, it is becoming a testbed for a much broader idea: machines that can see, move, decide and physically interact with the world around them.

The future of household robotics may therefore not be about building a better vacuum cleaner alone.

It may be about turning the vacuum cleaner into the first generation of a much more capable home robot.
