When it comes to robot vacuums in 2025, Roborock stands out as my top choice. This brand has consistently delivered high-quality, reliable, and powerful vacuum solutions for years, earning spots in numerous top picks for robot vacuums and mops. At CES 2025, there were many exciting developments in smart home technology, but the Roborock Saros Z70 truly captured my attention. Featuring a robotic arm designed to pick up small items in its path, it represents one of the most innovative home cleaning devices I’ve encountered, and I’m eager to see how it influences the market.
While robot vacuums are meant to be independent helpers that maintain clean floors with minimal involvement from us, this is often not the reality. Many struggle with inadequate sensors that lead to getting stuck, weak suction that fails to handle more stubborn debris, or poor navigation that leaves them entangled in cords or other obstacles. As a result, some devices do not deliver the expected hands-free experience.
That said, Roborock has seemingly perfected the fundamentals with its current Qrevo Curv model, which boasts impressive suction capabilities, outstanding mapping technology, and a self-cleaning dock so efficient I often forget it’s even operating in my home.

With the basics in check, Roborock is now shifting its focus towards enhancing the versatility of smart home products. A perfect example of this initiative is the robotic arm, which is intended to clear obstacles it encounters. It’s important to note that the Saros Z70 is not capable of picking up larger items like gym shoes or clothes. Instead, its current lifting capacity is limited to 300 grams. Should it attempt to lift something heavier, its sensors will detect the weight and carefully lower the object back down.
Currently, the robotic arm exhibits a slower reaction time, as demonstrated during the CES 2025 presentation, which showcased a few missed grabs and generally sluggish actions. However, this innovation is one of the first significant advancements in the robot vacuum market, making it an exciting development to follow.
Before the advent of robotic arms, self-cleaning docks were the standout feature, and now they are common in nearly every high-end device. They perform exceptionally well, alleviating concerns about mold or unpleasant odors. The introduction of a robotic arm, no matter how gradual its functionality, could pave the way for transformative advancements in the near future. Imagine a world where robot vacuums seamlessly manage all of our messes, with no worries about picking up toys or clothes prior to cleaning cycles. That could lead to a thorough clean, even with clutter left behind.
Roborock has a proven track record when it comes to crafting top-notch robot vacuums. I have always been impressed with their prior models, and if there’s any brand capable of successfully integrating a robotic arm into a vacuum cleaner, it’s Roborock. I look forward to seeing how the Saros Z70 evolves, and I hope this is merely the beginning of more groundbreaking developments from the company.
