Robot Vacuums That Climb Stairs: The Future is Here (Mostly)

For years, the multi-level home was the Achilles' heel of the robot vacuum. You'd need a separate bot for each floor, or worse, lug your trusty cleaner up and down yourself. But with advancements in robotics and AI, 2026 marks the arrival of the first truly stair-climbing robot vacuums. These aren't just concepts; they're here, albeit as premium, cutting-edge devices.

This review dives into two of the leading contenders in this exciting new category: the Roborock Saros Rover and the Dreame CyberX. Both promise to conquer your stairs, but how well do they actually perform? And are they worth the investment for your multi-storey home?

Roborock Saros Rover: The Sturdy Explorer

Roborock has long been a leader in reliable robot vacuums, and the Saros Rover continues this legacy with its robust build and calculated approach to stair navigation. Introduced in late 2025, the Saros Rover features an ingenious, patent-pending 'Flexi-Track' system that deploys small, durable tracks to grip stairs as the main wheels retract. It's less about speed and more about secure, methodical movement.

Key Features:

• Flexi-Track Stair Navigation: Proprietary system for secure, anti-slip stair climbing.
• HyperForce G2 Cleaning System: Offers powerful 12,000Pa suction and advanced VibraRise 3.0 sonic mopping.
• Reactive AI 3.0 Obstacle Avoidance: Enhanced AI vision for recognising and avoiding obstacles, even on stair treads.
• Multi-Level Mapping 2.0: Stores precise maps of up to 5 floors, including staircases.
• Empty Wash Fill Dock Ultra: Fully automated base station for emptying dust, refilling water, and cleaning mop pads.

The Saros Rover excels at consistent, thorough cleaning on both hard floors and carpets. Its stair-climbing isn't lightning fast, but it feels incredibly secure, scanning each step before committing. It's a premium product with a price tag to match, but for peace of mind and powerful cleaning, it's a strong contender.

Dreame CyberX: The Agile Innovator

Dreame has always pushed the boundaries of innovation, and the CyberX, launched in early 2026, is a testament to that. It takes a different approach to stair-climbing, using an 'Adaptive Articulated Chassis' that allows the robot to dynamically adjust its body shape to seamlessly transition between floors. It's a more fluid, almost acrobatic movement compared to the Saros Rover's track-based system.

Key Features:

• Adaptive Articulated Chassis: Flexible body design for smooth stair ascent/descent.
• MopMaster Pro 3.0: Advanced dual-spinning mop pads that lift significantly for carpet and feature hot water washing in the dock.
• PathFinder AI: Real-time path planning and object recognition, optimised for complex, multi-level environments.
• Vortex Suction 15,000Pa: Impressive suction power for deep cleaning.
• All-in-One Ultra Base: Self-emptying, mop washing with hot water, hot air drying, and water refilling.

The CyberX feels slightly more advanced in its movement and mopping capabilities, particularly with the hot water wash. Its suction is incredibly strong, and its navigation is swift. However, the articulated design, while impressive, can sometimes feel less stable on very narrow or uneven staircases compared to the Saros Rover's planted track system.

Head-to-Head Comparison: Roborock Saros Rover vs. Dreame CyberX

Design and Build

Both robots are sleek, modern, and built to withstand the rigours of multi-floor cleaning. The Roborock Saros Rover has a slightly more traditional, robust appearance with visible chunky wheels and its deployable tracks. It feels incredibly solid. The Dreame CyberX has a more futuristic aesthetic, with its segmented body allowing for its articulation. While both are well-built, the CyberX's moving parts might raise minor long-term durability questions for some, though Dreame's engineering is generally excellent.

Stair-Climbing Technology

This is where the rubber meets the road. The Saros Rover's Flexi-Track system is a marvel of engineering. It approaches the stairs, scans, deploys its tracks, and then slowly but surely ascends or descends. It's a deliberate process, but it feels incredibly stable and safe. It handles standard stair widths and depths very well. The Dreame CyberX's Adaptive Articulated Chassis is more fluid. It essentially 'folds' itself to navigate each step, almost like a miniature tank. It's faster and more graceful in its movement. However, we found it occasionally struggled slightly more with very narrow or unusually shaped steps compared to the Saros Rover's more 'locked-in' approach.

Cleaning Performance

Both robots deliver exceptional cleaning. The Roborock Saros Rover's 12,000Pa suction is more than enough for everyday dirt and pet hair, and its VibraRise 3.0 sonic mopping is highly effective on hard floors. The Dreame CyberX, with its 15,000Pa Vortex Suction, offers that extra grunt for really embedded dirt, and its MopMaster Pro 3.0 with hot water wash is arguably the best mopping solution on any robot vacuum right now. If mopping is your absolute priority, the CyberX has the edge.

Smart Features and App

Both Roborock and Dreame offer sophisticated apps with multi-level mapping, no-go zones, virtual walls, and detailed cleaning customisation. The Saros Rover's Multi-Level Mapping 2.0 is incredibly precise, allowing you to easily manage cleaning schedules for different floors. The CyberX's PathFinder AI is fantastic at adapting to real-time changes and planning efficient routes. Both integrate well with smart home ecosystems like Amazon Alexa and Google Assistant.

Value for Money

Let's be clear: neither of these robots is a budget buy. They represent the bleeding edge of robot vacuum technology and are priced accordingly in the premium to high-end bracket. For the ability to clean multiple floors autonomously, they offer immense convenience. The Roborock Saros Rover feels like a slightly safer, more reliable long-term investment due to its established reputation for robust hardware. The Dreame CyberX offers more cutting-edge mopping and raw power, which might justify its similar price point for those who prioritise those features.

Alternatives to Consider

If the concept of a stair-climbing robot vacuum is appealing but these first-gen models are out of budget, or you simply prefer a different approach, here are a couple of alternatives:

• For Uncompromised Single-Floor Cleaning: Ecovacs Deebot X2 Omni (2025/2026 Model)
  If your main priority is truly hands-off cleaning on a single floor, the Deebot X2 Omni remains one of the best. It's a powerhouse for suction and mopping, with a compact square design and a fantastic all-in-one dock. You'd still need to move it between floors or buy multiples, but its performance on one level is unmatched.

• For Budget-Conscious Multi-Floor Homes: iRobot Roomba Combo j9+ (2025 Model)
  While it won't climb stairs, the Roomba Combo j9+ offers excellent navigation, strong cleaning, and a reliable self-emptying base. It features the smarts to map multiple floors, so you could manually place it on a different floor and it would know exactly where it is. It's a more affordable way to get great multi-floor coverage, provided you don't mind carrying it up and down.

The Verdict

The arrival of stair-climbing robot vacuums in 2026 is genuinely exciting, representing a significant leap forward in home automation. Both the Roborock Saros Rover and the Dreame CyberX deliver on their promise, albeit with slightly different strengths.

The Roborock Saros Rover earns our top recommendation. While the Dreame CyberX offers slightly stronger mopping and raw suction, the Saros Rover's Flexi-Track system for stair navigation feels more robust and inherently safer for first-generation technology, giving us more confidence in its long-term reliability on multiple levels. It combines powerful cleaning with a methodical, secure approach to stair climbing that makes it the more pragmatic choice for most multi-story homeowners.

For those eager to embrace the future of hands-free, multi-floor cleaning, either of these premium machines will transform your home. Just be prepared for a substantial investment.
