10 Best Robot Vacuum For Stairs 2025 in the United States

The Roborock Q7 M5+ is a strong contender if you need a robot vacuum that can handle stairs safely and clean multiple floors efficiently. It has a built-in cliff detection system, which helps prevent it from falling down stairs, making it suitable for homes with different levels. Its PreciSense LiDAR navigation creates precise real-time maps, allowing it to plan the best cleaning routes and remember multiple floors.

With a powerful 10,000Pa suction, it effectively picks up pet hair, dust, and dirt, even deep in carpets. What’s more, the dual anti-tangle brush design helps reduce hair wrapping, so it can clean longer without interruptions—a big plus for pet owners. The vacuum also combines vacuuming and mopping, with adjustable water flow to customize cleaning according to your floor type. Its dustbin is replaced by a 2.7L sealed dust bag in the self-emptying base, which can hold up to 7 weeks of debris, reducing the hassle of frequent emptying.

The Roborock app lets you control the vacuum remotely, schedule cleanings, set no-go zones, and track its progress, offering convenience especially if you want hands-free operation. The vacuum is somewhat tall and wide, so it might struggle in very tight spaces or under low furniture. Also, the app only works on 2.4GHz Wi-Fi, which could be a limitation if your home uses 5GHz networks exclusively. The Roborock Q7 M5+ provides thorough cleaning across stair-safe multi-floor homes, especially benefiting pet owners who want a low-maintenance, powerful robot vacuum with smart controls.

The Roborock Qrevo CurvX stands out as a powerful and smart robot vacuum designed with advanced features that make it a solid choice for homes with stairs. Its cliff detection is integrated through the Reactive AI Obstacle Recognition and precise LiDAR navigation, which help it avoid drops like stairs and other hazards. The suction power is very strong at 22,000Pa, making it effective at deep cleaning carpets, pet hair, and debris that often accumulate near stair edges. The ultra-slim 7.98 cm design allows it to reach under low furniture, but the overall size and 42.4-pound weight are relatively large, which might affect portability between floors if you need to move it manually. Battery life offers about 150 minutes, sufficient for most medium to large homes, but heavy multi-floor use might require more frequent recharges.

The AdaptiLift Chassis is an innovative feature that adjusts height to help it cross thresholds up to 4 cm, useful for moving between rooms but not for actual stair climbing. Multi-floor mapping and smart app control provide tailored cleaning schedules and no-go zones, including setting boundaries near stairs for safety. The multifunctional dock adds convenience with automatic mop washing and drying, dust emptying, and tank refilling, reducing maintenance effort. Pet-friendly features like two-way voice and real-time video interaction add a unique touch for pet owners.

While the robot excels on flat surfaces and floor transitions, it cannot physically climb stairs and must be carried between floors. Also, its advanced technology may come at a higher price point. The Roborock Qrevo CurvX is ideal for users who want a thorough, smart cleaning robot that safely avoids stair edges and manages multiple floors with smart mapping and strong suction, but it requires manual handling for stair changes.

The Shark AI Ultra Voice Control Robot Vacuum offers several impressive features catering to various cleaning needs. It boasts powerful suction, making it effective on both carpet and hard floors, which is ideal for homes with pets. The Matrix Clean navigation ensures thorough cleaning by taking multiple passes over debris, and the self-cleaning brushroll efficiently handles hair and dirt while preventing tangles.

An exceptional feature is the self-emptying base that can hold up to 60 days of dirt, reducing maintenance efforts. Additionally, the robot's 360° LiDAR vision provides precise home mapping, allowing it to navigate and clean systematically, even in changing environments. The voice control via Alexa or Google Assistant adds convenience for hands-free operation, and the recharge and resume feature ensures extended cleaning sessions, with up to 120 minutes of battery life per charge.

The size and design are relatively bulky, which might be a limitation in tight spaces. Despite these considerations, the Shark AI Ultra is a robust choice for pet owners and those seeking an efficient, low-maintenance cleaning solution with advanced mapping and smart features.
