Qrevo Curv by Roborock & J15 Max Ultra by Eureka

Roborock Qrevo Curv delivers effective cleaning on mixed floors and pet hair with 19,000 Pa suction, mop cleaning, and problem area targeting, enhanced by quieter 61.5 dB operation. Eureka J15 Max Ultra counters with higher 22,000 Pa suction, roller brush lifting, and superior debris handling on carpets via large sweeps that prevent clogs. In real-world scenarios, Eureka edges out for spill management and heavy debris, while Qrevo Curv excels in consistent hard floor and pet hair pickup.

Qrevo Curv employs LiDAR, RGB camera, and 3D structured light for precise AI obstacle avoidance and 40 mm threshold crossing, outperforming in refined maneuverability. Eureka J15 Max Ultra uses LDS LiDAR, Full HD vision, and ultrasonic sensors with SLAM for spill detection, but past Eureka models scored lower in obstacle avoidance tests. Qrevo Curv provides more reliable mapping in complex homes, while Eureka improves on liquid and reflective surface navigation.

Roborock Qrevo Curv offers a typical 3-5 year lithium-ion battery service life, suitable for standard sessions at 0.3 m/s speed. Eureka J15 Max Ultra features a larger 6400 mAh battery supporting up to 240 minutes runtime, though with shorter 2-3 year service life. Eureka holds advantage for larger areas requiring extended cleaning without recharge.

Qrevo Curv relies on proprietary OS with app control and AI automation for seamless operation. Eureka J15 Max Ultra expands with mobile app, voice control via Alexa/Google Home, physical buttons, and AI-enhanced firmware for autonomous spill response. Eureka provides broader smart home integration, while both deliver reliable app-based mapping and scheduling.

Qrevo Curv's slimmer 7.98 cm height, 3.9 kg weight, and 0.32 l dustbin facilitate easy maintenance and under-furniture cleaning, with auto height adjustment. Eureka J15 Max Ultra's 10.9 cm height and 4.5 kg build include self-cleaning base and brush lift, but larger size reduces clearance. Qrevo Curv suits tighter spaces, while Eureka prioritizes durable spill-resistant components.

Qrevo Curv fits homes with high thresholds, pet hair, and mixed floors, leveraging compact design and cliff/bump sensors. Eureka J15 Max Ultra targets pet owners and families with spill handling, ultrasonic detection, and high suction for everyday messes. Both handle residential cleaning effectively, with choices depending on floor obstacles versus liquid spills.

Qrevo Curv includes obstacle detection, collision avoidance, child lock, and LED for dark areas. Eureka J15 Max Ultra adds cliff detection, anti-collision sensors, child lock, and automatic brush lift on liquids. Eureka's spill-specific safety gives it an edge in wet environments.

Qrevo Curv manages pet hair well across mixed floors with strong suction and mop lifting, ideal for dry debris in pet-heavy homes. Eureka J15 Max Ultra excels in pet scenarios via high suction, spill detection, and brush lift to avoid tracking messes. For pet owners prioritizing hair and occasional spills, Eureka J15 Max Ultra offers the better overall fit.

Qrevo Curv navigates efficiently with precise LiDAR but standard battery limits extended sessions in vast spaces. Eureka J15 Max Ultra's 6400 mAh battery and 240-minute runtime support larger areas without frequent recharges. Eureka J15 Max Ultra is preferable for large homes needing prolonged cleaning cycles.
