Narwal Freo X Plus
Score: 82/100
Roborock Qrevo Series
Score: 85/100Rankings

The Roborock QV 35A delivers 8000 Pa suction, a 180-minute runtime, and an all-in-one dock that auto-empties dust and refills water for continuous vacuum-mop performance. Its heavyweight design and large dock make it less suited for tight spaces. Perfect for large homes with pets that need powerful, hands-free cleaning.

The Narwal Freo X Plus combines 7800 Pa suction with a zero-tangle brush and a self-emptying base that can store up to seven weeks of dust, making it a strong performer on hard floors and carpets. Its main drawbacks are the absence of a rotating mop and limited premium auto-empty features. Ideal for pet owners and small-to-medium homes that prioritize quiet, low-maintenance vacuuming.

Professional commentary is scarce because the QV 35A launched only in early 2025, but the available product pages and brief editor notes emphasize its 8000 Pa suction, extensive auto-empty dock, and precise LiDAR navigation as standout upgrades over previous models. The lack of third-party testing leaves some performance claims unverified.
Early user feedback is overwhelmingly positive, highlighting the robot's strong suction, pet-hair handling, and the convenience of the self-cleaning dock. Reviewers note the machine feels quiet and runs long enough to cover large homes, with no major complaints surfacing yet.
