A refined Qrevo Pro successor that nails the self-maintenance dock and hair-free brushes, but mid-tier suction keeps it from competing with premium flagships on carpets.
Pet owners should pay attention here. The SGS-certified anti-tangle side brush is not just a spec-sheet bullet — it genuinely solves the problem of hair wrapping around the side spinner that plagues nearly every other robot on the market. Combined with the all-rubber main brush and a full all-in-one dock, the QR 798 is one of the most maintenance-free robots you can buy at any price. The three-stage mop wash cycle is thorough enough that pads stay fresh between washes. The weakness is suction: 10,000Pa is fine for hard floors and low carpet but falls behind the 18,000-20,000Pa crowd on thick rugs. And without a camera, obstacle avoidance is merely acceptable. Best for predominantly hard-floor homes with shedding pets. Heavy carpet users need more power.

Pros & Cons
What We Like
- + All-in-one dock handles emptying, mop washing, drying, and water refill for weeks of hands-off operation
- + SGS-certified anti-tangle side brush eliminates hair wrapping — a real differentiator for pet owners
- + 10,000Pa suction paired with all-rubber main brush delivers solid hard floor and carpet cleaning
- + 180-minute battery covers up to 300 sqm in a single session without recharging
- + Three-stage mop wash cycle (slow pre-wash, rinse, high-speed spin-dry) keeps pads genuinely clean
What Could Be Better
- − 10,000Pa suction trails flagship models that offer 18,000-22,000Pa for deep carpet cleaning
- − No camera-based obstacle avoidance — relies on reactive sensors that miss low-profile objects
- − Heavy at 24 lbs total system weight — not easy to move between floors
