Reviewers consistently praised suction, saying it outperformed the j7+, made a real-world difference, and was powerful enough to clear typical debris.
Pros: Pet-Ready Features, Tool-change simplicity
Cons: Stair Cleaning, Build quality and durability
Reviewers consistently found usable suction for routine debris, with strong praise in one long-term review and test evidence that pickup was reasonable over time.
Pros: Energy efficiency (kWh), Packaging quality
Cons: Hair‑Wrap / Tangle Resistance, Stuck resistance
Reviewers consistently rated vacuum pickup highly, citing strong suction, good vacuuming results, a 90/100 deep-cleaning score, and carpet suction that helped the rollers clean effectively.
Pros: Hair‑Wrap / Tangle Resistance, Overall durability/longevity
Cons: Mop lifting system, Cord management
Positive review evidence says the robot vacuums with strong suction and can feel comparable to premium bots, though suction concerns appear elsewhere under price and floor-specific pickup.
Pros: Hair Pickup — Hard Floors, Carpet — Medium-Pile Pickup
Cons: Heating element, Kid-friendliness
Reviewers generally found vacuum pickup strong, with several praising real-world vacuuming even though one noted only standard-level suction.
Pros: Pet-Ready Features, Ease of use
Cons: Self-cleaning cycle, Dock noise
Reviewers generally found vacuuming strong for everyday dust, dirt, and mixed flooring, though suction and crevice power were criticized by some tests.
Pros: Mop lifting system, Area Rug Handling
Cons: Bin and Bag, Self-cleaning cycle
Suction and dirt pickup are broadly good for the price, although reviewers note it still lacks the power for deeper carpet cleaning.
Pros: Ease of use, Accessories and Tools
Cons: Innovation compared to competitors, Area Rug Handling
