The liquid system is praised for efficient water use, reduced smearing, and better cleaning-solution results than water alone.
Pros: Wool carpet compatibility, Hair‑Wrap / Tangle Resistance
Cons: Suitability for heavy-duty use, Edge‑Following Accuracy (Robot)
Liquid-system evidence was positive, with reviewers praising detergent support and a water-hookup experience that made cleaning more automated.
Pros: Hair Pickup — Carpets, Noise level
Cons: Crevice / Groove Pickup (Hard Floors), Edge‑Following Accuracy (Robot)
The cleaning-solution system was liked for automatic dispensing and included detergent, adding convenience to mopping maintenance.
Pros: Hair Pickup — Hard Floors, Corner Cleaning (Robot)
Cons: Carpet — High-Pile Pickup, Support and Reliability
The detergent and liquid system reduced manual mixing, but still required periodic refills and dirty-water attention.
Pros: Tool-change simplicity, Battery and Charging
Cons: Cord management, Support and Reliability
The liquid and solution system was praised for automatic detergent mixing, adjustable water flow, and dedicated solution hardware.
Pros: Overall cleaning convenience, Streaking / Residue
Cons: Suitability for small spaces, Dock noise
The solution and liquid system was mostly praised for automatic dispensing and low solution use, with one small sample-size caveat.
Pros: Hair‑Wrap / Tangle Resistance, Aesthetic design and finish
Cons: Dirty water sensor, Scratch resistance
The solution system was useful and automated, but reviewers noted that solution may be sold separately.
Pros: Packaging quality, Dried-On Stain Removal
Cons: Overall durability/longevity, Support and Reliability
The detergent system was viewed as useful for dirty floors, though not all reviewers tested the refill solution.
Pros: Innovation compared to competitors, Under-Furniture Pickup
Cons: Tool-change simplicity, Build quality and durability
The liquid and detergent system is viewed positively for hot-water detergent cleaning and a fresh scent, with some water-tank caveats elsewhere.
Pros: Noise level, Maneuverability and Handling
Cons: Clogging and debris prevention, Bin and Bag
Liquid-system feedback was mixed, with praise for low refill frequency and fluid flexibility but complaints about a smaller cleaning-fluid tank.
Pros: Carpet — Medium-Pile Pickup, Heating element
Cons: Clogging and debris prevention, Hair-removal channel issues
Reviewer evidence was mixed on Solution / Liquid system, combining useful performance with clear caveats in some tests.
Pros: Hair‑Wrap / Tangle Resistance, Versatility
Cons: Stair Cleaning, Clogging and debris prevention
The liquid system drew mixed feedback: separate water output and smart water supply were praised, but missing automatic solution dispensing, reservoir filling, and minor leakage were drawbacks.
Pros: Pet-Ready Features, Assembly and Setup
Cons: Dock noise, Reverse cleaning performance
The liquid/solution system was mixed-to-positive, with dual-solution control praised but low water use criticized.
Pros: Obstacle Avoidance (Robot), Carpet — Medium-Pile Pickup
Cons: Dirty water sensor, Runtime
The liquid system is mixed: reviewers liked automated water handling and self-washing, but repeatedly noted the lack of detergent dispensing.
Pros: Innovation compared to competitors, Hard Floor — Large Debris Intake
Cons: Emptying and Mess Control, Cord management
The dual liquid system was useful for targeted cleaning in some reviews, but several criticized separate solutions as expensive, a hassle, or not included.
Pros: Pet-Ready Features, Suitability for heavy-duty use
Cons: Value-for-money, Area Rug Handling
The liquid system was seen as basic because it relies on wet mop pads rather than spraying or onboard dirty-water handling.
Pros: Overall cleaning convenience, Storage footprint and upright-stand stability
Cons: Kid-friendliness, Obstacle Avoidance (Robot)
Liquid-system feedback was mixed: self-washing and constant clean water were praised, but several reviewers criticized the lack of detergent or cleaning-solution dispensing.
Pros: Suction and Airflow, Filtration / Dust Containment
Cons: Water tank, Versatility
The liquid system was criticized in one review because the small onboard tank needed regular refilling.
Pros: Ongoing ownership costs (bags, filters
Cons: Floor Drying Time, Odor control
The liquid system was a repeated weakness because reviewers wanted automatic solution dispensing instead of manual mixing.
Pros: Clogging and debris prevention, Floorhead design
Cons: Adaptive chassis lift, Solution / Liquid system
The liquid system was limited by the lack of adjustable water-level control.
Pros: Accessories and Tools, Streaking / Residue
Cons: Convertible handheld design, Clogging and debris prevention
The liquid/detergent system is useful but one reviewer found the detergent door hard to open.
Pros: Hair‑Wrap / Tangle Resistance, Versatility
Cons: Hair-removal channel issues, Clogging and debris prevention
The liquid system drew a clear limitation because there was no solution compartment or automatic dispensing.
Pros: Kid-friendliness, Reverse cleaning performance
Cons: Solution / Liquid system, Low-profile design
