Dried-on stain removal is excellent overall, with many sauces, grime patches, and baked-on messes clearing in a few passes or less; a minority needed repeated passes.
Pros: Overall opinion, Steam Cleaning
Cons: Price and Value, Weight
Dried-on stain results were very strong overall, including record-level test praise, with only a comparison review noting the X8 was slightly better.
Pros: Mopping performance, Suction and Airflow
Cons: Price and Value, Battery and Charging
Stain-removal evidence was strong, especially for dried-on or recognized stain tests where the P50 performed above average or triggered focused mopping.
Pros: Mopping performance, AI, Smart, App and Automation
Cons: Noise level, Crevice / Groove Pickup (Hard Floors)
Dried stain removal is one of the strongest areas, with repeated praise for coffee, ketchup, mud, and measured dried-on stain tests.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Dried-on and set-in stain performance is strong, with multiple reviewers saying coffee, jelly, and old furniture stains were cleaned effectively.
Pros: Mopping performance, Overall opinion
Cons: Price and Value, Dock noise
Dried-on or stubborn stain handling was positive, with hot-water washing and repeat passes helping floors come clean.
Pros: Obstacle Avoidance (Robot), Maintenance requirements
Dried-on stain removal was consistently good, with reviewers citing easy cleanup of sticky spills, dried stains, ketchup, coffee, and sauces.
Pros: Adaptive chassis lift, Obstacle Avoidance (Robot)
Cons: Price and Value, Edge and Baseboard Cleaning (Hard Floors)
Dried-on stain removal is a strength in the tests, including maple syrup and dried coffee on hard flooring.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Hair‑Wrap / Tangle Resistance, Floor Drying Time
Dried-on stain removal is mostly strong, handling mud, coffee, and sticky marks well, though ketchup remained a difficult edge case in some tests.
Pros: Mopping performance, Map and Path Efficiency (Robot Vacuums)
Cons: Stuck resistance, Storage footprint and upright-stand stability
Dried-on stain removal was usually strong, especially in tests with coffee, jam, jelly, and soy sauce, though one review saw poor ketchup-stain detection.
Pros: Mopping performance, Overall opinion
Cons: Map and Path Efficiency (Robot Vacuums), Price and Value
Dried-on stain evidence was mixed-to-strong: some tests found below-average stain scores, while others saw strong ketchup, food, and jelly cleanup.
Pros: Mopping performance, Overall opinion
Cons: Low-profile design, Ongoing ownership costs (bags, filters, batteries)
Dried-on stain cleaning ranged from outstanding lab results to needing extra passes on tougher real-world stains.
Pros: Overall opinion, Hair‑Wrap / Tangle Resistance
Cons: Stuck resistance, Emptying and Mess Control
Dried-on stain removal was strong overall, though one reviewer needed several passes or minutes for difficult ketchup, coffee, and sauce tests.
Pros: Self-propel feature, Self-cleaning cycle
Cons: AI, Smart, App and Automation, Heating element
Dried-on stain evidence was mixed: normal grime cleaned well, but ketchup and coffee required manual repeat runs in one test.
Pros: Overall opinion, Mopping performance
Cons: Obstacle Avoidance (Robot), Adaptive chassis lift
Reviewer evidence was mixed on Dried-On Stain Removal, combining useful performance with clear caveats in some tests.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Runtime, Bin and Bag
Dried-on stain evidence is mixed: several reviewers reported excellent stain removal, while stress tests and one German review found missed detection or weaker results.
Pros: Mopping performance, Overall opinion
Cons: Stuck resistance, Solution / Liquid system
Dried-on or sticky stain results were positive in lab testing but more moderate in real kitchen use where traces could remain.
Pros: Price and Value, Overall opinion
Cons: Obstacle Avoidance (Robot), Runtime
Dried or sticky mess removal was good but not flawless, with soda and chair-area sticky spots handled well while syrup remained difficult.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Stain removal is strong overall and can handle dried ketchup, cola and similar messes, but some stubborn spots still need repeat passes or manual cleaning.
Pros: Overall opinion, Mopping performance
Cons: Value-for-money, Price and Value
Dried-on stain results were mixed: muddy, coffee, wine, and sauce tests often cleaned well, but a tough stain and ketchup remained challenging.
Pros: Mopping performance, Overall opinion
Cons: Noise level, Solution / Liquid system
Dried-stain results range from excellent after two passes to ineffective on heavily set stains. Multiple passes are often needed for ketchup, mud, and kitchen residue.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Edge and Baseboard Cleaning (Hard Floors), Noise level
Dried-on stain evidence was mixed, with Vacuum Wars finding below-average stain removal while other reviewers saw strong stain results after adjustments.
Pros: Suction and Airflow, Mopping performance
Cons: Map and Path Efficiency (Robot Vacuums), Runtime
Dried-on and sticky stain performance is mixed, with excellent Vacuum Wars results but weaker jelly, ketchup, and mustard outcomes elsewhere.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Mechanical arm object-moving feature, Overall opinion
Dried-on stains were handled, but not effortlessly; reviewers said they sometimes needed a second pass or many passes before fully clearing.
Pros: Overall opinion, Self-cleaning cycle
Cons: Suitability for heavy-duty use
Dried-on stain removal was only partly successful; mustard mostly came up, but some residue remained.
Pros: Mopping performance, Overall opinion
