Noise is a positive in the review evidence, with quiet operation and low measured noise that sometimes faded into the background.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Mechanical arm object-moving feature, Overall opinion
Noise is a positive in the review evidence, with quiet operation and low measured noise that sometimes faded into the background.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Mechanical arm object-moving feature, Overall opinion
Noise evidence is limited but positive, with one reviewer calling the X50 Ultra’s mopping action the quietest robovac mop they had tested.
Pros: Adaptive chassis lift, Obstacle Avoidance (Robot)
Cons: Price and Value, Edge and Baseboard Cleaning (Hard Floors)
Noise levels are praised in the dock/drying context, with reviewers saying it is hard to hear.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Hair‑Wrap / Tangle Resistance, Floor Drying Time
Noise feedback was favorable overall; reviewers called it quiet or not very loud relative to its suction power.
Pros: Mopping performance, Overall opinion
Noise feedback is mostly positive, with several reviewers calling the robot quiet, though one measured it louder than most at maximum power.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Cleaning noise is usually praised as quiet or reasonable, but dock and self-washing/auto-empty cycles are louder.
Pros: Mopping performance, Map and Path Efficiency (Robot Vacuums)
Cons: Stuck resistance, Storage footprint and upright-stand stability
Most reviewers found normal operation quiet for a flagship robot, while a few noted dock emptying or some runs were still noticeable.
Pros: Mopping performance, Overall opinion
Cons: Map and Path Efficiency (Robot Vacuums), Price and Value
Noise was consistently treated as a strength, with measured levels below average and real-home testing noting low disruption.
Pros: Overall opinion, Mopping performance
Cons: Obstacle Avoidance (Robot), Adaptive chassis lift
Most comments described quiet operation, but ZDNET noted an unusual whirring sound and Vacuum Wars measured only slightly above average noise.
Pros: Bin and Bag, Overall opinion
Cons: Maintenance requirements, Water tank
The robot itself is usually impressively quiet and can run overnight, but a few owners report intrusive noise after faults or at higher power settings.
Pros: Overall opinion, Mopping performance
Cons: Value-for-money, Price and Value
Reviewer evidence was mixed on Noise level, combining useful performance with clear caveats in some tests.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Runtime, Bin and Bag
Only limited noise evidence appeared, but the hot-air drying noise was not considered loud.
Pros: Overall opinion, Hair‑Wrap / Tangle Resistance
Cons: Stuck resistance, Emptying and Mess Control
Noise is generally acceptable in normal use, with the strongest mode and dock-emptying noted as louder but not dominant concerns.
Pros: Mopping performance, Map and Path Efficiency (Robot Vacuums)
Cons: Obstacle Avoidance (Robot)
Noise feedback was mostly favorable for routine cleaning and dock drying, but one roundup called operation loud and another noted auto-emptying gets loud briefly.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Noise feedback was mixed: one reviewer called it ultra quiet, while another would not nap or watch TV near it at max power.
Pros: Obstacle Avoidance (Robot), Maintenance requirements
Noise was generally acceptable in normal or mopping use, with one review treating louder max output as a reasonable tradeoff.
Pros: Suction and Airflow, Mopping performance
Cons: Map and Path Efficiency (Robot Vacuums), Runtime
Noise impressions are split: some reviewers found the robot or dock loud on high suction and water-fill cycles, while others called it quiet or improved over older models.
Pros: Mopping performance, Overall opinion
Cons: Stuck resistance, Solution / Liquid system
Noise feedback was limited and mixed: one review listed quiet operation as a pro, while another disliked how chatty the robot was.
Pros: Mopping performance, Suction and Airflow
Cons: Price and Value, Battery and Charging
The robot itself can be quiet or reasonable, but dock, mop-cleaning, spot-cleaner, and navigation-struggle noise are repeated drawbacks.
Pros: Mopping performance, Overall opinion
Cons: Price and Value, Dock noise
Noise feedback was split: some reviewers found the P50 unusually loud, while others called it quiet in daily use or quieter than past robot vacuums.
Pros: Mopping performance, AI, Smart, App and Automation
Cons: Noise level, Crevice / Groove Pickup (Hard Floors)
Noise feedback was mixed: one reviewer found it quiet and another said it blended into the background, while several noted it can get fairly loud or louder than rivals at...
Pros: Mopping performance, Overall opinion
Cons: Noise level, Solution / Liquid system
Noise feedback was mixed: one review called it quiet, while others found boost mode loud or measured noticeable operating and dock sounds.
Pros: Price and Value, Overall opinion
Cons: Obstacle Avoidance (Robot), Runtime
Noise drew moderate criticism: reviewers said high suction can get loud or not be as quiet as some rivals, though one test found it only slightly above average.
Pros: Hair‑Wrap / Tangle Resistance, Suction and Airflow
Cons: Noise level
Noise was a recurring tradeoff: reviewers could work near it, but higher suction, rattly wheels, and especially dock suction were criticized.
Pros: Mopping performance, Overall opinion
Cons: Low-profile design, Ongoing ownership costs (bags, filters, batteries)
Noise feedback was mixed: robot mode could be quiet in one test, while other reviewers called the vacuum and dock noisy.
Pros: Overall opinion, Value-for-money
Cons: Obstacle Avoidance (Robot), Mopping performance
The S20 is one of the louder robot cleaners, especially at maximum suction and during mopping. Lower modes help, but work calls, sleep, and quiet rooms can still be affected.
Pros: Mopping performance, Obstacle Avoidance (Robot)
Cons: Edge and Baseboard Cleaning (Hard Floors), Noise level
