Noise drew strong praise in the hands-on review that described the PencilWash as very quiet and usable without disturbing others.
Pros: Weight, Low-profile design
Cons: Overall opinion, Price and Value
Noise drew strong praise in the hands-on review that described the PencilWash as very quiet and usable without disturbing others.
Pros: Weight, Low-profile design
Cons: Overall opinion, Price and Value
Cleaning itself is notably quiet because there is no large suction motor. The loud part comes later on the dock rather than while moving across the floor.
Pros: Self-cleaning cycle, Overall opinion
Cons: Emptying and Mess Control, Price and Value
The robot itself is notably quiet for its power and can often run in the same room without disturbance. The brief self-emptying and water-pumping cycles are much louder.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Cons: Price and Value, Stuck resistance
The robot is unusually quiet during normal cleaning, often leaving pets undisturbed and allowing early-morning or late-night runs. Maximum suction can still be heard, but it rarely dominates a room.
Pros: Mopping performance, Overall opinion
Cons: Edge and Baseboard Cleaning (Hard Floors), Price and Value
Normal robot cleaning is generally acceptable to quiet, with one test citing about 58 dB and another calling it average on Normal mode. The robot itself is much less intrusive...
Pros: Suction and Airflow, Obstacle Avoidance (Robot)
Cons: Streaking / Residue, Solution / Liquid system
Reviewers generally found standard cleaning quiet or manageable, with louder moments on high suction or during dock activity.
Pros: Overall opinion, Suction and Airflow
Noise impressions were mostly favorable for the power level, especially dock noise, though one review still called the robot noisy in some configurations.
Pros: Overall opinion, Obstacle Avoidance (Robot)
Cons: Map and Path Efficiency (Robot Vacuums), Heating element
Noise impressions ranged from very quiet in one home to among the loudest robovacs in another, with dock self-emptying and mop-prep cycles drawing the most criticism.
Pros: Overall opinion, Mopping performance
Cons: Price and Value, AI, Smart, App and Automation
Noise feedback was mostly positive, with reviewers calling it relatively quiet, though one noted it could still be a little loud and dock emptying was not quiet.
Pros: Overall opinion, AI, Smart, App and Automation
Cons: Obstacle Avoidance (Robot), Hair‑Wrap / Tangle Resistance
Noise is context-dependent: one reviewer found higher power louder and rattly, another noted roller noise, while the Italian review praised restrained cleaning noise.
Pros: Dried-On Stain Removal, Mop lifting system
Cons: Emptying and Mess Control
The vacuum is clearly audible at higher power, but its running noise is not unusually harsh for a cordless model. The auto-empty burst is brief.
Pros: AI, Smart, App and Automation, Emptying and Mess Control
Cons: Dock noise, Battery and Charging
Noise was acceptable for scheduled cleaning in some homes, but reviewers noted louder maximum suction and dock/drying sounds.
Pros: Overall opinion, Mopping performance
Cons: Obstacle Avoidance (Robot), Dried-On Stain Removal
The robot is acceptable on lower settings but becomes noticeably loud at maximum suction. Buyers sensitive to noise will likely prefer scheduled daytime runs or reduced power.
Pros: Overall opinion, Mopping performance
Cons: Support and Reliability, Price and Value
Noise was a recurring concern, especially vacuum motors, auto-emptying, and water-wash cycles.
Pros: Mopping performance, Dried-On Stain Removal
Cons: Map and Path Efficiency (Robot Vacuums), Price and Value
The motor itself is controlled, but the conical floorhead becomes excessively loud on hard floors because of its internal combs and small wheels.
Pros: Overall opinion, Price and Value
Cons: Comparative performance, Emptying and Mess Control
