Noise drew strong praise in the hands-on review that described the PencilWash as very quiet and usable without disturbing others.
Pros: Noise level, Under-Furniture Pickup
Cons: Tool-change simplicity, Crevice / Groove Pickup (Hard Floors)
Noise drew strong praise in the hands-on review that described the PencilWash as very quiet and usable without disturbing others.
Pros: Noise level, Under-Furniture Pickup
Cons: Tool-change simplicity, Crevice / Groove Pickup (Hard Floors)
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: Tool-change simplicity, Storage footprint and upright-stand stability
Cons: Steam Cleaning, Scratch resistance
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: Packaging quality, Versatility
Cons: Overall durability/longevity, Scratch 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: Pet-Ready Features, Accessories and Tools
Cons: Automatic shutoff for obstructions, Crevice / Groove Pickup (Hard Floors)
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: Pet-Ready Features, Tool-change simplicity
Cons: Fresh Liquid Pickup Speed, Clogging and debris prevention
Reviewers generally found standard cleaning quiet or manageable, with louder moments on high suction or during dock activity.
Pros: Hair-removal channel issues, Hair‑Wrap / Tangle Resistance
Cons: Accessories and Tools, Stair Cleaning
Noise impressions were mostly favorable for the power level, especially dock noise, though one review still called the robot noisy in some configurations.
Pros: Hair Pickup — Carpets, Large debris handling
Cons: Stuck resistance, Dirty water sensor
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: Fresh Liquid Pickup Speed, Ongoing ownership costs (bags
Cons: Filtration / Dust Containment, Under-Furniture Pickup
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: Versatility, Floor shine after cleaning
Cons: Odor control, Stuck 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: Stuck resistance, Assembly and Setup
Cons: Clogging and debris prevention, Suitability for small spaces
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: Tool-change simplicity, Assembly and Setup
Cons: Suitability for heavy-duty use, Ongoing ownership costs (bags
Noise was acceptable for scheduled cleaning in some homes, but reviewers noted louder maximum suction and dock/drying sounds.
Pros: Maneuverability and Handling, Versatility
Cons: Under-Furniture Pickup, Low-profile design
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: Pet-Ready Features, Filtration / Dust Containment
Cons: Ongoing ownership costs (bags, filters
Noise was a recurring concern, especially vacuum motors, auto-emptying, and water-wash cycles.
Pros: Tool-change simplicity, Versatility
Cons: Value-for-money, Support and Reliability
The motor itself is controlled, but the conical floorhead becomes excessively loud on hard floors because of its internal combs and small wheels.
Pros: Pet-Ready Features, Tool-change simplicity
Cons: Noise level, Product availability
