#1
Noise feedback was mixed: some found it not very loud or quieter than upright vacuums, while another measured loud boost-mode operation.
Pros: Filtration / Dust Containment, Build quality and durability
Cons: Clogging and debris prevention, Bin and Bag
#2
Operating noise was acceptable to several reviewers and quieter than some traditional vacuums, but self-cleaning and drying noise remained more bothersome.
Pros: Crevice / Groove Pickup (Hard Floors), Hair‑Wrap / Tangle Resistance
Cons: Hair Pickup — Carpets, Bin and Bag
#3
Noise feedback is mixed, from quiet low mode to complaints about loud high-mode operation.
Pros: Cordless convenience, Edge and Baseboard Cleaning (Hard Floors)
Cons: Carpet — High-Pile Pickup, Scratch resistance
#4
Noise evidence is limited to one test, where Eco and CleanSense IQ sounded reasonable but Boost reached a loud-car or singing range.
Pros: Filtration / Dust Containment, Build quality and durability
Cons: Support and Reliability, Suitability for heavy-duty use
#5
Noise was only directly judged once, with the reviewer comparing the measured level to a gas lawn mower.
Pros: Tool-change simplicity, Assembly and Setup
Cons: Crevice / Groove Pickup (Hard Floors), Carpet — High-Pile Pickup
#6
Noise is only opinionated in one review, where the vacuum was judged nearly as loud as an upright.
Pros: Carpet — High-Pile Pickup, Hair Pickup — Carpets
Cons: Cord management, Bin and Bag
#7
Noise was a repeated drawback: reviewers described the CrossWave as louder than expected, louder than rivals, or quite loud at measured levels.
Pros: Cord length, Cordless convenience
Cons: Under-Furniture Pickup, Crevice / Groove Pickup (Hard Floors)
