Post-Purchase Truths

Dyson: What to watch for

Hardware Quirk
Tiny 0.10-gallon dustbin requires emptying 2–3 times per cleaning.
The compact canister fills up rapidly in homes with multiple shedding pets, interrupting cleaning flow.

Shark: What to watch for

Maintenance
Washable filters must air-dry for a full 24 hours before reassembly.
Running the vacuum with a damp filter can damage the suction motor and cause musty odors, requiring an overnight wait or spare filter.
