Post-Purchase Truths

V15 Detect Absolute: What to watch for

Ergonomics
Continuous trigger hold causes index finger and grip fatigue.
You must hold down the power trigger continuously during the entire vacuum session. There is no on/off toggle lock on standard models.
Maintenance
Emptying fine plaster or drywall dust can jam the silicone squeegee.
Very fine powder can stick to the inner cyclonic shroud, requiring periodic disassembly and manual wiping.

V8 Absolute: 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.
