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.

V12 Detect Slim: 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.
