Here is an honest breakdown.

Cordless Shark Vacuums

Runtime Reality Check
Advertised runtimes are often misleading. Here is the reality:
| Mode | Advertised | Real-World |
|---|---|---|
| Eco (Hard Floor) | 60 min | 45-55 min |
| Normal (Mixed) | 40 min | 30-40 min |
| Boost (Carpet) | 20 min | 12-18 min |
If your home takes more than 30 minutes to vacuum on carpet, cordless may not be enough.
Our Recommendation
- Choose Corded if: You have a large home, prioritize deep cleaning, or want the lowest long-term cost.
- Choose Cordless if: You have a smaller home, hate dealing with cords, or primarily clean hard floors.
The Hybrid Strategy: Many large-home owners buy a corded upright (Rotator or Navigator) for weekly deep cleans and a cordless stick (Rocket or Wandvac) for daily quick pickups. This gives you the best of both worlds.

TIP: If you choose cordless for a large home, buy a second battery and an external charger. You can swap batteries mid-clean and double your effective runtime.
