The Dyson V15 is lighter, quicker to maintain, and has the more durable battery. The Shark Stratos costs about $400 less and cleans nearly as well on most floors. The gap is worth paying only if you have deep carpet or shedding pets.

| Spec | Dyson V15 | Shark Stratos |
|---|---|---|
| Price | ~$949 | ~$549 |
| Filter upkeep | Rinse, dry 4 hrs, $39/yr | Foam tears in 8–10 washes |
| Battery | $99 swap, more durable | $79 swap |
| Weight & handling | Lighter, easier | Heavier |
| Value | Premium price | Far cheaper for similar pickup |
The V15 Detect sits around $949, the Stratos around $549. That $400 gap is the whole decision: nothing about cleaning performance is far enough apart to outweigh the price on most floors.
On bare floors and short carpet, owners rarely report a difference. On deep pile and fine dust, the V15's higher peak suction and laser head show up. With pets and rugs, that gap is real enough to feel.
