Shark Stratos Cordless Vacuum vs Dyson V15 Detect

The Dyson V15 Detect is the stronger vacuum overall: it weighs about 7 lb against the Shark's 12.4 lb, has a detangling motorbar, a laser that shows dust on hard floors, and a screen that reports what it picks up. The Shark Stratos counters with an odor neutralizer, a self-cleaning brushroll, and a folding wand for compact storage, and owners say it pulls pet hair well. Buy the Dyson if you want lighter weight and smarter cleaning feedback; buy the Shark if pet odor and storage space matter more to you.

• Choose the Shark Stratos if you want odor control, a self-cleaning brushroll and a wand that folds for tight storage.
• Choose the Dyson V15 Detect if you want a lighter vacuum with a laser dust light, a detangling brush bar and on-screen cleaning data.
