Pros and cons of Shark IONflex
- 2 battery packs. You can run up to 60 minutes and do not need to wait for the charging time.

- You can use as a stick vacuum a handheld vacuum for cleaning from top to bottom. The under-appliance wand is useful for reaching under table, bed, sofa.
- A lot of attachments: Duster crevice tool, Anti-allergen dusting brush, Pet multi-tool, MultiFLEX under appliance wand.

- A bit heavy. The whole unit is 8.7 lbs, which is much higher than Dyson (5.85 lb typically). When using as a floor vacuum cleaner, it does not have any issues. However, when transforming into a hand-vac, Shark IONflex is top-heavy and can cause fatigue.
- No HEPA filters. If you have asthma, we highly recommend you to pick Dyson V8 to ensure the air quality.
