Shark® Rocket® Pro Cordless Stick Vacuum with Self-Cleaning Brushroll
IZ140, IZ140C, IZ141C, IZ142, UZ145
Top and bottom LED lights are flashing (Fig. B): Battery temperature is not optimal, so charging is temporarily paused. Leave battery plugged in and charging will resume soon.
If top 2 or bottom 2 LED lights are flashing (Fig. C, Fig. D), call Customer Service at 1-877-781-7375.
The battery should take approximately 3.5 hours to reach a full charge.
These runtimes are based on 100% capacity:
- Handheld vacuum only mode: approximately 40 minutes
- Handheld vacuum only with BOOST mode: approx. 10 minutes
- Bare Floor mode: approx. 25 minutes
- Bare Floor mode with BOOST: approx. 10 minutes
- Carpet mode: approx. 20 minutes
- Carpet mode with BOOST: approx. 10 minutes
Like all lithium-ion products, the battery will naturally decrease in capacity over time.
Note that battery runtime is affected by the duration of use and the type of surface being cleaned. For example, vacuuming a thick carpet in Boost mode will reduce runtime faster than vacuuming bare floors.
If the battery is too warm after use, the charger will pause until the battery cools before it begins charging.
