CHECKING FOR BLOCKAGES

Blockages may cause your vacuum to overheat and
shut down. To prevent this from happening, check
potential blockage areas after heavy use or if you
detect a loss of suction or poor cleaning performance.
1 Dust Cup
Dust cup may be full. Empty dust cup.
2 Pre-Motor and Post-Motor Filters
• Pre-motor filters require washing every 3
months for optimum performance.
The post-motor HEPA filter needs to be washed
every 2 years.
• Ensure that all the filters are clean.
3 Accessories
• Check intake openings:
- Extension Wands
- Dusting Brush
- Crevice Tool
