How to Check and Clear Hose Blockages
Low suction or poor pickup may be due to a blockage in the vacuum cleaner.
1. Remove hose and check suction at end of hose - if little or
no suction, check disposable dust bag. Change if needed.
If no improvement proceed to step 2.
NOTE: Turn off the switch and unplug the electrical cord
before clearing hose.
2. Disconnect the hose adapter from the unit. Press adapter
button on hose adapter and lift up.
Check for any obstructions that may be in the hose. Any
obstructions can be removed by using a blunt instrument to
clear the hose. Flexing the hose may help loosen the clog.
3. Reinstall the hose after clearing the clog. Insert the hose
adapter button into the bag compartment tube hole. Lift up
on the hose adapter to be sure it is secured.
NOTE: If no improvement in performance on carpet, proceed
to following page.
