Why is My Shark Vacuum Spitting Stuff Back Out? Common Causes and Solutions
A Shark vacuum may spit stuff back out if it is clogged with debris or has a dirty filter. When the vacuum is on, air flows through the filter and into the canister or bag, but if the filter is clogged, the air has nowhere to go and may end up pushing dirt and debris back out of the vacuum. Similarly, a clogged hose or brush roll can cause the vacuum to clog and spit dirt and dust back out.
