Common Questions

Why does my Hoover Quest keep beeping even after fixing error?

Perform full reset: Hold power button 10 seconds, release, wait 30 seconds, power back on. This clears error memory. If beeping continues, underlying issue not fully resolved or sensor damaged.

Can I still use Hoover Quest if it shows error code?

Depends on error. Minor errors (dustbin, brush stuck): vacuum may work but with reduced performance. Critical errors (wheel stuck, charging error): vacuum stops completely until fixed. Always resolve errors for optimal cleaning.

How do I reset Hoover Quest after fixing error?

Most errors clear automatically when issue resolved. If error persists: turn off vacuum, wait 30 seconds, turn back on. For persistent errors: full reset (hold power 10 seconds).

What does flashing blue light mean on Hoover Quest?

Flashing blue = normal operation, cleaning in progress. Solid blue = charging. Red flashing = error (count beeps for error code). Yellow flashing = warning (minor issue, usually resolvable).

Where can I buy replacement parts for Hoover Quest?

Hoover official website, Amazon, Walmart. Common parts: dustbin ($25-35), brushes ($15-20), filters ($8-12), wheels ($12-18). Always verify compatibility with your specific Quest model number.
