My CrossWave is making a loud noise - BISSELL International

When reclined, the brush will spin - this sound is normal
When dirty tank is full, the float inside will activate and the motor pitch will change
- This sound is normal and the dirty water tank should be emptied
- While emptying the dirty water tank, rinse and manually move the float up and down to ensure it moves freely
- Also be sure to insert the filter completely in place (reinstall it)

CrossWave rinse the filter

With the machine turned off and unplugged, check to see if the front nozzle and brush roll are installed properly on the foot
- Spin brush roll by hand to verify smooth motion
If the noise extremely loud or abnormal, please contact BISSELL Consumer Care
The CrossWave can operate up to 80 decibels with both the brush and vacuum motor on
