My Big Green Deep Cleaning Machine® brushes are not turning. What should I check?


1. The brush only turns when the handle is reclined.  Make sure you lower the handle before cleaning.

2. The brush’s internal circuit breaker may have tripped. To fix this, turn the machine off (O) and unplug it.  Turn the cleaner on its non-corded side. Check to see if anything is caught in the brush roll.  Also, pull the black tab (in between the brush roll and the two gray rollers) and swing the brush and the brush holder out (pictured below). Clear out any debris in this area. If something is stuck, remove it, plug the machine in to reset the circuit breaker, and retry.

3. Open the brush carriage to check the belt and make sure it’s intact (see pictures below).  Reseat the belt if it has fallen off. For detailed instructions, see the user guide by clicking here:

If the belt is broken, you’ll need to replace it. You can order a new one here:

4. If the brush is damaged and needs to be replaced, you can replace it by clicking here:

To remove and reinstall the brush, unplug the cleaner and turn the unit on the corded side to remove the brush endcap.  Press the brush carriage clip.  Unscrew the three endcap screws.  Remove the old brush and reinstall the new brush, put the endcap on, and replace the screws.
