Turns off after 10 minutes of normal useage then comes back on 20 minutes later

If after a few more discharge, charge cycles unit still underperforms then return for exchange or money back. Newer batteries have to be "exercised" a tad before they perform up to specs. And if they say 20 minutes, then hold them to it!!!!!!!!!!!!!!

internal short most likely to a feed wire to the motor

I have a Silver Moon S558, when I turn it on the power light comes on and a few secords later the red warning light comes on. What is causing the vacuum not to work? One day I was vacuuming, turned it off and a few minutes later went to turn it on and nothing, but these lights turning on. Is there a fix?

Depending on what gas appliance you are describing, this is normal...or not. Please tell us exactly what appliance, the manufacturer and the model so we can get you fixed up:) Farmerbear

i had a similar thing happen and just got off the phone with dyson. there is a resettable switch on the handle. they told me to start the vacuum in the upright position, put it in the non upright position, then push and hold in the beater bar switch which is located next to the on/off button for 10 seconds and the beater bar should start to function once again

Could be fault @ plug.. try cutting off 10 mm of cable then redo plug ..Replace fuse then try, if still dead try switch, you could short this out or if you have multimeter check for contact...if stii no action could be motor....

carpet brush won't turn when vac on

You could have a clog in the hose. Also check your filters, if you haven't changed them in a while, that could be what's suffocating your motor

If you have a 400 series Roomba, try removing the battery, then holding down the power button for ten seconds, then recharging the unit before you run it again.

If you have a 500 series Roomba, don't take out the battery-- just press and hold the "spot" and "dock" buttons for about fifteen seconds. The Roomba will play a tune, and you can then charge it and try running it again later.
