If the battery is nicad they will not tolerate leaving on charger past full charge.

Either the battery pack needs replaced or the charger is not working correctly.

That is probably the belt. Open up the bottom screws and take a look. The cat or dog hair usually gets stuck in the ends of the rollers and stops the belt from effectively pushing the roller. You may find that the belt is still on the drive and the roller. If you do just clean out the roller.

If it will not come on there are several things you need to check. First off you should call and have your model type and serial number checked to be sure your unit isnt affected by the recall they had due to expanding batteries. Second you do have a 2 year warranty on the unit and if it wont even turn on there may be a defect. Are the blue charging lights coming on? If they are and your transformer is warm then there is more then likely a defective battery in the unit and you should contact customer service at 1800-896-9756

If the unit itself is under a year I would take it back to the store. It sounds like the unit is not charging properly which you already know. Check to see if you actually have charge coming out of your charger. Usually there is a charge light. Is it bright when charging? If you have a volt meter you can check the voltage coming out of the charger to verify if there is indeed voltage coming out. Let me know what you discover.

I am not certain about this specific battery, however, if many batteries are unused for a long period of time, they can not be rejuvenated.
Try the switch in each position for 24 hours and if there is no action, it is probably not worth repairing.
