very upset about Dolphin Pro

by Abbey

I purchased a dolphin pro at the begining of summer. I have used it a few times with no problems. Ive followed all instructions on how to operate, and care for it. The last few times ive tried to use it it starts up as it should rolls a few times and stops. ive taken it completely apart to see if maybe there was some debris, still not working! I spent a lot of money on this, and im highly upset im unable to use it! Any tips or helpful advice you could give me would be greatly appreciated.
ADMIN REPLY: You must determine if the problem is the robot or the power supply. If you bought new then return it or take it to a repair shop.
thanks,not a fan of dolphins momentarily
