I purchased this at end Nov and received mid Dec. it was working great with great suction and we use twice to three times a week. Haven't used the mop function yet. It now will not hold a charge at all on either battery and makes this exceleration noise and then just shuts off. All filters clean and free from debris. Disputed on my credit card today as I'm tired of just throwing it away and buying another something especially less than 3 mos out
