After less than 2 1/2 years of using the Kyvol E31 robovac twice weekly on about 1200 sq. ft. of wood floors, the battery died. I called customer service and not only do they not sell replacements, but they state that replacing it may damage the unit. I checked several websites and not one had a listing with the same specs. Now, after slightly more than 2 years, my robovac is dead and heading for the trash. I purchased another brand as a replacement and verified that the manufacturer sold replacement batteries for their units. Once burned, twice cautious!
