My husband and I are in our 80s with the usual arthritis and back problems. When we bought this vacuum we thought we had gone to Heaven early. It is so light and flexible and it gets under and around furniture so easily. The suction is terrific and emptying the canister is a snap. So we bought a second one for the other side of the house. The minute it arrived the first one would only run for less than a minute and then shut off. It was fully charged but still refused to work! I feel really let down by a product bearing the Eureka name. Eureka has been the name of choice for over 50 years in our household. Such a shame!
