Need 2 batteries for my 2500 SF house. After 10 mos orginal battery not lasting as long. Purchased second one later. My issue: it cannot get under 30" deep desk without the roller raising off the floor. Manufactured to tilt just so far. The canister thickness also does not allow much to go under a couch, chair or my 13" deep console. So need to use a dust mop to finish the job. Suction pulls up my 1/4" area rug, but it not meant for carpet any thicker. Just too lightweight and the roller does not engage into the nap. No pets or children. Overall, satisfied with the product. The Hoover ONEPWR system has only been around since 2019. I've owned for 10 month. Cannot say how long this product will last.
