We have 2 Nano's. One is on it's 4th year and the second one at home is just over 3 years old. Still performing well. I do make it a point to keep the two filters clean and the canister cleaned out thoroughly every few months. I think the average user just vacuums and dumps the dirt. At just over $50 for 4 years and counting. Priceless...
