Which One Should You Choose?
If you want a vacuum that also mops and empties itself for under $200, the Roomba 115X Combo with AutoEmpty Dock is the standout choice. It gives you hands‑free mopping and a self‑emptying bin, ideal for busy homes or pet owners.
If you prefer maximum suction and longer runtime, and you don’t need mopping, the Shark AI Ultra delivers stronger airflow and a larger battery, making it great for carpets and larger floor areas.
For a budget‑friendly option that still mops, the Roomba 115X Combo without the dock offers the same cleaning performance at $139.99; you’ll just need to empty the bin manually after each run.
