Feature Showdown
Cleaning capability
Both Roomba 115X models are marketed as “Combo” units, meaning they vacuum and mop in a single pass. The Shark AI Ultra focuses solely on vacuuming, relying on a powerful suction system and a self‑cleaning brushroll to pick up debris.
Navigation and mapping
The Roomba line uses iRobot’s iAdapt navigation with obstacle detection, while the Shark AI Ultra advertises AI‑driven laser mapping that learns your home’s layout and avoids obstacles in real time.
Smart home integration
All three models support Wi‑Fi connectivity and can be controlled via their respective smartphone apps (iRobot Home for Roomba, SharkClean for Shark). They also work with voice assistants — Roomba with Alexa and Google Assistant, Shark with Alexa and Google Assistant.
Auto‑empty dock
Only the Roomba 115X Combo with AutoEmpty Dock includes a self‑emptying base that holds up to 30 days of debris, letting you forget about daily bin emptying. The other two models require manual emptying after each cleaning cycle.

- Best for hands‑free convenience: Roomba 115X Combo with AutoEmpty Dock – ideal if you hate emptying the bin and want mopping built‑in.
- Best budget combo: Roomba 115X Combo – solid vacuum‑and‑mop performance at a lower price, perfect for small‑to‑medium homes.
