Cleaning Performance & Navigation Technology
All three models rely on sensor‑based navigation, but the approach differs.
- Roomba 115X series: iRobot’s vSLAM (visual simultaneous localization and mapping) plus a bumper‑based obstacle detector.
- Shark AI Ultra: Laser‑based LiDAR for mapping, complemented by infrared sensors for object avoidance.
Suction Power
- Roomba 115X Combo (both versions): 1,700 Pa in boost mode.
- Shark AI Ultra: 2,200 Pa in Max mode.
Owner feedback (aggregated from verified reviews) shows that on low‑pile carpet the Shark AI Ultra often pulls out more embedded pet hair, while the Roomba 115X excels on hardwood thanks to its dual‑action brush system and consistent mopping performance.
Which Model Should You Choose?
If you want true hands‑free operation – the Roomba 115X Combo with AutoEmpty Dock empties itself for up to a month, making it ideal for busy households or larger homes up to 2,000 sq ft.
If you need strong carpet suction and don’t mind emptying the bin yourself – the Shark AI Ultra’s higher 2,200 Pa suction gives it an edge on pet‑heavy carpets, and it covers up to 1,800 sq ft.
If you’re looking for the best value – the Roomba 115X Combo (no dock) delivers vacuum‑and‑mop capability at $139.99, perfect for apartments or homes under 1,500 sq ft.

All three robots are solid performers in 2026. Match your priority—self‑emptying convenience, carpet suction power, or upfront price—to the model that checks those boxes. Click the affiliate links above to see current prices and make your purchase today.
