Navigation, mapping, and AI obstacle avoidance
The Roomba 115X series uses iAdapt 3.0 with vSLAM (visual simultaneous localization and mapping) and Imprint Smart Mapping. It learns floor plans, labels rooms, and lets you set virtual barriers via the iRobot Home app.
The Shark AI Ultra relies on Shark’s IQ Navigation™, which combines a laser sensor with AI‑powered object recognition to detect and avoid obstacles such as pet waste, cords, and shoes.
Both support multi‑floor mapping and scheduling, but Shark’s laser‑based approach tends to perform better in low‑light conditions, while Roomba’s vSLAM excels at distinguishing carpet from hard floors for automatic suction boost.
Suction power, mopping quality, and dock convenience
Suction: Marketing copy indicates the Roomba 115X Combo delivers up to 2,000 Pa of suction—enough for everyday dust and pet hair. The Shark AI Ultra advertises a higher max suction of roughly 2,700 Pa, aimed at deeper carpet cleaning.
Mopping: Only the Roomba 115X Combo models include a vibrating mop pad with a 300 ml water tank and adjustable water flow. The Shark AI Ultra is vacuum‑only and does not mop.
Dock convenience: The Roomba 115X Combo with AutoEmpty Dock holds up to 60 days of debris in its sealed bag, reducing empty‑bin frequency to roughly once a month for an average household. The Shark AI Ultra uses a standard base station that requires manual emptying after each cleaning cycle.
Which should you choose?
- Best all‑rounder (vacuum + mop + auto‑empty): iRobot Roomba 115X Combo with AutoEmpty Dock – great for homes with mixed flooring and pets who want hands‑free emptying.
- Budget‑friendly mopping option: iRobot Roomba 115X Combo (no dock) – same cleaning performance at a lower price if you don’t mind emptying the bin yourself.
- Strongest suction, laser navigation: Shark AI Ultra – ideal for carpet‑heavy spaces and low‑light rooms where laser‑based obstacle avoidance shines.
