In 2026, picking a robot vacuum is no longer just about suction power—it’s about finding a cleaning partner that handles mopping, navigation, and self‑emptying with ease.
If you juggle pet hair, allergies, or a packed schedule, the right model can give you back hours each week. This guide pits the iRobot Roomba 115X Combo (with AutoEmpty Dock) against the Shark AI Ultra lineup so you can match features to your real‑world needs and buy with confidence.

Performance on Different Floor Types
Carpets, Hardwood, Tile & Pet Hair
According to aggregated owner feedback and third‑party lab reports (2024‑2025 data still cited in 2026 retailer listings), the Roomba 115X Combo delivers 1800 Pa suction that lifts fine dust from low‑pile carpet and pulls debris from grout lines on tile. Its vibrating mop pad adds roughly 15 % more stain removal on sealed hardwood compared with dry‑only passes, based on user‑reported before/after photos.
The Shark AI Ultra’s 2700 Pa suction outperforms on medium‑pile carpet, extracting embedded pet hair that lighter‑suction models often miss. However, it lacks a mopping function, so hard‑floor shine relies solely on vacuum passes.
Which Model Fits Your Home?
- Choose the Roomba 115X Combo with AutoEmpty Dock if you want hands‑free emptying, mopping capability, and seamless Apple HomeKit integration.
- Choose the Roomba 115X Combo (no dock) if you prefer a lower upfront cost and don’t mind manually emptying the bin.
- Choose the Shark AI Ultra if maximum suction for deep carpet cleaning is your top priority and you don’t need mopping.
- Choose the Shark AV2501S AI Ultra for a slightly lower price than the AI Ultra while retaining the same strong suction and lidar navigation.
