Performance on Different Floor Types
Owners who’ve switched from carpets to hardwood or tile notice that brush‑roll design matters. On dense wool carpeting, both the Roomba 115X series and the Shark AI Ultra capture about 15 % more dust than the older 110X line.
On hardwood and tile, the Roomba’s dual‑action mopping sheet leaves a streak‑free shine, while the Shark’s AI mopping maps high‑traffic spots and guarantees roughly a 90 % reduction in smudges.
Which One Should You Buy?
If you value hands‑free emptying and a polished mop finish on hard floors, the Roomba 115X Combo with AutoEmpty Dock is the best fit.
If you prefer stronger suction for carpets and a longer runtime, the Shark AI Ultra delivers the extra power you need.
Both models work with Alexa and Google Assistant, so pick the one that matches your cleaning habits and budget.
