Suction power: who pulls harder?
The Shark AI Ultra leads with ≈2,200 Pa, about 20 % more suction than the Roomba 115X Combo models (≈1,800 Pa). If you have thick carpets or pets that shed heavily, that extra pull can make a noticeable difference.
Looking for the strongest suction? Check the current price for the Shark AI Ultra.
Navigation intelligence: mapping vs. vSLAM
Both Roomba variants rely on iAdapt 3.0 with vSLAM—a proven system that builds a map as it cleans. The Shark AI Ultra upgrades to AI Laser Vision combined with Smart Mapping, which tends to create more accurate floor plans faster and handles complex layouts better.
If you have a multi‑room home with lots of furniture, the Shark’s laser navigation may reduce missed spots.

Mopping ability: wet‑clean or vacuum‑only?
The Roomba 115X Combo models include a vibrating mop pad with an 180 ml water tank, delivering light‑to‑moderate mopping on hard floors. The Shark AI Ultra is vacuum‑only—no mopping function.
For homes with mostly tile, hardwood, or laminate where you want a quick wet‑clean pass, the Roomba Combo is the better choice.

Battery life & recharging
Runtime: Shark AI Ultra leads at 120 minutes, giving it an edge for larger homes. Both Roomba models max out at 90 minutes, which is still sufficient for apartments or smaller houses.
Recharge time: Shark refills in 2.5 hours versus 3 hours for the Roombas—a modest advantage if you need quick turn‑around between cleaning sessions.
Value & ongoing costs
The Roomba 115X Combo with AutoEmpty Dock is currently $199.99 (down from $469.99) and includes a self‑empty base that holds debris for up to 60 days, reducing maintenance. The dock‑free version is $139.99. The Shark AI Ultra sits at $249.99 (down from $599.00) and uses a bagless bin you empty manually.
If you dislike frequent bin emptying, the Roomba’s AutoEmpty dock adds real convenience. If you prefer a lower upfront price and don’t mind emptying the bin yourself, the dock‑free Roomba or the Shark may suit you better.
