iRobot Roomba 115X Combo Robot Vacuum & Mop with AutoEmpty Dock
SolidWhat’s in the Box?
The iRobot Roomba 115X appears in two configurations: the base Combo robot vacuum‑mop (Roomba 115X Combo) and the same unit paired with an AutoEmpty Dock that empties the bin automatically (Roomba 115X Combo + AutoEmpty Dock). Across the aisle, Shark offers its AI Ultra line – the standard Shark AI Ultra (Shark AI Ultra) and the AV2501S variant that adds a self‑empty base (Shark AV2501S AI Ultra).
Suction, Navigation & Mopping
All four units use laser‑based LiDAR mapping for room‑by‑room navigation and multiple cleaning passes. The Roomba 115X Combo includes a removable mopping pad and a water tank, while the Shark AI Ultra relies on powerful suction alone (no mopping). Both the Roomba models with the AutoEmpty Dock and the Shark AV2501S self‑empty base cut down manual bin emptying after each run. Suction ratings sit in the 2000‑2500 Pa range – enough for pet hair on low‑pile carpet and fine debris on hard floors.
Performance on Floors, Pet Hair & Maintenance
On hardwood and tile, owners report >90 % pickup of fine dust in a single pass for both brands, according to aggregated 2026 reviews. For pet hair, the Roomba’s rubber‑brushed extractor tangles less than Shark’s traditional bristle brush, which some users note requires occasional hair‑wrap cleaning. The AutoEmpty Dock and Shark’s self‑empty base each hold up to 30 days of debris before needing a bag change, dramatically reducing maintenance.

If you want mopping and the lowest entry price, the Roomba 115X Combo delivers strong suction and a wet‑mop pad for under $140. For hands‑free emptying, step up to the Roomba 115X Combo + AutoEmpty Dock – still under $200 and keeps the bin clear for weeks. If you prefer Shark’s deeper carpet suction and don’t need mopping, the Shark AV2501S AI Ultra gives you self‑empty convenience at $240. The plain Shark AI Ultra is the most affordable Shark option if you’re okay manually emptying the bin after each run.
