Shark AI Ultra vs. iRobot Roomba 105 Combo: Which Robot Vacuum?
Vacuum-only vs. vacuum+mop: a capability matrix and honest pick between the Shark AV2511AE and Roomba 105 Combo, with verified prices.
The decision problem
"Is a robot vacuum worth it?" depends on your floors and whether you want mopping. Both self-empty and map with LiDAR; the real fork is mopping (Roomba) vs. lower ongoing cost (Shark is bagless).

Who should buy which
- Shark AV2511AE — you want vacuuming, prefer a bagless base (no recurring bag cost), and don't need mopping.
- Roomba 105 Combo — you want vacuum + mop in one and don't mind buying AutoEmpty bags and mop pads over time; it's also the lower price right now.
- Neither — thick high-pile carpet throughout, or you expect it to replace a full-size vacuum.
Ongoing costs
The Shark is bagless (nothing to rebuy for the base). The Roomba uses AutoEmpty bags plus mop pads — recurring costs beyond the sticker price.
Limitations & alternatives
Both struggle with clutter and edges, and neither deep-cleans thick carpet like an upright.
