Robot vacuum with sonic mopping, Matrix Clean grid navigation and a bagless HEPA self-empty base holding up to 60 days.
Verdict: Bagless self-emptying is a real cost saver, but navigation and reviews are middling.
The Shark Matrix Plus 2-in-1 (RV2610WA) vacuums and sonic-mops hard floors at once, cleans in a precision Matrix grid, uses CleanEdge air blasts for corners, and empties into a bagless HEPA base with no bags to buy.
