Prime Day is the perfect excuse for a big, 'treat yourself' purchase like a robot vacuum. And if you've been eyeing one up for a while, then you'll love this amazing deal on the Shark Matrix Plus, now at its lowest-ever price.

As of July 11, this robot vacuum is over 50% off, now priced at $299.99. That's a savings of $400. Who can argue with that?

And this vacuum doesn't just pick up dirt; it mops your floors, too. It uses Sonic Mopping to scrub hard floors 100 times per minute, and if you know it's about to encounter an extra deep stain, head to the app and initiate Matrix Mop to get 50% better stain cleaning in certain spots.

This vacuum is seriously smart, too. It boasts an impressive precision matrix grid, meaning it takes several movements over dirt and debris to ensure it is all removed. And the smart features don't end there: the CleanEdge Detect system uses blasts of air and corner recognition to remove debris from edges and corners, pulling the debris into the cleaning path. Say goodbye to dusty, forgotten corners.

And like all high-end robot vacuums, there's no need to manually map out the path for the Matrix Plus because it uses 360-degree LiDAR vision to learn your space, detect obstacles, and pick up dirt. It also self-empties, self-charges, and holds up to 60 days' worth of dirt, limiting your work even further. The base is bagless, too, so it is both useful and environmentally friendly as it eliminates the need for waste bags.

Grab this deal before it runs out.
