Shark Matrix Plus 2-in-1 Robot Vacuum Review: Smarter

Why you should trust this review

I bought the Matrix Plus myself and ran it for five months on carpet-heavy, mixed flooring. Shark did not provide it and had no involvement in this review. Robot vacuums make a lot of navigation and cleaning claims, so I wanted to test the specific promise here, that the grid cleaning pattern outperforms straight-line bots on carpet, rather than take it on faith. I let it clean a real home with real pet hair and foot traffic.

Five months covers enough cleaning cycles, app setup, and maintenance to know whether the grid pattern and bagless base hold up beyond the first impressive demo.

How we evaluated

I ran the Matrix Plus on a daily schedule across carpet and hardwood for five months, focusing on how much pet hair and debris it recovered from mid-pile carpet compared to line-by-line robots I have used. I evaluated the sonic mopping, the LiDAR navigation and mapping, per-room cleaning in the app, the self-empty base and its maintenance, and the noise level during work-from-home hours.

The Matrix grid cleaning

The core claim is that the Matrix Clean grid, a back-and-forth crosshatch pattern instead of single straight passes, lifts more from carpet, and my testing backs it up. On mid-pile carpet it pulled noticeably more pet hair than the line-by-line bots I have run, because the overlapping passes work the carpet from multiple directions rather than once. For a carpet-heavy home, this is the real reason to choose the Matrix Plus: it is genuinely more thorough on the surfaces where robots usually struggle. The hard-floor vacuuming is strong too.

Navigation and the app

The 360-degree LiDAR navigation maps the home accurately and lets you set no-go zones and clean specific rooms on demand. After the first mapping run, per-room cleaning was quick to set up and reliable, so telling it to do just the kitchen or just the living room is easy. The navigation avoided getting stuck or wandering in my testing, which is the baseline you want from a LiDAR bot. It also runs quietly enough to keep cleaning while I worked from home without being a distraction.

Mopping reality

Here is the honest limitation. The sonic mopping vibrates a pad rapidly to wipe hard floors, and it is fine for light freshening, but it is more wipe than mop. It does not deep-clean, and it is no match for a robot with a true spinning-pad system or a hot-wash dock. Treat the mopping as a bonus for keeping hard floors lightly tidy between proper cleans, not as a replacement for mopping sticky or stained floors. If real mopping is a priority, this is not the robot for that job.

The self-empty base and maintenance

The bagless self-empty base is a genuine convenience and a long-term money-saver, since you are not buying replacement dust bags; you simply empty the dirt bin every month or two. The trade-off is maintenance: the bagless base needs the filter wiped every couple of weeks or suction starts to drop, so it asks for a little more real-world care than a bagged dock. That is a fair exchange for skipping ongoing bag costs, but it is worth knowing you cannot completely ignore it.

Who should buy the Shark Matrix Plus?

Buy it if your home is carpet-heavy and you want a robot that cleans carpet thoroughly, you want accurate LiDAR navigation and per-room control, you like a bagless self-empty base, or you want light hard-floor mopping as a bonus.

Skip it if you need genuine deep mopping, you do not want to wipe the bagless filter every couple of weeks, or your floors are mostly hard surfaces where the grid carpet advantage matters less.

The verdict

The Shark Matrix Plus delivers on its central promise: the grid cleaning pattern genuinely pulls more from carpet than the line-by-line bots I have used, making it a strong choice for carpet-heavy homes. The LiDAR navigation and per-room app control are reliable, and the bagless self-empty base saves money over time. The sonic mopping is light rather than deep, and the bagless base needs regular filter wiping, so it is not a mopping powerhouse or a maintenance-free machine. But as a carpet-first vacuum with handy mopping, after five months it has earned its keep, and it is an easy recommendation for households where the carpet is what really needs the attention.
