Most robot vacuums make one pass over your carpet and move on. The Shark Matrix Plus drives a tight grid, going back and forth over the same patch to lift dirt that a single sweep leaves behind. For the carpeted homes that are so common in Britain, that one design choice is what makes it our best pick — here is how it works and where it falls short.
Carpet is where cheap robot vacuums quietly fail. They glide across the surface, pick up the loose fluff on top, and leave the grit pressed down in the pile. The Shark Matrix Plus is built to fix exactly that, using a grid-pattern clean and a self-emptying base, with sonic mopping for the hard floors in between. Shark is also a brand most British buyers already know and trust, with proper after-sales support behind it. It is not the most polished robot here on software, and the bin and dock are on the bulky side, but on carpet it pulls out more than its rivals — which is precisely why it earns its place.

The verdict from Raj Patel, home appliance tester
The best pick for carpeted homes. Where most robots make a single pass and move on, the Shark Matrix Plus drives a tight grid pattern over an area, going back and forth to lift embedded dirt — which is exactly what carpet and rugs need. Add a self-emptying base and sonic mopping that vibrates rather than just dragging, and you get a robot built for British homes with plenty of soft flooring. It is not the cheapest mid-ranger and the app is a step behind the specialists, but on carpet it pulls out more than its rivals.
You can hear it making that extra back-and-forth pass over a rug, and the pickup in the bin afterwards proves it was not for show.
The Matrix Plus is the right robot if your home is mostly carpet and rugs and you have been let down by robots that seem to skim the surface without really cleaning it. It suits living rooms with fitted carpet, bedrooms with rugs, and the kind of mixed British home that has soft flooring upstairs and a tiled kitchen and hallway downstairs. It is also a sensible choice if you value buying from an established UK brand with accessible spares and support, rather than gambling on an unfamiliar name.
It is less of an obvious buy if your floors are almost entirely hard. There the grid-cleaning advantage matters far less, and a vacuum-first robot like the Roborock Q5 Pro gives you stronger headline suction and slicker mapping for less money. It also is not the machine to buy if you want the very hands-off, self-washing-mop experience of the premium tier — for that you would look at the Roborock S8 Pro Ultra or the more affordable Dreame L10s Ultra. The Matrix Plus is a carpet specialist first, and it should be judged on that.
The headline feature is the one that justifies the price, so it is worth understanding properly. A normal robot cleans in long parallel rows, passing over each strip of floor once. The Matrix Plus instead breaks an area into a grid and cleans each section with repeated, multi-angle passes — driving over the same patch several times from different directions before it moves on. On hard floors that would be overkill, but on carpet it is exactly what is needed, because embedded grit only loosens when the brush works it from more than one angle.
In testing, the proof was simply in the bin. Run the Matrix Plus over a rug that a single-pass robot had already "cleaned", and it still pulled out a visible amount of fine grit and pet hair the first pass had pressed down and left behind. That is the whole argument for this machine. The trade-off is time: making several passes over a grid is slower than one sweep, so a full clean takes longer, and the battery — around 120 minutes — is shorter than the marathon runtimes of some rivals. For most homes it still finishes the floors it is set on in a session, but a very large house may want it to clean room by room rather than all at once.
This is a 2-in-1, so it mops as well as vacuums, and the mopping is better than the usual token effort. Instead of a flat cloth dragged passively behind the robot, it uses sonic mopping — the pad vibrates at speed, scrubbing the floor rather than just smearing water over it. On a tiled kitchen or a laminate hallway that means it shifts light, dried-on marks that a plain drag pad would slide straight over. It is not a deep scrub on the level of the spinning twin pads on the premium machines, but for day-to-day maintenance of hard floors it does a genuinely useful job.
Navigation is handled by LiDAR mapping, so the robot builds an accurate map of your home and cleans methodically rather than at random, and you can direct it to specific rooms from the app. Combined with the grid pattern, that means it covers a carpeted room thoroughly and predictably. If your home is a mix of carpet upstairs and hard floors down, the Matrix Plus copes with both — though it earns its money on the soft flooring, and the mopping is best thought of as a capable bonus rather than the reason to buy.
The Matrix Plus comes with a self-emptying base, which is the feature that turns a robot from a daily chore into a near-set-and-forget appliance. After each clean it returns to the dock and empties its onboard bin into a larger bag in the base, so you are not popping the lid and tipping out dust every other day. The base holds weeks of debris before it needs attention, which matters most in exactly the homes this robot is aimed at — carpeted, pet-owning households generate a lot of hair, and a self-empty base means you deal with it monthly rather than constantly.
The honest maintenance note is that you will still rinse the mop pad yourself and refill the small water tank when you use the mopping, as there is no self-washing dock here as on the premium machines. You will also occasionally clear hair from the brush roll, as with any robot in a hairy home. None of this is onerous — it is simply worth being clear that this is a self-empty base, not the full self-cleaning station you get when you spend twice as much. For the price, the balance is fair. If full hands-off mopping is your priority, that is the case for stepping up to a self-cleaning dock, and our guide on whether you need a self-emptying dock walks through where the line falls.
Two things hold the Matrix Plus back from being a flawless recommendation. The first is bulk: the self-empty base and the bin are on the larger side, so the dock takes up more floor and wall space than some rivals, and you need a clear stretch of skirting for it to live against. In a small flat that is worth planning around before you buy. The second is the app. Shark's software does the essentials — mapping, room selection, scheduling — but it feels a step behind the polish and depth of the Roborock and iRobot apps, with fewer fine controls and the odd rough edge. None of this stops it cleaning well; it just means the experience around the cleaning is less refined.
Set against the carpet performance, neither drawback is a deal-breaker for the home this robot is built for. If you mostly have hard floors, the app and bulk count for more and you should look elsewhere; if you have carpet and want it genuinely clean, they are easy compromises to accept. It comes down to your flooring, which is the right way to choose any robot — see our buying guide and our piece on robot vacuum versus a traditional vacuum if you are still weighing it all up.
Instead of making a single straight pass and moving on, the Matrix Plus drives a tight back-and-forth grid over an area, cleaning each patch from multiple directions. That repeated, multi-angle passing is exactly what lifts dirt out of carpet and rugs, which is why this is our pick for homes with a lot of soft flooring.
Yes. It comes with a self-emptying base that the robot returns to after each clean, holding weeks of debris before you need to empty it. Combined with the grid cleaning and sonic mopping, that makes it a genuinely low-maintenance robot for carpeted UK homes.
Yes — its sonic mopping vibrates the pad to scrub rather than simply drag, so it handles tile, laminate and vinyl well. Its real advantage over rivals is on carpet, though. If your home is almost entirely hard floor, a dedicated scrub-mopping flagship like the Roborock S8 Pro Ultra may suit you better.
The Shark Matrix Plus is our best pick for carpet because its grid-cleaning pattern does the one thing carpeted homes most need: it makes repeated, multi-angle passes that lift embedded grit single-pass robots leave behind, and the bin afterwards proves it. Add a self-empty base, capable sonic mopping for the hard floors in between, and a trusted UK brand behind it, and you have a robot built for British homes with plenty of soft flooring. The honest caveats are the bulkier dock and an app that trails the specialists, and the fact that on mostly-hard floors a robot like the Roborock Q5 Pro makes more sense.
