Shark Matrix Plus 2-in-1 robot vacuum review

Shark Matrix Plus 2-in-1 two-minute review

I’ve been testing robot vacuums for several years and, while I’ve long accepted that no robot will ever allow me to retire from manual vacuuming altogether, I’m forever hopeful one will come close! Shark has an excellent reputation in the vacuuming world, so I was cautiously optimistic when the Shark Matrix Plus Robot 2-in-1 landed on my doorstep.

Some might say the popular tech brand was late to the robot party, at least in the UK. Shark has had success with robot vacuums in the US for a while now, but only added them to its UK lineup in spring 2024. I tested the Shark Matrix Plus 2-in-1 Self-Empty, which can vacuum, mop and empty its own bin. Happy days.

As you might expect from Shark, this smart little robot packs plenty of techy features. A major highlight is its 360-degree LiDAR sensors. This light detecting and ranging technology is aimed at quickly and accurately mapping your home and navigating around obstacles and I can confirm the Shark’s works very well. It also has a special air blasting feature, which I haven’t encountered before, that blows out air to push debris away from edges and corners and into the path of the suction channel. Again, I was impressed.

Although it didn’t blow my mind, the mopping results were better than I’ve experienced from a robot in the past. Rather than just dragging a vaguely damp mop pad along the floor, the Shark Matrix Plus Plus’ mop pad oscillates as it goes (100 times a minute, allegedly), to mimic a scrubbing motion. Many people will also love that the bin unit the self-emptying vacuum discharges into doesn’t need to be emptied for 60 days. Unless you have two hairy kids and two hairy dogs that is – I didn't make it past two weeks.

I tested the Shark Matrix Plus 2-in-1 on the ground floor of my four-bed home for a month. Although it wasn’t perfect and the app wasn’t as slick as I’m used to, I really did rate this robot, especially for those who are tight on money as well as time. I'd have no qualms about giving it a place on our best robot vacuum list . Read on for the full low down on my time testing the Shark Matrix Plus 2-in-1 robot vacuum.

Shark Matrix Plus 2-in-1 specs

Shark Matrix Plus 2-in-1 review: price & availability

• List price: $699.99 / £449.99
• Available: US and UK

The Shark Matrix Plus 2-in-1 sells in the US for $699.99 on Shark’s own website. At time of writing, there are seven robots in the range, with the Matrix Plus being the third most expensive, behind two PowerDetect models that come with self-refill water reservoirs in the base and cost up to $999.99. The cheapest Shark robot you can get in the US is the Shark ION , which is just $279.99 but unappealingly basic.

There are just three robot models available in the UK, and the Matrix Plus 2-in-1 I tested boasts the most diverse spec. In the world of robot vacuuming, I’d say its £449.99 price tag is more than reasonable (even allowing for exchange rates, it’s a better deal than in the US), but you can save yourself £100 if you empty the bin manually and get the entry-level model that still mops but doesn’t self-empty. Or, if you mostly have carpets so want a robot that’s more focused on vacuuming, invest £50 more and go for the top spec Shark PowerDetect .

Whichever side of the pond you are shopping for a Shark Matrix Plus, I’d say the brand has priced it very reasonably, especially when you consider most robots that include mopping capabilities, for example iRobot ’s Roomba, cost $1k plus. It’s not entirely flawless, but the Matrix Plus 2-in-1 represents excellent value in terms of build quality, features and cleaning prowess.

Shark Matrix Plus 2-in-1 review: design

• Low-key looks
• Compact base station
• Tricky mop insert

The Shark Matrix Plus 2-in-1 won’t blow your mind with its futuristic looks or striking shape, but it won’t scare the horses either. It’s black and round with a neat little base and sat under the table in our hallway just fine. It arrived nicely packaged, with a great deal of cardboard and other eco-friendly packaging and precious little plastic.

Underneath, the design is also fairly innocuous, but I was a tad worried by the corner brush, which has just one brush arm, instead of the usual three-to-five I am used to seeing. The roller head had rubber fins – which tend to be good on solid floors – as well as carpet-friendly brushes, but there was only one roller, and some of the better robots I have tested have two.

The base station (which measures H14 x W12 x D9 inches) only caters for dirt; there’s no water reservoir. But the bin capacity is generous and it’s easy to see when it’s getting full due to the vertical strip of transparent Perspex. It also clips in and out easily, as does the filter in the other side of the base station – a large, foam creation that needs cleaning under the tap once a month. I appreciated that the base station has a plastic disc the size of the robot, which is to protect wood floors from getting soggy when the mop attachment is in place.

On the top of the Shark Matrix Plus are just two buttons, one to power on/off and the other to start/stop, everything else is done by the app, which I will cover in depth lower down this review.

• Design score: 4 out of 5

Shark Matrix Plus 2-in-1 review: app

• Good mapping skills
• Scheduling and spot cleaning
• No multi-maps

To get started, I just had to pop on the side brush, plug in the base (then charge the robot for six hours) and download and connect the app. Do make sure you only connect it to a 2.4 GHz wi-fi network, I wasted about half an hour trying to connect it to my 5 GHz but that was my fault for not reading the instructions. In my defense, the instructions that come with the Shark Matrix Plus are not particularly enlightening, but are enough to get you set up (if you read them properly).

Compared to other robots I have tested, the SharkClean app is pretty basic and rather annoying. Hopefully there will be upgrades as Shark gets its head around robot life. It is basic in that it doesn’t allow you to schedule specific rooms or more than one clean per day, it doesn’t let you choose how the robot cleans (perimeter-first works best for our pet-filled home), and you can’t change the power levels once it’s working.

The annoyances generally iron out, but they can be frustrating. Mainly I found it slow to connect, which is annoying when you’ve decided to pop a clean going before you jump in the car. The cleaning reports didn’t always record/save, and I found it hard to move between actions. For example, if it was returning to base, I couldn’t get the app to show me the maps so I could plan the next job. Sometimes the map disappeared completely, or the app froze, and once or twice it wouldn’t acknowledge that we had a robot in the house at all!

The other downer that didn’t bother me, but might you, is that it will only map one floor. I am happy to use my cordless vacuum upstairs (where it lives) and have never been one for carrying robots up and down levels but if you want to use the robot on multiple floors, you’ll only be able to map one of them.

It's not all bad news though. The actual map the Shark Matrix Plus created was perfect first time and was created really quickly – in less than 10 minutes. I also found it very easy to add rooms, as well as rugs (to prevent wet carpets in mopping mode) and create a schedule for each day (to coincide with the school run).

• App score: 3 out of 5

Shark Matrix Plus 2-in-1 review: performance

• Good at corners and edges
• Quieter than advertised
• Mopping a bit basic

Using in vacuum mode

The Shark Matrix Plus comes with the regular vacuum cleaning insert installed, which has a small bin and filter inside and automatically empties its payload back at the mother base. I needn’t have worried about the measly single-arm corner brush, as it did an excellent job of getting dog dander and dust bunnies out from along the skirting boards and corners of cabinets etc.

Shallow enough to get under all our freestanding furniture, including the sofas and the kitchen kickboards, the Shark Matrix Plus also had no problem climbing onto chunky rugs or over the wooden thresholds between rooms, many of which have thwarted less agile robots.

Being largely open view with level flooring throughout the ground floor, our home is the perfect setup for robotic cleaning. But I was also hugely relieved to discover the Shark Matrix Plus could hoist itself over the legs of the lounge chairs in our kitchen, which have grounded every other robot I’ve ever hosted. This meant I’d have to lift the heavy chairs onto the sofa out of the way or go and rescue the robot and restart it mid-clean. I was delighted the Shark Matrix Plus glided over them with barely a grunt.

Another genius benefit of the Shark Matrix Plus is its ‘Matrix’ cleaning system, which essentially means it cleans back and forth and then up and down, in a grid-like pattern. The difference between that and a simple back and forth clean was significant. You can only use Matrix if you’re doing one room, presumably because it takes more time and power, but I liked to use it on the living room because that’s our only carpeted room and the results were much better.

You can also Matrix Clean a 5’ x 5’ area without the app, which is great for random spills. You need to carry the robot to the spot, then press and hold the start button for five-to-seven seconds until it says, ‘starting spot clean’.

I used this spot cleaning function to test the Shark Matrix Plus on an area of flour and oats. As you can see from the photo gallery above, the results were average. It cleared most of the flour, except in the grooves between the wood planks, and left just a few crumbs of oats. I still had to get out my cordless to finish the job, and I only used the low power setting to get the flour out of the grooves, suggesting that my cordless is better than the Shark Matrix Plus, even on its lowest power setting. Annoyingly, there was quite a lot of flour and oats left around the base station when it returned to empty the bin, and I had to get the cordless to clear that up, too.

As I work from home, I really appreciated how quiet the Shark Matrix Plus was, my decibel meter recorded just 46 dB in the low power mode, which is the one I mostly used on our hard flooring. This is similar to the sound of bird calls or in a library and was much lower than Shark’s official rating, which presumably has to include the bin emptying sound level. Being so quiet meant I could have it running around in the background when working, except during Zoom meetings, without feeling distracted or annoyed. It is indeed much louder when emptying the bin into the base station, but it’s very short-lived.

On the point of bins, I did love having the extra capacity of the base station as my usual robot requires daily emptying. However, it fell far short of the 60-day emptying schedule advertised – I found two weeks was about the longest I could leave it.

Our carpets and rugs are all low pile (upstairs, too), so I can’t tell you how well the Shark Matrix Plus might manage on a thick pile rug, but it did well on our wool carpet in the living room and the jute rug in the kitchen. I mean, it’s hard to say how deep down the clean was, but I didn’t feel the need to get another vacuum out afterwards.

Using in mop mode

Before mopping, I first had to add rug zones to my map, so it didn’t soak the rugs or carpets. This was pretty easy to do, until it got to the exploration run, which you’re meant to do to make sure you have got the rug placements right. The Shark Matrix Plus wandered close to where I’d marked the kitchen rug, and then went a bit mad, zig-zagging all over it. I decided I didn’t have the patience to worry about it and sent it back to base.

Once the module is in, the Shark Matrix Plus automatically recognizes it is mopping and – this bit is amazing – it will vacuum and mop at the same time . I’ve only tested one robot vacuum that claimed to mop and was disappointed to discover that it really couldn’t. That other model barely made my floors damp, let alone cleaning them, and because it had to go round and vacuum first, it also took a lifetime to do a terrible job.

By contrast, the Shark Matrix Plus did a much more thorough job and you could see trail marks where it had been, which showed decent coverage. The pad oscillates over the surface, which presumably picks up more dirt than just sliding along. The mop pad was reassuringly dirty when it was done, too. As most of our ground floors are real engineered wood flooring, I also appreciated that the Shark Matrix Plus didn’t flood them in water as that would almost certainly damage them. Oh, and it also managed to find, and skip past, the rugs.

In truth, the results didn’t compare with what can be achieved with an actual mop, and it didn’t get very close into the corners or skirtings, but it was good enough for a mid-week freshen up before getting the mop and bucket out on Saturday morning.

• Performance score: 4 out of 5

Shark Matrix Plus 2-in-1 review: battery life

• Plenty of power
• Charges quickly

The battery life ranges from about 85-110 minutes, depending on what power mode you have it on. This isn't anything to rave about, but it only needed one quick recharge when covering our ground floor in max power, which took around 131 minutes (including charging time) to do all six rooms and the hallway (which the Shark app says is 112sq m worth of cleaning). Once recharged, it would return to the spot it left off and merrily resume cleaning.

The official Shark stats say the battery takes six hours to fully recharge, but I found it only took about three so perhaps it wasn’t completely empty whenever it went back to base. Either way, I had no complaints about the battery life.

• Battery score: 5 out of 5

Should you buy the Shark Matrix Plus 2-in-1?

Buy it if…

You hate emptying bins

As I own a robot that requires emptying every single day, I can assure you that you need a self-emptying base station.

You have hairy housemates

The roller is anti-hair-trapping and it works well. There were a few hairs around the middle after a month’s testing but nothing like what I’m used to seeing wrapped around my robot’s rollers. It also has proper HEPA dust filtration.

You want zero drama

Of all the robots I have tried, this was the least needy. It never once got stuck or lost, nor sent me a distress message to say it had ‘fallen off a cliff’ (when in reality it was just straddling the doormat).

Don’t buy it if…

Tech stresses you out

The app is glitchy and unreliable and not terribly informative, either. There may have been swearing…

You want to clean upstairs, too

The mapping currently only covers one floor level, so choose wisely.

You’re OCD about dirt

Like most (possibly all) robots, the suction power isn’t comparable to manually operated vacuum cleaners – use it for daily maintenance cleaning, then do a ‘proper’ vacuum on the weekend.

How I tested the Shark Matrix Plus 2-in-1

• I used this vacuum in my own home for a month
• I vacuumed carpets and vacuumed and mopped hard floors
• I recorded the sound levels using a Decibel Meter App

I used the Shark Matrix Plus 2-in-1 to clean the ground floor of our four-bed, Victorian family home for a month, using it every day on all our downstairs floors, which include terracotta and porcelain tiles, engineered timber, wool carpet and three rugs. The total area is around 120sq m.

I checked out every feature on the app, and did Spot cleans, Matrix cleans and mopping runs. I liked being able to pick specific rooms, so I could just get the main kitchen and hallway done quickly, but mostly I scheduled the robot to work while I was out of the house, so I could arrive home to nice clean floors throughout.

During testing, I used the decibel meter on my iPhone to monitor noise levels and conducted a test to see how the vacuum coped with flour and oats on hard flooring.

As part of my job as a journalist specialising in kitchens and bathrooms, I’ve been reviewing vacuum cleaners for publication both online and in print for several years now. I’ve tested lots of robot vacuums, and currently own an Anker by Eufy Hybrid X8 , which I like well enough, but I liked the Shark Matrix Plus more.
