The iRobot Roomba s9+ costs a cool £1,500 – is it worth it?

We put this snazzy, self-emptying robot vacuum cleaner to the test to find out

The iRobot Roomba s9+ costs a cool £1,500 – is it worth it?

The iRobot Roomba s9+ certainly looks the part of a top robot vacuum cleaner. Its sleek rose-gold and black body is chock full of impressive tech. It even empties itself, so you really can put your feet up and let it get on with the chores.

Then again, at a staggering £1,500, you’d expect it to do all the work for you, and look good too.

Robot vacuums can seem like the futuristic chore-saving gadget we’ve all been craving, but only a few prove they can dust-bust as well as conventional vacuum cleaners in our independent trials.

We put the iRobot s9+ through our tough tests to find out if its cleaning power and navigation skills are as mighty as its price tag.

Head straight to the full iRobot Roomba s9+ review to get our official verdict, or read on to find out more about key features and how it compares to iRobot’s other robot vacuums.

iRobot Roomba s9+ – what you get for £1,500

For starters, it looks great. The brushed metal disc on the lid is circled by a ring of white light that illuminates in different patterns to tell you the program stage and when it’s charging.

Self-emptying bin

It comes with a self-emptying bin or as iRobot snappily name’s it: automatic dirt disposal. This is the big-ticket sell on this vacuum.

Robots tend to have the tiniest of all vacuum dust containers. They usually have around a 0.6-litre capacity, compared with around 0.8 litres for a cordless stick vacuum and 2.3 litres for a full-sized vac. This adds up to you having to empty the teeny tiny dustbin much more regularly, slightly negating the convenience of having a robot clean for you in the first place.

iRobot has deftly solved that problem by building a large dustbin into the charging dock, and designing the vacuum to empty itself automatically every time it plugs itself in to charge. This means less effort on your part, and less faffing around with loose dust.

Smart navigation system

The accompanying smartphone app, iRobot Home, offers a suite of impressive features. Not only can you control and customise the vacuum remotely, but its navigation system remembers the layout of your home and can remember up to 10 layouts at once.

This means you can order it to clean specific areas of your home, and it can also be voice-controlled using Alexa or Google Home, making floorcare as easy as: ‘Alexa, clean the living room.’

Conquering corners

It also has ‘PerfectEdge’ technology, designed to ensure dirt lurking in awkward corners is picked up. This uses sensors to recognise walls and edges, and hugs them so that the specially angled side brush can get deeper into corners.

Whole-system filtration

Filtration hasn’t always been a top priority for robot vacuums, but the s9+ puts paid to that, claiming its filtration system is designed to prevent tiny dust particles and allergens such as pollen and mould spores leaking back into your home.

That, combined with the minimal dust-emptying, could be enough to swing it for those sensitive to allergens.

Extra suction on carpets

The s9+ recognises when it hits carpets, and ups the suction for a more powerful clean. As this is traditionally a tougher job, that could be handy. It’s something we’ve seen start to creep in on cordless vacuums such as the Dyson V11 Absolute.

How does it compare to the older, cheaper iRobot Roomba 980?

The older Roomba 980 was the breakthrough robot vacuum for iRobot. It rose to fame partly due to notable appearances in TV shows such as Breaking Bad, Parks & Recreation and Jonathan Creek.

We’re yet to spot the new s9+ on-screen, but iRobot could line it up for a self-cleaning cameo. Keep your eyes peeled.

The first major difference is the price. The older Roomba 980 can be picked up for around £450, less than a third of the price of the new s9+.

As you might expect, it’s also not as smart or as packed with features. You can still programme it to clean at certain times and use Alexa or Google Home to voice-operate it, but it doesn’t empty itself and the mapping system is more basic.

They’re also different sizes. The Roomba 980 is quite compact at only 10cm tall, enabling it to slip under furniture. The s9+ sits even lower to the ground at just 9.2cm high. It is twice as wide as the Roomba 980 at just over 30cm wide though, so tight gaps are more likely to be a struggle.

Should you buy the iRobot Roomba s9+?

It costs a small fortune, but if it cleans your house effectively and effortlessly, this might be a price you’re willing to pay.

Below we’ve listed a couple of the pros and cons we found during testing. For our overall verdict on the Roomba s9+, including how it scored compared to rivals such as the Dyson 360 Eye, you’ll need to head to our full iRobot Roomba s9+ review.

Pros

  • Good at sucking up pet hair – Got a furry friend who likes to moult? Fear not, because the s9+ is deft at sweeping up pet hair. We comb real cat and dog hair into carpets when testing, measuring how much is left over at the end and how long it takes to clear up. The s9+ did a good job of this.
  • Advanced mapping system – Not only were we impressed by the s9+’s ability to remember and clean specific rooms, but we also love how by using the app, iRobot Home, you can set up multiple virtual barriers to restrict where it cleans within those rooms. It’s an incredibly customisable machine.

Cons

  • Ongoing cost of dust bags – You may still be reeling from the s9+’s four-figure price, but unfortunately the impact on your wallet doesn’t stop there. The main dustbin in the charging stand is bagged, which means that when it’s full you’ll need to replace it. The s9+ comes with two dustbags included, but you’ll need to pay around £20 for packs of three once they’re gone.
  • Noise – It’s not crazy loud, but you’ll definitely notice when it enters the room. It’s still much quieter than a conventional vacuum cleaner, though.
