The Roomba 615 is no longer available. We’ve left our review in place for current owners to ask questions in the comments. If you were considering this model, we recommend the Roomba 671.

The iRobot Roomba R615 replaces the original Roomba 615 which saw great success as one of this leading brands’ entry-level model. With the same 3-stage cleaning process as its contemporaries, the R615 has the potential to strike a happy medium between the Roomba 605, iRobot’s entry-level model, and the Roomba 671, which takes the same core design and features and bundles them with enhanced connectivity. With a brand such as this one, the quality of the clean is not in question – but there is plenty more to consider as we do in the full review below.

The iRobot Roomba 600 series has proven to be a smash hit of epic proportions among the robotvac-buying public and it is easy to see why. iRobot has risen through the ranks to stand out as arguably the biggest name in robot vacuum production, and the 600 series has been the reason for many users being delighted with the Roomba brand.

The iRobot Roomba R615 was designed as a replacement for the original Roomba 615 model, which was well-received and easily found itself slotting comfortably into the range. It boasts many of the great features that are staples to the series, such as iRobot’s very own 3-stage cleaning system.

It is due to this unique system that the Roomba’s are able to compete and often beat other robot vacuums which have stronger suction power. Most units in the 600 series, including the Roomba 605 and the Roomba 671, boast 600 Pa suction. Compare this to another unit in the same kind of price range, such as the Eufy RoboVac 11S and its 2,000 Pa suction, and the Roombas might appear weak in comparison.

However, rather than simply sucking up dirt, the Roombas use their excellent brushes to dislodge dirt, ensuring that less power is used on suction to ultimately transfer the dirt into the AeroVac bin. The very same system ensures that the Roomba R615 is suitable for most surfaces, including carpets, laminate, tiles and more, and only the thickest carpets and rugs will see anywhere near disappointing results. The same can be said of virtually any model in this price range, and so it is impossible to complain.

Also common to robot vacuums at this entry-level price point is random navigation. The R615 will not follow a set path and you cannot get it to clean a specific room without manually placing it in there and closing the door. However, the R615 is compatible with virtual walls like the SHM-F Auto Virtual Wall Barrier and while this is an added expense to a relatively basic model, they are a worthy investment if there is any chance of upgrading in the future and, even if not, they massively increase the convenience of any automatic vacuum cleaner.

As noted, the R615 succeeds the original Roomba 615, which itself replaced the iRobot Roomba 620 in the product line-up. The main upgrade through the generations has been to the battery, and this model will last around an hour and a half without requiring a charge and will take approximately three hours to charge to full.

Fans of the connectivity found on higher-end models within the 600 series, like the Roomba 671, and virtually ubiquitous in iRobot’s higher-end robovacs, will be disappointed here. To put things simply, there isn’t any additional connectivity and anyone that purchases this machine will want to get used to the idea of getting up to hit the ‘Clean’ button each time. The convenience of connectivity comes at a cost, and the R615 is notably cheaper than the 671.

Something worth noting about the Roomba R615 is that it is quite a bulky robovac. While the whole idea is that it cleans unsupervised and requires little manual involvement, it is worth keeping in mind that you’ll probably have to take it up and down the stairs fairly regularly. At 3.6 kg, it will not break many backs, but when it is competing with the likes of the Eufy RoboVac 11S, which weighs in at just 2.5 kg, it is always worth keeping in mind.

iRobot Roomba R615 – Pros and Cons

  • Ideal for most domestic surfaces thanks to adjustable rollers and 3-stage cleaning
  • Suitable for pet hair
  • Lasts for around an hour on a full charge
  • No additional connectivity through apps or remote controls
  • Cleaning functionality makes the R615 unsuitable for extremely thick rugs and carpets
  • Randomised cleaning pattern can make for occasional haphazard cleans

iRobot Roomba R615 – The Verdict

Our main question about the iRobot Roomba R615 is whether it represents an upgrade over the Roomba 605, which comes in at a significantly lower price point. In our Roomba 605 review, we noted that the alternative model felt like a 671 without the benefits of Wi-Fi, voice control and an app, and it is easy to feel the same way about the R615. Indeed, all that the R615 has over the 605 is longer battery life – the 605 is reliable for around an hour, and the R615 can go about 30 minutes longer. That makes the size of your floors a consideration, but the £40+ difference in price will also be a factor at these levels.


iRobot Roomba R615 Review

The iRobot Roomba R615 is a very good robot vacuum. This was to be expected, as we are yet to encounter a complete flop on the part of the manufacturer. However, it proves tricky to recommend simply because there are better options out there. Every manufacturer faces competition, but there are better options within the same range. The Roomba 605/606 is cheaper and boasts the same performance with slightly reduced battery life, while the Roomba 671 is only marginally more expensive and brings Alexa support, Wi-Fi and a mobile app into the mix. So, while the R615 is a great robovac in its own right, we would recommend others ahead of it.
