The original RoboVac 11 from Eufy went on to become one of the best-selling robot vacuums of all-time – even today, it is still available for sale and doing well. When the going is good, it makes sense to capitalise, and the Eufy RoboVac 11S Max follows hot on its heels with a smaller form factor, reduced charge time, BOOSTIQ technology and the same great cleaning power that made its predecessor such a hit. Read on to discover whether the upgrade and slight increase in cost gives it a chance of the same success.

Key Features

  • Successor to one of the most popular robot vacuums of all time
  • Low profile for even more expansive cleaning
  • Remote control
  • 0.6L dust box for more cleaning between emptying
  • 3-point cleaning system to tackle all sorts of dirt and dust across surfaces
  • Quieter than its predecessor at just 55db – around the same as a microwave

The Eufy RoboVac 11S MAX has arguably the toughest act to follow in the relatively short history of robot vacuum cleaners. The original RoboVac 11 ranks among the best-selling individual robot vacuum models ever made, and it continues to go strong in the sales rankings across multiple retailers. Eufy clearly felt that it was time to change things up and used the years of experience gathered since the predecessor’s launch to tweak one of its flagship models for the growing robovac audience.

Not much has changed visually, although the black, spherical nature of robot vacuums meant that Eufy was unlikely to attempt to reinvent the aesthetic wheel. The brand logo has been moved to the centre of the device with a blue power button taking its place towards the top of the unit. While it looks the same, you’ll soon notice the difference if you are upgrading from the previous model. Both models weigh in at 2.6kg, but one of the main reasons to make the change is the smaller form factor found here. The RoboVac 11S MAX may sound bigger, but at 7.2cm tall it cuts 0.6cm off the height of the original. While that does not sound like much, it can potentially make even more of your floor accessible under units and other furniture.

Another significant improvement is in noise levels. The 11S MAX comes in at 55 dB which ranks it among the quietest robot vacuums on the market. As noted in the feature coverage, this model makes about as much noise as a microwave when in operation, and that will sound like a significant improvement to anyone that is already familiar with some of the older models out there.

Suction power has not been compromised to achieve that reduction in noise levels. Upon release, Eufy billed this device as boasting their strongest ever suction power. Coming in at 2,000 Pa in ideal conditions, the 11S MAX is a truly powerful bit of kit that outdoes many of the most popular models like the iRobot Roomba 671, which comes in at a relatively paltry 600 Pa. Given that we consider the cleaning on that unit as being fantastic, this Eufy model leaves it in the dust and rivals models far outside its price range.

Whether comparing to the Roomba or anything else, a major consideration for those seeking the best robot vacuum cleaner for their needs is connectivity and this is where the 11S MAX falls down somewhat – just as with the first RoboVac 11. It is not completely bereft of accessories in this space, and does come with a remote control that runs on a pair of AAA batteries. As an infra-red remote, it requires the user to have a line of sight to the robovac and essentially saves bending down to hit the button and not much else. For some, this will be perfectly adequate, but with other automatic vacuum cleaners out there that can be activated from the other side of the world if required, it can be a limiting factor for some.

In the average-size home, the Eufy will have both floors taken care of without the need for charging in between. It lasts for 100 minutes in standard use and takes between 10 and 15 minutes to clean the average room. That means it will only potentially start to struggle towards the end of a second floor in most cases. When the job is done, it will dutifully return to its based and commence charging automatically, ready to go again.

If you use the 11S MAX regularly, then the dust box should be more than capable of surviving several uses. At 0.6L, it is pretty standard and those that have had the pleasure of owning a robot vacuum cleaner previously will find their experience in this area familiar.

Somewhat impressive is that in spite of the lack of an app, there is a timer on the 11S MAX, and so while you cannot set it to come on directly from the train on the way home, if you stick to a schedule you can still come home to clean floors.

Eufy RoboVac 11S MAX – Pros and Cons

  • Lower profile enables the 11S MAX to reach areas other robovacs cannot

  •  Impressive run time of almost 2 hours for a standard clean

  • Remote control for easy activation within the same room
  • No mobile app or smart functionality

  • Relatively slow to charge compared to models from other manufacturers

  • Not suitable for high-pile carpets and rugs

Eufy RoboVac 11S MAX – The Verdict

Following the success of the first Eufy RoboVac 11, we came into this review confident that the manufacturer would know exactly what they were doing with the 11S MAX. They are a big name and rival iRobot’s Roombas in popularity, and this was always likely to be a fantastic release. We appreciate the fact that they have not attempted to reinvent the wheel with this model. At its core, this is still the Eufy RoboVac that owners and admirers know and love, but it is genuinely better than the model before. Suction power has increased yet the body has got smaller. The IR remote remains as a core feature. Would we upgrade from the original immediately? Not quite. However, if you need a replacement for the original or feel that an upgrade is due, this is the natural choice.


Eufy RoboVac 11S Max Review

Of course, not everyone reading this review will have used the Eufy RoboVac 11 before – or indeed any robot vacuum for that matter. Your concerns centre around quality and value for money, among others. The good news is that the Eufy RoboVac 11S MAX is an excellent robot vacuum in its price range. We would reiterate that there are models out there with superior connectivity but if manual operation and a remote control are all you need, the rest of the specs are fantastic. This model is not the fastest in the world to charge, but suction power, speed and capacity are three real-world highlights that catapult this one into consideration.
