Eureka's new flagship robot vacuum can see water spilt on your floor

At the Consumer Electronics Show in Las Vegas earlier this month, Eureka unveiled its latest flagship robot vacuum, the J15 Max Ultra. And we were there to see it. This model builds on the tech of previous iterations – and fixes some limitations from earlier models – with some thoughtful, problem-solving features.

What is the J15 Max Ultra?

The J15 Ultra is an upcoming mopping robot from Eureka. It’ll be the brand’s top-of-the-line model.

When will be the J15 Max Ultra be available to buy?

Eureka’s new flagship robot vacuum will be released in the US in June 2025. As yet, we don’t know its UK launch date.

What will the J15 Max Ultra cost?

The US launch price will be $1,299. This compares well to rival flagships from other brands. Dreame’s flagship X50 Ultra, which has a similar feature set, will have a US launch price of $1,669.99.

We’ll update this article when we know the J15 Max Ultra’s UK launch price.

What features does the J15 Max Ultra have?

What we like about the J15 Max Ultra is that it feels thoughtfully designed, with tech created to tackle robot vacuum limitations and minimise the annoyances – dust left in corners and hair tangled around the brush bar – that robot vacuum owners face.

Here are some of its best features:

IntelliView 2.0

Eureka’s IntelliView system, already available on models prior to the J15 Max Ultra, uses AI to help the robot to identify spills – and distinguish between wet and dry mess. When it encounters a spill, it employs an intensive cleaning process over the entire area.

But users found a flaw in the system: the robot found it difficult to spot clear liquid spills or, for example, milk on white flooring. Enter IntelliView 2.0, which has cracked this problem.

In uses both an infrared vision system and an FHD vision sensor. This gives the robot two ways to see and by using AI to analyse these images, it can essentially see texture, which lets it spot the water and other transparent spills that previous models would miss.

22,000 Pa suction

A couple of years ago, top-flight models had 8,000 Pa of suction, so it’s incredible how quickly this has ramped up. This level of suction should leave hard flooring spotless and give carpets a decent clean as well.

SweepExtend and ScrubExtend

Eureka

One of the biggest bugbears of robot vacuums has always been that they don’t clean right up to edges and into corners of rooms. Eureka’s fix for that is an extendable side sweeper that the brand has cunningly named SweepExtend. This is matched by a mop pad, which also extends to wet-clean right up to walls. Guess what? It’s called ScrubExtend.

Speaking of the sweeper, its called the DragonClaw, thanks to the claw-like design (more like fingers than a wheel) that’s made to ensure that long hair won’t get wrapped around it, as it does with a traditional sweeper.

FlexiRazor

In fact, removing tightly-wound hair from various parts of a robot vacuum must be the most unpleasant part of maintenance. The J15 Max Ultra has another feature to help minimise this task: the FlexiRazor, a set of metal teeth, cuts away hair from the brush roll.

ObstaCross

Eureka

Recently, a number of brands have addressed the problem of raised thresholds and small steps between rooms, which traditionally made areas of the home inaccessible to robots. Roborock’s Qrevo Curv can now cross thresholds of up to 4cm, while the Dreame X50 Ultra Complete can handle a step of 4.2cm, or combined steps of up to 6cm, thanks to its extendable robotic legs.

Eureka’s robot has extending wheels that allow it to cross a single step of up to 1.18in (2.99cm) or combined steps of 1.57in (3.98cm).

We’ll be reviewing the J15 Max Ultra to see how well these features work in day-to-day life. But in the meantime, take a look at our top recommendations from models we’ve already reviewed in our round-ups of the best robot vacuums and the best cheap robot vacuums.
