If you want to buy a new robot vacuum cleaner to buy online, you might come across the S4 Max and wonder ‘Is it worth spending?🇧🇷 As a hard-working member of the Roborock family, the S4 Max robot vacuum has been on our wish list for some time due to its excellent picking performance and great value price. We’ve explored several of the best vacuum cleaners for 2022, and the Roborock S4 Max is a name that comes up again and again, and for good reason.
Although Roborock has updated its lineup with the Q5 series, you can still find the S4 Max robot cleaner available online, priced as attractively as the robot cleaner’s specs themselves.
Here, we take a closer look at what you can expect from the S4 Max robot vacuum so you can decide whether to add it to your list.
Roborock S4 Max: at a glance
With an intuitive smart app for easy control, quick mapping for fast and superior cleaning, and a silent performance mode, the S4 Max packs in plenty of attractive features.
Designed to fit into your daily routine and simple to set up and start, the S4 Max does a great job of keeping your home’s floors clean. It works on carpet, laminate, vinyl or real wood and comes with the tools you need to keep your home free of dirt, dust and dander.
While it doesn’t have a self-cleaning dock, that’s unlikely to be an issue if you live in a home where space is tight. But if you’re not sure whether to opt for a standalone robot cleaner or one that comes with its own self-cleaning dock, you might want to read our feature comparing the Roborock S4 Max vs Q5 Plus (opens in new tab)🇧🇷
With a sleek A18.9 x L6 x L18.8-inch body, the S4 Max can glide effortlessly across the floor, picking up dirt and boosting its power when needed. With an impressive 2000Pa suction power, it can last up to 180 minutes on a full charge – which is more than enough time to have a cup of tea and watch your favorite TV show.
LiDar technology makes the S4 Max accurate and efficient when traveling around your home and accurate when navigating obstacles. It also works well in rooms with low light levels, which is useful if you want to use it after hours.
Roborock S4 Max: price and availability
Roborock has updated its robot vacuum offering with the latest Q5 series and discontinued the S4 Max on its own line of websites.
That said, the S4 Max robot vacuum can still be found online at a very attractive price, which is why we understand if you’re wondering ‘Should I buy the S4 Max?’. Despite being discontinued by Roborock, we think the S4 Max’s smart features and affordable price still make it a very attractive option.
At the time of this writing, the S4 Max can be found at Amazon for $299 (opens in new tab)/£254/AU$533 and US only. If you want to spend a little more and want more in-app features, you can buy the Q5 Series for $399. (opens in new tab) /£338/AU$712.
Roborock S4 Max: design
Looks aren’t everything, but the fact that the S4 Max is sleek and simple to use is a plus. It comes with a sleek black body with a silver finish similar in style to the Roborock S6 MaxV. At 18.9 x 6 x 18.8 inches (height x width), it’s slim enough to glide across the room and navigate under furniture wherever possible.
Its flip-up bin hides the 460ml bin and can be pulled out by a handle for easy emptying. It has a five-spoke rubber brush on the bottom of the unit to collect dirt and debris and direct it to the brush roller for more effective cleaning.
While it doesn’t come with a dock that doubles as a self-cleaning wastebasket, the S4 Max does have a small charging dock included in the box. This can be secured to the floor with double sided tape if you want to secure it in place on particularly shaky surfaces.
If, however, a self-emptying dock is an integral part of the type of robot vacuum you want, you might want to take a look at the Roborock Q5+ (opens in new tab)🇧🇷
Roborock S4 Max: performance
With LiDar navigation for accurate and efficient cleaning and automatic rug detection that gives your rugs and carpets a deeper clean, the S4 Max has a lot to offer. It has the ability to clean up to four levels of your home that can be mapped on the accompanying Roborock app and incorporated into your routine to have the vac come and go at convenient times.
To make things easier, there are four cleaning modes you can choose from, including Silent, Turbo, Maximum and Balanced. The app also tracks which rooms the S4 Max has cleaned and its current location, so you know where you’re going next.
Performance-wise, it’s not the most powerful vacuum cleaner in the Roborock range, but it’s effective – offering 2,000 Pa suction power and up to 180 minutes of runtime on a full charge. When it comes across carpet, it automatically goes into boost mode to ensure optimal cleaning performance, and an in-app feature lets you target specific areas that need cleaning with ease.
Roborock S4 Max: verdict
Currently on sale for $299 / £254 / AU$533, the S4 Max delivers the high-tech performance you’d expect from a premium robot vacuum cleaner, without the hefty price tag.
While a dedicated self-cleaning dock (like the one you find on the Q5+) is a bonus, the S4 Max has a large bin that can collect up to 460ml before you empty it. At 11.97 pounds, it’s relatively light to pick up and move if needed.
We think in-app functionality, voice assistant compatibility, and automatic carpet detection are useful features you’d expect and need from a competent vacuum cleaner, and the S4 Max has all of that and more.
In short, an excellent balance between price and performance makes the S4 Max a worthy competitor for anyone looking for a great value robot vacuum cleaner.
