If you’re looking for a new robot vacuum cleaner to buy online, you might come across the S4 Max and wonder “Is it worth the splurge?‘. A hard-working member of the Roborock family, the S4 Max robot vacuum cleaner has been on our wish list for a while due to its excellent pick-up performance and economical price. We’ve researched some of the best robot vacuum cleaners for 2022, and the Roborock S4 Max is a name that crops up time and time again, and with good reason.
Although Roborock has upgraded its lineup with the Q5 series, you can still find the S4 Max robot cleaner online, with a price point as attractive as the specifications of the robot cleaner itself.
Here we take a closer look at what you can expect from the S4 Max robot vacuum cleaner, so you can decide whether to add it to your shortlist.
Roborock S4 Max: at a glance
With an intuitive smart app for easy operation, fast mapping for fast and superior cleaning and a silent performance mode, the S4 Max packs many attractive features.
The S4 Max is designed to fit into your daily routine and is easy to set up and start. It keeps the floors around your house very 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, this probably won’t be an issue if you live in a home where space is tight. But if you’re not sure whether to opt for a freestanding robot vacuum 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 streamlined body measuring H18.9 x W6 x L18.8 inches, the S4 Max can effortlessly glide across floors and pick up dirt, increasing its power where needed. With an impressive suction power of 2000 Pa, it can even last up to 180 minutes on a full charge – 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 performs well in low-light rooms, which is useful if you want to use it after hours.
Roborock S4 Max: price and availability
Roborock has upgraded its robot vacuum offering with the latest Q5 series and has discontinued the S4 Max at its own location.
That said, the S4 Max robot vacuum cleaner can still be found online at a very attractive price, so we understand if you’re wondering’Should I buy the S4 Max?’. Regardless of whether it’s discontinued by Roborock, we think the S4 Max’s smart features and affordable price still make it a very compelling option.
At the time of writing, the S4 Max can be found at Amazon for $299 (opens in new tab)/ £254 / AU$533 and US only. If you’re happy to spend a bit more and want more in-app features, you can buy the Q5 Series starting at $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 easy to use is a plus. It comes with a sleek black case with silver trim, similar in style to the Roborock S6 MaxV. Measuring 18.9 x 6 x 18.8 inches (HxWxD), it’s slim enough to glide around the room and navigate under furniture where possible.
The flip-up bin conceals the 460ml bin and pulls out via a handle for easy emptying. It has a five-spoke rubber brush on the bottom of the unit to catch dirt and debris and direct it to the brush roll for more effective cleaning.
While it doesn’t come with a dock that doubles as a self-cleaning tray, the S4 Max does have a small charging dock in the box. This can be attached to the floor with double-sided tape if you want to fix it to particularly wobbly surfaces.
However, if an auto-empty dock is integral to the type of robot vacuum you want, you might want to take a closer look at the Roborock Q5+ (opens in new tab).
Roborock S4 Max: Performance
With LiDar navigation for accurate and efficient cleaning and automatic carpet detection that cleans your carpets and rugs more thoroughly, the S4 Max has a lot going for it. It has the ability to clean up to four levels of your home which can be mapped onto the companion Roborock app and built into your routine, allowing the vacuum to be turned on and off at convenient times.
To make things easy for you, there are four cleaning modes to choose from, including Quiet, Turbo, Max, and Balanced. The app also tracks which rooms the S4 Max has cleaned and its current location so you know where it’s going.
In terms of performance, it’s not the most powerful robot vacuum cleaner in the Roborock range, but it’s an effective one: it gives you a suction power of 2000 Pa and up to 180 minutes of runtime on a full charge. When it encounters a carpet it automatically goes into boost mode to ensure optimal cleaning performance and a function in the app makes it easy to target specific areas that need cleaning.
Roborock S4 Max: Verdict
Currently on sale for $299 / £254 / AU$533, the S4 Max gives you the high-tech performance you’d expect from a premium robot vacuum cleaner, without the hefty price tag.
While a dedicated auto-cleaning dock (like the one on the Q5+) would be a bonus, the S4 Max has a roomy bin that can hold up to 460ml before you need to empty it. Weighing in at 11.97 pounds, it’s relatively light to pick up and move around if needed.
We think in-app functionality, voice assistant compatibility and automatic carpet detection are all useful features you’d expect and need from a competent robot vacuum cleaner and the S4 Max has all of these and more.
In short, an excellent balance between price and performance makes the S4 Max a valuable contender for anyone looking for a budget robot vacuum cleaner.
