The Good
Deeper Cleaning: The RoboRock S4 Robot Vacuum provides an intense 2000pa suction which is enough to easily pick off the dust from floors and can even drag trapped dirt from deep inside low-pile carpets — the S4 will leave your floors gleaming and your carpets vibrant. The anti-tangle main brush reduces hair tangling, keeping the S4 running for longer without interruption. It’s also easily detachable so that if it ever gets jammed, you can quickly remove, clean and put it back in place. It also has multiple cleaning modes, so you can choose the right cleanup mode for any given need, along with 4 levels of cleaning power, generating increasing amounts of suction and noise. Choose from Quiet, Balanced, Turbo and Max modes to help you get the best results.
Advanced Technology: A high-precision laser navigation system scans your room at 300RPM, creating a real-time map of your home that is accurate to up to +/- 2cm. This precision mapping and a revamped drivetrain make the Roborock S4 the ideal robot vacuum for complicated homes. Combined with map saving, selective cleaning and easily drawn virtual no-go zones and walls, the S4 can schedule cleans for one room, multiple rooms, or your entire home. Through its WiFi connection, you are able to use its compatible app, giving you total control of the S4 no matter where you are. You can easily start or stop a cleanup, set schedules, change suction levels and more, all through your phone.
Brilliant Design: The RoboRock S4 Robot Vacuum is equipped with a supersized 5200mAh LiPo battery. This gives it enough power for over 150 minutes of non-stop cleaning — more than enough to clean most homes or an area of 2,691sqft. in one session. Its elegant transparent design adds a touch of style, and also makes checking the dustbin easier, taking a glance through the shell is all you need to do. In addition, the S4’s powerful suction doesn’t mean that it’s loud as it treads a delicate balance to give you maximum power for less noise. Now, you can clean with fewer disruptions while watching the TV, listening to your favorite songs or while the kids’ sleep.
Great Extra Features: This robovac cleans right to the edge of stairs and ledges without worry — four onboard cliff sensors, two in front and two in the back scan the ground and stop the S4 from going over edges. When cleaning larger spaces, S4 will clean until its battery is low, then it will automatically return to its dock and recharge to 80% capacity before continuing with the cleanup. Finally, the floating main brush adjusts its height for the perfect clean, dropping close to the ground when cleaning hard floors and rising on the carpet for a thorough clean.
The Bad
Unfortunately, even with a stellar performance, for the most part, the RoboRock S4 Robot Vacuum still has some improvements to undertake. One such area is its cleaning on low pile carpets, which constantly gets an error from the main brush — it gets stuck but upon inspection, there isn’t anything wrong with the brush. It usually gets fixed by hitting the clean button again but this problem makes it unreliable for scheduled cleanings on carpeted flooring and can be disappointing for people who buy this vacuum for that sole purpose.
Other users have complained about the navigation in this robot vacuum. One buyer explained how the S4 didn’t know how to move around objects, and would constantly get stuck when it encountered furniture and other things in the house. As a result, the owner has to clean up every time before using her S4 — at times, it will even get stuck just by coming near small area rugs.
The Bottom Line
Surely, anyone would be disappointed by the flaws outlined above but thankfully, these problems have only been experienced by very few people, while most buyers have enjoyed using this product. All in all, the RoboRock S4 Robot Vacuum would make an excellent addition to your collection of home cleaning tools. This smart and powerful piece of technology may be more expensive than others but it also performs better than most robovacs in its price range.
For the price of $400, you get more than you bargained for: 2,000pa of suction, 4 different cleaning modes, a precision laser navigation system, WiFi compatibility, its very own app, a huge 5,200 mAh LiPo battery, quiet operation and so much more! While there are a few things it can do better, the RoboRock S4 Robot Vacuum does plenty of other things brilliantly. So if you’re in the market for a new robovac and have a bit more to spend, this is a great robot vacuum for you.
