Welcome to Vacuum Wars! Today, I want to
compare three of Roborock's most popular robot vacuum mop combos: the Q REVO, the
S7 Max Ultra, and the S8 Pro Ultra. I own all three and have put them through extensive
tests over the past few months. In this video, I'll go over their similarities and differences,
and give you my opinions about which one I would recommend and why. So, check the links
in the description and let’s get started! First, let’s discuss the basics. The Q
REVO is the least expensive of these three, and the S8 Pro Ultra is the most expensive.
They all come in two different color options, black or white, typically sold at the same
price. One quick note is that the S7 Max Ultra has replaced the S7 Max V Ultra, which seems to
have been discontinued. The new S7 Max Ultra is primarily different because Roborock did away
with the camera and obstacle avoidance system, opting for a cameralist structured light system
like on the Q REVO and S8 Pro Ultra instead. All three models are very similar and proficient
at basic tasks like picking up various types and sizes of debris on hard floors and carpets.
They all have similar hardware for vacuuming, including an adjustable brush housing and a single
side brush for sweeping. The more expensive S8 Pro Ultra does have two main brush rollers,
whereas the others only have one. However, in our tests, we didn't find this to
be much of an advantage for the S8. The S8 Pro Ultra also has slightly more suction
power according to Roborock. All three have advanced mopping functionality but differ
slightly in their approaches. For example, the Q REVO has two spinning brushes that also
apply downward pressure, while the S7 Ultra and the S8 Pro Ultra use a single flat mopping pad
that vibrates as it applies downward pressure. The S8 Pro Ultra has two places on the pad
that vibrate, whereas the S7 only has one. All three also feature mop pads that
automatically raise when the robot senses carpet. This feature is crucial
because it allows the robot vacuum mop combos to vacuum and mop floor plans with a
mixture of hard floors and carpets in one run instead of two. This design makes them much
more efficient. One difference here, though, is that the Q REVO’s pads lift slightly
higher than the others (7mm versus 5mm). I've tried various ways to test their mopping
ability, including torture tests where they mop dried-on stains like grape juice and coffee.
All three models cleaned up the stains without any problem, which is quite impressive.
Despite using different mopping methods, I can't conclusively say that
one is superior to the others. All three models have Ultra docks, which are
charging docks where the robot automatically empties its dustbin into a disposable bag.
These docks also wash the robot’s mop pads. The S7 Ultra and the S8 Pro Ultra have a
mechanism in the dock that washes the pad, while the Q REVO spins its pads over a
raised plastic surface in the bin. The used water is drained into a dirty water
tank in both cases. You can control in the app how often the robots return to the
dock to wash their pads during each run. All three models also have built-in
heaters that blow warm air on the mopping pads after each run for sanitation
purposes. It’s hard to say which dock design is better as I haven't had
issues with any of them. However, the Q REVO design does have fewer moving
parts, which could be considered an advantage. In terms of mapping and navigation,
they all function similarly, using the same basic LiDAR system to map the
house in about five minutes. They all scored almost identically in various navigation
tests, showing above-average efficiency and coverage. With almost identical battery
specifications, they can all cover about 1,200 to 1,500 square feet per charge, which is
above average for robots in this price range. One area where they differ significantly
is their obstacle avoidance systems. The S8 Pro Ultra, the most expensive model, has
a notably better obstacle avoidance system, followed by the S7 Max Ultra and then the Q REVO. All three Roborocks have very
similar apps and features, utilizing Roborock's excellent app
system. This system is user-friendly and packed with industry-leading features,
such as virtual barriers, zone cleaning, specific room cleaning, multi-level mapping, 3D
mapping, advanced scheduling, and carpet boost. There are no significant feature differences
in the software between these three models. So, what are my recommendations?
It might be hard for the average user to notice much difference between
these products in terms of cleaning or level of automation provided. If the obstacle
avoidance system on the Q REVO were better, it would be an easy recommendation due to
its lower price and high performance. To me, the only advantage of the S8 Pro Ultra is its
superior obstacle avoidance system. The S7 Max Ultra is the middle child, right in between the
other two in every possible way. These three represent the state of the art in the robot vacuum
world, and you can't go wrong with any of them. Check the links in the description
