Roborock S5 Review

The Roborock delivered one of the best performances of the entire group.

Navigation

The Roborock dominated this test, failing to get stuck in any of our trials and flitting in and out of the narrowest and most confined areas of our testing setup with ease. This robot also had the uncanny ability of immediately finding its way out from underneath furniture the moment it finished cleaning.

This robot also had absolutely no issue at all finding its way back to the dock, regardless of if it was sent home when it was in the same room as its docking station or if it was in a different room.

This robot continued its stellar performance in our last two tests, driving under low furniture with ease and traversing high-contrast flooring without the edge detectors triggering any false-positives.

Home Coverage

This robot cleaned the entirety of our furnished room, never shying away from the more confined spots, like under the legs of our fake dining room table and chairs, always venturing into them to clean. The Roborock would essentially clean everywhere it could physically fit, compared to being too fearful to venture into the more cramped spaces like other models.

This robot easily cleans multiple rooms of your home and will happily pause cleaning to return home, recharge, and automatically resume cleaning if necessary in the process. The Roborock also has one of the most effective spot cleaning processes that we have seen. For a normal spot clean, it covers about a square, about 30 sq. ft. in area, doing a decent job cleaning.

However, the Roborock also affords you the opportunity to initiate the spot clean through its mobile app. You can select up to 5 zones in the cleaning map of your home and the number of passes, ranging from 1-3, you would like the robot to complete and can send it on its way remotely. This is probably the best spot cleaning function we have seen to date from any of these products and is the perfect way to have the robot quickly and conveniently clean areas of your home that are perpetually dirty.

Unfortunately, this robot doesn't include any sort of barrier to prevent it from cleaning unwanted areas. You can purchase the roll of magnetic tape separately, but this isn't our favorite method of cordoning off an area to keep it from being cleaned, finding the virtual wall or app-based methods to be much more convenient.

Carpet Cleaning

First, we ran each robot in our robot pen to see how well it cleaned along the edges of a room and in the corners. The Roborock finished its cleaning pass of the pen quite quickly and actually cleaned quite close to the walls — for a circular robot. It did get a little hung up in the corners, leaving small wedges that measured up to 5" in diameter.

Next, we tested out how the Roborock did at collecting fine particles, using flour as our test mess. This robot didn't do particularly well, delivering a rather below-average performance. It left a decent amount of flour behind on the low-pile carpet. We didn't test on the medium-pile carpet, as that task would exceed the capabilities of almost all of these products and isn't really what they are designed for.

This model redeemed itself when we moved on to the medium-sized debris, easily collecting practically all of the rice from the low-pile carpet, leaving only two grains behind, and tying with a few other vacuums for the top performance in this test. It did a little worse with the fluffier carpet, leaving a little over half a teaspoon of rice behind, dropping it to a tie for third place overall.

The Roborock followed a similar trend for our other medium-sized debris test: oat collection. It again gave one of the best showings we have seen on the low-pile carpet, with only a single oat eluding it. However, it did absolutely abysmal on the fluffier carpet, leaving a ton of oats and oat particles behind, giving one of the worst performance of the bunch.

For our final test, we tested the Roborock with some larger objects to pick up: mini-wheats. It didn't do particularly well with this assessment, with the odds of it successfully collecting the cereal pieces being very hit or miss, on both types of soft flooring. It got about half of the pieces we laid out on the flat carpet and about a third on the fluffier carpet.

Hard Surface Cleaning

This robot started off with an alright performance in our edge cleaning tests, leaving about a 4" wide strip of leftover debris along the edges of the robot testing pen. It struggled a little more in the corners, leaving a slightly wider wedge of material remaining.

There was also a bit of residual debris trapped in the undercarriage of the robot and around the main extractor. Performance dropped considerably in our next challenge, where we tasked the Roborock to clean a section of hardwood laminate floor. This vacuum delivered one of the worst showings out of any products that we have seen, leaving tons of residual flour behind and spending most of its time squeegeeing it around, rather than actually cleaning it. It lacked the cleaning power to extract any flour that had fallen between the boards as well.

This robot did quite a bit better at collecting rice, leaving hardly any residual mess behind, but its performance dropped again when tasked with collecting oats or mini-wheats.

This robot didn't really fling the oats about, it simply just didn't really pick them up, even when driving right over them. It also lacks the clearance to drive over larger objects, like mini-wheats, pushing them around instead.

Pet Hair

This product did better on the fluffier, medium-pile carpet, but still only collected about 13% of the total hair. It got about 7% on the low-pile carpet, making the Roborock a bad bet if you are primarily concerned with cleaning up pet hair.

Smart Connect

This robot features a companion mobile app that lets you adjust the suction, track accessory life, manually drive the robot around, and view a cleaning map of your home.

We found the WiFi connection to be quite reliable, but it was a little difficult to get this device set up as an Alexa skill. It also is not currently compatible with Google Home or Apple Home smart ecosystems. You can also configure a schedule on the app, as well as initiate a spot clean or send the robot home on either the app or on the robot itself.

Value

While this robot is excellent at navigating your home and decent at cleaning, it still is a bit pricey if you are shopping on a budget.
