REDMOND RV-R650S WiFi: wet cleaning, smartphone control, UV lamp

Welcome to the site's readers robovac.washerhouse.com! We've received the new REDMOND RV-R650S WiFi robot vacuum for review. The manufacturer's website lists it for $180 with a discount, placing it in the mid-price segment. For this price, the manufacturer offers a robot equipped with a gyroscope for navigation, controlled by both a remote control and a mobile app, capable of mapping the room, wet cleaning, and even disinfecting the floor with a UV lamp. Let's take a look at the REDMOND RV-R650S WiFi's design, how it cleans, and, most importantly, whether it's worth the money. So, let's get started.

Equipment

First, let's look at the robot vacuum cleaner's package contents. The box includes a charging base, a power adapter, a separate dust bin, a dust bin lid, and a separate water tank with a microfiber cloth attached. Additionally, there's a spare cloth, a remote control, an instruction manual, a quick start guide for connecting the robot to the app, two spare side brushes, a spare filter, and a cleaning brush for the dust bin and center brush.

The only missing component is a motion limiter. It's also worth noting that batteries are not included with the remote control. They must be purchased separately. Otherwise, all consumables and accessories are included.

Appearance

Now let's take a look at the robot vacuum cleaner itself. It's round and gray.

The height is only 77 mm, so the robot is able to clean under low furniture.

A water tank is installed out of the box. It holds 300 ml of liquid. A pump is visible inside, which electronically regulates the water flow. The cleaning cloth is attached to the bottom with Velcro.

The tank also has a compartment for collecting dry debris during wet cleaning. The robot can sweep the floor without vacuuming, which is important. The dust compartment holds 60 ml.

Instead of a water tank, you can install a dust collector with a capacity of 450 ml.

The dust collector is equipped with a dual filtration system consisting of a mesh filter and a pleated filter. The dust collector also houses a motor, so it cannot be washed with water.

Let's turn the robot over and look at its underside. We can see a UV lamp positioned in front of the central brush, which disinfects the surface. But we can't say how effective it is, or even if it's effective at all.

There are two side brushes, three-pronged, with bristle tassels. A bristle-petal turbo brush is installed in the center.

Overall, this robot's design is familiar; we've already reviewed similar models. For a mid-price segment, the build quality and materials are quite acceptable.

Functional capabilities

Let's move on to an overview of the REDMOND RV-R650S WiFi's features. First, we'll show you how to control the robot using the remote control. The top button turns the robot on and off. Below that are two buttons: one for automatic cleaning of the entire accessible area and one forcing the robot to return to its base. Below them is a joystick for manual control of the robot vacuum cleaner and a start/pause button in the middle.

Below the suction power control button, there are three levels. Below that, on the left, is a button for local cleaning, and to the right of that, a button for perimeter cleaning.

Now let's look at the app's functionality. First, you need to install it on your smartphone; the instructions include a QR code for quick download. After installation, the app asks you to scan the QR code on the robot itself. After that, you need to connect the robot to Wi-Fi. Follow the prompts; there's nothing complicated about it.

Now that the robot is connected, let's look at the app's main functionality. We launched a guided tour, and here's how it mapped the entire house. It's not exact, but the layout and geometry of the rooms are consistent. The gyroscope can't do much more than that.

Below the map, we see data about the last cleaning: area covered, battery percentage, and time spent cleaning.

Below are the robot vacuum's control buttons. These include start/pause, suction power adjustment, water level adjustment when the tank is installed, forced return to the base, and cleaning mode selection. Automatic, spot, wall, and manual modes are available.

Additionally, you can enable or disable voice notifications in the robot's settings. You can also change the robot's name, set up a cleaning schedule by selecting the time and days of the week, choose the units of measurement, share control with other users, and update the firmware if a more recent version is available.

These are all the features. They're basically standard for robotic vacuum cleaners with a gyroscope. Incidentally, it also supports control via Yandex.Alice, which might be an interesting solution for some.

Testing

And most importantly, we'll show you how the REDMOND RV-R650S WiFi removes noise and test its main features.

Watch our detailed video review and robot vacuum cleaner test:

Navigation

Let's start with navigation. We placed obstacles in the form of a chair and a box within a single room to test the robot's route planning and ability to clean the entire accessible area.

The REDMOND RV-R650S WiFi moves in a serpentine motion. It covered the entire area, completed the perimeter, and then cleaned around the box and three of the four chair legs. Afterward, it returned to its base to charge. Its navigation worked perfectly. It cleaned 10 square meters in 20 minutes. That's not particularly fast, but that's standard for robots with a gyroscope.

We also tested how well the robot would clean the entire available area. In our case, this included five rooms with a total area of ​​approximately 34 square meters. The robot vacuum cleaned every single one. The map isn't precise and there are some errors, but the geometry is correct (see image above). Cleaning the 34 square meters, which it calculated as 31, took almost 45 minutes. Most importantly, there were no uncleaned areas.

Suction power

Next, we tested the robot's suction power. We scattered debris into cracks 2 to 10 mm deep on the test bench. The REDMOND RV-R650S WiFi was able to partially vacuum debris from a depth of 2 mm.

This is a standard feature for robotic vacuum cleaners, and these crevices are the most common in home environments. This robotic vacuum isn't advertised as powerful, so there are no complaints about its ability to vacuum debris from crevices.

Dry cleaning of laminate flooring

We scattered various household debris on the stand. This included wool, hair, ground coffee to simulate dust, cereals, and bread crumbs.

And you can see that it managed to pick up almost all the debris from the floor. There was a small amount left in the corners, due to the round shape of the unit, and some dust along the baseboard. Cleaning quality isn't perfect, but it's above average.

Dry cleaning of carpet

Let's see how the REDMOND RV-R650S WiFi performs on carpet. We scattered the same debris as in the previous test.

You can see that it cleaned the carpet thoroughly, removing any debris, hair, or crumbs. This test was passed successfully.

Wet cleaning

We also tested the floor's ability to remove dirt. We stained the laminate with shoe stains and let them dry for a bit.

The robot vacuum cleaner was able to remove all the dirt, so it did an excellent job.

There's no significant difference in the cleaning performance of the cloth between the minimum and maximum settings, but the robot does wet the cloth slightly less at the minimum water level. The 300 ml tank is sufficient for cleaning over 100 square meters.

Noise level

We also measured the REDMOND RV-R650S WiFi's noise levels in different modes. In floor polishing mode, the noise level did not exceed 57.2 dB, at minimum power it was around 60.5 dB, in standard mode it was around 63.5 dB, and at maximum power it reached 65.5 dB. These are typical values ​​for robots. It's not loud, but it's not particularly quiet either.

Dark spots

We also tested whether the REDMOND RV-R650S WiFi is sensitive to black rugs, detecting them based on differences in height.

Yes, this robot vacuum cleaner doesn't work on black surfaces, like many others. Therefore, if you have black carpets or black tiles, you'll need to cover the height protection sensors if your home doesn't have steps or height differences between rooms.

Obstacle clearance

The final test will show us what kind of obstacles the REDMOND RV-R650S WiFi can overcome. It easily clears 10mm and 15mm obstacles, but it's not always able to clear a 20mm obstacle, although it can manage it. This means it can overcome obstacles up to 20mm.

Let's sum it up

We've thoroughly tested the REDMOND RV-R650S WiFi. Now let's dive into the final analysis. We'll evaluate this robot vacuum across a variety of criteria, taking into account the sub-$200 price point and our test results.

Navigation 8 out of 10. Although the robot can clean within a five-room radius and navigate around obstacles, the gyroscope isn't considered advanced navigation. Because of this, the robot vacuum can't continue cleaning after recharging at the base or zone the room into rooms. Each time, it must reacquaint itself with the room and "mark" the boundaries of the cleaning zone with its bumper. The map is built, but not saved in the robot's memory. At a cost of $150 to $200, gyroscope-based navigation is a standard solution, but not the best. Therefore, we can't give it a top rating.

Versatility 9 out of 10. The robot is suitable for both dry and wet cleaning, and its turbo brush effectively picks up both small debris and pet hair. It can be controlled not only via the app but also with a remote control. Overall, it's suitable for cleaning both hard floors and carpets. One point is deducted for the fact that in wet cleaning mode, the REDMOND RV-R650S can only sweep, not vacuum.

Design and execution 8 out of 10. The robot vacuum cleaner is well-built, but the design of the central and side brushes is quite standard. The top cover isn't resistant to mechanical damage; it was slightly scratched during testing. There's nothing particularly special about the design, other than the UV lamp, the effectiveness of which can only be tested in a lab setting. However, the plastic doesn't feel cheap; for the price, it's a decent option.

Cleaning quality 9 out of 10During the dry vacuum test, the REDMOND RV-R650S WiFi left some debris along the baseboards, but overall, it performed well in dry vacuuming, carpet cleaning, and even scrubbing dirt off the floor. It can pick up small debris, as well as pet hair and fur from the floor. Therefore, there are no major complaints about its cleaning performance.

Functionality 8 out of 10. Due to the lack of advanced navigation, many modern features are unavailable, such as cleaning in selected areas or setting no-go zones in the app. Furthermore, there's no virtual wall included for mechanical movement restriction. However, it can be controlled via smartphone and remote control, allowing you to adjust suction power, water flow level, set up a cleaning schedule, and choose one of three operating modes. This is sufficient for keeping your home clean, especially considering it's in the mid-price range.

Manufacturer support 9 out of 10. Redmond is a very popular company and provides warranty service and support for its products. You can easily purchase consumables and even some spare parts on the website. The app is not proprietary; we've seen it on other robots before, so we can't give it a full score. However, the manufacturer is well-known and trusted, so we're only deducting one point.

Total: 51 out of 60 points

Overall, the REDMOND RV-R650S WiFi is a pretty good value for the money. It's equipped with all the basic features, is well-built, and can automatically keep your home clean. So, we have no real complaints about the robot, and we couldn't find any reason not to recommend it. The website list price is $270 before the discount, which is certainly expensive, but for $180, it's a decent option.
