You can now buy the excellent Roborock Qrevo Edge 2 Pro on sale. It's more worthwhile than other models

The end of the holidays means morning rush, muddy shoes in the hallway, and evenings when no one wants to pull out the vacuum cleaner. Roborock responds with an autumn sale offering discounts of up to 40%, but the most interesting item doesn’t have the highest percentage. It’s the **Qrevo Edge 2 Pro** robotic vacuum cleaner, which you can buy for **19,824 CZK** instead of the recommended 30,499 CZK until September 21st. Besides the price list, I also went through the footnotes on the manufacturer’s website, because that’s where you’ll find out what the marketing numbers mean for your home floor.

When the Pro is cheaper than the model below it

The Qrevo Edge 2 Pro has been sold in the Czech Republic since February and has an average customer rating of 4.3 out of 5 on Alza. A 35% discount from the recommended price of 30,499 CZK means a saving of **10,675 CZK**. While it could be found cheaper in some stores in recent months, for about 25,000, the sale price is still several thousand lower even compared to those offers. So you still save a lot.

More interesting is the comparison within the family. The Qrevo Edge 2, which launched in July and is positioned one step lower in the lineup, is currently selling on Alza for **21,499 CZK** without a discount at the time of writing. The more feature-rich Pro is now **1,675 CZK cheaper** than the model that was supposed to be its more economical alternative. You don’t see a reversed price list like this every day.

On Alza, you can apply the discount with code **ALZADNY35** in the cart, or by clicking the “Buy with code” button directly on the product page. The promotion is also running in the Roborock e-shop.

Under the couch with the turret retracted

The Edge series is based on one idea: a robot with a full-fledged LiDAR that fits under low furniture. Regular robots carry the sensor in a fixed turret on their back, but the Qrevo Edge 2 Pro can retract it into its body, and with a height of **7.98 cm**, it is one of the brand’s thinnest models. In open spaces, the LiDAR stays up and scans the room all around. When the upward-pointing rangefinder detects that there’s no space above the robot, the sensor retracts, and a 100° rear view takes over navigation. An upper touch sensor acts as a safeguard against scratches.

I tested the same principle on its younger sibling, the Qrevo Edge 2, this summer, and it works: the robot regularly went under the bed and into places my previous robot had avoided for years. However, before you count on cleaning under a specific piece of furniture, grab a tape measure. If the bottom edge is just barely above eight centimeters, the robot will be operating at the limit of its capabilities.

A chassis that stands on its tiptoes on carpets

Here lies the main hardware difference compared to the Qrevo Edge 2. The Pro has a lifting chassis called **AdaptiLift** with three-wheel steering, which lifts the robot before a threshold. The manufacturer promises thresholds of **up to 4 cm**, but a footnote clarifies that this refers to a two-step threshold composed of 3 cm and an additional centimeter on top. A single threshold can be handled up to 3 cm. Even so, this is more than the Edge 2, which states a ceiling of 2 cm.

The second trick concerns carpets, for which the Pro deploys HyperForce suction with a power of **25,000 Pa**. During operation, the robot adjusts its ground clearance to maintain contact between the suction nozzle and pile up to 3 cm high. According to Roborock’s internal tests, in Max+ mode, it collects 30% more dust on shaggy carpets than the previous generation. The catch is that dynamic carpet cleaning must be manually enabled in the app.

When vacuuming alone or in a mode where it cleans carpets first, the robot leaves the mops detached in the station. Compared to merely lifting them a few millimeters, this is a more reliable solution, especially for higher pile, which a lifted mop could still brush against.

The mop applies pressure only when asked

The pair of rotating mops spins at up to **200 revolutions per minute** and presses against the floor with a force of up to **12 N**. However, both maximums apply only under certain conditions. The mops reach maximum RPM only with extreme water flow in their dedicated mode, and full pressure only with the “Deep Cleaning” function manually enabled for stubborn dirt or stains. During regular mopping, the robot operates more economically, which makes sense – you don’t deal with dried coffee in the kitchen every day. For comparison, the Edge 2 states a pressure of 8 N.

The robot extends towards walls and into corners using FlexiArm technology, which allows both the side brush and the mop to extend beyond the round body’s outline.

Against hair and pet fur, the Pro uses the same pair as the Edge 2: the DuoDivide main brush and the FlexiArm Arc curved side brush, which, according to the manufacturer, can handle strands up to 40 cm long. From my summer test of the Edge 2, I can add my own experience – after a week of operation, I didn’t have to untangle a single hair from the brush.

The station heats water up to boiling point

The multifunctional 3.0 Hygiene+ station determines whether you’ll praise the robot after a month or blame it for a musty smell. It washes the mops with water at temperatures of **up to 100 °C** and dries them with air at **55 °C**. For clarity: the hundred degrees, according to the manufacturer’s note, refers to the water in the station’s dispensers at normal atmospheric pressure, not the mop surface. Compared to the Edge 2, whose station heats water to 80 °C, this is still twenty degrees more.

The station handles the rest of the maintenance itself. It refills the robot with warm water, adds cleaning solution, and vacuums dust into a bag that, according to the manufacturer, lasts up to **65 days**. It also washes its own base with hot water, which can be entirely removed. Furthermore, during washing, it monitors how dirty the mops are: it extends the washing time accordingly, or sends the robot to mop dirtier areas again.

However, account for space. The station measures **38.1 × 47.5 × 48.8 cm** (W × D × H), so it won’t fit into a narrow gap between a cabinet and a wall. Allocate space near an outlet for it before ordering.

Where the younger Edge 2 has an advantage

To complete the picture: the Qrevo Edge 2 is a few months younger, and it shows in places. Its Reactive AI system, according to the manufacturer, recognizes over **280 types of obstacles**, while the Pro states over 200, even though both combine an RGB camera with structured light. The Edge 2 also already supports the Matter standard for smart home connectivity, whereas for the Pro, the manufacturer’s page still states that support will arrive via an update.

However, the Pro puts more hardware on the other side of the scale: the AdaptiLift chassis, dynamic carpet cleaning, 12 N pressure instead of 8 N, washing at 100 °C instead of 80 °C, a cleaning solution dispenser, and, according to available data, a larger battery (6,400 mAh compared to 5,200 mAh). Both have the same suction, 25,000 Pa. At current prices, the choice is simple: for less money, you get more hardware. After the promotion ends, however, the price ratio will likely reverse, and then it’s worth considering whether high thresholds and carpets are even an issue for you.

If you want more, or something different

For those who want even more, the flagship **Saros 20** is available in the same promotion. With code ALZADNY30, it costs **25,899 CZK** instead of 36,999 CZK, which is about six thousand more than the Qrevo Edge 2 Pro. For the extra cost, you get suction up to 36,000 Pa, StarSight Autonomous System 2.0 navigation, and the AdaptiLift 3.0 chassis, which, according to the manufacturer, can handle two-step thresholds of 4.5 + 4.3 cm. The body height remains 7.98 cm. Saros makes sense primarily where there’s a threshold at home that the Edge 2 Pro cannot cross.

The wet-dry vacuum cleaner **F25 Ultra** is an entirely different category. A robotic vacuum cleaner is suitable for regular maintenance, but spilled juice or a crushed roll under a child’s high chair needs to be cleaned up immediately, not at a scheduled time. The F25 Ultra vacuums and mops simultaneously, uses steam up to 100 °C for dried stains, and hot water up to 86 °C for grease. After cleaning, the roller self-cleans with steam and dries with hot air. With code ROBR30, it costs **13,293 CZK** instead of 18,990 CZK. Note that the discount for it is only valid until Sunday, September 13th.

Who the Qrevo Edge 2 Pro makes the most sense for now

The Qrevo Edge 2 Pro is not the newest robot in Roborock’s lineup, and the highest discount in the promotion doesn’t belong to it. However, for 19,824 CZK, you get a body under eight centimeters, a chassis for two-step thresholds up to 4 cm, mops with 12 N pressure, and a station that washes with water up to 100 °C and dispenses detergent itself. It will be most appreciated by households where tiles alternate with carpets, dust has accumulated under furniture for years, and no one wants to deal with mop maintenance. The fact that it’s now cheaper than its more modestly equipped sibling is an added bonus. The promotion is valid until September 21st.
