How much should a robot vacuum cost? What each price band buys
Roborock’s cheapest robot vacuum lists at $299.99 and its most expensive at $2,599.99. Climb the ladder one step at a time, and follow the money.

On paper, the two versions of Roborock’s Q7 M5 robot vacuum are the same machine. Both map your home with a laser, both carry the same suction rating, and both drag a mop with three water-flow levels. The base model lists at $299.99. The Q7 M5+ lists at $429.99.
The difference is the station in the box. The M5+ ships with what Roborock calls the RockDock Plus, which empties the robot’s bin into a bag that “lets you clean for up to 7 weeks,” by Roborock’s own internal testing. The cheaper robot gets a dock that charges it and does nothing else.
So the extra $130 buys one thing: you stop emptying the bin. Few price comparisons are that clean. Further up Roborock’s US lineup, which tops out at $2,599.99, each step changes the robot and the dock at once, and the money is harder to trace.
What does each step up buy you, then? Some steps take a chore off your hands. Others change the robot itself, down to which sofas it fits under. And the list prices don’t hold still. In late September, the most expensive robot on the ladder was selling for less than the one below it.
A laser map and a charging dock
The base Q7 M5 is the plainest setup in the lineup. A 360-degree laser rangefinder maps the rooms, the robot cleans, and it drives home to a dock whose only job is charging. You tip the bin out by hand, and nothing at this price washes the mop for you.
What the higher bands add
The next step, the Qrevo 2 Pro, is listed at $799.99, $370 more than the M5+. It doubles the Q7’s suction rating and adds structured-light sensors that, in Roborock’s words, “detect and avoid everyday obstacles.”
Its two spinning mop pads ride on an arm that “automatically extends around walls, corners, and furniture legs,” and they detach by themselves when the robot heads onto carpet. After each run, the dock washes the pads and empties the bin into a self-sealing bag. A second chore comes off your list: rinsing the mop.
The Saros 10R doubles the price again, to a list price of $1,599.99, and this time most of the change is in the robot. It stands 3.14 inches tall, about two-thirds of an inch lower than the Qrevo 2 Pro. Under your bed or sofa, that decides whether it gets in at all.
The lower body comes with a new navigation system, the StarSight Autonomous System 2.0, and a dock that empties the robot and washes its mops, as the Qrevo’s does. The suction gets an adjective where the cheaper robots get a figure in pascals, so you can’t set the 10R beside them by number.
At the top sits the Saros Z70, listed at $2,599.99. It keeps the 10R’s low body and its navigation, and adds the OmniGrip, a folding arm with five axes of movement.
So what does the last $1,000 buy? Mostly the arm, which Roborock pictures tidying as the robot goes: “Socks? Toward the closet. Sandals? Toward the entrance rug. Crumpled tissues? Toward the Store Box.”
One maker’s price ladder

| Roborock Q7 M5+ | $429.99 | RockDock Plus with 2.7-liter bag | Automatic bin emptying |
| Roborock Qrevo 2 Pro | $799.99 | Mop-washing dock with self-sealing bag | 20,000 Pa, structured-light obstacle sensors, spinning mops that detach for carpet |
| Roborock Saros 10R | $1,599.99 | 10-in-1 Multifunctional Dock 4.0 | 3.14-inch body, StarSight Autonomous System 2.0 |
| Roborock Saros Z70 | $2,599.99 | Multi-functional Dock 4.0 | Five-axis OmniGrip arm |
The costs after checkout
Every dock that does a chore needs supplies. Six replacement bags for the Qrevo and Saros docks run $25.59, and Roborock’s floor-cleaning solution is $18.99 a bottle. The charge-only Q7 M5 uses no bags. Filters and brushes wear out on any robot, docked or not.
Paying more doesn’t lengthen the warranty. The Q7 M5, the Qrevo 2 Pro and the Saros 10R each come with one year of limited coverage. For the Saros 10R, Roborock sells more: $89.99 for one extra year, or $129.99 for two.
What the price tag leaves out
You may never pay a list price at all. On September 25, 2026, Roborock’s US store showed every robot vacuum in its collection on sale. The Saros Z70 was $999.99, less than two-fifths of its list price and $100 under the Saros 10R.
A list price, then, tells you where a robot sits on Roborock’s ladder and what hardware each step adds. The price on a given day can put that ladder out of order. That week, the robot with the arm cost less than the robot without one.
So how much should a robot vacuum cost? In Roborock’s line, the bottom rung buys the map and the cleaning. Each step above it buys a chore off your hands, sharper sensing, a lower body or an arm. No list price on the ladder says how many years of app, cloud service or software updates come with the robot.
Most smart devices leave that out. In November 2024, FTC staff found that 161 of 184 smart products they surveyed gave no support duration or end date on the maker’s website.
Owners of a Neato D8 found out what that costs. The D8, a laser-mapping robot announced in 2020, listed at $700. When Vorwerk, which owned Neato, began phasing out its cloud in October 2025, the saved map and the no-go zones went with it. The robot still vacuums when someone presses its button.
