A robot vacuum under $300 still runs while you are home, or while you sleep, and most of the noise advice for robot vacuums still applies. What changes at this price is what you can buy. The self-empty dock mostly disappears. Some robots lose the map. And sales blur the line, because robots that list for $430 or $450 are often sold for less than $300.
We looked for robots with a maker list price of $300 or less, on the maker's own US store, and kept only those whose maker publishes a noise figure we could quote. Four brands sell robots in this band on their own US stores: Tapo, eufy, Roborock and Yeedi. Tapo and eufy print figures in their page text, Roborock prints one inside a product image, and we found none for Yeedi. Our main robot vacuum guide covers every price; this page reads only the cheap end.
Our picks are listed above, with full specifications for each.
How we set the $300 limit
We used each maker's list price, the compare-at price on its own US store, and nothing else. Sale prices move, so they do not decide eligibility. These robots qualify:
- Tapo RV20 Max: $199.99 list, on sale at $119.99.
- Tapo RV30 Max: $239.99 list, on sale at $159.99.
- Tapo RV20 Max Plus: $249.99 list, on sale at $179.99, but out of stock on Tapo's store.
- eufy RoboVac 11S MAX: $279.99 list, on sale at $169.99.
- Roborock Q7 M5: $299.99 list, on sale at $159.99 in white.
Several more expensive robots drop under $300 on sale. They do not qualify here, and we say so plainly so the sale price does not mislead you:
- Tapo RV30 Max Plus: $329.99 list, on sale at $229.99.
- Roborock Q7 M5+: $429.99 list, on sale at $249.99.
- Roborock Q10 S5+: $549.99 list, on sale at $279.99.
- iRobot Roomba 105 Vac Robot + AutoEmpty Dock: $449.99 list, on sale at $279.99. The Roomba 105 Combo Robot without a dock is $319.99 list, on sale at $179.99.
- Shark Navigator Robot Vacuum RV2120AE: $449.99 list, on sale at $279.99.
A sale is a fine reason to buy one of these. It is not a reason to expect the noise or the features of a $300 robot, and in most of these cases the extra money buys a self-empty dock, the loudest part of the system.
Who is missing, and why
ECOVACS. The cheapest DEEBOT in stock with a noise figure on ECOVACS's US store was the T50 OMNI at $389.99 list. The DEEBOT N20 PLUS lists at $549.99, could not be added to the cart when we checked, and prints only a dust collection figure: 82 dBA. Our ECOVACS robot vacuum decibels page lists every DEEBOT figure.
Roborock's other cheap model. The Q7 L5 lists at $249.99, but we found no noise figure in its page text or its product images. Our Roborock robot vacuum decibels page groups every Roborock figure by the mode it describes.
iRobot and Shark. Every Roomba and Shark robot we found lists above $300. The Roomba 105 page we read prints no noise figure, in line with what our main guide found for iRobot.
Narwal and SwitchBot. Narwal's cheapest robots list at $339.99 (Freo X Plus) and $349.99 (Freo S). SwitchBot's cheapest, the K11+, is $399.99.
Yeedi. The yeedi vac and the yeedi vac max both list at $299.99, but we found no noise figure in either page or its images.
Lefant. Lefant prints 55dB, with no setting named, in images for several cheap robots. Its own store prices in euros, and we found no Lefant US store with list prices, so we could not apply the $300 limit.
Levoit. Levoit's US store sells stick vacuums but no robot vacuums.
Makers quote different settings. A Quiet Mode figure is not the same as a standard-mode figure, and neither is the same as a mopping figure. So we group each figure by the label the maker prints, and rank only inside a group. None of these makers states a measuring distance, which is one reason decibel ratings rarely compare across brands.
- Quiet Mode, dB: Tapo RV20 Max, RV20 Max Plus and RV30 Max, 52 dB each.
- Default/Standard, dB: the same three Tapo robots, 55 dB each.
- Balanced, dB: Roborock Q7 M5, 65dB.
- Mop Only, dB: Roborock Q7 M5, 60dB.
- No setting named, dB: eufy RoboVac 11S MAX, 55dB.
Every group holds one brand. So nothing on this page says one brand is quieter than another, and you should be wary of any list that does. The eufy's 55dB and Tapo's standard-mode 55 dB look identical, but eufy does not say which setting its figure describes.
Inside one robot, the gaps are fair to read. Tapo's Quiet Mode is 3 dB below its standard mode. Roborock's Mop Only is 5 dB below Balanced, and our Roborock page explains why mop-only figures run low: the vacuum fan slows down. Roughly every 10 dB sounds about twice as loud, so a 3 dB step is noticeable and 5 dB is clear. For what these numbers mean beside everyday sounds, see our decibel chart.
A caution on Tapo. The three Tapo robots print identical figures in their spec tables and datasheets, and share a 5300Pa suction rating, a 300 ml bin and a 45W robot rating. The figure may describe a shared platform rather than three separate tests. The RV20 Max spec table also lists "Auto Dust Collection: Yes" and a dock suction figure, though the robot ships with a charging dock only; its datasheet has no dock rows. We read that as a copying error on the page, not a change to the noise figure.
What you give up at this price
We list only what the makers themselves say is missing or limited.
The self-empty dock. Of the five robots that qualify, only the Tapo RV20 Max Plus empties itself. Tapo prints no noise figure for the dock, but rates its working power at 650W, against 45W for the robot. The only dock figure we found near this price belongs to a robot that does not qualify: the Roborock Q7 M5+ page prints more than 82 dBA under its dust bag. The others empty by hand: a 300 ml bin on the Tapo robots and 600 mL on the eufy. For a quiet home, that is no loss. A robot without a dock never makes the emptying burst, which our apartment robot vacuum guide treats as the sound most likely to carry through a wall.
The map. The eufy 11S MAX uses what eufy calls "Bounce Navigation", and its spec table says "Wi-Fi Connected: Not supported", with no no-go zones. You set a schedule from the remote. The Tapo robots and the Roborock Q7 M5 map with LiDAR and support no-go zones in the app, so at this price the map is a choice, not a casualty.
Mop lifting. Roborock's own FAQ on the Q7 M5 page says the Q10 series "includes an additional mop module lifting feature", which lifts the mop "when the robot is on a carpet". The Q7 does without it. Tapo describes carpet avoidance instead: "In mopping mode, the robot smartly detects and bypasses carpets based on the map", and its app guide lets you set carpet areas to avoid, move over or clean. Our robot vacuum and mop combo guide covers robots that lift their mops, all above this price.
Deep carpet. Tapo's guide says "Do not use on high-pile or fringed carpets", and Roborock's Q7 M5 manual says "Do not use the product on high pile carpets."
Obstacle avoidance. Roborock says the Q10 series adds a structured light module, "providing better obstacle avoidance than the Q7 series". The Tapo robots list LiDAR as their obstacle avoidance. No robot here claims to recognize pet waste.
The quiet settings these robots do have
Quiet Mode. Tapo is the only maker here that ties a figure to a Quiet Mode: 52 dB. Tapo lists five suction levels and prints figures for two of them, Quiet Mode and Default/Standard.
Carpet boost. All three brands raise suction on carpet automatically. eufy's manual is the plainest: BoostIQ will "reduce the total cleaning time, but increase the noise level. If the vacuuming noise caused by BoostIQ disturbs you, you can disable this feature." Tapo lists a Suction Boost that "Increases suction power while on carpet", and Roborock an "Auto Boost on Carpet". If a rug sits in a bedroom, a quiet run can turn loud when the robot reaches it.
Do Not Disturb. Roborock's Q7 M5 manual says "The default Do Not Disturb (DND) period is from 22:00 to 08:00" and "In DND mode, the robot will not play voice messages." Tapo lists a Do Not Disturb Mode, and its RV20 Max guide says a schedule will not run inside the Do Not Disturb period. The eufy has no app and no DND; it beeps to confirm settings and to report errors.
Keeping a cheap robot quiet
Both Tapo and Roborock say the same thing about unexpected noise. Tapo's guide, under "Abnormal Noise", says "There may be foreign matter entangled in the main brush, side brush, or wheels." Roborock's manual lists "Noise during cleaning" among its troubleshooting entries. Clean the brushes and wheels often, especially with pets.

If you are choosing for a small flat or a bedroom, our pages on keeping an apartment quiet and a quiet bedroom cover the other machines in the room.
Which one for which home
A small flat with hard floors. The Tapo RV20 Max: a Quiet Mode figure, a map and no dock, at the lowest list price here.
You hate emptying bins. The Tapo RV20 Max Plus, if it is back in stock. Run the dock while you are out, since Tapo publishes nothing on how loud it is.
A shedding pet. The Roborock Q7 M5, for its certified anti-tangle brushes. Its figures are for Balanced and Mop Only, not a quiet mode.
No app, no account. The eufy RoboVac 11S MAX, run from its remote. Turn BoostIQ off if it runs while you are home.
How we chose
We listed every robot vacuum on the US stores of Roborock, Tapo, eufy, ECOVACS, iRobot, Shark, Narwal, SwitchBot, Yeedi and Levoit, and checked Lefant's store. We kept robots with a maker list price of $300 or less, opened each product page, read the text inside its product images with character recognition and checked every figure by eye, and read the manuals, quick guides and datasheets each maker links. We recorded each figure in the maker's words, with the setting it names, grouped figures by that label, and ranked only inside a group. Prices are the makers' US list prices on October 6, 2026.
We did not measure any of these robots ourselves. Every figure here is the maker's own, none states a measuring distance, and no maker in this price band publishes a figure for its strongest setting or, apart from the dock power Tapo lists, for its dock.
