This page compares six robot vacuums priced under $300 in the US marketplace. All six are real catalog records from our validation on 2026-08-18, and every price was returned by the Amazon Creators API that day (Creators API, as of 2026-08-18). Three of the six — the ILIFE A30 Pro, the Xiaomi Robot Vacuum E10C, and the iRobot Roomba Plus 405 (G181) — have specifications we extracted directly from the manufacturer's own page on 2026-08-18. The other three are price-only at this stage: we list their prices but make no specification claims about them. This is a spec-based comparison: nothing here implies hands-on testing.

Which robot vacuums under $300 are in this comparison?

The table below lists all six sub-$300 models from our catalog validation. Prices are US marketplace prices returned by the Amazon Creators API during validation on 2026-08-18 (Creators API, as of 2026-08-18). Spec columns show only values we verified on a manufacturer's own page; "Not yet verified" means we have not extracted that value from a primary source — it is unverified data, not missing data.

What is the best budget robot vacuum under $300?

On verified data, the ILIFE A30 Pro at $199.99 (Creators API, as of 2026-08-18) is the strongest all-round pick under $300: it is the only model in this set whose official page states suction in pascals (5,000 Pa), LiDAR navigation with multi-floor mapping, and a self-emptying station rated up to 7 weeks on a 2.5 L dust bag (iliferobot.com, checked 2026-08-18).

If mopping matters more than vacuuming, the iRobot Roomba Plus 405 (G181) at $299.99 (Creators API, as of 2026-08-18) is the pick: its spinning DualClean mop pads with auto pad lift and SmartScrub at 200 RPM are the most detailed verified mopping system in this price band, and its AutoWash dock washes and dries the pads (irobot.com, checked 2026-08-18). The trade-off is suction: iRobot publishes only a relative "70X more intense suction" claim against the Roomba 600 series for this model, with no absolute pascal figure on the page we checked.

How much suction do these budget models provide?

Two of the six publish an absolute pascal figure. The ILIFE A30 Pro states 5,000 Pa robot suction, plus a separate 12,000 Pa cyclone in its self-emptying station (iliferobot.com, checked 2026-08-18). The Xiaomi Robot Vacuum E10C states 3,500 Pa on top gear, measured by Shanchuan Laboratory per the manufacturer's page (mi.com, checked 2026-08-18).

The iRobot Roomba Plus 405 (G181) publishes no absolute figure — only the relative "70X more intense suction" claim versus the Roomba 600 series (irobot.com, checked 2026-08-18). The remaining three models (Roomba 105 Vac, DEEBOT T30C, Shark Matrix Plus) had no pascal value extracted in this pass. There is no industry-wide standard for how manufacturers measure suction in pascals, so treat these numbers as directional rather than laboratory results. Our full breakdown of what pascals do and do not tell you is on our page How Much Suction Does a Robot Vacuum Need?

Do any sub-$300 robot vacuums self-empty?

Two of the six do, on verified data. The ILIFE A30 Pro's station uses a 12,000 Pa cyclone and a 2.5 L dust bag rated up to 7 weeks (iliferobot.com, checked 2026-08-18). The iRobot Roomba Plus 405 (G181) AutoWash dock auto-empties debris for up to 75 days and also washes and dries the mop pads — the manufacturer frames this as four weeks of mopping and pad washing (irobot.com, checked 2026-08-18).

The Xiaomi Robot Vacuum E10C does not self-empty: its dock is a charging dock only (CDZB112) per mi.com (checked 2026-08-18). The Roomba 105 Vac, DEEBOT T30C, and Shark Matrix Plus are unverified on this point in our pass. Our detailed comparison of self-emptying claims across more models is on our page Best Self-Emptying Robot Vacuums.

Which sub-$300 model mops best on the verified data?

The iRobot Roomba Plus 405 (G181) has the most complete verified mop system in this price band: spinning DualClean mop pads, auto pad lift so carpet does not get wet, SmartScrub scrubbing at 200 RPM, and a dock that washes and dries the pads (irobot.com, checked 2026-08-18).

The Xiaomi Robot Vacuum E10C mops with a pad and a smart water tank offering three water flow levels; its runtime in standard mode for vacuum and mop is stated as 110 minutes (mi.com, checked 2026-08-18). The ILIFE A30 Pro offers basic 2-in-1 mopping from a shared 200 ml water tank — verified, but with no pad washing or drying in the station per iliferobot.com (checked 2026-08-18).

How long do these budget models run per charge?

Two of the six publish runtime figures. The ILIFE A30 Pro states up to 180 minutes in silent mode, covering up to 120 square meters (iliferobot.com, checked 2026-08-18). The Xiaomi Robot Vacuum E10C states 110 minutes in standard mode for vacuum and mop (mi.com, checked 2026-08-18).

The iRobot Roomba Plus 405 (G181), the Roomba 105 Vac, the DEEBOT T30C, and the Shark Matrix Plus had no runtime figure extracted in this pass. Runtime depends on mode, floor type, and suction level, so even published figures are best treated as manufacturer maximums under stated conditions.

Who should buy what — and who should not?

If you want self-emptying plus LiDAR navigation for under $200: the ILIFE A30 Pro at $199.99 (Creators API, as of 2026-08-18) is the only model in this set with both verified.

If you mop hard floors and your budget tops out near $300: the iRobot Roomba Plus 405 (G181) at $299.99 (Creators API, as of 2026-08-18) is the mopping pick — but accept that its suction is published only as a relative claim.

If you want a simple vacuum-and-mop with no dock dependency: the Xiaomi Robot Vacuum E10C at $199.99 (Creators API, as of 2026-08-18) works, but do not buy it expecting self-emptying — its dock is charging-only per mi.com (checked 2026-08-18).

If you want the absolute lowest price: the iRobot Roomba 105 Vac at $149.00 (Creators API, as of 2026-08-18) is the cheapest model in this set, but its specs are not yet verified from a primary source — check the product page before purchase.

If you were hoping for the DEEBOT T30C or Shark Matrix Plus: both sit at $299.00 and $299.99 respectively (Creators API, as of 2026-08-18), but neither had verified specs in this pass, so this page makes no specification claims about them.

How we compared these budget robot vacuums

We evaluated each model using:

• current US marketplace price from the Amazon Creators API catalog validated 2026-08-18;
• suction in pascals, only when stated on the manufacturer's own product page and extracted by us;
• self-emptying dock claims (interval, dust bag size) as stated by the manufacturer;
• mop system details (pad type, water tank, wash/dry functions) as stated by the manufacturer;
• navigation method and runtime, only when published on the official page;
• spec verification status per model — verified versus pending.

We did not measure noise or cleaning performance in this pass. The full method is on our page How CompareSmartDevice Compares Robot Vacuums.
