Best Robot Vacuum Under $300

Every listing here is a real deal, not a place-holder, which means the descriptions tell you what the seller is actually offering — including the awkward parts. "Used for one full day and returned, need to be cleaned" is a different proposition from "brand new, ships today," and we treat it that way. Four things decided the order.

• Navigation tier. LiDAR mapping, SLAM mapping, and app-based home mapping all beat a bare bump sensor that reverses off your sofa. It is the single biggest quality difference in this price band and it is visible in the listing title.
• What is in the box. Charging dock, mop pad, extra filters, side brushes. A robot sold "just the body" is not a deal, it is a parts donor.
• Condition honesty. New with a full accessory list beats used-unless-tested. We flag it either way so you know what you are getting.
• Price per unit of capability. A $28 robot that has to be manually repositioned three times a week is worse value than a $95 that maps your home and empties itself back to the dock.

One honest caveat before we start: eBay prices change and vary by seller and condition. We confirmed the numbers on the date above, and some of these are auction-style listings that can move while you sleep. Every price in this roundup was verified on September 29, 2026 — check the live listing before you commit, because a $95 robot that sells out is not going to wait for you to decide.

Two things we deliberately did not do. We did not rank anything on suction figures we could not read in the listing, because sellers quote wildly inflated numbers and the ones that matter are measured in airflow and brush design, not marketing. And we did not exclude used listings just because they are used — a tested used Shark AI with a full accessory set is a better buy than a brand-new no-name robot nobody can service. Condition is a factor, not a disqualifier, as long as the seller is straight with you about it.

More than half of this roundup is used inventory, so it is worth spending two minutes on the checklist that separates a good used robot from a box of expensive plastic.

• Ask for a runtime test. A working robot should run 60 to 120 minutes on most models. Ask the seller to start it on a charge and message you the time it dies. Battery wear is the number one reason used robots disappoint.
• Confirm the dock is included. Several listings here call out the dock specifically, because it is the part most often missing. A robot without its charging dock is a $28 paperweight.
• Count the accessories. Bin, one filter minimum, side brush, remote. A that shows four detachable side brushes, a charging dock and power adapter, a washable HEPA filter, a cleaning brush, a mop cloth, and anti-fall stair sensors is what a complete package looks like — use that as your reference point for what "complete" means on other listings.
• Check the app still exists. Discontinued brands like bObsweep and OKP are the main risk in this category. If the seller's phone is old enough to still have the app, ask for a screenshot of it running.
• Look for the parts story. iRobot, Shark, and ECOVACS all have current replacement parts. A brand nobody stocks filters for is a problem the second the main brush wraps with hair.

Two red flags, in plain terms: a listing that says “selling as is, just the body, currently untested,” and one that says “for parts.” Neither is a deal. Both are the price of a donor machine that you will end up sourcing parts for anyway.

Shark IQ R100 — the best new robot under $300

The is the only genuinely new, full-featured machine in this roundup, listed at $250. The listing describes Wi-Fi app control, home mapping, and Alexa support, in black. Shark is a mainstream brand with replaceable parts readily available, which matters a lot when something stops working three years in.

• Pros: Brand-new condition; home mapping and app control; the most capable navigation in this list; Shark parts are easy to find.
• Cons: At $250 it eats most of the budget; no self-emptying base at this price; you will still need something for edges.
• Price note: $250 as confirmed on our date. New, so it carries a warranty and return rights that the used listings below do not.

What the R100 is really selling is navigation. The listing calls out home mapping and Alexa support, which means it builds a floor plan of your space instead of bouncing around it randomly. In practice that is the difference between a robot you run daily and one that you forget you own because it spent twenty minutes stuck on a dining chair leg. At $250 it is the priciest thing here, but it is also the only listing in the roundup that is new, warrantied, and mapped. That combination does not show up anywhere else under $300 on the listings we pulled.

The honest limitation is that $250 in this category is still entry-plus money. You are not getting a self-emptying base, and Shark's obstacle avoidance at this tier is good rather than excellent — expect it to find a sock eventually. If your household has no pets and mostly hard floors, this is a very sensible spend. If you have pets, keep reading; the used Shark AI below does more of what you actually need for a third of the money.

Shark AI AV2001WD — best value 2-in-1 for pet homes

The is listed at $94.99 used. The description touts intelligent home mapping, AI navigation, and simultaneous vacuuming and mopping using sonic mopping. It vacuums and mops in one pass rather than making you run two devices.

• Pros: Vacuums and mops in the same run; home mapping with AI navigation; the pet-hair positioning means a rubber-style roller rather than bristle hair traps; roughly $155 under the new Shark above.
• Cons: Used condition, so expect cosmetic wear; mopping is a maintenance-light mop, not a deep scrub; no self-emptying dock.
• Price note: $94.99 as confirmed on our date, used, priced against the $250 new Shark IQ — the same brand, a different tier.

Compare that to the new Shark IQ R100 at $250 and the maths gets interesting fast. You are paying $95 for an older generation of the same brand, with a slightly simpler navigation stack, but you are getting the 2-in-1 vacuum-and-mop capability and the pet-hair roller. For a home with a shedding dog and a hard-floor kitchen, the $155 you keep is arguably better spent on replacement filters and a decent cordless stick for the edges — the missing piece the robot will not cover, and which you can find in our under-$150 vacuum roundup.

One thing to plan for with any 2-in-1: the mop pad needs washing roughly every two or three runs, and it should dry fully before you reattach it or you will get a sour smell from the base. That is a two-minute chore per week, and it is the real ongoing cost of the convenience.

iRobot Roomba i3 — the app-and-dock workhorse

The is a used listing at $90. The description notes Wi-Fi connectivity for monitoring and control, and that the included charging dock is part of the package. The i3 is the middle of iRobot's older lineup — smarter than the entry 690, without the self-emptying cost of a j7.

• Pros: Wi-Fi app control; dock included; iRobot's replacement parts and filters are abundant; the cleanest brand-name resale value in the group.
• Cons: Used, and older navigation than a current LiDAR model; no mopping; no self-emptying; older battery may hold less charge than new.
• Price note: $90 used as confirmed on our date.

Shark IQ R100 alternative: the bObsweep PetHair with LiDAR

The is listed at $116.99 used. The description highlights simultaneous localization and mapping in real time, with laser vision for building a map of the surroundings. bObsweep was one of the earliest brands to push LiDAR into affordable robots.

• Pros: True LiDAR mapping at a used price; SLAM builds a real floor plan; strong pet-hair focus; cheaper than the new Shark IQ R100 by more than half.
• Cons: Used, and the bObsweep brand is discontinued so parts and app support are getting harder to find; no self-emptying.
• Price note: $116.99 as confirmed on our date. Scarcity of the brand is the real risk, not the price.

bObsweep PetHair Espresso — budget mapping under $70

The is listed brand new at $69.99, ships today. It is the new-condition version of the mapping tech above, at a price that undercuts almost every mapped robot we found. The espresso color is just cosmetic; the SLAM mapping and Wi-Fi are the draw.

• Pros: Brand new, not a used gamble; SLAM mapping and Wi-Fi at a sub-$70 price; pet-hair roller; ships fast.
• Cons: Discontinued brand, so long-term parts support is limited; budget-tier suction for deep carpet; no mop, no self-emptying.
• Price note: $69.99 new as confirmed on our date — the best condition-per-dollar mapped robot in the roundup.

OKP LIFE K5 — cheapest way into an Alexa-compatible robot

The is a used listing at $90.56, described by the seller as in excellent cosmetic condition and powering on, marketed for pets. Voice-assistant compatibility at this price is unusual and genuinely useful — you can start a clean without opening an app.

• Pros: Alexa and Google Assistant compatible; excellent cosmetic condition per the seller; built for pet homes; tested-and-working framing reduces risk.
• Cons: Used; a random or basic navigation rather than premium mapping; no self-emptying; the OKP brand is not a household name for support.
• Price note: $90.56 as confirmed on our date.

Yeedi K650 — the returned-unit bargain

The is the cheapest properly self-charging robot in this roundup, listed at $44.95. The seller says it was used for one full day and returned, that it is well used and needs cleaning, and notes it was featured by Digital Trends, WIRED, and Reviewed for pet hair. Ships same-next business day.

• Pros: Rock-bottom price for a self-charging, voice-compatible robot; pet-hair focused; that press coverage suggests the hardware is better than the price implies.
• Cons: The seller explicitly says it needs cleaning; one-day-returned means almost no battery health data; you will want to fully clean filters and brush before trusting it.
• Price note: $44.95 as confirmed on our date, the best price per feature in the whole roundup.

Lefant M210P — the $28 starter

The is listed used at $28. The description calls it a sleek industrial-gray self-charging robotic vacuum designed for busy households and commercial spaces, with navigation features. At $28 it is the cheapest real robot we found, full stop.

• Pros: Cheapest genuine robot on this list by a wide margin; self-charging; described as suitable for commercial spaces, so it can take a beating.
• Cons: Budget navigation that will need help in cluttered rooms; used; no mopping, no mapping features worth the name; minimal brand support.
• Price note: $28 as confirmed on our date.

Lefant M201 with docking station

The is used at $49.50. The description highlights Bluetooth connectivity for smart-home integration and that the included charger docking station is part of the deal. Having the dock explicitly included is worth more than it sounds, since docks get lost.

• Pros: Dock included; Bluetooth smart-home integration; clean black finish; about $20 over the M210P for a more complete package.
• Cons: Used; Bluetooth is a weaker integration than Wi-Fi for scheduling; no mopping; basic navigation.
• Price note: $49.50 as confirmed on our date.

ECOVACS Deebot N10 Max — the mid-range mapped compromise

The is listed at $179 used. It sits in the interesting middle of this roundup: a mapped, vacuum-and-mop machine from a brand with an active app ecosystem, for less than the new Shark IQ above. Used at $179 is where a lot of the value in this category hides.

• Pros: Mapping plus mopping in one unit; ECOVACS app is current and supported; a step up in navigation from the sub-$100 machines.
• Cons: Used, so battery and roller wear are unknown; $179 is a lot to commit used without a return window; no self-emptying.
• Price note: $179 as confirmed on our date.

ECOVACS Deebot N30 Pro OMNI — flagship hardware, shipping-damage price

The is a wild card: listed at $20, and the seller says it is new from a unit damaged in shipping. This is a flagship self-emptying, self-washing Omni-style machine at a fraction of anything. It is the highest-upside and highest-uncertainty listing we found.

• Pros: Flagship N30 Pro OMNI hardware — self-emptying and mop-washing — for $20; brand new, never used.
• Cons: Shipping damage is unspecified, so something may be cracked or missing; no functioning history; the base station is a complex part to replace if damaged.
• Price note: $20 as confirmed on our date. Inspect on arrival and use eBay's money-back guarantee.

iRobot Roomba 690 — the parts-grade Roomba bargain

The is used at $49.99, described as a popular choice for households adding a robotic vacuum, with navigation and cleaning capability. The 690 is an older, very common Roomba, which cuts both ways: parts everywhere, but modest performance.

• Pros: Recognizable, widely serviceable brand; abundant cheap replacement parts; around $40 under the newer i3.
• Cons: Oldest navigation in the roundup; no Wi-Fi app, no mapping, no mopping; used battery is the main risk.
• Price note: $49.99 as confirmed on our date.

Here is the short version, with prices confirmed on our date and subject to the usual caveat that eBay prices shift.

• Best overall / best new: the Shark IQ R100-class machine — here, the Shark IQ R100 at $250 — if you want the best navigation and a new-machine warranty.
• Best value for most people: the Shark AI AV2001WD at $94.99, which vacuums and mops and maps, especially if you have pets.
• Best cheap-and-new with mapping: the bObsweep PetHair Espresso at $69.99 new.
• Best for a pet home on a budget: the Shark AI, or the OKP LIFE K5 at $90.56 for voice control.
• Best absolute bargain / most risk: the ECOVACS N30 Pro OMNI at $20, if you inspect carefully on arrival.
• Best bare-bones starter: the Lefant M210P at $28 for a rental or small space.
• Best brand-name resale pick: the Roomba i3 at $90 if you want app control and a serviceable brand.

No matter which you pick, remember the honest bottom line: eBay prices change and vary by seller and condition, and robot vacuum listings in particular sell in waves. We confirmed every figure in this roundup on September 29, 2026. Check the current price, read the condition notes, and make sure the dock, bin, and at least one filter are included before you check out. A robot without its dock is a deal that is not a deal.
