For an allergy household the important specification is not suction. It is what happens at the moment you empty the machine, and that splits this field cleanly in two.

We have not tested these machines. Everything here comes from published specifications, manufacturer manuals and retailer listings, all cited below. Prices last verified September 21, 2026.
How this is funded: if you buy through a link here we may earn a commission, at no extra cost to you. It does not change which machines we recommend or what we say about them. Full disclosure.
For an allergy household the best machine under $300 is the iRobot Roomba 105 Vac with AutoEmpty Dock: it empties itself into a sealed bag iRobot states traps 99% of allergens as small as 0.7 microns, and it does that for up to 75 days at a time. The reason it wins is not filtration alone - it is that a sealed bag is removed with the dust inside it, so the one moment a vacuum reliably puts dust back into your air never happens.
That is the criterion this page is built on, and it is the one most rankings skip. Suction, mapping and brush design decide how clean the floor gets. Filtration and the emptying method decide what you breathe.

Scores come from the published rubric on How We Pick: suction 25%, navigation 25%, pet hair 20%, running cost 20%, setup 10%. They are editorial judgments about published specifications, not test results.
How we judged this, before the ranking
1. What happens when it is emptied. A machine with a bin releases a small cloud when you tip it out. A machine with a bagless dock does the same thing, less often. A machine with a sealed bag does not - the bag comes out with the dust inside it. For a reactive household this is the difference that matters, and it is why the ranking below is not the same as our general ranking.
2. What filtration figure is actually published. Only two machines here publish a real one. Shark states true HEPA at 99.97% down to 0.3 microns - 0.3 microns is the particle size HEPA testing is defined around because it is the hardest to catch. iRobot states its dock bag traps 99% of allergens as small as 0.7 microns. Everything else on this site says something like four-stage filtration with no number attached, and where no figure is published we score it as unverified rather than assuming it is good.
3. How often you have to handle it. Fewer emptying events means fewer exposures, so dock capacity is an allergy specification and not just a convenience one. The published intervals here run from 60 days to 90 days.
4. Whether hair wraps. A brush bound with hair holds debris in the machine and has to be cleaned by hand, which is another exposure. An anti-tangle mechanism is worth real points here even though it has nothing to do with filtration.
Sealed bag or bagless: the decision this page turns on
Every self-emptying machine solves the same problem in one of two ways, and for most buyers the choice is about money. For an allergy household it is not about money.
A sealed bag costs you a few dollars several times a year, forever. In exchange, the dust that came off your floor goes into a bag that you lift out and drop in the trash without ever opening. A bagless dock costs nothing to run and is the better answer for almost everybody else on this site - but it has to be tipped out, and tipping out a bin of fine dust in your kitchen is precisely the event a reactive person is trying to avoid.
That is why the Shark Matrix Plus sits second rather than first despite publishing the strictest filter figure here. Its HEPA base is genuinely excellent while the dust is inside it. Then you empty it. Our running costs guide does the three-year arithmetic if the money side matters more to you than the exposure side.

Both filtration figures are manufacturer-reported. Not published means the manufacturer states no figure for that model, not that we could not find one.
Why the longest interval is an allergy feature
The Tikom L8000 Plus publishes 90 days on a 3-liter bag, the longest stated interval on this site. Read that as four handling events a year instead of six, on top of never opening a bin by hand. It gives up the published filtration figure and it names no anti-tangle mechanism, which is why it sits fourth rather than first - but if your priority is touching the machine as rarely as possible, it is the one that asks least of you.
The Tapo RV30 Max Plus is the cheapest way into a sealed bag at all, well below the Roomba pairing. Its 3-liter bag is stated at up to 60 days and it adds LiDAR with inertial navigation, which keeps the map straight when a wheel slips. No filtration figure is published for it either.
What a robot vacuum will not do for allergies
It will not clean your air. These machines move along the floor; airborne particles are an air-purifier problem, and no robot vacuum on this site claims otherwise. What a daily floor pass does is stop the reservoir on your floor from building up in the first place, which is a real contribution and a limited one.
It will not deep-clean carpet, where dust mites actually live. That is a weight-and-power limit rather than a price limit - our carpet guide sets out where the line falls. If carpet is the trigger, the honest advice is a robot for daily maintenance plus a proper upright for the deep clean, which our robot versus regular vacuum guide works through.
It will not stop you having to clean the filter. Every machine here has a filter that needs tapping out or rinsing, and that is an exposure event nothing removes. Do it outdoors, or over a bin, or ask somebody else in the house to.
Set it up to help rather than to stir things up
Run it while the house is empty, or at least while the reactive person is out. Any vacuum disturbs settled dust; the advantage of a robot is that it can do that when nobody is in the room.
Give it an hour after the run before you go back in, so anything it lifted has time to settle or be captured.
Put the dock somewhere ventilated rather than in a bedroom. It is the one place in the house where the collected dust lives.
Change the bag on schedule rather than when it is full. A stuffed bag reduces airflow and is more likely to leak dust when handled.
Run it daily on a low setting. Frequency keeps the floor reservoir small, which does more than any single deep pass.
What we could not verify
We have not handled these machines and we have not measured particle counts. Both filtration figures above are manufacturer-reported and neither manufacturer publishes the test method, so they are not directly comparable to each other - 99.97% at 0.3 microns and 99% at 0.7 microns are different claims about different particle sizes. We also cannot tell you how much dust escapes when a bagless base is emptied, because nobody publishes that figure. How we pick sets out the weights behind every score here.
The 105 Vac plus a sealed-bag dock that traps particles down to 0.7 microns. The only machine here that publishes a filtration figure that small.

What it gets right
Bagless and HEPA together - it is the only machine here that empties itself, filters to 0.3 microns, and costs nothing to keep running

Matrix Clean makes multiple passes over one area, which is a real answer to the single-pass problem

What it gives up
No published suction rating of any kind, which on a specification-led site costs it real points
Both headline improvements are quoted against Shark's own previous model, not against the field

Questions people actually ask
+−What is the best robot vacuum for allergies under $300?
The iRobot Roomba 105 Vac with AutoEmpty Dock. It empties itself into a sealed bag that iRobot states traps 99% of allergens as small as 0.7 microns, and the bag is removed with the dust inside it, so you never tip out a bin.
+−Is a bagged or bagless robot vacuum better for allergies?
Bagged. A sealed bag is lifted out and thrown away with the dust inside; a bagless base has to be tipped into a bin, which is the one moment a vacuum reliably puts fine dust back into the room. Bagless is the better choice for running cost, not for exposure.
+−Do budget robot vacuums have HEPA filters?
One machine on this site publishes a true HEPA figure - the Shark Matrix Plus, at 99.97% down to 0.3 microns in its base. Most others describe multi-stage filtration without stating a standard, which we score as unverified rather than assuming it meets one.
+−Will a robot vacuum help with dust mite allergy?
Partly. Daily passes keep the floor reservoir down, which helps. Dust mites live in carpet pile and soft furnishings, and no robot vacuum at this price deep-cleans pile - that still needs an upright, and soft furnishings need washing rather than vacuuming.
+−Does a robot vacuum clean the air?
No. It cleans the floor, and a good filter stops it putting what it collects back into the room. Airborne particles are an air-purifier job, and no machine on this site claims otherwise.
+−How often should I empty a robot vacuum if I have allergies?
Change a sealed bag on the manufacturer's schedule rather than waiting for it to be full - a stuffed bag restricts airflow and is more likely to release dust when handled. If you have a bin rather than a dock, empty it outside.
