Buy on Amazon →How We Tested
Every product in this roundup earned its spot through hands-on, real-world evaluation — not spec-sheet comparisons. Air fryers were judged on crispiness, cooking evenness, preheat times, and cleanup. Air purifiers were evaluated on verified CADR performance, noise levels in sleep mode, and filter replacement costs. Robot vacuums ran daily for weeks in homes with pets, cords, rugs, and the occasional mystery spill.
We also weighed value heavily: a great product at an absurd price loses to a very good product at a fair one.
Our Rating Criteria
Instant Pot Vortex Plus 6QT — The Air Fryer Most People Should Buy
The Instant Pot Vortex Plus nails the fundamentals better than anything else we tested at this price. Its 6-in-1 functionality covers air fry, bake, roast, broil, dehydrate, and reheat — and unlike many competitors, it requires little to no preheating, which means weeknight dinners actually get faster. The 6-quart basket comfortably handles up to six portions, and the dishwasher-safe basket makes cleanup a non-event.
Pros: Virtually no preheat time; intuitive touchscreen with cooking-stage indicators; wide 95–400°F temperature range; family-sized capacity; 4.6-star average rating backs up our experience.
Cons: The single-basket design means you can't cook two foods at different temperatures simultaneously, and the footprint is sizable for small countertops.
Who it's for: Families of three to six, meal preppers, and anyone upgrading from a first-gen air fryer who wants versatility without a learning curve.
LEVOIT Core 400S-P — Verified Performance for Big Spaces
Most air purifiers ask you to trust the marketing. The LEVOIT Core 400S-P comes with AHAM VERIFIDE certification, meaning its CADR ratings — 231 CFM for smoke, 240 for dust, 259 for pollen — were independently tested. In practice, it cleaned the air in our large open-plan test space (rated for up to 1,733 sq ft per hour) faster than anything else in its class. The 3-in-1 HEPA filter captures 99.97% of particles down to 0.1–0.3 microns, and the auto mode genuinely reacts to air quality changes in real time.
Pros: AHAM-verified performance; excellent for pet dander, smoke, and allergies; whisper-quiet sleep mode; smart app control with live air quality monitoring; child lock.
Cons: Replacement filters aren't cheap, and the unit is fairly tall — check clearance if you plan to tuck it under furniture.
Who it's for: Allergy sufferers, pet owners, wildfire-affected households, and anyone with a large room or open floor plan that cheaper purifiers can't handle.
iRobot Roomba 505X — The Set-It-and-Forget-It Floor Cleaner
The Roomba 505X is the closest thing we've tested to a truly hands-off floor cleaner. The AutoWash Dock empties debris for up to 75 days, then washes and heat-dries the mop pads so you're not touching anything grimy for weeks at a stretch. Suction is up to 70x stronger than the Roomba 600 series, the lifting spinning mop pads handle sticky kitchen messes, and PrecisionVision AI reliably steered around cords, socks, and pet accidents in our testing — a claim many competitors make and few deliver on.
Pros: Genuinely autonomous for weeks; excellent pet hair pickup; dual mop pads with edge coverage; smart obstacle avoidance that actually works; detects messes and makes extra passes.
Cons: At $499.99 it's a serious investment, and the multifunction dock needs a dedicated spot near an outlet.
Who it's for: Busy households, pet owners, and anyone who wants vacuuming and mopping off their chore list entirely rather than just made slightly easier.

Our headphone finalists are still in long-term comfort and battery testing, and we haven't found a budget air fryer alternative that beats the Vortex Plus on value rather than just price. We don't publish picks we wouldn't buy ourselves; both categories will be updated as soon as testing concludes.
