The Best Budget Self-Cleaning Litter Boxes Under $400 (2026)

A Litter-Robot costs about $600–800. You don’t have to spend that to stop scooping. Several boxes under about $400 have good independent reviews and keep the cat’s way out open while they clean. The catch is that the sticker price is only part of the bill. A $100 box that needs $24.50 trays can cost more over five years than a $390 one that takes ordinary clumping litter.

We haven’t tested these boxes ourselves. This guide is based on maker specs, Amazon listing text and independent testing, mainly by WIRED, Tom’s Guide and cats.com, and we name the outlet whenever a test result appears. Prices are typical street prices from dated sources, so check today’s price.

The shortlist

*Our default assumptions: the lowest typical box price, maker-priced liners or trays, and 10 lb of clumping litter per cat per month at $0.57/lb. Where we couldn’t confirm a brand’s bag price, we use Whisker’s $1-per-liner price as a stand-in, so these are estimates.

Box price vs. running cost

The chart shows the five-year cost for one cat for every box we track, budget and premium.

Two patterns stand out. First, the cheapest boxes to buy are among the most expensive to own. PetSafe sells ScoopFree trays at $73.49 for three, about $24.50 each, and says one lasts about a month for one cat. That’s roughly $290 a year, so the trays pass the Classic’s $100 price within about four months. The 6-pack ($139.99) trims the per-tray cost a little. With two cats, a Chewy answer says a tray lasts 10–15 days, which doubles the bill.

Second, boxes that take ordinary clumping litter cost about the same to run whatever their price. Dr. Elsey’s Ultra (40 lb for $22.99 at Chewy) is the litter our model uses, and bags are cheap. Run your own numbers in the cost calculator.

Our picks

PETKIT PuraMax 2: Best under $400

The PuraMax 2 is the box we’d buy if $400 is the ceiling. WIRED calls it the best option for most people. PETKIT says its anti-pinch design keeps the entrance open during rotation, and cats.com confirms the drum doesn’t turn fully. It has 11 safety sensors, works with clay, tofu and mixed litters, and WIRED found its triple odor control kept the box smelling neutral.

The trade-offs: a small entry that WIRED’s 17-lb cat found cramped, no litter-level sensor, and an app WIRED found cluttered with ads. Cats.com rated it 3.8/5. About $390–400. Check the PuraMax 2 price, or see how it compares with Whisker’s flagship in Litter-Robot 4 vs PuraMax 2.

Lesure Open-Top: Best under $300

The Lesure Open-Top is WIRED’s best budget pick. Setup took WIRED under five minutes and its cats took to it easily. It has a 16 × 20.5 in open top, six infrared safety sensors and an app with scheduling and a child lock, and it works with any litter by swapping the sifter.

The low sides mean WIRED vacuumed daily, and the app is poorly translated. The Amazon listing gives 18 lb in its headline and 15 lb in its FAQ, so treat 15 lb as the limit, and it isn’t for kittens under 6 months. One warning sign: WIRED’s price box showed it at Wayfair as “70% off $834,” an inflated reference price. Judge it on its roughly $250 price, not the discount. Check the Lesure price.

Neakasa M1: Best open-top under $400

The Neakasa M1 is rated for cats from 2.2 to 33 lb, has Kitten Mode for smaller kittens, and holds 11.23 L of waste, up to 14 days with one cat per Neakasa. Tom’s Guide’s cats used it 51 times in a week, more than any other box in that test. The base M1 runs about $360–380, and the M1 Lite about $332, without the bottom gate or mat.

The open top scatters litter. WIRED didn’t recommend the original M1 because of controversies over safety, faulty sensors and counterfeit models, and its open-top pick is the pricier M1 Plus. Neakasa has published its own warning about fake M1 listings, so buy from Neakasa’s storefront. Check the Neakasa M1 price, and read our open-top guide.

PetSafe ScoopFree SmartSpin: Lowest running costs

In our model the SmartSpin is the cheapest box to own over five years, at roughly $780 for one cat. It takes any litter, PetSafe rates it for cats up to 25 lb, and its liners list at $17.99 for 25. WIRED says it works surprisingly well.

It relies on a weight detector alone, sits 12 in off the floor, and WIRED says it feels “kinda cheap.” Keep auto-clean off until a kitten is at least 2.5 lb and 6 months old. About $340–400. Check the SmartSpin price.

PetSafe ScoopFree Crystal Classic: Cheapest to buy

The ScoopFree Classic is the lowest entry price: about $100 on sale at PetSafe, $140 regular. A rake sweeps an open crystal tray, and PetSafe’s safety sensors let it run only when the cat isn’t in the box. Nothing encloses the cat.

It’s designed for cats up to 15 lb, has no app, and works only with ScoopFree trays. PetSafe says to keep it unplugged until a kitten is 6 months old. It’s a good fit for one small cat that already likes crystal litter. Check the ScoopFree Classic price, and stock up on ScoopFree trays. The app version, the Crystal Smart, costs about $186–300.

Budget boxes to approach with caution

ELS PET Orbitie

The Orbitie is a hooded globe with a 12 × 12 in opening for about $260–290. WIRED’s two cats took to it almost at once, but its first unit was faulty and logged phantom alerts up to 36 times a day, the bin filled about every other day with two cats, and litter in the gears needed a monthly teardown. ELS PET publishes no minimum cat weight we could confirm. It does have a 90-day money-back guarantee, per WIRED. If your budget reaches about $390, the PuraMax 2 is the safer buy.

Furbulous Self-Packing

We don’t recommend the Furbulous (about $320–360). Cats.com gave it 3.3/5 with 1/5 for construction, found it very loud at first and then unwilling to scoop, and says its door-and-scoop design could trap a cat if the sensors failed. One owner reported that happening.

Don’t save money on safety

Four of our five picks are confirmed to keep the cat’s way out open while they clean: the Lesure and Neakasa M1 are open-top, the ScoopFree Classic uses a rake on an open tray, and the PuraMax 2’s entrance stays open while the drum turns. We couldn’t confirm the same for the SmartSpin, which relies on a weight detector alone. WIRED won’t recommend boxes that close completely during cleaning. Before you buy, check your cat’s weight and age against the maker’s minimum: 3.3 lb for PETKIT and Lesure (plus 6 months for Lesure), 2.2 lb for Neakasa, 2.5 lb and 6 months for the SmartSpin, and 6 months for ScoopFree crystal boxes. The safety checker does it for you.

Ways to spend less

• Compare with the maker’s own price. Ignore inflated “list” prices.
• Buy from the brand’s storefront, especially for the Neakasa M1.
• Use the litter you already buy. The PuraMax 2, SmartSpin and Lesure take ordinary clumping litter, so you aren’t locked into proprietary refills.
• Check the return window. A box your cat refuses is expensive at any price. WIRED notes ELS PET offers a 90-day money-back guarantee; check the terms for any box before you buy.
• Stock up on consumables such as trays, bags and filters when they’re on sale. See the accessories page and our Black Friday deals guide.
