Is the PX251 good for pet stains?

Yes. It is aimed at pet accidents and set-in spots, and owners report it pulls up odor-causing residue from carpet and upholstery. Treat fresh stains promptly and use a pet-safe cleaning solution.

How does it compare with the Bissell Little Green?

The SharkNinja offers stronger suction and a wider cleaning path, while the Little Green is lighter and often easier to store. Both are spot cleaners, so neither replaces a full-size extractor for whole rooms.

Does it work on car seats and stairs?

Yes. The 8.5 lb body and hose reach stairs, car interiors and sofa cushions well. The cord means you need an outlet or extension cord near the car.

How much water does it hold?

The tanks are small by design, so expect to refill and empty them several times when cleaning a large area. For a few spots or one flight of stairs, one fill is usually enough.

What comes in the box?

The cleaner, a hose and a scrubbing nozzle for upholstery and carpet, plus a sample cleaning solution in most kits. Check the listing for the exact attachments included.

Do I need special cleaning solution?

Use a solution made for carpet extractors and dilute it as the label says. Household detergent foams too much and can leave residue that attracts dirt.
