Does it come with a battery and charger?

That depends on the kit. Some versions are sold as tool-only for people who already own ONEPWR batteries, so check what the box includes before buying.

Can it clean a whole room of carpet?

It is built for spots and upholstery, not wall-to-wall cleaning. The small tank and battery runtime make it slow for large areas; a corded full-size extractor is better for that.

What surfaces can I use it on?

Carpet, rugs, stairs, car seats and upholstery are the intended targets. Test an inconspicuous area first on delicate fabrics.

Do I need Hoover's cleaning solution?

Hoover pairs it with its own solution, and using the matching formula is the safe choice. Other low-foam carpet solutions generally work, but heavy foam can be hard to extract.

How long does the battery last?

Runtime depends on which ONEPWR battery you use and the mode. Expect enough for spot jobs rather than a full room; a spare battery extends a session.

Is it good for pet accidents?

Yes, it is a common use. The hose and tools reach into upholstery and tight spots, and the dirty tank is easy to rinse, though urine odors may need an enzyme treatment afterward.
