Models either use replaceable batteries (commonly AAA) or a built-in rechargeable battery. Product listings typically state whether batteries are included or need to be inserted by the user.
They’re usually marketed for finished, sealed hard floors and multi-surface cleaning—commonly listing wood, laminate, tile, marble and other sealed or finished floors.
Different models use different motorized actions: some have a motorized roller that scrubs sealed hard floors, others use dual rotating pads that spin rapidly, and several advertise pad micro‑scrubbers for deeper cleaning.
Many product details advise against using them on unfinished, oiled, or waxed wood boards and on non‑sealed tiles. Several listings also note that carpet is not recommended.
Common features include a large swivel or pivoting head for reaching under furniture, a locking mechanism for edge/baseboard cleaning, and compact, lightweight designs that make it easier to access tight spaces.
Spray systems vary: some models use dual nozzles or a built‑in spray button, others offer pouring spouts or a branded 'smart spray' system, and a few include a removable or refillable solution tank.
