extractor vacuum

The search results show corded electric units, battery-powered cordless models, and at least one air‑powered (pneumatic) oil‑drain extractor.

Corded models list cord lengths roughly from 6 feet up to about 20 feet, while cordless models report runtimes ranging from about 8–20 minutes (some units advertise runtimes near the upper end of that range).

Several models use two‑tank or separate clean‑and‑dirty water systems; some cordless floor washers include self‑cleaning cycles. Typical maintenance recommendations across these products are to empty and rinse dirty tanks after use and to wash or replace filters and clean rollers as instructed.
