Black+Decker BR151
Black+Decker BR151 (Refurbished/Clearance) - Occasionally found right at $49.95 refurbished, it offers basic vacuuming (and even a rudimentary mop function) backed by a recognizable hardware brand rather than an anonymous generic label.
Gemini
Eufy RoboVac 11S
Used Eufy RoboVac 11S (with dock, remote, and a healthy battery) — This is a reasonable simple hard-floor maintenance bot under $50 when bought locally or from a returnable listing, but it is old-school random-navigation hardware and battery condition is the entire purchase.
