OEM vs third-party parts: what matters?
Both kinds of part can work well. The useful question is not who made it, but whether it fits your exact model and is built well enough for the job.
Start with fit
A listing should name your exact model or part number. Treat vague wording such as fits many robots as a prompt to check dimensions and connectors.
What to compare
- Pack size and price per part.
- Materials and stiffness, especially for brushes and mop pads.
- Seller details and return terms.
- Whether the part affects your warranty.
Choosing
Wear parts such as brushes, filters, and bags are often easy to compare. For batteries and anything that carries power, read the listing carefully and prefer sellers who state the exact model.
