What's the best filter cleaning and replacement schedule for my Marta MT-1361 vacuum?

[DeLena]

To keep your Marta MT-1361 vacuum cleaner running its best, pay close attention to the filter. The user manual suggests washing the filter whenever it appears dirty. For optimal performance, it's generally recommended to replace the filter after about 100 hours of vacuuming. A full plastic filter also needs washing. Here are some key maintenance tips: Avoid using a washing machine or electric heater to dry the filter; always air dry it completely before reinstalling. Clean the vacuum's exterior with water and mild soap; avoid harsh solvents. Prevent water from entering the vacuum cleaner. Always use the Marta MT-1361 as directed in the manual and only with recommended attachments to extend its lifespan.
