Frequently Asked Questions
How often should I replace the iRobot Roomba 694 pre-motor filter?
iRobot suggests replacing the Roomba 694 pre-motor filter Every 3 months under normal use — sooner with pets or daily heavy use. Signs it's due: Reduced suction.
Can I just wash the Roomba 694 pre-motor filter instead of replacing it?
Often, yes — many vacuum filters are washable. Rinse under cold water only (no detergent, no hot water), squeeze gently and air-dry fully — a full 24 hours for Dyson filters — before refitting. Replace it when it won't rinse back to clean, the foam crumbles, or the pleats/mesh are damaged; a washable filter still wears out eventually.
Do I have to buy the genuine iRobot part, or will a compatible one work?
Yes — a compatible (aftermarket) pre-motor filter works well in the iRobot Roomba 694 as long as it's made for this exact model. Look for 4.3+ stars with plenty of reviews, and confirm the listing names your exact model.
What happens if I don't replace the pre-motor filter?
Left too long, a worn pre-motor filter causes: Reduced suction. It can also strain the motor over time, so replacing it on schedule is far cheaper than a repair.
