How to choose
Robot vacuums work harder than you think — running daily cleaning cycles means filters accumulate debris 5-10x faster than a manual vacuum used weekly. Replace filters every 2-3 months (monthly for pet households), side brushes every 3-6 months, and the main roller every 6-12 months. Buying multi-packs of compatible replacements brings the per-unit cost down to a level where you can maintain the manufacturer-recommended schedule without hesitation.
