Weeks to months rather than years — and on robots and steam cleaners the annual cost is a meaningful fraction of the machine.
Robot side brushes bend and roller brushes tangle within months; filters, mop pads and dock dust bags run on their own schedules. Steam cleaner descaling cartridges have a stated life that depends on water hardness. Floor washer rollers mat and stop absorbing.
The way to avoid an unpleasant surprise is to search the exact model number plus “filter”, “bag” or “pad” on the same store before buying the machine — and to check the parts exist for that model rather than for the brand.
A discontinued platform is an expensive ornament.
