Common replacement parts include brush rolls and bottom plates, clean and dirty water tanks, mop pads and refills, HEPA filters, and accessory kits that bundle brush roll and bottom plate replacements.
Replacement listings describe a clean water tank (holds water and cleaning solution) and a dirty/collection tank (captures extracted water and debris). Both typically include gaskets and valves for a tight seal and are made from clear, BPA-free plastic so you can monitor fluid levels.
Listings advise that brush rolls are easy to clean and replace and commonly recommend replacing them about every 6 months. Some listings note machine features—like self-cleaning systems or rinse/storage trays—to help rinse and dry brush rolls after use.
HEPA filter listings typically report packaged dimensions around 9.25" x 2.75" x 0.5", list compatibility with multiple upright and lift-off style models, and are offered in multi-packs such as 2‑count and 4‑count options. Verify compatibility on the product page for your model.
