Capacities vary widely across listings. Examples include: 0.94 gallon; 1 liter; 1 gallon; 1.19 gallon; 2 liter; and 2.5 liter. Expect models anywhere within this range depending on the model.

The listings show several filter approaches: HEPA filtration (including H12 and sealed HEPA), standard filters, foam filters, and washable filters on some bagless models.

Listings commonly specify multi-surface cleaning and explicitly recommend use on hard floors and carpets.

Some models use replaceable bags or sealed multi-layer HEPA bags, while others use a bagless dirt cup with washable filters. Both approaches appear across the results.

Warranty periods in the listings include 1‑year limited, 2‑year limited, 5‑year limited, and lifetime limited warranties, depending on the model.

Many listings highlight pet-focused features such as specialized pet heads/brushes and tangle-free brush rolls, plus HEPA or sealed HEPA filtration systems to help capture dander and allergens.

Several models include cord-management features such as automatic cord rewind or retractable cords for easier storage.
