Reviews for the Kirby Ultimate G Series vacuums are generally good, but there are some negative reviews. New models are sold door to door, with appointment scheduling through Kirby's authorized distributors. Refurbished models are available for online purchase.
A couple reviewers purchased refurbished units and thought the vacuums looked to be used rather than refurbished. These were purchases of factory refurbished vacuums with 5-year warranties. A couple of these reviews noted that the vacuums were missing parts but performed well. Other positive reviews said the vacuum is of very high quality. A common note is the high power of this vacuum.
