Built to perform. Priced to sell.
Quite simply, these hot tubs offer the same water filtration system as any competitive product and are priced better. These are "why pay more hot tubs", or for someone who simply did not intend on getting into a self-cleaning hot tub price point.
These hot tubs are made to the same quality standards, on the same production line with the same hands and the same tools as the SELF-CLEANING LINE of hot tubs, but they offer a more traditional line of options and filtration. These hot tubs are generally priced well because they are lighter on options and features, but they still offer the same components, structures, insulation etc as their SELF-CLEANING cousins.
