Ninja Professional Blender BL660: problems, parts and running costs

Checked: 2026-10-19

Summary

A 1100 W countertop blender with a 72 oz plastic pitcher and two 16 oz single-serve cups, on sale since 2012. The running cost is replacement parts rather than consumables: the pitcher is the weak point, SharkNinja sells every part directly, and a motor base swap costs most of a new unit. It is a good buy at or under $130 and a weak one above $150.

Common problems and fixes

Pitcher cracking and leaking — the most common failure: iFixit owners report the plastic pitcher cracking after months of use, often near the base where torque stress concentrates, and several owners are on their third or fourth replacement; some were told the pitcher is not covered under warranty. Fix: SharkNinja sells a 72 oz replacement pitcher with lid, and third-party alternatives exist. [6][1][19][9]
Unstacked blade assembly (2015 recall) — the stacked blade assembly is not locked into the pitcher; a 2015 CPSC recall covered about 1.1 million units sold March 2012 to September 2015 after 53 laceration injuries, and the remedy was revised instructions rather than a repair. Not a warranty matter: remove the blade assembly before pouring or storing the pitcher and inspect the blades before each use. [3][2][12]
Motor base failures — owners report a blinking red light and no power after extended use; repair guides cover the control board varistor and the drive coupling. The 1-year limited warranty covers defects in materials and workmanship but excludes “all blending vessels, lids, cups, blades”. [7][17][21][9]
Single-serve cups not engaging — with a cup mounted the blender sometimes will not turn on; reseating the cup is the first workaround, and the iFixit troubleshooting wiki covers the rest. [18][7]
Leaking from the blade assembly gasket area — reported in troubleshooting threads; third-party blades and gaskets are widely available. [7][19]

Parts and consumables

72 oz Total Crushing pitcher with lid — $72.99 at SharkNinja (October 2026) [1]; the part owners replace most often, with some going through three or four pitchers. [6]
Stacked 6-blade Total Crushing blade assembly — $27.99 at SharkNinja (October 2026) [1]; no replacement interval documented.
Pro Extractor blade for Nutri Ninja cups — $30.99 at SharkNinja (October 2026) [1]; no replacement interval documented.
Nutri Ninja cups (16 oz, two included) — $13.99 each at SharkNinja (October 2026) [1].
Lids — $7.99–$9.99 at SharkNinja (October 2026) [1].
Motor base — $99.99 at SharkNinja (October 2026), roughly 62% of the price of a new unit [1].
Third-party blades and gaskets — widely available outside the SharkNinja parts catalog [19].

Yearly running cost

There are no consumables and no documented electricity figures; the running cost is failure-driven parts. At SharkNinja’s October 2026 parts prices, a cracked pitcher is $72.99, a blade assembly $27.99, a Nutri Ninja blade $30.99, cups $13.99 each and lids $7.99–$9.99, and the motor base is $99.99 [1]. If the pitcher cracks at two years and the motor base fails at four, parts alone approach the original purchase price, so budget for replacements from the start. [1][6]

When it is a good buy

Reported street prices: Lowe’s listed the BL660 at $119.99 in 2026 [4][20]; Best Buy has carried it at $139.99 [16]; SharkNinja’s own page lists $159.99 (October 2026) [1]. At or under $100 the BL660 is a strong buy: 1100 W, 72 oz pitcher, single-serve cups, dishwasher-safe parts and a parts catalog that keeps it alive. From $101–130 it stays reasonable if the single-serve cup system matters; competitors at this price may offer glass pitchers or higher wattage. From $131–150 it is fair value, and above $150 newer Ninja models with Auto-iQ programs are the same money [1][8]. The 1500 W BL770 with food processor is the better choice when you want more power and food processing [20]; the lower-powered 1000 W BL610 is the better choice when you simply want to spend less [20]; a blender with a glass pitcher is the better choice at $131–150 if plastic durability is the concern [11][3].
