When people look at AI companion hardware, most eyes go straight to the sticker price. But the business model of these products is usually front hardware to pull you in, back subscription to keep you. The robot you bring home often hides the real bill in the monthly fee. Before ordering, separate three numbers: device price, recurring fee, and shutdown risk, so you never end up with a companion that goes silent halfway through.
Three numbers: device price, monthly fee, shutdown risk

The device price alone spans a huge range. Desktop pets like Eilik are a one-time 139.99 dollars and Moflin runs about 59,400 yen in Japan, both essentially buy-once with no subscription. LOVOT in Japan costs 385,000 to 485,100 yen for the body, then about 11,000 yen a month in service, pushing five-year total cost of ownership past one million yen. ElliQ is the sharper example: a 249 dollar activation fee plus 59.99 dollars a month, deployed at scale through state programs. The monthly fee is where makers make their money, LOVOT period three-year subscription already approaches the hardware price itself. The dangerous third number is shutdown risk. Companion hardware leans on the maker cloud, so if the company closes, the product can brick overnight. Moxie is the cautionary tale: original maker Embodied wound down in late 2024, took its servers offline on January 30 2025, and silenced thousands of sold units until Moxie Robots reopened orders at 499 dollars on February 1 2026. Anki Vector nearly went dark after bankruptcy in 2019.
How to pick without stepping on the trap
First, check whether core features depend on the cloud or a monthly fee. Devices that run offline, like Eilik and Moflin, survive a maker shutdown best. Second, calculate three-year total cost of ownership instead of staring at the sticker, a 249 dollar activation plus monthly plan can cost multiples of the headline number over three years. Third, look at whether the maker is public, and whether it has a record of steady operation and firmware updates, smaller teams carry higher shutdown odds. Fourth, make sure the subscription can be cancelled anytime and the hardware is not held hostage, designs that lock core functions behind renewal deserve a second thought before you buy. For older adults, ElliQ ships at scale with strong proactive care but a steep monthly bill. For kids, Eilik is cheaper, tougher, and safer offline.
The value of a companion product lives in the relationship. But that relationship is also tied to a bill. Treat the monthly fee as relationship renewal, run the three numbers before buying, and what you get is a partner that stays present, not a statue that may fall silent.
