Cost to own

Eureka J15 Max Ultra vs eufy Omni E28: 5-year ownership cost

Two hot-wash and auto-empty docks with no paid plan. This page prices the parts each maker sells, counts the failures that need a person, and checks the consumable and warranty terms that carry into year five.

In a dining room a black round robot vacuum sits in its tall dock, whose top hatch is open with the cleaning-solution cartridge lifted out, while a dark square-cornered robot vacuum mops the boards beside it with one pad swung out.

Maker product and support pages

Same on both: no paid plan; both apps list no in-app purchases. Prices are list prices at each maker’s own US store; a part counts only when its maker states both a price and an interval.

In the corner of a dining room a dark square-cornered robot vacuum sits charging in its tall dock, whose front bag door is open; the full dust bag lies on the floor beside a pedal bin and two new bags lie by the sideboard.

  • Omni E28 · eufy.com product and accessory pages; eufy support user guide page; eufy Clean app listing, checked 2 Oct 2026

A part counts toward a year only when its maker states both a price and an interval. A part with either missing is listed and left out of the total, never estimated.

Questions

What readers ask

Does the Eureka J15 Max Ultra need a detergent subscription?

No paid plan was found. The app listing shows no in-app purchases. Eureka sells a cleaning solution in its store, but no page found says the robot requires it.

Does the eufy Omni E28 need its own cleaning solution?

Its product page says the dispenser uses eufy’s cleaning solution, with a cartridge lasting up to 6 months. No page found says another solution is blocked.

Does either robot have a paid plan?

No. Neither the eureka robot app nor the eufy Clean app lists in-app purchases. Paid cloud plans from eufy sit in a separate security-camera app.
