Five-year cost of ownership

What each robot actually costs to own

Purchase price plus documented consumables, subscription gating, and replacement events. Bars share one dollar scale, so length is directly comparable. Costs are typical, drawn from manufacturer maintenance guides and owner reports.

Documented failure events

When things break, and what they cost

Field-reported failures placed on the ownership timeline, with associated repair or replacement costs. Sourced from owner forums and manufacturer service documentation.

Month 1 · iRobot Roomba Plus 505 ComboMinor

Mop pad runs too wet on early passes

$0 (adjustable in app)

Reddit owner CantusAvem reports the mop ran too wet at first and worried about wood-floor damage. iRobot's app allows moisture adjustment, but the record documents no factory default that prevents the early over-wetting.

Reddit owner report (CantusAvem) · 2026
Month 2 · MOVA P50 Pro UltraMinor

Shag rug fibers catch the side brush

$0 (avoid shag; no repair)

robot-review.com found some hair may remain ingrained on high-pile rugs and warns shag rugs with long fibers can trigger cliff sensors or catch in the side brush, a recoverable jam rather than damage.

robot-review.com review · 2026
Month 3 · Roborock Qrevo Edge S5AMinor

Brush tangling and navigation quirks reported

$0 (owner-cleared, no parts)

Owner threads on r/RobotVacuums document brush tangling and navigation quirks surfacing within three months of deployment, alongside bag-swap interval feedback. No hardware failure or recall is recorded against the unit.

Month 4 · Ecovacs Deebot T50 Max Pro OmniMajor

Zone cleaning failed on two separate units

$0 (factory reset, no replacement)

TechRadar's tester saw custom zone cleans fail repeatedly on two separate units. One needed a full factory reset and re-pairing, which then failed again the next day. Neither unit was replaced.

Consumables breakdown

Annual cost by part type

Read from each robot’s own record, not restated here. A part is priced only from the manufacturer’s published price for a part its own page lists for that machine, and costed only where a replacement interval has been established. Anything else is left unpriced rather than estimated.

Common questions

What readers ask about this comparison.

Q.
Which of these four asks the least of the owner day to day?
Roborock’s own maintenance record for the Qrevo Edge S5A describes the routine as close to nothing between refills of the station’s own water tanks, and it is the only one of the four with a dated software and security support policy on file. MOVA’s automatic mop-pad removal and reattachment is the other standout, removing a chore even full omni stations usually leave to the owner.
Q.
Do all four publish clear prices for bags, pads and filters?
No. iRobot’s record for the Roomba Plus 505 Combo prices pads, bags, filter and brushes individually, but Roborock’s own documentation states it publishes no bag price and no fixed interval or price for pads, filter or brushes on the Qrevo Edge S5A.
Q.
Does any of the four require a subscription to unlock features?
No. Each product’s own cost record states no subscription applies to the iRobot Roomba Plus 505 Combo, MOVA P50 Pro Ultra, Roborock Qrevo Edge S5A or Ecovacs Deebot T50 Max Pro Omni.
Q.
How solid is the reliability evidence behind these four robots?
Uneven. The MOVA P50 Pro Ultra’s failure-rate assessment sits at the evidence floor because its three cited sources are MOVA’s own documentation, Dreame’s support portal and Robovations’ own tracker log, with no independent source at all. The Roborock and Ecovacs records instead cite VacuumWars, TechRadar and owner threads on Reddit.
Q.
Do any of these robots sell for less than their listed price?
Yes. Roborock’s own price note for the Qrevo Edge S5A spans a $599.99 promotion to a $999.99 list price on the same machine, and MOVA’s record for the P50 Pro Ultra lists $549 to $999. The iRobot and Ecovacs records show no such spread.
