Trifo Lucy Ultra

Name: Trifo Lucy Ultra
Brand: Trifo

Object recognition lifts navigation beyond prior Lucy versions, but the core autonomy posture (map-guided, obstacle-avoidant cleaning) stays conditional. You gain semantic framing for obstacles; the coverage pattern and operational scope remain Level III standard.

Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyHandles new obstacles and re-plans in real time; rare in consumer products.
To reach Level IVSustained operation across sessions, including layouts and conditions it has not met before.
IIIConditional AutonomyThis robot

Trifo Lucy Ultra finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control
Laser mapping with Time-of-Flight obstacle sensors; onboard 1080p camera with night vision for monitoring and recording
Why this level
- Independent testing documents laser mapping paired with Time-of-Flight obstacle sensing, sufficient for unattended runs across a mapped floor.
- Operates without teleoperator fallback within known floor plans.
- Does not generalize to novel environments or multi-home mapping handoff without manual intervention.

Our assessment did not establish an independent source for task completion on this machine, so that input is left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where it reaches 30% of the rubric we publish no number at all.

Capability40% of the score55What it does without you.

Task completionnot countedno source verified40

Evidence

It carries mopping hardware, so mopping is part of its job, and nothing here is self-serviced. There is no auto-empty base at all, and the 252 ml dustbin is small, emptied and rinsed by hand after most runs. The 366 ml water tank is refilled for each mopping pass and the record states it sets how much floor one pass covers. No automatic mop lift is documented, so the water tray comes off before running on carpet. Single-floor mapping only, and it cannot change levels.

Coverage and navigation10% of the score58

Evidence

Make Tech Easier's hands-on review reports it took over 10 minutes to map a medium sized living room and that it would not carry on into the attached kitchen through an open doorway, so the reviewer had to move the vacuum into the kitchen manually via the app before it would map there; the maps it does build are saved and used for scheduling and zones.

Edge-case recovery10% of the score50

Evidence

Independent testing describes laser mapping paired with Time-of-Flight obstacle sensors as sufficient for unattended runs, so there is genuine pre-contact perception and the category trap's hard ceiling does not apply. Cliff detection halts at stairs. The record documents no recovery behavior at all, and the 1080p camera is a monitoring stream rather than a recovery mechanism, though it does give the owner a way to see why the robot stopped.

Operating envelope4% of the score60

Evidence

4,000 Pa on hard floors and low pile, with owner reports documenting suction loss and inadequate agitation on plush flooring, and no automatic mop lift documented so carpet means removing the water tray first. Single-floor mapping, and the 366 ml tank bounds a mopping pass. One genuine widening: dual-band Wi-Fi, so it is the only machine across these 31 records that works on a 5 GHz-only network.

Dependability40% of the score58Whether it keeps doing it.

Field failure rate16% of the score48

Evidence

Four and a half years since 2022, past every cap, and the evidence is independent in kind but very thin: two hands-on reviews from small outlets, Make Tech Easier and Mighty Gadget, both linked, plus Trifo's own product page. There is no owner_reports source of any kind, no failure_modes section and no reliability_over_time section. Trifo is a small vendor with a limited coverage footprint, so a silent record here reflects the absence of anyone assembling one rather than an established clean sheet.

Software stability14% of the score82

Evidence

Below the ordinary silent-record anchor. There is no firmware_notes source in the record at all and no changelog is cited anywhere, so nothing establishes that updates ship, only that the robot has Wi-Fi and an app. The record also notes Trifo publishes no data retention or access policy that could be located, which speaks to the vendor's general opacity. It stops short of the 25 anchor because that state requires opacity plus owners reporting problems, and no owner reports exist here in either direction.

Support longevity10% of the score40

Evidence

Scored as commitments and there are few to read. One linked Trifo product page, no published warranty term, no repair channel, no parts catalog beyond named costs for a filter at $12 to $18 and a side brush at $15 to $20, and no data or software policy the record could locate. Trifo is a small vendor and the machine is four and a half years old, so the concern about a parts channel narrowing applies directly, with no third-party aftermarket to fall back on.

Ownership burden20% of the score46What it asks of you.

Routine maintenance12% of the score36

Evidence

A heavy routine for a vacuum. After most runs: empty and rinse the 252 ml dustbin, rinse the mop pad, and empty the 366 ml tank. Weekly: tap the filter clean and wipe the camera lens. Every three to six months the primary filter; quarterly the side brush; seasonally the dock contacts. There is no dock automation of any kind and the smallest bin here, so the after-run task arrives more often than the record's own cadence suggests.

Consumables8% of the score61

Evidence

A filter at $12 to $18 every three to six months and a side brush at $15 to $20 quarterly, plus mop pads, coming to roughly $110 a year against a $360 to $400 machine, about 28 percent of purchase price annually. There is no bag because there is no base. The quarterly side brush is a short cadence, and every part runs through one small vendor with no third-party aftermarket, so the cost is less of a concern than the sourcing.

middle half of the databaseits medianthis robot

Reported, not scoredneither measures how well the robot works

Five-year cost$950

Cheap to buy, proportionally expensive to run. About $400 at US retail plus roughly $110 a year in filters, side brushes and mop pads, so consumables exceed the purchase price within four years. No subscription for core operation, including the live camera stream. Parts come from a single small vendor with no third-party aftermarket, which is a sourcing risk rather than a price one.

Common questions

What people actually ask.

7 answered

OperationDoes the Lucy Ultra mop?

Yes. Trifo lists it as a vacuum and mop, with a 2-in-1 tray holding a 252 ml dustbin and a 366 ml water tank. A microfiber pad is dragged behind the robot while it vacuums. Independent testing reported no streaking. No automatic mop lift is documented for this model.

OperationWhat does the Lucy Ultra's camera do, and where does the video go?

The robot carries a 1080p camera with night vision and motion detection, and streams live video for home and pet monitoring through the Trifo app. Review testing found no cloud storage of stills or video. Trifo publishes no data retention or access policy we could locate.

OperationHow does the Lucy Ultra navigate?

Independent testing of the Ultra describes laser mapping paired with Time-of-Flight sensors for obstacle handling. Trifo brands its vision work TIRVS, the Trifo Intelligent Robotics Vision System, but no public source ties a specific version of it to this model.

OperationDoes the Lucy Ultra use disposable dust bags?

No. There is no auto-empty base and no bag. The robot carries a 2-in-1 tray holding a 252 ml dustbin and a 366 ml water tank, and the bin is emptied and rinsed by hand. Recurring consumables are the filter and the brushes.

CompatibilityDoes the Lucy Ultra work with 5 GHz WiFi?

Yes. Supports dual-band WiFi (2.4 GHz and 5 GHz). Networks with only 5 GHz or only 2.4 GHz both work; performance is stable on either band per owner reports.

OperationCan the Lucy Ultra map multiple homes or floors?

Single-floor mapping only. Multi-floor homes require manual dock relocation and a new map, then reset. Does not support saved multi-home profiles; mapping is floor-specific.

OperationWhat happens if the Lucy Ultra encounters stairs?

Cliff-detection halts at stairs; the robot will not descend. On multi-level homes, position the dock on the primary cleaning floor and manually dock on other floors.
