Solar panel cleaning robots are one of the last robot categories where nobody publishes a price. SolarCleano, the Luxembourg manufacturer that dominates the English-language search results, lists seven machines on its own products page — F1, M1, L1, T1, B1, B1A and E1 — and quotes a price for none of them. Search results fill the vacuum with Chinese factory listings and market-forecast pages.
There is, however, one US dealer that puts SolarCleano behind a working shopping cart. WindowCleaner.com, a US window-cleaning supply retailer, lists three of the seven models with add-to-cart pricing. We read those pages on 8 August 2026 and confirmed the currency through the store's own cart endpoint (USD).
SolarCleano prices at a US dealer, August 2026
| Model | What it is | US dealer price | In stock |
|---|---|---|---|
| SolarCleano M1 | "Mini" remote-controlled cleaner, 0.8 m brush, 49 kg, ~3 h battery | **$31,628.24** | Yes |
| SolarCleano T1 | Robot *transporter* — carries F1/M1/L1 between panel rows | **$41,129.41** | No |
| SolarCleano F1 | Full-size cleaner, 1.2 m helicoidal brushes, ~2 h battery | **$42,702.35** | Yes |
| World Solar Robotic Panel Cleaner | Entry remote-controlled cleaner, 3–4 h lithium, needs an external pure-water feed | **$5,099.99** | No |
| World Solar Dual Power Solar Brush | Powered brush on a 12.5 ft telescopic pole (not a robot) | **$1,695.00** | No |
Four of the seven SolarCleano models — L1, B1, B1A and E1 — have no published US price at all. That is the first thing to plan around: roughly 43% of this manufacturer's line is buyable at a visible number, and the rest is a quotation process.
The most expensive thing in the catalogue cleans nothing
The T1 is not a cleaning robot. It is a tracked platform that lifts an F1 or M1 from one panel row to the next, tilts up to 34°, raises its deck from 0.8 m to 2.4 m, and carries up to 2,000 kg. It costs $41,129.41 — 130.0% of the M1 it exists to carry, and 96.3% of the F1.
That is the budgeting trap in this category. The dealer's own copy explains why anyone pays it: with a transporter, "you can now clean up to 4 MW per day with one single operator." The robot is the cheap half of a one-operator crew; the logistics of getting it onto the next row is the expensive half. Anyone pricing a utility-scale cleaning operation on the robot alone will be out by roughly 100%.
Price per megawatt-day, not price per robot
SolarCleano's own marketing gives a throughput figure for each machine: the M1 covers roughly 1 MW per day with one operator, the F1 roughly 2 MW. On that basis:
- M1 — $31,628.24 per MW-per-day of capacity
- F1 — $21,351 per MW-per-day of capacity
The F1 costs 35.0% more and buys about twice the daily coverage, so the more expensive machine is the cheaper one per unit of work. The M1's case is portability, not economics: it breaks into three parts each under 26 lb, which is what makes it usable on rooftops and glass roofs where an F1 cannot be carried.
The bottom of the market is a different product
Chinese manufacturers do publish numbers. Todos, one of the factories that ranks for this search, advertises promotional prices of under $1,300 for its G3, under $2,500 for its G4 and $2,600 for a remote-controlled G2. Treat those as a different line item, for two reasons we have hit before in this category of research: they are factory prices with no stated basis (almost certainly ex-works China, before freight, duty and any US support), and the G3/G4 are waterless automatic units rather than the water-fed field robots above. Our own August 2025 agricultural-drone work found landed US package prices running 2.5–4× the Chinese FOB figure for the same brand, so a $1,300 factory price is not a $1,300 delivered robot.
The honest ladder as of August 2026 therefore looks like this: $1,695 buys a powered pole brush; about $5,100 buys an entry remote-controlled cleaner; $31,600–$42,700 buys a professional SolarCleano; and the transporter that makes a professional machine efficient adds another $41,100.
What to check before you buy
- Ask whether the quote includes the transporter. On this dealer's shelf it nearly doubles the bill.
- Ask for throughput in MW/day or m²/h, not brush length. It is the only number that converts price into cost per wash.
- Confirm the water source. The World Solar unit and the SolarCleano machines connect to a standard 0.5–0.6 in garden hose; the pure-water system is not in these prices.
- Check stock, not just price. Two of the five machines above were listed and unbuyable on the day we read them.
