PUDU ET1 vs CC1: compact cleaning or larger tanks?
Start a PUDU ET1 versus CC1 comparison with the building layout. ET1 lists a 500 × 380 × 580 mm body; CC1 lists larger water tanks. Neither characteristic alone establishes which robot delivers more useful work during your shift.
Manufacturer specifications as a starting point
| Parameter | ET1 | CC1 |
|---|---|---|
| Body dimensions | 500 × 380 × 580 mm | Confirm the quoted variant’s dimensions |
| Clean / wastewater tanks | 8 / 7.2 litres | 15 / 15 litres |
| Advertised efficiency | 300–720 m²/h | 700–1000 m²/h |
| Decision evidence | A narrow-route trial and roller maintenance observation | A longer-route trial with the correct equipment |
These figures come from separate official product pages, not a shared RoboMorrow measurement. The m²/h ranges may use different modes and assumptions. Body width is not minimum turning clearance or a guarantee of passing pedestrians in an aisle.
A shop with narrow aisles
Mark the tightest locations under normal stocking conditions: promotional displays, protruding shelf feet and delivery staging areas. Test straight travel, turning, entry into a cross-aisle and the route back to the station. ET1 is a candidate for that trial; acceptance requires repeatable route completion.
A larger open floor
Include CC1 when assessing longer routes, but larger tanks do not automatically double cleaned area. Water use depends on the mode, soiling and repeat work. Measure servicing interruptions across the complete cleaning window and the floor area actually accepted as clean.
Food service and mixed flooring
Select real surfaces and contamination approved for the machine. Do not assume compatibility with every grease, waste type or chemical. Check residual moisture, manual corrections at walls and cleaning the robot after the shift. Confirm modes and carpet accessories for the configuration quoted.
Five results needed for a decision
- Accepted area within the available time, without counting the same section twice.
- Number and combined duration of human interventions.
- Robot cleaning and water-service time after the task.
- Locations still requiring manual cleaning.
- A complete quote covering station, installation, accessories, training, service and recurring charges.
A conditional decision
If geometry is the constraint, first test ET1 in the hardest aisle. If frequent water servicing limits the route, compare CC1 against the same required cleanliness. If both pass, move to total cost and local service availability.
We do not have two comparable current quotes for your country and building, so we do not give an invented starting price or payback period. A quote request should specify the actual cleanable area, floor types, available task window and route plan. Give both suppliers the same brief.
