Start with real floor area
Measure usable square metres, not the building's total area. The robot is sized by routes and frequency, not by the property's commercial size.

KLEENBOT C30, C40 and C55 comparison to choose your cleaning robot
This guide helps you decide which KEENON autonomous cleaning robot fits best based on floor area, cleaning frequency, tank size and ROI target. The right choice avoids over-investing and lets you start with the model that pays back soonest.
| Model | Recommended use | Main advantage | Recommended first step |
|---|---|---|---|
| KLEENBOT C30 | Compact areas, restaurants, offices and small hotels | Lower upfront investment; dry cleaning (3-in-1) | Request a floor-area assessment |
| KLEENBOT C40 | Mid-size hotels, hospitals, care homes and common areas | Best balance of coverage, scrubbing and operating cost | Calculate the C40 ROI |
| KLEENBOT C55 | Airports, shopping centres, logistics and large facilities | High scrubbing capacity for intensive operations | Assess a zone-based pilot |
| Parameter | C30 | C40 | C55 |
|---|---|---|---|
| Published performance | Up to 600 m²/h | Up to 1,100 m²/h | Up to 2,376 m²/h (maximum theoretical efficiency) |
| Functions | Sweeping, vacuuming and dry mopping (3-in-1) | Sweeping, vacuuming, scrubbing and dust mopping (4-in-1) | Sweeping, scrubbing and mopping (triple roller) |
| Clean water tank | Not applicable (dry cleaning) | 16 L | 60 L |
| Waste water tank | Not applicable (dry cleaning) | 11 L | 47 L |
| Recommended floor area | Up to 500 m² | 500–4,500 m² | Over 3,000 m² |
| Battery life | Up to 6 h (vacuuming/sweeping) · up to 10 h (mopping) | 5 h (scrubbing) · 12 h (sweeping) | 5 h (hot-swappable battery) |
| Cleaning width | 61 cm (with side brushes) | Sweeping 56 cm · scrubbing 40 cm | Scrubbing 55 cm (without side brush) |
| Weight with battery | 35 kg | 70 kg | 150 kg |
Values taken from each model's product page (linked in the header). Hourly performance is the figure published by the manufacturer and is not the same as the recommended floor area; the C55 figure is a maximum theoretical efficiency. The C30 cleans dry and has no water tanks.
All three models are available to buy outright, through financing or as a monthly-fee service (OpExFlow), with ownership, maintenance and continuity conditions depending on the contracted option. Deployment time is planned during the assessment according to the property and its integrations.
How to choose the right one
Weigh shifts and noise
If cleaning happens at night, noise level, battery life and return-to-dock matter as much as raw power.

The base price is only one part. Include installation, mapping, training, support, accessories and consumables.

Which model is the most balanced for hotels?
In most mid-size hotels, the KLEENBOT C40 is the sweet spot for coverage, tank and operating cost.
When should I choose the C55?
When the floor area per shift clearly exceeds 2,000 m² or there is heavy traffic and a need for high capacity.
Is the C30 good enough for hotels?
Yes, in small hotels, specific zones or compact spaces where a larger robot isn't worth installing.
How much does each model cost?
As a guide, the KLEENBOT C30 starts at €8,900, the C40 at €12,500 and the C55 at €18,900 (+ VAT). They are also available through financial renting (with Grenke) or as an OpExFlow service (RaaS) with a monthly fee. The final price is on request depending on configuration and included services.
