Reading by environment

Floor area band36 L of water and a 3 h runtime: medium-sized floor areas. The 11 h charge is the structural constraint: it forces overnight recharging and sets the frame for operations.
Footprint / aisles800 mm passage width, 138 kg: compact, at ease in hospital, care home and school corridors.
Floors and soiling2-in-1 hybrid for hard floors. No carpet. Large debris must be pre-swept.
Occupancy / hoursAimed at healthcare and sensitive facilities. Data hosted in Switzerland: a concrete sovereignty and confidentiality argument for hospitals and care homes.
PlumbingNo dock: the 36 L tanks are filled by hand.
LongevityAsset: battery guaranteed for 5 years, rare in the sector, which secures the most expensive item to replace.

Floors and soiling

Compact hybrid scrubber-dryer for hard floors: stuck-on and wet soiling in the corridors of hospitals, care homes, schools and museums. No carpet. Large debris must be pre-swept. Its healthcare positioning and data confidentiality make it a coherent choice for sensitive facilities.

What the manufacturer does not say

Data hosting in Switzerland is a genuine argument. In hospitals and care homes, data sovereignty and confidentiality carry weight: this is a concrete differentiator that few competitors offer.

The 5-year battery warranty secures the cost. It is the most expensive item to replace on these machines: a long warranty is reassuring and rare.

The 11 h charge calls for organisation. This is the real limit: overnight recharging is mandatory, with no quick top-up during the day. Cost structure: machine plus consumables, battery covered for 5 years.

Purchase or outsourced service

On a purchase (capex), data hosting in Switzerland and the 5-year battery warranty secure the sensitive items (sovereignty, replacement), but the 11 h charge imposes strict scheduling of cleaning slots. Under an outsourced service (opex), the contractor absorbs this recharging constraint and guarantees continuity. See the Pudu range and the on-site demonstration, or our robotic cleaning service.
