SH1 -- Support Manual

Professional miniature upright scrubber-dryer for small and medium-sized indoor environments, combining washing, brushing, and vacuum drying in a single pass.

Page 1: Overview

What is the SH1?

The SH1 is a professional miniature upright scrub-and-dry cleaning machine designed for small and medium-sized indoor environments with complex layouts. Unlike the autonomous CC1 robots, the SH1 is a manually operated push-behind unit -- an operator walks behind the machine and steers it across the floor.

The SH1 combines washing, brushing, and vacuum drying in a single pass using high-speed, high-pressure disc brushes. It is compact enough to navigate tight spaces, corridors, and areas around furniture that larger autonomous robots cannot reach. With a productivity rating of 1,100 to 1,600 sq m/h, the SH1 handles significant floor area on a single battery charge.

The machine supports Wi-Fi connectivity and the PUDULink app for smart monitoring features including real-time task reports, staff management, device tracking, lease management, and anti-theft protection. It can be used on both indoor and outdoor flat surfaces, making it more versatile than the indoor-only CC1 range.

What to check: 1. Check that the squeegee is lowered and flush against the floor. 2. Inspect rubber strips for wear, cracks, or deformation. 3. Verify the cleaning mode matches the soiling level (use Heavy Duty for stubborn stains). 4. Check disc brush bristle condition. 5. Confirm the solution tank has water and cleaner.

Solution: Flip or replace worn squeegee rubber strips. Replace worn disc brushes. Use a stronger mode for heavy soiling. Ensure adequate cleaning solution. For edge cleaning, press the squeegee closely against the wall.

Escalate if: Streaks persist after replacing squeegee strips and brushes.

Squeegee leaves water trail along walls or edges

What you see: Water marks or dirty residue along walls and edges after cleaning.

Likely causes: Squeegee not pressed close to wall during edge cleaning; rubber strips worn unevenly; machine not angled correctly.

What to check: 1. During edge cleaning, push the machine so the squeegee closely follows the wall. 2. Inspect squeegee rubber strips for uneven wear. 3. Check that the machine is in the correct working position angle.

Solution: Angle the machine so the squeegee presses tightly against the wall during edge passes. Flip or replace unevenly worn rubber strips. Practice consistent edge-following technique.

Escalate if: Usually a technique issue. Escalate only if rubber strips are defective.

Battery drains faster than expected

What you see: Runtime noticeably shorter than rated 70 minutes (Normal) or 100 minutes (ECO).

Likely causes: Battery not fully charged; consistently using Heavy Duty mode; battery degraded from age or misuse; battery not maintained during storage.

What to check: 1. Charge fully (all four indicators solid white) before testing. 2. Note which cleaning mode is used; Heavy Duty drains fastest. 3. Check battery age and storage history. 4. Verify the charger is providing full power.

Solution: Always fully charge before each session. Use ECO mode when possible. If stored without periodic charging, perform several full charge/discharge cycles. Replace the battery if significantly degraded.

Escalate if: A fully charged new battery provides significantly less than 70 minutes in Normal mode.

Machine tips over or feels unstable

What you see: Machine falls or tilts unexpectedly during use or storage.
