Attachment A-Statement of Work - UV Robotic Scrubber (002).pdf

STATEMENT OF WORK

Description of Use – A self-propelled machine that gets into those nooks and crannies you might otherwise miss and will get it done it every single time. Need technology that will allow the user to map out a route that delivers between 98% and 99.5% coverage. The user needs to be able to do it with no help from anyone else. Machine needs to be able to clean an area once and precisely retrace the same path again, and again, and again.

Technical Specifications –

GENERAL

Machine shall be an autonomous 20-inch three-wheel battery-powered stand-on automatic scrubber with the ability to scrub and vacuum in one pass

CLEANING

MODES

Machine shall be operational in both autonomous and manual cleaning modes.

AUTONOMOUS

PLAN CREATION

Machine shall offer two modes of autonomous cleaning:

• Copycat mode shall replicate exactly what the operator does in a single manual ride and play it back each time thereafter.

• Machine shall replicate when/where the operator adjusts down pressure, vacuum power, solution flow and water.

• Fill-In mode shall allow the operator to drive the perimeter of a room once and automatically calculate the most efficient route to scrub each inch of the area and avoid obstacles along the way each time thereafter

SAFETY

Machine shall be certified to meet the CSA (Canadian Standards Association) and ANSI (American National Standards Institute autonomous safety standards:

• CSA/ANSI C22.2#336.2018 Ed.1

• UL 60335-1:2016 ED.6

• UL 60335-2-72:2017 Ed.1

• CSA C22.2#260335-1:2016 Ed.2

• CSA C22.2#60335-2-72:2017 Ed.1

Machine shall have a separate safety system independent of the mapping, obstacle system, and path planning. It shall override autonomous system and can stop immediately if an unsafe event is detected. Shall have drop-off sensors to detect drop-offs like a loading dock, stairs, escalators, etc.

Machine shall notify people around the machine of direction with turn signals.

AUTONOMOUS

RUN TIME

Machine shall operate up to 5-6 hours autonomously on a single charge (floor type dependent) and up to 2.5 hours of uninterrupted cleaning between dump and refill.

OPERATOR

ALERTS

Machine shall alert the operator as soon as it needs assistance or is ready for another task. Operator will receive an SMS message directly to their cell phone with all the details. Operator shall be able to subscribe and unsubscribe to this service as they choose with a simple text message.

WIRELESS FIDELITY AND MACHINE

COMMUNICATION

Machine shall communicate via Wi-Fi/4G/etc. with devices and other machines for maintenance, troubleshooting and data transmission for other purposes.

DARK/BRIGHT

OPERATION

Machine shall operate autonomously with or without the lights on with no compromise to safety using infrared sensors and cameras to sense and detect position and obstacles. This allows for a reduction in facility costs by operating with less lights and HVAC systems running.

Machine shall also be unaffected by harsh bright lights while operating autonomously.

MAXIMUM AUTONOMOUS SPEED

Machine shall operate autonomously at a speed of 2.35mph

OBSTACLE

DETECTION

Machine shall sense an obstacle up to 80 feet ahead on the cleaning path and automatically create a safe path around without stopping When an obstacle is suddenly added to the cleaning path, the machine shall stop and determine a safe route around the obstacle.

DIGITAL

SERVICES

Customer shall have full access to reports, updated daily, that tracks and details autonomous/manual run time, time of the day operation, and error messages.

Customer shall have access to a system which records operational data of your fleet and ensures transparency. The system data includes machine working time, the machine down time, time of day that each activity occurred, the geographic location of the machine 24/7, Machine ID, and as an option can include information about the operator through the system

Customer shall have access to an app to provide the site manager with real-time machine usage data and send notifications if there are deviations in start time or performance.

GRADEABILITY

Shall be minimum of 8.2 degrees for transport mode, 4.5 degrees in manual cleaning mode and 2.8 degrees in autonomous cleaning mode.

SOFTWARE

UPDATES

Software updates shall be provided free of charge and installed on the machine as soon as possible through the machines interface.

IT SECURITY

Machine shall have secure communication ensure by IT encryption standards to prohibit any unauthorized party to access machine data or machine directly. No physical driving possible through remote machine access or maleficent self-driving software updates.

SMART KEY

SYSTEM

Machine shall use a two-key system to enable supervisors to configure the machine to best fit their facility. Lock out certain features like double down pressure, higher flow rates to reduce damage and operating cost. Assign keys to individual users to see who has been operating the machines.

• Supervisor Key: Allows for creating new autonomous cleaning plans and deleting old ones. Can also configure the machine to exact parameters for the most efficient clean.

• Operator Key: Can only play back an autonomous cleaning path, can’t create new ones or delete old ones.

CLEANING

PATHS

The machine shall be available in the following configurations:

• 20-inch disc, onboard detergent dispensing system, onboard battery charger with a removable pad holder

SOUND LEVEL

Sound pressure level shall not exceed 63 dB A when measured in accordance with IEC 60704-1/ISO11201 for operator safety comfort and daytime cleaning of occupied spaces. The machine shall also have a quiet mode that further reduces the sound level to 60 dB A in noise sensitive environments.

DETERGENT

CONSERVATION

SYSTEM

Machine shall have as standard an onboard detergent dispensing system (onboard detergent dispensing system) utilizing a 1.3 gallon refillable cartridge that allows the use of any manufacturers’ detergent operates at all available flow rates, and allows the quick interchange of multiple detergent cartridges for varied cleaning applications.

The system must be able to clean in four distinct modes to minimize costs, reduce labor, and ensure environmental sustainability.

• Chemical-free cleaning (zero detergent)

• Ultra-low detergent strength (weak detergent)

• Ful Detergent strength (strong detergent)

• Burst of Power (60 second increase in detergent strength, brush pressure and solution flow)

The onboard detergent system shall be capable of accurately diluting detergents at the following ratios at any flow rate.

• 400:1,1/4 oz./gal, 0.25%

• 300:1,-oz./gal,0.3%

• 256:1,1/2oz./gal, 0.4%

• 200:1,-oz/gal,0.5%

• 150:1,-oz/gal,0.66%

• 128:1,1 oz./gal,0.8%

• 100:1,-oz./gal,1%

• 64:1,2 oz./gal,1.5

• 50:1,1.5 oz./gal,2%

• 32:1.4oz./gal, 3%

WATER

CONSERVATION

SYSTEM

Disc and REV machines shall come standard with a calibrated low solution flow rate setting that consistently and repeatably sets a low solution flow rate to increase the per tank run time or productivity per tank full thereby lowing detergent costs, labor cost and reducing environmental impact.

Disc machines.

• Low flow rates: 0.16 GPM

• Medium flow rate: 0.35 GPM

• High flow rate: 0.50 GPM REV machines:

• Low flow rate: 0.11 GPM

• Medium flow rate: 0.16 GPM

• High flow rate: 0.23 GPM

SOLUTION TANK

The machine shall have a rotomolded solution tank with minimum capacity of 15 gallons to provide the required level of productivity. The tank shall have both a front and rear fill port to increase productivity when filling. The solution tank output shall be filtered by an externally mounted filter that can be cleaned without reaching into a full solution tank with chemicals or dumping fresh chemicals into the wastewater stream.

SQUEEGEE

The squeegee shall have tool free front and rear blade replacement with no loose fasteners than can become lost, requiring replacement.

The rear blade shall be held on with a simple stainless-steel strap and clamp that releases the blade, so it can be changed quickly and easily while working to ensure a safe and dry floor. The squeegee shall have as standard, premium abrasion and petroleum resistant polyurethane blades for long life and lower operating costs. The squeegee system shall have an integrated kickstand that elevates the rear squeegee system shall have an integrated kickstand that elevates the rear squeegee for double scrubbing applications.

BATTERY

Machine shall be equipped with AGM maintenance free batteries for power.
