Design and making of manual floor cleaning machine
CHAPTER 1
                                     1. INTRODUCTION
    1.1 introduction
Effective cleaning and sanitizing helps and protect the health of the human beings directly and
indirectly. Also, cleaning and sanitizing prevents the pest infestations by reducing residues that
can attract and support bees, pests etc. It also improves the self life of the floor, walls etc due to
regular cleaning and maintenance. In recent years, most of the people prefer to use trains or
buses for commuting and hence these places are littered with biscuits covers, cold drink bottles
etc. Hence, it is necessary to clean the bus stands and railways stations at regular interval.
There is no one single cleaning method that is suitable cleaning technique and also the
equipment should be user friendly. Cleaning work can be physically demanding and a need has
been identified to developed methods for systematic ergonomics evaluation robots are getting
more popular for busy and aging populations due to lack of workers. However in India,
unemployment is more and hence there is a need to develop less labour oriented cleaning
machine. Hence, the present work is aimed to design , development and evaluation of a manually
operated floor cleaning machine. In recent years, conventional floor cleaning machines are most
widely used in airports , railway stations, malls, hospitals and in many commercial places, as
cleaning is one of the important parameter for the sanitation and government regulations . For
maintaining such places, cleaning the floor is the major taskwhich is necessary.
There are conventional floor cleaning machines available to perform floor cleaning operations in
above said places. Generally a conventional floor cleaning machines requires electrical energy
for its operation. In India, especially in summer there is power crisis, in majority of places.
Hence cleaning the floor using the conventional floor cleaning machines is difficult without
electricity. In this project an effort has been made to develop a manually operated floor cleaning
machine so that it can be an alternative for conventional floor cleaning machines during power
crisis.
Cleaning is essential need of this generation. Basically in colleges, industries, hospitals number
of users are more for them regular floor cleaning is required. Different techniques are used to
clean the different types of surfaces. The reasons for floor cleaning are.
1) Due to slips on the floors accidental injuries may occur.
                                               Page 1
                     Design and making of manual floor cleaning machine
2) To beautify the floor.
3) Debris and obstructions are to be removed.
4) Allergens and dusts are to be removed.
5) Surface wear to be avoided.
6) To make the environment sanitary (kitchens).
7) Traction should be maintained at optimum level, so that no slip will occur. The dust or water
present on the floor is scrub by the front two brushes. This dust and water is collected by the
vaccum cleaner and the detergent water is sprayed on the floor the mope present in the middle
section of the chassis perform rotary motion on the floor which cleans the dirt or dust. The
remaining water on the floor is wipe by the wiper present in end of the cleaning machine.
project deals with the design of new products. In recent years, floor cleaning and fabrication of
manually operated floor cleaning machine. The conventional floor cleaning and machines is
most widely used in airport platforms, railway platforms, hospitals, bus stands, malls and in
many other commercial places. These devices need an electrical energy for its operation not user
friendly. In India, especially in summer, there is power crisis and most of the floor cleaning
machine is not used effectively due to this problem, particularly in bus stands. Hence it is a need
to develop low cost, user friendly floor cleaning machine. In this project, an effort has been made
to develop a manually operated floor cleaning machine so that it can be an alternative for
conventional floor cleaning analysis of the floor cleaning machine was done using suitable
commercially available software. The conventionally used materials were ,considered for the
components of floor cleaning machine.
The floor cleaning machines are very much required in places like schools, colleges, hospitals,
bus and railway platforms, airport lounges, stadiums, parking areas, footpaths and many other
commercial areas, majorly because these places have large areas to be cleaned. These machines
can be manually operated, mechanically operated, fully automated, semiautomated, wire
controlled or remote controlled, fuel powered or solar powered.
These day’s humans lead a sophisticated life. People within the cities don't have regular and have
long working times. In such a situation someone will choose time saving methods. Thus robots
have taken the manual works. For career oriented and job going women it becomes hectic to
handle home and office together. Traditionally floor is cleaned with the assistance of mop or wet
mop using the hand as a possible tool. they need to clean hard on the surface. The cleaning
                                              Page 2
                     Design and making of manual floor cleaning machine
includes cleaning of varied surfaces basically cement floors, highly polished wooden or marble
floors. Among these floors the rough surface floor like cement floor, mostly present in semi
urban areas are covered with such a lot dust which needs longer for cleaning. For saving the time
the necessity was of House Cleaning Robot, which is an automatic system that works and cleans
on its own without human control/intervention. Autonomous robot for floor cleaning application
reduces much time in lifestyle. It performs sweeping and mopping tasks at a time, it also does
obstacle detection, and also has automatic water spray. Service robots are getting popular
recently these robots operate semi- or fully
   1.2 Objectives
   1. To achieve simultaneous dry and wet cleaning in a single run.
   2. To make the machine cost effective. Easy to operate.
   3. Requires no training to operate/ fast.
   4. No external power requires.
   5. Lower Maintenance Cost and Time.
   6. Required less cleaning time.
   7. High Cleaning Capability.
   8. Clean more space in less time.
   9. To reduce the maintenance cost of the manually operated floor cleaning machine as far as
   possible.
   1.3 Automatic type
   Fully automatic and Semi-Automatic machines available in the market are of high ranges and
   high weights. So, keeping the focus on weight as well as cost, they are not affordable to all
   such as organization committee of hotels, hospitals, hostels. Hence, there is need to design
   and develop a floor cleaning machine which is multi use and cost effective. In some places
   such as bus stations, temple halls, byres the floors are not regularly cleaned due to non-
   availability of machines. There is no machine in the markets which can be used on smooth as
   well as rough surface floors. Considering weight criteria, machine assembly, handling the
   machine is very flexible. This machine is affordable to all because of its uses and cost.
   Cleaning is the essential need of current time. Cleaning machines are very useful in cleaning
   floors, outside ground in hospitals, houses, auditoriums, bus stands and public places etc.

                 Design and making of manual floor cleaning machine
Many researchers have done so many works in evaluation of design of cleaning machine to
give better outcomes, but many researchers were operating their machine with the help of
any external source like electrical energy, but this machine has been designed in such a way
that it can be operated by manual power and there is no need of electric energy or any other
energy. For the above said purpose the manual power is transferred from the chain socket to
the gear through chain mechanism then its power transfer to bevel gear and it result to rotate
the wheels and floor cleaning work is performed, which makes this machine completely
manually operated without any external source of energy and its manufacture, and design is
also cheaper in cost and reliable for everyone. It is capable for the cleaning purpose of both
dry and wet floor and easily transfer from one place to other due to its light weight and
simple design. Also, a benefit is that it is environmentally friendly. The components have
been used in designing this mechanically operated floor cleaning machine are steel bar, bevel
gear, wheel, wooden clips, bearing, rod, wiper, chain socket, gear. Building maintenance is
often characterized by an infinite series of drab, unclean, timeconsuming, and unpleasant
duties such as floor was Various researchers have worked on floor cleaning machines and
related properties, and a light has been thrown on some of the recent works done by different
scholars. A cleaning machine for the floor was designed and prepared a 3D model of their
project or, say, a machine in the modeling software and then analyzed by applying boundary
conditions as their project conclusion and found that the level of stress on a handheld
machine is within the safe range. A Street Cleaning Machine operated by Tricycle was
manufactured. This research article depicts that it has been made for most use in rural areas
and concluded that cleansing is working less when the road seems too heavy again damaged.
A multi-use floor cleaning machine using A.C. induction Motor and speed reduction method
was designed and manufactured. The machine produced was highly efficient and showed
flexibility. The operational capacity of the given mechanical project is also fulfilled by using
the machine; the process of cleaning the floor can be done quickly and easily in an effective
manner. An automatic floor cleaner using a Direct Current Motor and configured a wiper
mechanism was designed and fabricated. The proposed machine produced shows flexibility
and laboriousness. Successful utilization of Solar Energy saves electricity. The main aim for
this project is achieved, and using the device, floor cleaning can be done quickly. In 1868,
the first W. McGuffey in Chicago. In the late 1990s & early 2000s, many different
                                          Page 4
                Design and making of manual floor cleaning machine
companies came into the market to develop robotic vacuum cleaners. But again, the only
problem with these cleaning devices is the consumption of electricity for operating them. A
floor cleaning machine that was manually operated, which is simply a bicycle working on the
same concept up to some extent. But this project lacks efficiency with a high margin of error.
Besides the fact that it was not so efficient, it deals with the problem that women could not
operate it as efficiently as men. Effective cleaning and sanitizing play an essential role in
human beings’ health . Several studies on human-robot interaction with floor cleaning robots
have been published. Fink et al. describe ethnographic research of floor cleaning robots
conducted in various residences over six months. User perception, usage analysis, and social
activities involving cleaning robots are all thoroughly researched in their research. Sakamoto
et al. offer a computer screen interface for engaging with a floor cleaning robot based on
stroke gestures. Their experiments show that the proposed interface can manage a cleaning
robot and obtain various views from ceiling cameras. Based on a bioinspired neural network
technique, Luo and Yang suggest multi-robot cooperative sweeping. The authors investigate
the total coverage and path planning challenges associated with unstructured workspaces
using many cleaning robots. Another critical study describes a cellular decomposition
method for dividing a cleaning space into cells and providing a good coverage plan for two
indoor floor cleaning robots over the cells. With the market for floor cleaning robotic goods
increasingly crowded, interest in benchmarking various automatic systems has developed.
Rhim et al. present performance indicators for autonomous cleaning robots. Most cleaning
robots identify independent mobility, dust collection, and operating noise as essential
performance indices. Wong et al. propose and validate two criteria to capture robotic
cleaning performance and coverage efficiency . Cleaning is a physically demanding and
labor-intensive job. Cleaners frequently use heavy powered tools (e.g., buffing
machines/floor polishing machines, wet and dry vacuums) in addition to a variety of
physically demanding tasks such as mopping, wiping surfaces, polishing, and heavy manual
handling (e.g., carrying and emptying rubbish, moving furniture, filling, taking, and
emptying buckets of water), often under time constraints. According to several studies,
cleaning activity is physiologically stressful for both the cardiorespiratory and
musculoskeletal systems. Cleaning chores have a high degree of physical demand, including
high aerobic strain, static muscle loads and repeated motions (ibid), a high frequency of
                                          Page 5
                      Design and making of manual floor cleaning machine
    undesirable postures such as stooping and crouching , and a subjective sensation that the
    labor is stressful. Furthermore, various studies have identified psychosocial risk factors
    associated with cleaning labor, such as a lack of control over work and breaks, a heavy
    workload, and time constraints Several studies have found that cleaners are at a high risk of
    developing health issues, notably musculoskeletal issues that impact the back, neck,
    shoulders, elbows, and hands. Among the many occupations studied, female domestic
    servants had the worst health. A high frequency of neck and shoulder issues in a study of
    Swedish cleaners' musculoskeletal disorders was discovered. Other research has shown
    similar difficulties that have resulted in high absenteeism. A survey of Danish female
    cleaners revealed a considerably greater 1-year frequency of musculoskeletal complaints than
    an age-matched control group.
    Although there have been multiple precedents demonstrating the benefits of deploying floor
    cleaning robots to maintain constructed structures, standard platforms have performance
    issues. Their fixed morphological design, which severely limits their navigation and access, is
    a primary contributor to their performance shortfall. The designed robot can change its
    morphology to seven one-sided tetrominoes in reaction to its sensed environment to maximize
    its coverage area. This research examines the coverage area performance of the robot and
    compares it to two widely available fixed morphology robot platforms. The traditional
    mechanically operated floor cleaning machine is most used in road, school, house, bus stand,
    mall, airport and other commercial place. This machine does not require any type of external
    source of energy for its operating. The aim of present work is to design and develop process
    for cleaning the dry as well as wet floor manually. This mechanically operated floor cleaning
    machine is designed by keeping the basic consideration for reduction in cost and efforts while
    being environment friendly and easy to handle.
    1.4 Reasons of Floor Cleaning
he principal reasons for floor cleaning are:
    To prevent injuries due to tripping or slipping. Injuries due to slips and trips on level floors
     are a major cause of accidental injury or death. Bad practice in floor cleaning is itself a major
     cause of accidents.
    To beautify the floor.
                                                Page 6
                      Design and making of manual floor cleaning machine
   To remove stains, dirt, litter and obstructions.
   To remove grit and sand which scratch and wear down the surface.
   To remove allergens, in particular dust.
   To prevent wear to the surface (e.g. by using a floor wax or protective sealant).
   To make the environment sanitary (e.g. in kitchens).
   To reduce ingestion/inhalation rates of microplastics.
   To maintain an optimum traction (e.g. for dance floors).
   Reduce workload in between shifts (e.g. dedicated cleaning crew).
    1.5 Methods of Floor Cleaning
The treatment needed for different types of floors is very different.
Slipping is a common safety hazard for cleaning methods that involve water or other liquids,
especially if the floor is left wet.
Sawdust is used on some floors to absorb any liquids that fall rather than trying to prevent them
being spilt. The sawdust is swept up and replaced each day. This was common in the past
in pubs and is still used in some butchers and fishmongers.
It used to be common to use tea leaves to collect dirt from carpets and remove odours.
There are also a wide variety of floor cleaning machines available today such as floor buffers,
automatic floor scrubbers and sweepers, and carpet extractors that can deep clean almost any
type of hard floor or carpeted flooring surface in much less time than it would take using a
traditional cleaning method.
    1.5.1   Wood flooring
Different types of wood flooring may require completely different care depending on whether
they are waxed, oiled or have a polyurethane coating. It is important to determine the type of
finish of a wood floor and always treat it in the proper manner, for instance it is difficult to clear
wood floor wax from a floor coated with polyurethane. Simple cleaning instructions:
    1. Clear the floor of any furniture that is easy to move.
                                               Page 7
                  Design and making of manual floor cleaning machine
2. Sweep or vacuum all loose dirt and debris.
3. Mop the floor, going along with the grain. For a polyurethane coated floor, dampen a
    mop with water and a few drops of dishwashing liquid. Be sure to ring out the mop
    thoroughly before using it on the floor. Run the mop back and forth, going with the grain
    of the wood in smooth strokes. Do not use water for lacquered or shellacked floors, as it
    can stain the wood and cause buckling.
4. Buff the floor with a soft cloth to remove any soapy residue. Cloth diapers work well for
    buffing since they are very soft and absorbent.
1.5.2   Tile and Stone
Tile and stone flooring is common in kitchens, stairs, and bathrooms. Its cleaning process can
be divided into three steps:
Dirt or dust should first be removed with a vacuum cleaner or a broom.
Have a floor cleaning solution or spray bottle for the appropriate floor. If you are cleaning
stone floors (marble, granite, travertine, etc.), make sure the cleaning agent states that it is for
stones. An acidic tile cleaning solution can be used on ceramic and porcelain floors
After spraying the tile or stone floors in a small area, use a mop to clean and scrub floors.
Then wipe it with dry cloth.
1.6 Reducing the need for cleaning
A well-maintained entrance matting can dramatically reduce the need for cleaning. For
public and office buildings, about 80 to 90% of the dirt is tracked in from outside. Installing a
total of 15 feet of matting consisting of both indoor and outdoor sections will remove about
80% of this. Thus, about two-thirds of the dirt can be removed at the entrance.

                     Design and making of manual floor cleaning machine
    the help of chain drive. The rear wheel having a big chain sprocket.
3.3.   Sprocket Chain Drive
    is relatively easy to install. Assembly tolerances are not as restrictive as those for gear drives.
    Chain drives are a better choice for less experienced builders working with a minimum of
    machine tools. Sprockets are used in bicycles, motorcycles, cars, tracked vehicles, and other
    machinery either to transmit a track, tape etc. Early automobiles were also largely driven by
    sprocket and chain mechanism, a practice largely copied from bicycles. We use sprocket
    chain mechanism because of following some advantages;
    1. Chain drive has maximum efficiency it is positive drive.
    2. Chain drive can be readily redesigned and reconfigured rotary motion between two shafts
    where gears are unsuitable or to impart linear motion to
    in comparison to gear drive system.

3.8.   Working methodology
       Cleaning machine is very much useful in cleaning floors and outside ground in hospitals,
       houses, auditorium, shops, bus stands and public places etc. Many of floor cleaning
       machines are available but we developed machine is a very simple in construction and
       easy to operate. Anybody can operate this machine easily. Hence it is very useful in
       hospitals, any large area space. The time taken for cleaning is very less and cost is also
       very less. Maintenance cost is less. In our project we have made the machine to operate in
       a fully mechanical way. The floor cleaner is very simple in a construction and very easy
       to operate, anyone can operate it. Without any prior training of any sorts with safety.
       Machine consist of rollers ,water tank, sprocket & chain mechanism, collector brush
       assembly, drive wheel, and cotton etc. cotton is wound around supporting roller and main
       rollers. but main roller is placed in water tank so that wetted cotton is transfer forward for

3.9.   Methodology
       The system is assembled with a pair of existing wheels that rotates with the help of a
       shaft. The shaft and wheels are joined together. The wheels provide power to the gear
       through the chain mechanism, and the bevel gears are connected perpendicularly. The
       help of bevel gear rotates the brush. The revolutions start to move when we exert forces
       on this machine manually. As the wheel starts spinning, it becomes straightforward to
       move it forward or backward, and as the lower end of the machine is installed with a
       brush, the brush starts operating, cleaning the surface where it is interacting

       hain drive, Device widely used for the transmission of power where shafts are separated at
       distances greater than that for which gears are practical. In such cases, sprockets (wheels
       with teeth shaped to mesh with a chain) take the place of gears and drive one another by
       means of a chain passing over the sprocket teeth. The chains used in conveyor belts are
       commonly block chains, and consist of solid or laminated blocks connected by side plates
       and pins. The blocks engage with teeth on sprocket wheels. Depending on the material
       being moved, buckets, hooks, or other devices are connected to the blocks.

                                  CONCLUSION
Manually operated floor cleaning machine is an alternative for an automated floor cleaning
machine during power crisis. The equipment purposely design for cleaning floors, but can
only be use in outdoors with large ground like the hospitals, bus stands, railway stations etc.
The equipment will result more beneficial when it is compared to other existing floor
cleaning machines. Our project is based on very simple chain drive mechanisms which can
be easily operated by any person. Any fault in machine can be easily identified and can be
corrected on the spot.
