Bonnet/Spin Pad Cleaning

Bonnet/Spin Pad Cleaning

Theory

Bonnet cleaning is commonly referred to as a "dry" carpet cleaning system. Although not completely dry, bonnet cleaning is considered a low moisture carpet cleaning system. Bonnet cleaning is accomplished by spraying a detergent/solvent solution over the face of the carpet pile. This can be done with hand pump style sprayers, power sprayers, CO2 pressure tanks or specialized spray systems attached to the floor machine. Immediately after spraying, the carpet is buffed with an absorbent pad attached to the machine. The carpet soil is absorbed into the pad. The pad is changed as it becomes soiled and thoroughly laundered prior to the next job. Best results are obtained when the pads are changed before becoming too wet.

Advantages

• The bonnet system is a relatively fast system enabling the operator to cover large areas quickly.
• Bonnet cleaning is relatively fast drying.
• Minimal operator skill required.
• Excellent system for maintenance programs when used in conjunction with more thorough periodic soil extraction methods.

Disadvantages

• Bonnet cleaning is not noted for heavy soil removal.
• No rinsing action.
• Does not provide deep cleaning action.
• Used absorbent pads require laundering between jobs.
• High/low swirls figure 8 pattern if not pile set after procedure.
• Caution must be used on cut pile carpet.

Many bonnet cleaning solutions that may clean effectively will leave soil attracting residues. Use a bonnet cleaner with a soil retardant to enhance bonnet cleaning effectiveness. Best results are achieved by using a dry bonnet, and regularly changing the bonnets when soiled.
