What are common problems with used scrubbers?

Used scrubbers can exhibit a variety of problems, from mechanical failures to hidden wear from inadequate maintenance. The most common problems are brush problems, vacuum motor defects, battery-related failures and water pump issues. By recognizing these problems before you buy, you can avoid unexpected repairs and make a better investment.

What mechanical problems are most common with used scrubbers?

The most common mechanical problems in used scrubbers are brush problems, vacuum motor failures, water pump failures and electrical problems. These parts experience the most wear from heavy use and can cause unexpected repairs if not recognized in time.

Brush problems often manifest themselves as uneven cleaning or vibration during scrubbing. Brush motors can wear out due to overloading or using the wrong brush types. Suction motors often fail due to clogged filters or sucking up large amounts of dirt without regular cleaning.

Water pump issues are usually caused by scale deposits in the pipes or damaged seals. This results in reduced water pressure or complete failure of the water system. Electrical failures come in the form of faulty switches, damaged wiring or control panel problems.

Battery problems are a separate category but are often the most invasive to repair. Old lead-acid batteries can lose capacity due to inadequate maintenance, while lithium batteries require a significant investment to replace despite their longer life.

How do you recognize wear on critical parts before you buy?

At a used scrubber always the brushes, rubbers, filters, batteries and water tanks for wear and tear. A visual inspection of these parts gives you instant insight into the machine's maintenance history and future maintenance needs.

Start by checking the brushes for uneven wear or damage. Feel the bristles - they should be firm and not fall out under light pressure. Examine the suction rubbers for cracks, deformations or hard spots that can be caused by chemical cleaners.

Test the battery by turning the machine on fully and seeing how long it holds its charge. For lead-acid batteries, look for white rash around the terminals, indicating leakage. Gel and lithium batteries are more difficult to assess visually, but a shorter operating life than specified indicates wear.

Check filters for contamination and damage. Blackened filters indicate heavy use without regular replacement. Inspect water tanks for cracks, scale or rust. Test all knobs and switches to rule out electrical problems.

Always ask for a demonstration where you can operate the machine yourself. Watch for strange noises, vibrations or irregular movements that may indicate mechanical problems.

What are the typical maintenance aspects of a used scrubber?

The annual maintenance of a used scrubber includes Regular replacement of wear parts and preventive care. This includes replacing brushes, vacuum rubbers, filters and periodic battery replacement. Walk-behind models require less intensive maintenance than ride-on scrubbers.

Regular maintenance parts consist of replacing brushes, suction rubbers and filters depending on the machine model. These parts have a life of 3-12 months under normal use and are essential for optimal performance.

Battery replacement is often the biggest maintenance expense. Lead acid batteries last 2-4 years with proper maintenance, while gel batteries last longer but require a higher investment. Lithium batteries have the longest lifespan of 5-8 years.

Unforeseen repairs can range from minor electrical adjustments to complete motor replacement. Machines older than 5 years have higher chances of more intensive repairs. Preventive maintenance by a specialist often prevents more complex problems.

Intensity of use greatly influences maintenance requirements. Daily use in dusty environments doubles filter and brush wear compared to occasional use on clean floors.

What problems arise from inadequate maintenance by the previous owner?

Overdue maintenance caused scale in pipes, clogged filters, damaged seals and battery problems that seriously affect performance. These problems are often hidden but can lead to intensive repairs shortly after purchase.

Lime scale builds up when water tanks and pipes are not cleaned regularly with proper cleaning agents. This reduces water pressure and can damage pumps. Clogged pipes are difficult to clean and often require professional cleaning or replacement.

Battery problems caused by poor maintenance have a major impact. Lead-acid batteries that are regularly drained or not refilled with demineralized water permanently lose capacity. This means shorter operating time and more frequent replacement.

Damaged seals from the use of improper chemicals or lack of lubrication lead to leaks. Water in electrical components can cause short circuits. Old lubricants become sticky and impede moving parts.

Neglected filters allow dirt to get through to sensitive components such as motors and pumps. This accelerates wear and tear and can lead to complete failure. Dirty machines also have a shorter service life because dirt and dust impede the cooling of motors.
