Product Overview
The Miele PWM 508 Mop Star 80 is an 8kg Little Giants commercial washing machine designed for facility management, contract cleaning and sites processing mops, cloths and cleaning textiles.
This model is available in four main variants: drain valve or drain pump, each with 230v, 13A and 230v, 25A power options. For regular mop washing, a&f would normally recommend the drain valve version because its DN 70 outlet is better suited to handling coarse soiling and larger particles from mop heads.
The drain pump version can still be a useful option where the machine is replacing a domestic washer or processing lighter items such as microfibre cloths, but it should not be the first choice where heavily soiled mops or larger debris are expected.
With dedicated mop and cloth programmes, patented pre-spin, a 73 litre drum and high-speed 1,400 rpm extraction, the PWM 508 Mop Star 80 is built to support consistent cleaning results in a compact commercial footprint.

Features and buyer benefits
A practical overview of the PWM 508 Mop Star 80 features that matter most in daily use, including mop and cloth programmes, drain choice, hygiene support, extraction, dosing and connected laundry options.
Mop Star programmes
Special programmes for mops and cleaning cloths
Purpose-built programme options help cleaning teams process mops, microfibre cloths and related cleaning textiles more consistently than a standard commercial washer.
Drain valve option
DN 70 drain valve is the preferred mop-washing choice
The drain valve version is better suited to mop-heavy use because larger particles and coarse soiling are less likely to cause drainage problems than with a pumped waste setup.
Drain pump option
Useful where a pumped waste connection is needed
The drain pump variant can work well for lighter cleaning textiles, microfibre cloths and domestic-replacement applications where heavy debris from mop heads is not expected.
Patented pre-spin
Helps remove dirt before the main wash phase
Miele’s patented pre-spin supports improved soil removal, helping the machine deal with the dirt and residue commonly found in mop and cloth processing.
8kg capacity
8kg load with a 73 litre honeycomb drum
A compact but capable size for facility management and contract cleaning sites, with enough drum volume for mop and cloth loads while retaining a small footprint.
Hygiene support
Tested hygiene performance with disinfection rinse
The product sheet lists tested virucidal efficacy, proven hygiene and a disinfection rinse, supporting controlled hygiene processes where the correct programme and site procedures are used.
High-speed extraction
1,400 rpm spin with 535 g-factor
Strong extraction helps reduce retained moisture after washing, easing drying demand and improving laundry flow where mops and cloths need to return to use quickly.
Cloth processing
Residual moisture as low as 20% for cleaning cloths
For cleaning cloths, the listed residual moisture figure is especially useful where cloths need to be prepared efficiently without unnecessary drying time.
Hot water connection
Hot and cold fill can improve cycle performance
Where a suitable hot water supply is available, the machine can reduce energy demand and shorten relevant programme times compared with cold fill only.
M Select controls
Simple rotary control with clear programme guidance
The language-neutral fascia and clear programme sequence display help staff select the right cycle with less training and fewer day-to-day mistakes.
Dosing ready
Up to 6 liquid dosing pump connections
Optional liquid dosing supports consistent chemical use, better process control and a cleaner staff routine where professional detergent systems are required.
Connected laundry
Optional LAN/WiFi module and WiFiConn@ct
Connectivity options can support remote status, operating data and connected laundry management where the correct module and Miele Professional software setup are specified.

Choosing the right machine
Is the Miele PWM 508 Mop Star 80 the right model for me?
The Miele PWM 508 Mop Star 80 is a strong choice where a compact 8kg commercial washing machine is needed for mops, microfibre cloths and cleaning textiles. It is designed around facility management and cleaning environments, with specialist programmes for mops and cloths.
The key choice is drainage. For regular mop processing, the drain valve version is normally the better option because the DN 70 outlet is more suitable for coarse soiling and larger particles. The drain pump version is better treated as an option for lighter items, domestic-replacement applications or microfibre cloths where heavy dirt and debris are not expected.
When is this machine a good fit?
This model is a good fit where a site needs a compact professional washer for cleaning textiles rather than a general domestic-style machine. It is especially relevant for cleaning contractors, facilities teams, property management sites and organisations that regularly wash mops and cloths.
- Suitable for sites needing an 8kg professional washer for mops and cleaning cloths.
- Useful where mop-specific programmes and patented pre-spin are required.
- Good for compact laundry rooms where a larger washer is not practical.
- Suitable for facilities teams that need repeatable cleaning routines for mop and cloth processing.
- Can be specified with drain valve or drain pump, depending on the drainage and workload.
What should I check before choosing this model?
The main checks are drainage, power supply, workload and the type of textiles being washed. For mop-heavy use, drainage should be considered before price or convenience because the wrong drain type can create avoidable reliability problems.
- Choose the drain valve version where mops are regularly washed and coarse soiling is expected.
- Only choose the drain pump version where the load is lighter, cleaner and suitable for a pumped waste setup.
- Confirm whether the site has a suitable low-level drain for the drain valve version.
- Check whether the 230v, 13A or 230v, 25A version is the better fit for the site’s electrical supply and wash turnaround needs.
- Confirm that an 8kg capacity is large enough for the daily mop and cloth workload.
When might another model be better?
A different model may be better where the workload is larger, where the site needs a more advanced control system, or where laundry flow depends on higher daily throughput.
- Consider a larger Mop Star or Benchmark washer if mop volumes regularly exceed an 8kg machine.
- Consider a larger drain valve machine where heavy debris and high mop volumes are routine.
- Consider a different commercial washer if the site mainly processes general laundry rather than mops and cloths.
- Consider a more specialist hygiene or infection-control configuration where the site has formal decontamination requirements.
- Consider a full site survey if the existing drainage, floor construction or electrical supply is unclear.
Services, utilities and installation checks
This model is available in drain valve and drain pump versions, with 13A and 25A power options. The right setup depends on the site services, drainage route and required wash turnaround.
- Load capacity: 8kg with a 73 litre drum.
- Drain valve version: DN 70 dump valve, normally preferred for mop processing.
- Drain pump version: DN 22 drain pump with fine filter, better suited to lighter soiling and suitable pumped waste applications.
- Power options: 230v, 13A or 230v, 25A depending on variant.
- Water connection: hot and cold water connection should be planned during installation.
- Dimensions: 850(h) x 596(w) x 714(d) mm.
Replacing an older model?
If this machine is replacing an older commercial washer, the most important checks are drainage type, capacity, power supply, available space and whether the site has moved from general laundry into regular mop and cloth processing.
Older machines may have different drainage arrangements, electrical requirements and cycle behaviour, so a like-for-like swap should not be assumed without checking the site.
General PWM 508 family historic search terms include PW6055, PW6065, PW5064, WS5425, WS5405, WS5105, WS5426, WS5406 and W406. These should be treated as historic search references for the PWM 508 family, not as a direct guarantee that every previous installation is suitable for this Mop Star variant.
Compliance, hygiene and environment
The product sheet lists tested virucidal efficacy, proven hygiene and a disinfection rinse, but the correct hygiene outcome depends on the programme used, chemical process, staff handling, segregation and the site’s written procedures.
- Suitable hygiene claims should be matched to the site’s process and risk assessment.
- For healthcare, care, veterinary or infection-control settings, the full laundry process should be reviewed before specifying equipment.
- The drain valve version is normally more appropriate where mops may carry coarse dirt or larger particles.
- The product sheet lists WRAS, UKCA, CE, VDE, VDE-EMC, WEEE and IPX4 splash-proof safety rating.
- a&f can help confirm the right variant, drainage, electrical supply and ongoing service support before ordering.
