## Questions & Answers

**Q: Does it come with the hose reel in picture?**
A: Yes

**Q: Can i replace teh chemical injector on the model 95002 If so what is the part number?**
A: Yes, there are rebuild kits available for the injector on the CAT pump. Please reach out to our customer service team at 877-362-4271 or email us at productsupport@simpsoncleaning.com. Please have your CAT pump number available when you contact the customer service team. Thank you!

**Q: Can the water tank be used for batch mixing or is it strictly a buffer tank?**
A: It's your tank. Do with it as you wish, but I would not recommend it as you will eventually be running SH and soap through your pressure washer pump and it kill it.

**Q: Is there anywhere to carry a surface cleaner?**
A: it should fit between the machine and water tank
