Warnings from the manual
- Never use flammable liquids such as alcohol, acetone or petrol
- Do not use bleach or strong acids
- Keep items off the bottom of the tank – use a basket
- The heater holds 52–65 °C; with the lid on it can get hotter
- Do not use deionised water – it cavitates poorly
Notes
Input power 95 W, 150 W with heater (the heater's share is not stated). The heater heats to about 145 °F (63 °C) and is optional on some versions. 60-minute timer, drain with several positions, ABS lid. The inner tank's metric measures on the page do not add up; the mm values are converted from inches. The manual covers the models Q90–Q650, PC3 and SweepZone. Verified 2026-10-30 (the page says the optional heater heats to 145 °F; the manual states 52–65 °C, so the maximum of 65 °C is kept).
