Coffee grounds container Solis 97843 — compatible with Solis machines, black stainless steel

The Solis 97843 coffee grounds container is a replacement knock box designed to collect spent coffee pucks and grounds in a tidy, compact unit. Finished in black stainless steel, it is intended to sit beside compatible Solis espresso machines and keep the work area clean while allowing quick disposal of residues.

Advantages

The container combines a stainless steel housing with a removable plastic insert that is dishwasher-safe for easy cleaning. A rubber-covered knock bar absorbs impact to protect the portafilter and reduce noise, while non-slip feet keep the unit stable on the countertop. With a 700 ml capacity and a high back to prevent splashing, it minimises the need for frequent emptying and helps avoid mess.

Suitable for

• Home baristas using Solis Perfetta or compatible espresso machines
• Small offices or domestic kitchens where compact waste collection is preferred
• Anyone who wants a dedicated container for used portafilter pucks and grounds

When it may not be suitable

This container is designed for use with compatible Solis machines and similar domestic portafilters; it may not fit commercial or unusually large portafilters. If you require an integrated waste system for a commercial espresso machine or very high daily volume, a larger or purpose-built solution could be more appropriate.

Key specifications

• Material: black stainless steel housing with removable plastic insert
• Capacity: 700 ml
• Knock bar: rubber-covered shock-absorbing bar
• Cleaning: plastic insert suitable for dishwasher cleaning; housing washable by hand
• Base: non-slip feet to reduce movement and noise
• Design: high back to prevent splashing; cut-out front for horizontal knocking

How to use

Place the knock box next to your espresso machine at an accessible height. After extracting a shot, hold the portafilter over the cut-out front and tap the portafilter against the rubber-covered knock bar to release the spent puck into the container. Remove the plastic insert when full or for cleaning; the insert is dishwasher-safe or can be rinsed by hand. Reassemble the parts before next use.

What to consider before purchase

• Check compatibility with your espresso machine's portafilter size and shape
• Consider whether a 700 ml capacity meets your daily disposal needs
• Decide if a freestanding knock box suits your counter space or if a larger/ built-in solution is required

Usage recommendations

For best results, empty and rinse the insert regularly to prevent odour build-up, and use the rubber-covered knock bar to protect the portafilter. Adjust your machine or grinder settings if residues consistently appear wet, indicating extraction issues.
